OLED TFT Display Module structure and luminescence mechanism brief

The OLED display device is based on a current-type semiconductor light emitting device of an organic material. Its typical structure is produced on the ITO glass tens of nanometers thick layer of an organic light emitting material for the light emitting layer, the light emitting layer above the layer of a low work function metal electrode. When the electrode voltage, the light emitting layer to generate light radiation.TFT LCD Misplays
OLED light-emitting mechanism and process from the yin and yang poles were injected electrons and holes injected electrons and holes in the organic layer transmission, and in the light-emitting layer composite, so as to stimulate light-emitting layer molecules to produce single-exciton single-exciton radiative decay and light.

OLED To get full-color There are three ways:
1, using white light-emitting layer plus color filter. This is the easiest way to obtain a full color display.
2, using red, green, and blue organic light emitting material, the light-emitting layer is a three-layer structure.
3, the use of blue organic light-emitting materials, full color and then the color conversion material.lcd graphic display
