The OLED TFT Display Modules principle, technical characteristics

OLED, i.e., the organic light emitting diode (Organic Light-Emitting Diode), also known as organic laser display (the Organic Electroluminesence Display OELD). OLED screen with thin, power-saving features, but has the incomparable advantage of many LCD.
The principle of OLED
The OLED refers to an organic semiconductor material and a light emitting material emitting phenomenon in the electric field is driven by the carrier injection and composite. Its principle is based on the ITO transparent electrode and a metal electrode as the anode and the cathode of the device, in the constant voltage drive, the electrons and holes injected from the cathode and the anode, respectively, to the electron and hole transport layer, electrons and holes, respectively, through the electronic and The hole-transporting layer to migrate to the light emitting layer, and meet in the light emitting layer to form excitons and the light emitting molecule, which emits visible light through radiative relaxation. The radiated light can be observed from the ITO side, and a metal electrode film also played the role of the reflective layer. Made according to the principles of such a light emitting display is referred to as an organic light emitting display, also called an OLED display.8x2 lcd display
The technical characteristics of the OLED
Compared with LCD, OLED is self-luminous, wide viewing angle;, light weight, small thickness; high brightness, high luminous efficiency; luminescent materials, easy color display; fast response, high dynamic picture quality; wide temperature range; soft; process is simple, low cost; seismic capability, a series of advantages, so it is considered by experts known as the ideal display.serial oled
