LIQUID CRYSTAL DISPLAY AND DRIVING METHOD THEREOF

摘要

A liquid crystal display includes: a display panel; a signal controller configured to receive an input image signal and an input control signal, output an output image signal and an output control signal, and determine a charge sharing between two or more data lines having voltages in the same polarity; and a data driver configured to convert, based on the output control signal, the image signal into data voltages to be supplied to the data lines connected to the pixels, the data voltages having positive levels and negative levels. The data driver is further configured to perform a first charge sharing by short-circuiting first and second data lines that are adjacent to each other, and a second charge sharing by short-circuiting third and fourth data lines having data voltages in the same polarity, wherein the first charge sharing and the second charge sharing may not temporally overlap with each other.

1. A liquid crystal display, comprising:
a display panel comprising a plurality of pixels and a plurality of data lines connected to the plurality of pixels; a signal controller configured to receive an input image signal and an input control signal and output an output image signal and an output control signal, the signal controller further configured to determine a charge sharing between two or more data lines having voltages in the same polarity; and a data driver configured to:
convert, based on the output control signal, the image signal into data voltages to be supplied to the plurality of data lines connected to the plurality of pixels, the data voltages having a plurality of positive levels and a plurality of negative levels;perform a first charge sharing by short-circuiting first and second data lines that are adjacent to each other, the first data line having a positive voltage and the second data line having a negative voltage in a first time frame and the first data line having a negative voltage and the second data line having a positive voltage in a second time frame subsequent to the first time frame; andperform a second charge sharing by short-circuiting third and fourth data lines having data voltages in the same polarity, when determined that the third data line has a first voltage level of a particular polarity in a first sub-period and the third data line has a second voltage level of the particular polarity a second sub-period subsequent to the first time period, wherein the first charge sharing and the second charge sharing do not temporally overlap with each other.
