Embodiment Construction

[0046] When the average value of the original pixel voltage corresponding to the original pixel data (that is, the target grayscale value of each pixel originally intended to be displayed) of all pixels in two adjacent pixel columns is not the same, the liquid crystal display of the embodiment of the present invention The original pixel data of each pixel on the pixel column will be adjusted to compensate for the offset of the common voltage level caused by the crosstalk phenomenon. In this way, the liquid crystal display of the embodiment of the present invention has the effect of suppressing the crosstalk phenomenon.

[0047] image 3 A block diagram of a liquid crystal display according to an embodiment of the present invention is shown. The liquid crystal display 300 includes a timing control circuit 310, a data driver 320, a scan driver 330, a liquid crystal display panel 340, data lines 351 and 352, and scan lines 361 and 362. The liquid crystal display panel 340 includes p...

Abstract

The invention relates to a liquid crystal display and a drive method thereof. The liquid crystal display comprises a liquid crystal display panel, a scanning driver, a time sequence control circuit and a data driver, wherein the liquid crystal display panel comprises a first pixel row and a second pixel row. The time sequence control circuit determines a modification voltage index value accordingto the absolute value of the subtraction difference of the average value of original pixel voltage corresponding to the original pixel data of all the pixels of the first pixel row and the average value of original pixel voltage corresponding to the original pixel data of all pixels on the second pixel row; modification voltage is determined according to the modification voltage index value; the regulation pixel voltage of target pixels is determined according to the original pixel voltage of the target pixels on the second pixel row and the modification voltage; and regulation pixel data corresponding to the regulation pixel voltage are output. The data driver outputs the regulation pixel voltage to the target pixels according to the regulation pixel data.

Description

Technical field [0001] The present invention relates to a liquid crystal display and a driving method thereof, and in particular to a liquid crystal display having a cross talk suppression function and a driving method thereof. Background technique [0002] In the field of liquid crystal display technology, crosstalk has always been a difficult problem to solve. Figure 1A Shows an example of the image that a conventional liquid crystal display needs to display. Figure 1B versus Figure 1C Respectively show Figure 1A The display grayscale values ​​of some pixels in the area 10 and area 20. Figure 1D Shows the actual image displayed on a conventional LCD display. When you want to make the traditional LCD display Figure 1A In the image, due to the crosstalk phenomenon, the traditional liquid crystal display produces such Figure 1D Of the image. [0003] figure 2 A circuit diagram of one pixel of the liquid crystal display is shown. figure 2 Here, the pixel includes a transi...
