Character LCD Modules OLED concepts and overview

OLED, the organic light emitting diode (OrganicLight-EmittingDiode), also known as laser electroluminescent display (OrganicELectroluminesenceDisplay, OELD). Because with light, power-saving features, so starting in 2003, this display device in the MP3 player has been widely used, and for digital products belong to the DC with the phone, had just been used to show off some of OLED Engineering samples of the screen, but not into the practical application stage. But they have a lot of Oled screen LCD incomparable advantages, it also has been favored by the industry.OLED Display Module
OLED display technology with traditional LCD displays in different ways, no backlight, with a very thin coating of organic material and the glass substrate, when a current is passed, these organic materials will be light. And OLED display can be made thinner and lighter, larger viewing angle, and can significantly save energy.
Currently the second largest in the OLED technology system, low molecular OLED technology for the Japanese master, while the so-called polymer PLEDLG OEL is this phone system, technology and patents by technology companies in the UK CDT grasp, both compared to PLED products Colorize there are still difficulties. The low molecular OLED is easier colorization, recently Samsung has released a 65,530-color phone with OLED.TFT Lcd Modules
However, although better future technologies such as TFT OLED will replace LCD, but the organic light-emitting display technology, there are still short life, large-scale screen is difficult and other defects. OLED is currently used primarily as a new listing of the Samsung SCH-X339 on the use of 256-color OLED, as OEL is mainly used in its CU81808280 LG, we have seen.
In order to illustrate the image of OLED structure, each OLED element can be likened to a hamburger, the luminescent material is caught in the middle of the vegetables. Each OLED display unit can be controlled to produce three different colors of light. OLED and LCD, as there are active and passive of the points. Passive mode selected from the ranks of the address unit is lit. Active mode, OLED element is followed by a thin film transistor (TFT), TFT drive the light emitting unit lights. Proactive OLED more power, but the passive OLED display better performance.
