Array substrate, liquid crystal panel and manufacturing methods of array substrate and liquid crystal panel

Abstract

The embodiment of the invention discloses an array substrate, a liquid crystal panel and manufacturing methods of the array substrate and the liquid crystal panel, belongs to the technical field of a liquid crystal screen, and solves the technical problem of nonuniform distribution of a voltage inside the liquid crystal panel, which is caused by the fact that an existing liquid crystal panel adopts a plane electrode. The array substrate comprises a common electrode, an insulating layer and a transparent electrode layer; the insulating layer is covered on the common electrode; the position on the insulating layer, which corresponds to the common electrode, is provided with a via hole; the transparent electrode layer is covered on the insulating layer; and the transparent electrode layer is electrically connected with the common electrode in the via hole. The liquid crystal panel comprises the array substrate. The manufacturing method of the array substrate comprises the following steps of: forming the via hole at the position on the insulating layer, which corresponds to the common electrode; and forming the transparent electrode layer on the insulating layer and ensuring that the transparent electrode layer is electrically connected with the common electrode in the via hole. The manufacturing method of the liquid crystal panel comprises the steps in the manufacturing method of the array substrate. The array substrate, the liquid crystal panel and the manufacturing methods of the array substrate and the liquid crystal panel are applied to improvement of the uniformity of the voltage on the common electrode of the liquid crystal panel.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal screens, and in particular relates to an array substrate, a liquid crystal panel and a manufacturing method thereof. Background technique [0002] With the continuous development of electronic technology, liquid crystal displays have been widely used in people's production and life, including televisions, computers, and portable electronic display products. Major panel manufacturers are striving to improve product performance, reduce energy consumption, increase viewing angle, and reduce response time, which is particularly important for the improvement of LCD display afterimages, because it directly affects the quality of the display screen. [0003] Afterimage refers to the phenomenon that after displaying a specific still image for a long time, when it is changed to another image, the trace of the original image remains. Afterimage is a phenomenon that occurs inside the liquid crystal p...

Problems solved by technology

[0005] In the existing liquid crystal panel, the common electrode is arranged in a plane, and the voltage signal is sent through the chip of the data signal, and the common electrode voltage is applied through the wiring around the liquid crystal panel. Because the common electrode arranged in the plane will be different due to the voltage loss during the voltage conduction process Attenuation occurs, so the distribution of the voltage of the common electrode in the entire liquid crystal panel is uneven, resulting in the accumulation of residual charges inside the liquid crystal panel box, generating a DC electric field, affecting the deflection of the liquid crystal molecules in the liquid crystal panel box, and causing afterimages
