What is OLED (emitting diode emitting organic light)?
OLED (Organic Light Emituting Diode) consists of an emission organic material that, when supplied with electric shock, can create an excellent full -color flat panel. The most visible difference is that OLED is so thin that it can even be placed on a plastic movie! This makes it much lighter than older technologies and a great advantage for manual devices, laptops and laptops. The door to the flexible display even opens. OLED is also clearer and has a better contrast than LCD, but does not require backlight. It consumes about 20% less energy than LCD and has the response time every piece as fast as CRT is displayed. Add to this favorable list that OLED displays can be clearly displayed at almost any angle - by 170 degrees. As if that is not enough, they boast exceptional clarity and refresh at speeds 3 times faster than necessary for standard video applications!
The OLED display consists of thin sandwich layers of materials. When electric current is supplied, negatively charged electrons in the cathode layer move organic substances towards a positively charged anode layer. The opposite occurs from the anode because the positively charged electrons are attracted to the cathode and leave the holes in the conductive material. These positive openings jump on organic material to recomb with electrons, causing electrolyuminescent light. The chemical composition of the organic material dictates which light colors are created.
Eastman Kodak has invented OLED technology in the early 80s. It has been improving it since then with other companies. Sanyo Electric and Eastman Kodak United for the common company SK Display so that the first OLED be commercially available in digital still camera introduced in 2003, The EasyShare LS633.
Another breakthrough appeared in October 2004, when Auo Technology Center announced the very first double -sided Active nut OLED. This display can display two separate images on one panel, moving or still using the front and rear of the panel. This is ideal for applications such as flip-taons that have external and internal screens.
virtually every product that uses LCD or CRT technology is a candidate for OLED, including gaming devices, mobile phones, camcorders, DVD players, GPS, audio displays, PDA, notebooks, monitors and TV. With low energy consumption, virtual weightlessness, cleanliness, brightness and extensive viewing angle, OLED is a new generation display technology.
