摘要
2.4-in. organic light emitting diode panel with blue monochrome emission and resolution of 160 x 160 has been fabricated by using vacuum evaporation. It has the device structure of ITO/CuPc/NPD/DPVBi/Alq3/LiF/Al:Li(0.1 wt%) as of anode/hole injection layer/hole transport layer/emitting layer/electron transport layer/hole blocking layer/cathode respectively, and total thickness of organic layers besides anode and cathode electrode is 131 nm. Conventional photolithographic process was applied for patterning ITO., insulator and cathode separator and open aperture ratio of each pixel is 64.4%. Driving module selected the PWM method to embody the color depth of 16 gradations with the electric current control and it introduced a dual scan method that considered the panel brightness increase and device stability.
