Patent ID: 7893900

Claim:
A liquid crystal display device, comprising: a liquid crystal panel comprises a plurality of pixels, a plurality of common lines along a first direction, a plurality of gate lines, where the plurality of common lines are supplied with a common voltage, wherein the plurality of pixels are driven according to a first pattern or a second pattern; a gate driver connected to the liquid crystal panel through a tape carrier package to supply gate voltages to the plurality of gate lines; at least one common voltage supply line in at least one of the gate driver and the tape carrier package and connected to the plurality of common lines; a first region, and a plurality of second regions and third regions, each of the plurality of second and third regions comprising vertical multiple color lines, and wherein the first region is configured to have a voltage level with an amplitude that is between a voltage level amplitude of the second region and a voltage level amplitude of the third region, the plurality of second and third regions alternately arranged; and a driving circuit configured to measure a common voltage of the liquid crystal panel and generate a data driving signal that changes the driving pattern to one of the first pattern or second pattern in response to the measured common voltage.
