| 摘 要： | 本文介绍一种用于实现被动有机发光二极管矩阵(PM-OLED)高灰度显示的混合驱动方法.该方法基于电流型数模转换器和时空数字调制方法的混合驱动来实现整体屏幕的显示驱动.在该方法中,显示数据的低灰度权值由数模转换器完成调制,同时显示数据的高灰度权值由时空数字调制方法进行调制.该方法应用于128×128彩色PM-OLED可以驱动512级灰度显示.

| Abstract: | Amix control driving method of passive matrix OLED(PM2OLED) is described to drive high gray scale display. The method is based on mix control of current digital to analog converter(DAC) and digital space time modulation (DSTM). The low bit gray scale is driven by the DAC while the high bitgray scale is generated by DSTM. This method is applied to a 128×128 dots RGB PM2OLED panel which can drive 512 gray scales. |
