An object-oriented programming language (also known as OO language) is one that allows a website development service to use object-oriented programming techniques including inheritance, modularity, polymorphism and encapsulation. The first language to boast primary features of an object-oriented programming language was the Simula. The Simula was released in 1967 followed by Smalltalk, which was in huge demand between 1972 and 1980. In fact, Smalltalk is one of the best examples of object-oriented programming.

Pure OO languages have everything in them treated as an object. From primitives to prototypes, classes, blocks and modules, these languages were designed to enforce and facilitate OO methods. Examples of pure OO languages include Eiffel, Ruby and Smalltalk.

A custom web development expert employs object-oriented programming languages in the web development process. Here are some features of Object-oriented programming languages in website development services:

Quick Turnaround Time: OO languages have a comprehensive code library that a programmer employs in developing websites. With an extensive code library, the programmers can develop web sites in a quick, competitive and economical manner.

Quick Output: The coding under Object Oriented programming language is highly systematic and organized. Programmers can on a project with ease without affecting the pace of web page development.

Objects and methods developed can be reused in other programming languages: Object oriented programming ensures development of reusable code library. Programmers can reuse the objects, block and modules in other projects and programming languages.

Modern-day Object Oriented programming languages run on Windows, Mac OS, Linux/Unix operating system, Palm Handhelds and .Net virtual machines. Here are some benefits of using a modern-day object oriented programming language in websites development:
OO programming languages have a very clear and readable syntax
They boast exception-based error handling techniques
They feature high level and dynamic data types
There is a natural expression of procedural code
OO languages include high level third party modules and extensive standard libraries

Most OO languages are flexible enough to handle any domain problems. Some OO languages such as Python allow programmers to build web servers in three lines of code. This ensures error-free web development.

Did you know computer equipment continually gives out small amounts of different gases and fine dusts? Some people are highly sensitive to these.

Plastic PC components are one source, as most plastics are unstable and break down naturally over time, especially when exposed to ultraviolet light and sunlight. (That’s the reason why they turn yellow and get brittle.)

Another source comes from vapour produced from traces of manufacturing materials slowly evaporating.

The gases and fumes given off are called ‘out-gassing’ and only occur in small amounts. But when the equipment is new, the out-gassing is greater and noticeable even to people who aren’t particularly sensitive.

This is similar to the smell that we get when we first get into a new car – out-gassing from the vinyl, plastic carpet and hard plastic interiors, as well as the wiring.

A new computer has a similar smell. So to some extent you can avoid outgassing, at least of ‘new’ volatile components, by buying a good quality ‘used’ PC.

Other office materials, particuliarly new furnishings, may also outgas – chipboard contains phenolic resins, which release trace amounts of formaldehyde; also carpeting (especially foam padding), paint and fabrics give off obnoxious chemicals when new.

People who have been sensitized (by previous exposure) may react badly to even very tiny amounts of these gases, by getting headaches, dizziness, and respiratory problems. The problems may persist even when the original cause is reduced, or disappears. In such a case it’s wise to seek qualified medical advice.

Casings may also be contaminated by fine brominated phenolic dust originally put on as a fire retardant, which can be blown out by fans, circulation or movement.

The best solutions are :-

– Initally, to run any new equipment in an empty well ventilated room to allow most of the outgassing to occur before use.

– Always work in a room with good ventilation and avoid continual high room temperaturesoutgassing will increase as the temperature rises.

Laser printers emit a lot of toner dust, which contains carbon and solvents, and quite a few people are sensitive to it. You can smell it when the printer is on, and especially on freshly printed-paper. You may notice wheeziness, coughing, and sneezing.

People working at copy centers and service bureaus often suffer from headaches, and toner dust is the main suspect. NCR paper (‘carbonless’ paper) can also cause wheeziness.

Good ventilation, drawing air away from the operator and filtering out particles, will help reduce these reactions, but effective ventilation in a commercial or home office is sometimes hard to achieve, especially in sealed buildings.

You can try going outdoors and breathing deeply for 10 minutes every hour or so. Open doors, maybe have a fan on., and avoid routine (multiple) photocopying every single document.

Think long term. Removing even mild poisons from your environment is yet another way to keep safe, stay fitter at the PC and enjoy a healthy computing career!

A computer network is the practice of linking two or more computing devices together to exchange information. Networks are built with a mix of hardware
and software. This network is to share services and communicate via a communication link.

A computer network is very useful in a business. Most companies have over time more of a team and is often very beneficial to the network for all computers in the office. Local Area Network (LAN) equipment to your company. It’s about sharing and exchange different types of information as possible. If there are networks of computers, you hear these reasons.

There are different types of computer networks. A computer can be as simple as connecting two computers or a computer and a printer, or it can be very complex, connecting millions of computers and peripherals. Here is a list of different types of equipment.

The smallest type of network is a Personal Area Network (PAN). This type of computer network to connect a computer to a series of devices. These devices may include, but are not limited to, printers, PDAs and phones. Typically, these are very close to a computer. a Local Area Network (LAN) is a network of small geographical used. An example of this type is a computer network with two or more computers or computers that are connected to a workstation. A version of a LAN is a Wireless LAN (WLAN).

A Campus Area Network (CAN) is ideal for a university, but also occur in industrial plants. This type of computer network between computers in several buildings. This is usually used for bridging and routing. A Metropolitan Area Network (MAN) is a set of interconnected LANs and WANs, but will not extend certain restrictions, such as a city, town or city. Many of them operated in the public schools and used by companies and individuals in the region.

A Wide Area Network (WAN) is a step in a man what kind of computer network that crosses metropolitan or even national boundaries. The most popular WAN is the Internet. This computer network routers and public communications links used for data transport. Many WAN operated by private companies and limited, unlike the Internet. Although these species are the MAN network, computer users most of the other by the size of a Desk Area Network (DAN) on a very Large Global Area Network (GAN).

Some science fiction writers envisioned a world overrun with robots by now. Well, thats hardly the case, unless youre talking about specialized areas of industry, including robots that have helped with the safety and overall effectiveness in demolition projects.

For more than three decades, robotic equipment increasingly has been used in demolition and construction projects around the globe. There has been no need for a man vs. machine contest of superiority. Nor has there been fear of a robot rampage as in the science fiction film, I, Robot. Rather, people and machines work together as humans operate remote controlled machines in cutting, breaking, crushing and other demolition tasks.

While the popular image of demolition is the implosion of buildings with explosives, this is hardly what happens in the vast majority of all demolition projects. The National Demolition Association reports implosions account for less than 1 percent of all demolition work.

Demolition mostly involves the step-by-step destruction of an entire building or partial structure in often hazardous conditions, whether the wrecking ball or robotic demolition equipment is used.

Demolition practices today are not only quicker but safer and more cost-effective, according to the National Demolition Association, which represents more than 1,000 U.S. and Canadian companies that offer standard demolition services as well as a full range of demolition-related services and products.

In 2008, BBC reporter Steven McKenzie explained how a small army of robots was deployed in the clean-up of a Scottish nuclear complex. He said like WALL-E, the star of the Pixar animated film set in a waste-covered Earth of the future, the machines in Scotland were tackling manmade waste.

The real-life robots have been working in highly radioactive areas of Dounreay in Caithness in the Highlands, he said.

A spokesperson for the project said: “Using remote tools such as the Brokk 180 can complete some physical decommissioning tasks more quickly than human workers, and without exposing them to the hazards. The Brokk was used in smashing down walls. For a person to do that they would have to wear an airline suit and a sledge hammer.”

Benefits of using robotic demolition machines include:

Remote Controlled: Safer to operate
Electric Power: No Fumes
Compact Size: Accessibility to tight spaces
Light weight: Easy on floors
Multiple tools: Always jobs for machines

In June of 2009, Construction News Portal reported R. Baker & Son All Industrial Services Inc., a specialized demolition contractor, completed an eight-phase, highly technical, demolition and environmental remediation project at Kings County Hospital located in Brooklyn, N.Y.

Demolition crews utilized various hand tools to accomplish the demolition as well as specialized demolition equipment which included skid steers with demolition hammer and bucket attachments and Brokk 90 hydraulic breakers, Construction News Portal said.

Web hosting organizations that provide a connection, storage and services by means of a secure and hack resistant server using https and SSL certificates are regarded as to be a secured hosting service. SSL stands for secure sockets layer and is currently probably the most widely accepted protocol in world wide web security. SSL is utilized in conjunction with https, hypertext transfer protocol secure. Https encrypts communication over the net and secures the network web server. Secure server hosting can be a common theme among e-commerce web sites and other websites that accept payments of any form.

Credit card numbers and other extremely sensitive info might be given and transferred over the world wide web in a secure manner. When an internet user connects to a web site employing SSL, the secured server is asked to confirm its identity. This security measure was put in place to guarantee third parties cannot tamper with or eavesdrop on a secured web site, essentially stealing confidential data. In order for this to take place, the web users browser need to have the ability to accept SSL certificates. Currently, most internet browsers are set up to deal with confirmations by default including well recognized browsers like Net Explorer and Firefox.

When picking a secure internet hosting plan it can be critical to take into account storage space, disc space, information transfers, databases and operating systems. The server ought to have the ability to store and transfer information at rates suitable for the client as a way to maintain the site running at a steady and reliable pace. The operating system running the server, whether or not it really is Unix, Linux or Windows must also be regarded as. Other functions to check into are additional space and transfer, E-mail, scripting language, CGI-Bin (custom or prepared), Front Page (extensions for FP), IP Address (unique number), Log Files (line by line detail), Statistics (summaries) and functions included within the control panel.

Its also important to think about set up time. How long it will take to obtain a website up and going as soon as connection to the server has been established? Furthermore to set up time, price consideration is just as critical. What are the payment terms and how much are the fees? Make a checklist of ought to have functions and select a secure server hosting plan that consists of them all.

If you want to get a BS degree in computer science, you will need to complete approximately four years of schoolingthe same as for any bachelors degree. There are different types of schools that offer these computer degrees, ranging from online schools to technical schools to traditional campus-based universities. Whether you choose a traditional four-year college or an alternative program, your information technology coursework will include most of the same materials.

If you want to get a BS degree in computer science, you will need to complete approximately four years of schoolingthe same as for any bachelors degree. There are different types of schools that offer these computer degrees, ranging from online schools to technical schools to traditional campus-based universities. Whether you choose a traditional four-year college or an alternative program, your information technology coursework will include most of the same materials.

When you begin a computer science program, the first semester or two will be spent on the basic introductory courses. This might include computer history, basic terminology, and some other science-related course like calculus and chemistry. This is the point that students often decide which direction they want to take their computer science degree, which could range from programming to networking to computer repair and building. Programming is probably the most popular choice these days, though.

Once you have finished the basic courses and decide on the area you want to specialize in, you can start taking more specific courses. If you want to go into programming, for example, you can start taking fundamental courses in BASIC, FORTRAN and COBOL before more advanced courses on topics such as programming languages like C++ and PASCAL. Or, if you want to go into networking, you will begin taking courses that concentrate on networking systems like Novell and Microsoft Networks.

In most cases, a bachelors degree in computer science or information will involve some sort of final project. The computer and information technology program curriculum may vary from one school to the next, however, and it will also vary greatly depending on the degree you are going after. If you are getting a certificate or an associates degree, you might just focus on one very specific area or get a more basic overview of things. And, if you are getting a masters degree, the learning will be much more in-depth for your specific area of specialization. You can learn more about the program curriculum at various schools by visiting their web sites or speaking to a counselor there.

Millions of people are already using the Law of Attraction to make their lives successful. It’s no longer a secret, but a household term that is rightfully being given the attention it deserves. Anybody can learn how to use the “Law of Attraction” to create whatever one wants in life – be it money, love or happiness – and generate abundance.

Everything that’s coming into your life you are attracting into your life. And it’s attracted by virtue of the images you’re holding in your mind. It’s what you’re thinking. Whatever is going on in your mind you are attracting to you. If you don’t like the results in your life, you need to change your thoughts. That’s ALL that the Law of Attraction is about. But If the Law of Attraction is as simple as that, why arent more people wealthy, even gratified about the state their lives are in?

The Answer is a Simple One. There is an Exact Science to Applying the Law of Attraction to Build the Life You Seek. This Exact Science is called The Science of Getting Rich. The Law of Attraction as explained in “The Secret” movie, and even in much greater detail in The Science of Getting Rich Program, will teach you whatever it is that you may want or need to manifest in your life.

The Science of Getting Rich was first introduced in 1910 when Wallace D. Wattles released his book by the same title that was the inspiration for the film “The Secret”. What is the Science of Getting Rich about? Well in the words of Wallace D. Wattles, “The ownership of money and property comes as a result of doing things in a certain way. Those who do things in this certain way, whether on purpose or accidentally, get rich. Therefore, any man or woman who learns how to do things in this certain way will eventually get rich.” The Secret Science of Getting Rich Seminar is all about teaching you how to do things in this “certain” way to create wealth.

In the Science of Getting Rich seminar – Bob Proctor and Jack Canfield, two of the teachers in the secret, will personally guide you to develop the mind-set of the wealthy. Bob Proctor and Jack Canfield have taken this Science into a Whole New Era. This is What everybody have been Waiting for, Exact Instruction on How To Work with The Law of Attraction! Anybody can now start from today to replace what you don’t want by Attracting what you DO WANT. Here is now a step-by-step instructions showing you how to begin applying the Law of Attraction in your daily life — How to move beyond the theory into action.

Introduction
—————
Forex Robots are automated systems that trade the forex market for you. They are also known as expert advisors (ea’s) and can be referred to as automated trading software.

Advantages
———-
They are useful if you dont have time to trade the currency market on a daily basis. This is referred to as day trading and in some cases scalping. The automated software will can trade for you and make you profit provided you choose a good forex robot. There are reviews all over the net on the different robots available. Forex forums are a good place to look for information. The also reduce the stress day trading can cause and help aspiring traders who have discipline and emotion problems. These can both have a negative affect on trading. Fear and greed are eliminated when automated software trades on your behalf.

Disadvantages
———-
Some people claim that forex robots do not work. Of course not all work but there are a few that can produce profit provided they are used correctly. Factors that have to be considered are: Does the forex robot use a stop loss? You should never use a martingale system as this can blow your account in a single trade. It is also important to choose a broker who has a competitive spread on the pair that the forex robot trades on. Many systems look good in back testing due to slippage, spread and execution delays not being taking into consideration. It is a good idea to forward test the expert advisor before using it on your live account.

What to look for in a forex robot
———–
Make sure that it uses a stop loss. It would be an advantage if it runs on currency pairs with low spreads. Also check the time that the ea is active. Scalping ea’s that run during the quieter times are amongst the most profitbale and have little risk. Even scalping robots can bring big profits with small drawdowns.

Summary
——–
Forex robots do work, it is just a matter of back testing and forward testing untill the system is optimized to bring the highest amount of profit with the smallest amount of risk and drawdown. I use an ea on my live account that I have setup on a virtual private server and it brigns me great results everyday without me having to go through the stress that manual traders do.

Good Luck with your trading!

Quick Science Fair Projects

Students in high school participate in science fairs in order to demonstrate their advanced understanding of a biological or physical sciences concept. These students are required to present a project that indicates higher order thinking and analysis. The standards for evaluating projects for these grade levels can be quite high and the competition can be fierce. The events for young students are based on different principles. Often younger students in the earlier grades participate in quick science fair projects. These quick science fair projects are not based on the level of knowledge or application principles of the high school students projects. The quick science fair projects in the earlier grades are based more on demonstrating an understanding of the facts related to a particular topic of science.

Quick science fair projects for the younger students are often completed in a matter of days, where the high school age students can spend weeks or even months on their projects. The quick science fair projects designed for younger students are tailored for the learning styles and abilities of this age of student. Thinking abstractly is not skills that younger students have developed so quick science fair projects are perfectly suited for their abilities. The characteristics of quick science fair projects include the use of every day items that can be found easily in the home or classroom. The teacher will often provide the necessary materials so that these younger students can experience the successful completion of their quick science fair projects.

While there are processes and the need to record data while completing quick science fair projects, the steps involved will be clearly explained to the students. For the earlier grades it is more important to carefully instruct them throughout the process of completing their projects. Older students can generate some of their own questions and testable theories, but younger students fare better with a set list of materials and how to use those materials to achieve the results. When deciding which quick science fair projects to use in the classroom it is important for these reasons to choose projects that are age appropriate. This way you ensure that the experience of bringing science to life is rewarding and enjoyable for your students.

The two companies, HTC and Microsoft have already worked together on a number of smartphones, including the aesthetically pleasing and powerful HD7.

Running on the Windows Phone 7 operating system, featuring an astonishing touch screen and a 5 mega pixel camera the HTC HD7 is a great handset for people enthusiastic about multimedia and entertainment features.

The 4.3 inch screen offers superb quality at 480 x 800 pixel resolution and with an image display of up to 16 million colours, which are brilliant and clear leading to a sharp and crystal clear picture quality. It is an excellent phone for viewing photos, videos or for gaming. The metal around the camera on the back of the handset can be flipped out to stand the phone up, allowing users to watch videos in full screen landscape mode.

The HTC HD7 operating system’s user interface is effective and powerful, yet simple in concept. The Windows Phone 7 features tile layout of icons with live updates. Thus, the email client icon will show the number of unread messages, while the SMS and phone icons will display the missed calls, voicemails and unread text messages, allowing users an instant overview.

For users to comfortably store their music, video and photo files on the handset, 8 GB internal storage is offered as standard. This amount should be more than enough for most users without requiring extra storage through a micro SD card. The phonebook can accommodate a virtually unlimited number of contacts and also has a photocall feature.

Similarly to the other HTC models, browsing the internet is a pleasure with the HTC HD7.

The camera captures great quality videos at the speed of 30fps, that is unhesitantly a commendable capacity of the lens. One won’t have to get disappointed on the thought of video calling, as this 3G phone is equipped with a secondary camera which lets it capture videos while on the call. When it comes to the music aspects of this device, one cannot question its music producing capabilities as its a walkman phone adorned with the walkman 4.0 player. The additional features of the music player include Shake control, SenseMe and trackID recognition. The shake control allows the users to control the playback just with a shake, give it a shake and the current song will change. This music player can sense the music propensities of the users as it can make play list depending upon the songs stored and played. It separates the songs on the grounds of tempo and mood. Then the trackID music recognition brings the information about the songs, be it about the artists, albums, genres anything else.

The W995 Red ensures that the users do not make any complaint on the data and connectivity speed of the phone. Its brings an enviable speed at web browsing as it is supported by a host of high end technologies. All in all, it is a well balanced gadget.

WhatsApp is one popular mobile messaging in the marketplace today. Some of our carrier providers has included WhatsApp on their promotion supply. I still remember this slogan: “Buy this packet and free WhatsApp in your year”. They selling their SMS rate but giving WhatsApp for free, eventually a . That’s interesting.

I can say getting whatsapp on smartphone is as vital as getting SMS at no cost. The problem isn’t everyone has this app on their phone. And also, i only have this phone, nokia with monophonic ringtone with a monochrome feature. My bad, i have a motto that kinda useless for today : “A phone is meant to be a calling and messaging devices, if you need internet, use a computer – me@2009”. Therefore the point is, i don’t have a smartphone and i’d like WhatsApp.

Look through each entry in the “Command” sections. Note any items that begin with “C:Program Files”. These are really not recommended to start to # 1.You can uncheck any items whose command begins with “C:Program Files”, but may well be some that you want to keep based exactly what program starts logitech computer speakers up. Disable any program you don’t recognize.

That was when Acquired unsolicited but very good advice. I learned that to speed up my computer, I had to uninstall or remove programs are generally unnecessary or unused. If you do not know tips on how to do this, just call at your computer’s cp and make use of the add/remove program you will get in that section. For anybody who is thinking, “My computer is running too slow,” this simple, free task want to do the trick, coupled with cleaning out of the computer’s trash bins. Believe me, many people (I valuable to be one in every of them) care for take their trash bins for granted, not if you know that emptying them is probably one of the easiest ways to increase the speed of a slow computer. Check out your trash bins while keeping them from becoming full or even halfway full to sustain your computer’s good speed.

You can check the temporary files by simply “tools” then “internet options” then “settings” and “view files”. File names too as website names possess been been visited will appear. This will give an idea with the his activity has experienced the net. It also tells you when he last visited the site.

If own not been hiding behind a tree, you probably know generally there are numerous places on net to download movies and videos, such as torrent directories, where you can download one of the most movies straight away to your PC via since.

After you’ve dusted the screen, you will clean it with a damp clothing. Take extra care here to take care that the cloth is only damp, without being wet. Muscular it moist but require not wish to leave water whatsoever on the screen simply because this can damage it.

We all like to think that we are never going to be involved in a crisis or any scenario where risk is running high. Unfortunately for some, their day-to-day jobs involve encountering risk and putting their lives at risk for the good of others.

Very often, working in high risk environments can be difficult, especially if its on foreign soil. Not knowing your surroundings and working with people from different cultures can often be very stressful work. This is where GPS technology can help.

GPS Technology utilises a network of satellites orbiting earth to send and transmit signals back to devices on the ground, at sea and in the air. Satellite technology is ideal for people working in remote locations as it doesnt rely on cell towers and the signal is transmitted directly to the satellite from the device. In certain circumstances, i.e. in a dense forest or built up city area the signal may falter a little but at sea, in the air or on the ground it is usually a very reliable technology and helps teams in situations liaise with central management teams regarding locations, risk and general communication.

The areas of high impact when it comes to Crisis Management technology are places like the 3rd world countries. These countries often span a vast area of expansive land and aid workers travel from village to village trying make sure inhabitants get what they need to survive. Naturally, as people try to do good others will try to hijack this work for their own needs.

This is a perfect example of where Crisis Management technology can help. Not only do the central teams know the exact location of the convoys but they can also advise of, and how to avoid, potential risk situations by using the GPS technology at hand, both by tracking and communicating those on the ground.

With GPS Technology is easy for central teams to deploy backup to the exact location of a situation. It enables teams to be responsive with accurate information, which ultimately saves lives and allows for critical missions to succeed.

The original PHP release was created by Rasmus Lerdorf in June 1995 for his own personal use, to make various common web programming tasks easier and less repetitive and to track the visitors to his online resume.

In 1997, the software transformed from a personal development project into a professional development effort. The name originally stood for “Personal Home Page,” but has since become a recursive acronym, standing for PHP Hypertext Processor.

The goal of this release was to minimize the amount of code required to achieve results, which led to PHP being HTML centric–that is, PHP code was embedded inside HTML.

The second PHP release, known as PHP/F1 2.0 was the first to achieve wide spread popularity, and despite the parsing inconsistencies, it managed to attract a few converts.

The release of PHP 3 was largely driven by Zeev Suraski and Andi Gutmans, who rewrote PHP from the ground up and removed the parsing problems. PHP 3 also made it much easier for others to extend the language. PHP 3 has live up to the design goals of improving the performance of complex applications and modularity of PHP’S code base. Apart from this, it provides end users with a solid infrastructure for lots of different databases, protocols and APIs.

Its successor, PHP 4, contained numerous major changes, including Zend Engine. PHP 4 has introduced multi-threading, which essentially allows particularly lengthy, but non-critical functions to be run independently from the main script process, further streamlining execution.

The engine took over the core of PHP and introduced reference counting, whereby all resources used in scripts (database connections, files, etc) are tracked automatically by the engine, and freed when no longer used to minimize memory usage and ensure there were no memory leaks. In short, Zend engine, take a leading role in improving the performance of PHP scripts.

PHP 5 offers three different types of properties: public, protected and private properties. PHP 5 was released powered by the new Zend Engine II. PHP 5 included new features such as:

Support for object-oriented programming, better support for MYSQL, embedded support for SQlite and integrated SOAP support.
The PHP Data Objects extension, which defines a light weight and consistent interface for accessing databases.
Performance enhancements
Data iterators
Error handling via exceptions

Although not as vast as the jump from PHP 3 to PHP 4, the move from PHP 4 to PHP 5 is still a big one.

Along with hugely improved object orientation, the addition of try/catch error handling, and exceptions, there are two major new extensions: simple XML, a fast and easy-to-learn way to interact with XML documents, and SQLite, a new flat-file database API that eases the burden of deploying simple database solutions.

OLED is a new technology that can make thin, efficient and bright displays. OLEDs are made from organic light-emitting materials, and OLEDs do not require any backlight and filtering systems that are used in LCDs. So OLEDs are more simple to make and actually can be made flexible and transparent as well. OLEDs are also very efficient, and companies are working towards OLED lighting – an OLED “lightbulb” will be efficient and thin, opening the way for great new lighting designs.

There are two types of OLEDs used in displays – PMOLED and AMOLED. The difference is in the driving electronics – it can be either Passive Matrix (PM) or Active Matrix (AM).

With Passive-Matrix OLEDs, the display is controlled by switching on rows and columns. When you turn on row number x and column number y, the pixel at the intersection is lit – and emits light. Each time you can choose just one pixel to light. So you have to turn these on and off very quickly. You do so in a certain sequence, and create the desired image. This is somewhat like the interlace-system used in old CRTs, but the control is done pixel-by-pixel.

PMOLEDs are very easy and cheap to build, but they are limited to small sizes (up to 3″, typically). The image displaying is a bit complicated (because of the row/column method). Also the power consumption is not as good as AMOLEDs.

AMOLEDs have a different driver electronics – each pixel is controlled directly. AMOLEDs are more expensive, and much more difficult to create, but can be used for larger displays (current prototypes are up to 40″) and are very power efficient.

The first OLED products in the market used PMOLEDs – these were MP3 players, sub-displays on cellphones and radio decks for automobiles. The displays were small and usually with just one or two colors. When AMOLED panels started to emerge in 2007 and 2008 we have seen these larger displays in mobile video players, digital cameras, mobile phones main displays and even OLED TVs.

PMOLEDs are still very popular – there are more MP3 player sold today with PMOLED than with LCDs. But for larger displays, AMOLED is the best technology, and is growing much more quickly than PMOLED displays. Obviously for larger displays, such as TV, laptop monitors or PDAs, AMOLED is the only choice.

Today there are several companies that are working on technologies that actually close the gap between PMOLEDs and AMOLEDs – offering a sort of hybrid system. The promise is that these displays will be both easy to make and allow power efficient larger displays. We still have to wait and see whether these technologies actually work on commercial displays. One such technology is Dialog’s SmartXtend.
