Abstract

The invention relates to a liquid crystal display and a public voltage regulating method. The liquid crystal display comprises an LCD panel, a scan driver circuit, a data driver circuit and a control circuit. The LCD panel comprises a plurality of mutually parallel scanning lines, a plurality of mutually parallel data lines which intersect with the scanning lines in an insulated way, a plurality of thin-film transistors which are arranged between the intersection of the scanning lines and the data lines, a plurality of pixel electrodes and a plurality of public electrodes which are opposite to the pixel electrodes. The scan driver circuit is used for providing scanning signals for the scanning lines and the data driver circuit is used for providing grey scale voltage for the data lines; and the control circuit is used for regulating the voltage of the public electrodes according to image signals.

Description

technical field [0001] The invention relates to a liquid crystal display and a common voltage adjustment method thereof. Background technique [0002] see figure 1 , is a schematic diagram of a prior art liquid crystal display. The liquid crystal display 10 includes a liquid crystal display panel 101 , a scanning driving circuit 11 , a data driving circuit 12 and a backlight module (not shown). [0003] The liquid crystal display panel 101 includes a plurality of scanning lines 13 parallel to each other, a plurality of data lines 14 parallel to each other and insulated from and intersecting with the scanning lines 13 , and a plurality of thin film transistors 15 located at intersections of the scanning lines 13 and the data lines 14 , a plurality of pixel electrodes 151 and a plurality of common electrodes 152 opposite to the plurality of pixel electrodes. The smallest area defined by the scan line 13 and the data line 14 defines a sub-pixel 16 , and the sub-pixels in eac...
