Liquid crystal display panel and display device

Abstract

The invention discloses a liquid crystal display panel and a display device. In the liquid crystal display panel, a public electrode is divided into multiple sub public electrodes which are arranged side by side in the extending direction of a grid line, and as a result, compared with an existing liquid crystal display panel, the liquid crystal display panel has the advantage that different public electrode signals can be applied to all the sub public electrodes. According to the liquid crystal display panel, the voltage of each public electrode signal applied to the corresponding sub public electrode becomes larger gradually in the transmission direction of a grid signal on the grid line, as a result, the problem of inconsistency of the voltage deviation delta VP of all pixel electrodes of the whole liquid crystal display panel due to delay of resistance and capacitance is solved through compensation of the voltage of the sub public electrodes, the problems such as image flicker caused by the inconsistency of the voltage deviation delta VP are eliminated, and the image quality of the liquid crystal display panel is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a display device. Background technique [0002] In recent years, liquid crystal display panels (Liquid Crystal Display, LCD) have gradually spread in people's lives. A liquid crystal display panel is mainly composed of an array substrate, a color filter substrate, and liquid crystal molecules located between the two substrates. The liquid crystal display panel controls the orientation of liquid crystal molecules through an electric field to change the transmittance of the liquid crystal display panel, thereby realizing the display function. In the liquid crystal display panel, the electric field controlling the liquid crystal molecules is determined by the voltage difference between the pixel electrode and the common electrode, but due to the existence of parasitic capacitance, the voltage of the pixel electrode will jump when th...

AI Technical Summary

Problems solved by technology

In the liquid crystal display panel, the electric field controlling the liquid crystal molecules is determined by the voltage difference between the pixel electrode and the common electrode, but due to the existence of parasitic capacitance, the voltage of the pixel electrode will jump when the gate signal is turned off. ΔV P In order to ensure the display quality of the liquid crystal display panel, the voltage deviation ΔV of the voltage of all pixel electrodes before and after the jump occurs P should be consistent

[0003] However, in the liquid crystal display panel, due to the delay of the resistance and capacitance, the gate signal transmitted on one gate line will be distorted along the transmission direction, which will cause the voltage of the pixel electrode to change along the transmission direction of the gate signal on the gate line. delay, and generally the voltage applied to the common electrode is uniform, resulting in a voltage deviation ΔV of each pixel electrode in the entire liquid crystal display panel P Inconsistency, the LCD panel will cause problems such as screen flickering, which is more obvious in large-size LCDs
