  • TFT-LCD DRIVER CIRCUIT AND LCD DEVICES
    Publication number: 20090167747
    Abstract: Thin film transistor liquid crystal display (TFT-LCD) driver circuit having a source drive buffer with an operational power amplifier having two differential amplifiers capable of alternating operation according to timing and bias voltage signals. The differential amplifiers are further capable of functioning as a voltage follower by inputting and outputting voltage signals from a digital to analog converter for charging display points. The TFT-LCD driver circuit may also be incorporated within a LCD device.
