Liquid crystal display having different common voltages

摘要

Disclosed is a liquid crystal display that prevents a flicker by employing a circuit with adjustable resistors in the output of a common voltage generator. The common voltage generator supplies two distinct common voltages, one common voltage being supplied to a common electrode at a point that is physically close to the output of a gate driver, and a second common voltage being supplied to a point that is physically further from the output of the gate driver than the point where the first voltage is applied. These points where the first common voltage and the second common voltages are applied are electrically coupled via an internal panel resistor. A flicker is prevented by adjusting the variable resistors so that the difference between the first and second common voltages is equal to the difference in the kickback voltages at the first point and at the second point.
