Problems solved by technology

[0003] In order to prevent the polarization of the liquid crystal, the current panel drive adopts the AC drive method, but this method often causes insufficient charging of the pixels, resulting in a dark display. In order to improve the insufficient charging, we use voltage compensation to ensure the normal display screen

Abstract

The invention discloses an over-voltage compensation method of a display panel, a display panel and a display device. The over-voltage compensation method comprises the steps of after a final scanningline of a current frame is scanned and before starting of a first scanning line of a next frame, transmitting a preset voltage signal to an in-plane data line; in transmitting the preset voltage signal to the in-plane data line, keeping all scanning lines in a closed state, after scanning the final scanning line of the current frame, in an idle time period before starting the first scanning lineof a next frame, keeping all scanning lines in a closed state, and transmitting the preset voltage signal to the in-plane data line in the idle time period for changing the inner voltage. The over-voltage compensation method, the display panel and the display device can improve an overvoltage problem between the last line of the current frame and the first line of the next frame, particularly a problem of insufficient charging caused by over-voltage switching between different polarities.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel cross-voltage compensation method, a display panel and a display device. Background technique [0002] With the development and progress of science and technology, flat panel displays have become the mainstream products of displays due to their thin body, power saving and low radiation, and have been widely used. The flat panel display includes a Thin Film Transistor-Liquid Crystal Display (TFT-LCD) and an Organic Light-Emitting Diode (OLED) display. Among them, the thin film transistor liquid crystal display controls the rotation direction of the liquid crystal molecules to refract the light from the backlight module to produce a picture, and has many advantages such as thin body, power saving, and no radiation. The organic light-emitting diode display is made of organic light-emitting diodes, which has many advantages such as self-luminescence, short response ...
