DIGITAL DRIVE ARCHITECTURE FOR FLAT PANEL DISPLAYS

摘要

The present invention describes a new digital drive concept for flat panel displays (LCD) where an all-digital drive is used to write data to pixels, which establish the gray scale for each pixel. In addition th einvention integtates the all-digital drive with an optical sensor feedback circuit in the pixel without having to add an extra data line for the pixel sensor. Also discussed is a novel unique puls timing system, where the postioning of the pulse in time has 12 bit accuracy using 8 bit grayscale data and a phase delay system (delay locked loop, DLL).
