Study and AISC design of a high efficiency OLED scan controller

As a novel display material, OLED attracts more and more attention in recent years. This paper researches on the OLED scanning control circuit, and puts forward a novel adjustable grayscale scan method which adopts random weight algorithm after studying different scan schemes. Considering the efficiency of scan buffer unit, a dual radix interleaving clock architecture is proposed in the paper, and the ASIC design of scanning control chip is also carried out. The experimented result convinces that the efficiency of the novel scan circuit is enhanced approximately 50%. Meanwhile, the innovational gray control method for FPD with independent intellectual property rights is also obtained.
