Full dynamic resolution low lower DA-Converters for flat panel displays

[摘要] It has been shown that stepwise charging can reduce the power dissipated inthe source drivers of a flat panel display. However the solution presentedonly provided a dynamic resolution of 3 bits which is not sufficient forobtaining a full color resolution display. In this work a further developmentof the basic idea is presented. The stepwise charging is increased to 4 bitsand supplemented by a current source to provide an output signal whichrepresents an 8 bit value with sufficient accuracy.Within this work theapplication is an AM-OLED flat panel display, but the concept can easily beapplied to other display technologies like TFT-LCD as well.
