TFT-LCD driver circuit and LCD devices

摘要

Thin Film Transistor-Liquid Crystal Display (TFT-LCD) driver circuit having a source drive buffer with an operational amplifier having two differential amplifiers operating alternatively according to timing signals and bias voltage signals is disclosed. The differential amplifiers are further capable of functioning as a voltage follower by buffering and outputting voltage signals from a Digital to Analog Converter for charging display points. The TFT-LCD driver circuit may also be incorporated within an LCD device.
