中文摘要	A mixed-signal driver chip for a 132 x 64-pixel passive matrix OLED panel is presented. The chip has a 64-step gray scale control using the PWM method and two-step voltage pre-charge technology to pre-charge the OLED pixels. It consists of a digital controller, SRAM for display data memory, a DC-DC voltage converter, reference current generators, a pre-charge voltage generator,64 common drivers, and 132 segment drivers. The single chip is a typical current-drive circuit. It has been implemented in a chartered 0. 35 mu m 18V HV (DDD) CMOS process with a die area of 10mm * 2mm. Test results show that the power consumption of the whole chip and all pixels with a constant driving current of 100 mu A while displaying the highest gray scale is 294mW with a 12V high voltage supply and a 3V low voltage supply.
