An extensible drive system for AM-OLED panel
A drive system for active-matrix OLED panel is presented. The developed system comprises a digital interface which can receive DVI or MCU signals directly, a digital control part, a SRAM for storing display information, common drivers, and the 64-step gray scale segment drivers. Both common driver and segment driver is capable to be cascaded, so it can drive panels in different resolutions by using multiple chips. The drivers are using 0.35um CMOS technology with 15V high voltage devices.
