摘要： A liquid crystal panel driving apparatus is adapted to display a uniform level of luminance on an entire display area of a liquid crystal panel. The liquid crystal panel drive apparatus applies an alternative current signal to a storage line on the liquid crystal panel so that the signal voltage charged at each picture element on the first gate line is substantially equal to the signal voltage charged at each picture element on the second to last gate lines. As a result, the luminance level on a first line of the liquid crystal panel is substantially equal to that on the remaining lines and the luminance level is uniformly displayed on the liquid crystal panel, and further enhances the quality of a picture displayed on the liquid crystal panel.
