Abstract

A low power and small area source driver using LTPS TFTs is proposed for mobile applications. This source driver adopts level shifter with holding latch function and new R-to-R type digital-to-analog converter (DAC). The power consumption and layout area of the proposed source driver are reduced by 23% and 25% for 16M colors and qVGA AM-OLED panel, respectively.
