  • Active matrix liquid crystal display and driving method thereof
    Patent number: 7834837
    Abstract: An exemplary active matrix LCD (200) includes an LCD panel, a gate driver (211), a data driver (212), and a voltage compensating circuit (240). The LCD panel includes a plurality of gate lines (221) and a plurality of data lines (222) crossing the data lines to define a plurality of pixel units (230). Each pixel unit includes a liquid crystal capacitor (227) and a TFT (223). The liquid crystal capacitor includes a pixel electrode (224) and a common electrode (225). The voltage compensating circuit is configured for detecting a first voltage of a source electrode of one of the TFTs when the TFT turns on, detecting a second voltage of a drain electrode of the TFT when the TFT turns off, and then outputting a compensating voltage according to the first voltage and the second voltage for compensating a kick-back voltage of the TFT.
