- LIQUID CRYSTAL DISPLAY PANEL DRIVER WITH REDUCED CROSS-TALK

摘要

The present invention relates to a liquid crystal display panel driver, wherein the liquid crystal display panel driver inverts and outputs a phase of a common output signal and a segment output signal each frame and at a predetermined period within one frame. Therefore, it is possible to prevent the liquid crystal constituting each pixel of the LCD panel 30 from being deteriorated by a direct current (DC) electric field. Furthermore, a cross-talk phenomenon is prevented in which unselected cells around the selected cell are affected when the selected cell among the pixels is turned on / off in response to the common output signals and the segment output signals. can do.
