Abstract

The invention relates to display device. The display device comprises a display panel with a plurality of display units, a data driving circuit and a common voltage circuit, wherein the display units comprise pixel electrodes and common electrodes; the data driving circuit is used for supplying display gray scale voltage corresponding to display data to the display units; the pixel electrodes are matched with the common electrodes to display the display data; the display panel further comprises a switch circuit for connecting the multiple display units to the data driving circuit; the switch circuit transmits the display gray scale voltage from the data driving circuit to the pixel electrodes in the displaying period and feeds gray scale voltage of the pixel electrodes back to the data driving circuit in the feedback period; the data driving circuit correspondingly outputs a feedback signal to the common voltage circuit according to the fed back gray scale voltage and adjusts common voltage.

Description

technical field [0001] The present invention relates to a display device, in particular to a display device capable of adjusting its common voltage. Background technique [0002] In the prior art, a liquid crystal display device includes a pixel electrode and a common electrode. The pixel electrode is applied with a grayscale voltage corresponding to the image data to be displayed in real time. The common electrode is applied with a common voltage of a fixed potential. Between the grayscale voltage and the common electrode Driven by the voltage, the pixel electrode cooperates with the common electrode to generate an electric field, thereby driving the liquid crystal molecules to deflect and display images. [0003] Since the liquid crystal molecules are fixed in an electric field with a voltage difference for a long time for deflection, the rotation characteristics of the liquid crystal molecules will be destroyed, and they can no longer rotate by a corresponding angle due t...
