Problems solved by technology

[0003] At present, a dual-common-electrode solution has been proposed, that is, by separately adjusting the voltages of the common electrodes of the liquid crystal capacitor and the common electrode of the storage capacitor to ensure a fixed voltage difference, but the accuracy of the voltage difference obtained by this control method Not high, and complicated to control

Abstract

The invention relates to a common voltage generating circuit and a display panel. The common voltage generation circuit includes: a first output module, used to set the data of the first common voltage and output the first common voltage; a second output module, used to set the data according to the first common voltage and the preset voltage difference output the second common voltage. The application effectively solves the problem that the conventional common voltage generation circuit separately adjusts the two common voltages to maintain a fixed difference between the two common voltages, resulting in complicated control.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a common circuit generation circuit and a display panel. Background technique [0002] Usually, a liquid crystal display panel includes a liquid crystal capacitor and a storage capacitor. The common electrode of the liquid crystal capacitor and the common electrode of the storage capacitor are connected to a common voltage generating circuit. Different angles of deflection make the transmitted light different, thus producing different gray scales and realizing the display of the desired screen; the common voltage received by the storage capacitor is to charge the storage capacitor to prevent the voltage of the liquid crystal capacitor from failing when the screen data is updated next time. To meet the required screen display voltage, therefore, the common voltage of the common electrode of the liquid crystal capacitor and the common electrode of the storage capacitor needs to ma...
