Display panel data voltage control method, display panel and display equipment

Abstract

The invention discloses a display panel data voltage control method, a display panel and display equipment, which relate to the technical field of display. The display panel data voltage control method comprises the steps of: determining whether gray-scale mutation occurs on the same data line, wherein the gray-scale mutation indicates that a gray-scale variation value between two adjacent pixel units on the same data line is greater than a preset threshold value; and controlling corresponding data voltage to increase or decrease when a scanning line scans a gray-scale mutation position if thegray-scale mutation occurs. By adopting the display panel data voltage control method, the horizontal crosstalk can be reduce or eliminates, and the panel display quality can be improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for controlling data voltage of a display panel, a display panel and a display device. Background technique [0002] In a Thin Film Transistor Liquid Crystal Display (TFT-LCD), a part of the area on the display screen will be affected by another part of the area to distort the picture and generate crosstalk. Specifically, a coupling capacitance is formed between the data line and the common electrode. When the voltage signal of the data line changes, the signal voltage of the common electrode will also be affected and changed, and the coupling will increase, so that the pixel cannot be charged to the correct potential, resulting in crosstalk. Phenomenon. In the long-term research and development process, the inventor of the present application found that with the increase of the size of the liquid crystal display panel, the capacitive load is also increas...

Problems solved by technology

Specifically, a coupling capacitance is formed between the data line and the common electrode. When the voltage signal of the data line changes, the signal voltage of the common electrode will also be affected and changed, and the coupling will increase, so that the pixel cannot be charged to the correct potential, resulting in crosstalk. Phenomenon

In the long-term research and development process, the inventor of the present application found that with the increase of the size of the liquid crystal display panel, the capacitive load is also increasing, and the capacitive coupling is more serious, especially the coupling of the data line to the reference potential signal on the side of the color filter substrate , making horizontal crosstalk serious
