Abstract

A high data accuracy and low power consumption driving method and output stage of the source driver are proposed for the LTPS TFT-LCD in mobile applications. The proposed driving method is insensitive to the variations of the electrical characteristics of TFTs, which enables the output errors of the source driver are under 1/2 LSB in all gray levels. In addition, the power consumption of the driver with the method is decreased to 9.9mW which is 55.9% of that of the conventional source driver by reducing unnecessary charge waste.
