Method for regulating common voltage, regulating device and display device

Abstract(summary):

A method for regulating a common voltage, a regulating device and a display device. It relates to the display field, which ensures the flicker in the center region of the display panel being relative small meanwhile improving the flicker situation of the edge region of the display panel, thereby improve the flicker uniformity of the display panel. The present disclosure provides a method for regulating a common voltage including: arranging sampling points which at least include: sampling points arranged in the center region of the display panel and sampling points arranged in the edge region of the display panel; optimizing the common voltage value written into the driving chip, such that the flicker values of the sampling points located in the display panel are less than or equal to a first threshold when the common voltage value is applied to the display panel for display.
