Technology has changed our lives in ways we only imagined in our dreams. Imagine a flexible, high-quality display that's simple and affordable. Television or computer screens as big as a wall, but only as thin as a sheet of plastic. With such bright and vibrant colors you'll feel like you're in the thick of the action, whether you're watching your favorite movie or playing your favorite computer game. That seems very unlikely with today's bulky, heavy, power-hungry cathode ray tubes, often referred to as CRTs. They are in our televisions and computers emitting radiation and eating away at our hard-earned money. They have become so plentiful and easy to produce that you can get a decent-sized computer monitor for under $100. We've tried these sleek and stylish LCD and plasma screens, but when you look at one you see something is missing. Something you would only see in a nice bright and clear CRT display. LCDs have improved greatly since their first appearance in the large display area, but there is still much to be done. Plasmas are also great, but they are very complex and expensive. They suffer from poor brightness and image quality (zdnet.com). There is technology being developed in research labs around the world that could change all this (Ibm.com). It's called an OLED display and it could really change the way we look at technology. OLED stands for Organic Light Educing Diode, they are sometimes referred to as organic light-emitting devices. OLEDs are made of an organic material with luminescent properties that lights up when voltage passes through it. They work on the principle of converting electrical energy into light, a phenomenon known as electroluminescence. The basic structure of a single OLED consists of an organic material or a combination of organic materials between metal electrodes on a glass plate. At least one of the metals must be transparent in order to observe the light emitted. Indium tin oxide is a conductive and transparent metallic substance; the other metal can be reflective or even transparent depending on the intended use of the display. The electrodes are then connected to a voltage source. When current is supplied the atoms of the organic material react with the electrical energy and emit energy in the form of light which may have a shade depending on the organic material used.
