Problems solved by technology

However, due to the influence of the leakage from the third TFT to Acom, Acom cannot maintain a constant potential, resulting in a large voltage difference between Acom and the CF electrode on the color filter substrate, and it is impossible to successfully complete the dark spot of the pixel electrode.

Abstract

The invention provides a display panel, an array substrate and a dark attunement method thereof. The dark attunement method comprises the steps that when a pixel electrode anomaly exists, a pixel electrode and a data line are disconnected; a drain electrode of a thin film transistor and an overlap area of a shading electrode are fused; the shading electrode is directly loaded to the pixel electrode. Accordingly, dark attunement is achieved conveniently.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display panel, an array substrate and a method for making dark spots thereof. 【Background technique】 [0002] Liquid crystal displays have many advantages such as thin body, power saving, and no radiation, and have been widely used. Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module (Backlight Module). The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light from the backlight module to produce a picture. [0003] Among them, Thin Film Transistor-Liquid Crystal Display (TF T-LCD) has been developed rapidly and widely used in recent years due to its low ...
