<p>PURPOSE: A circuit and a method for driving signals of a liquid crystal display are provided to minimize flickering and image sticking of the liquid crystal display. CONSTITUTION: A circuit for driving signals of a liquid crystal display includes a column driver(3), a gamma voltage circuit(4), and an external voltage supply(500). The column driver converts video data to an analog signal and applies the analog signal to pixel electrodes of a liquid crystal display panel(6). The gamma voltage circuit applies a plurality of signal voltages for converting the video data to the analog signal to the column driver. The external voltage supply generates the signal voltages and a common voltage supplied to a common electrode(52), and applies the signal voltages and common voltage to the gamma voltage circuit and the common electrode.</p> |
