Abstract :
The paper first argues the system level design of the OLED drive chip. After analyzing the feature of OLED and the display panel (Sempel and Buchel, 2002), it presents how to eliminate the cross talk effect by the precharge circuit, and compares the drive efficiency between two precharge schemes. Then the dual radix interleaving clock architecture is proposed to enhance the lighting efficiency and dynamic feature of the OLED display panel. The circuit is realized by the dual state machine locks. At last the article demonstrates the effect on the efficiency of both display and transmission between the three RAM management architecture enables the OLED drive chip adapt to different gray scales
