Problems solved by technology
This is because any one of the positive and negative polarities of the data voltage charged in the liquid crystal cell becomes the main polarity according to the data voltage charged in the liquid crystal cell, and there is a lack of balance between the positive and negative polarities, thus applying The common voltage to the common electrode produces an offset

A liquid crystal display is provided. The liquid crystal display includes a liquid crystal display panel, a data driving circuit for converting digital video data into positive / negative data voltages to be supplied to the data lines and adjusting the horizontal polarity inversion cycle of the positive / negative data voltages, and a timing controller for generating the vertical polarity control signal and the horizontal polarity control signal, adding a FRC correction value to input digital video data to supply the input digital video data to the data driving circuit, detecting a predetermined weak pattern from the input digital video data and, when data having the weak pattern is detected, changing either the logic inversion cycle of the vertical polarity control signal or the logic of thehorizontal polarity control signal and changing the position of the data to which the FRC correction value is added.
Description
[0001] This application claims the benefit of Korean Patent Application No. 10-2008-128823 filed on December 17, 2008, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0002] The present invention relates to a liquid crystal display (LCD). Background technique [0003] Active matrix driven liquid crystal displays display moving images by using thin film transistors (TFTs) as switching elements. Since such LCDs can be made smaller than cathode ray tubes, such LCDs are rapidly replacing cathode ray tubes in displays of televisions, mobile information devices, office computers, computers, and the like. [0004] A liquid crystal cell of a liquid crystal display displays graphic images by changing transmittance according to a potential difference between a data voltage supplied to a pixel electrode and a common voltage supplied to a common electrode. Liquid crystal displays are generally driven with an inversion mechanism...
