A 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, since the common electrode is divided into a plurality of sub-common electrodes arranged side by side along the extending direction of the grid line, the current liquid crystal display panel is different from the existing liquid crystal display panel. In contrast, different common electrode signals can be applied to each sub-common electrode. In the above-mentioned liquid crystal display panel provided by the embodiment of the present invention, the voltage value of the common electrode signal applied to each sub-common electrode follows the voltage value of the gate signal on the gate line. The transmission direction is gradually increasing, therefore, the voltage on the sub-common electrode can compensate the inconsistency of the voltage deviation ΔVP of each pixel electrode in the entire liquid crystal display panel caused by the delay of the resistance and capacitance, thereby eliminating the inconsistency caused by the inconsistency of ΔVP Problems such as flickering of the screen caused by the problem, and then improve the picture quality of the liquid crystal display panel.

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
