Abstract:
1. A liquid crystal display device including a liquid crystal display panel provided with thin film transistors comprising: a timing controller having an input terminal for receiving control signals transmitted from a host system, wherein the timing controller further includes an output terminal; a frequency detector connected to the input terminal or the output terminal of the timing controller to detect the transmitted control signals; compensation voltage setting means connected to an output terminal of the frequency detector, wherein the compensation voltage setting means receives the control signals detected by the frequency detector and generates a compensation voltage control signal based on the detected control signals; and a voltage converter connected to an output terminal of the compensation voltage setting means and to the liquid crystal display panel, the voltage converter generating a compensation voltage based on the compensation voltage control signal and a driving voltage output by the host system so as to adjust a charge time of the thin film transistors and delivering the compensation voltage to the liquid crystal display panel.
