Liquid crystal display

摘要

A liquid crystal display includes a liquid crystal display panel that is divided into a first display surface and a second display surface including data lines and gate lines, a first data driving circuit configured to drive data lines of the first display surface, a second data driving circuit configured to drive data lines of the second display surface, a gate driving circuit configured to sequentially supply a gate pulse for scanning the first display surface to gate lines of the first display surface and sequentially supply a gate pulse for scanning the second display surface to gate lines of the second display surface, a timing controller configured to divide a unit frame period into a first sub-frame period and a second sub-frame period, a backlight unit configured to provide light to the liquid crystal display panel wherein the backlight unit includes a plurality of light sources, and a light source driving circuit configured to turn off all the plurality of light sources during the first sub-frame period and turn on all the plurality of light sources at a turn-on time within the second sub-frame period.

1. A liquid crystal display comprising:
a liquid crystal display panel that is divided into a first display surface and a second display surface including data lines and gate lines; a first data driving circuit configured to drive data lines of the first display surface; a second data driving circuit configured to drive data lines of the second display surface; a gate driving circuit configured to sequentially supply a gate pulse for scanning the first display surface to gate lines of the first display surface and sequentially supply a gate pulse for scanning the second display surface to gate lines of the second display surface; a timing controller configured to divide a unit frame period into a first sub-frame period and a second sub-frame period, and configured to copy an input data to generate a copied data; a backlight unit configured to provide light to the liquid crystal display panel wherein the backlight unit includes a plurality of light sources; and a light source driving circuit configured to turn off simultaneously all the plurality of light sources during the first sub-frame period and turn on simultaneously all the plurality of light sources at a turn-on time within the second sub-frame period, wherein the input data is displayed on the first and second display surfaces during the first sub-frame period, and the copied data equal to the input data is displayed on the first and second display surfaces during the second sub-frame period, wherein the turn-on time of all the plurality of light sources is set based on one of saturation time of liquid crystals in a middle portion of the first display surface and saturation time of liquid crystals in a middle portion of the second display surface, and wherein the timing controller synchronizes the input data and the copied data with a frame frequency of (unit frame frequency)×N to repeatedly display the input data and the copied data on the liquid crystal display panel during the first and second sub-frame periods for reducing a difference between the turn-on time of the light sources and the saturation time of the liquid crystals, where N is a positive integer equal to or greater than 2.
