Array substrate and curved-surface liquid crystal display

Abstract

The invention provides an array substrate and a curved-surface liquid crystal display. A light shading electrode is arranged above a data line and used to control a liquid crystal corresponding to position of the data line to maintain a non-deflection state so as to realize light shading effect; the light shading electrode is insulated and spaced with each of a first metal layer, a second metal layer and a pixel electrode, in other words, the light shading electrode is in an idle state. Compared with the prior art, the array substrate has the advantages that the light shading electrode is not in electrical connection with a common electrode line anymore, so that horizontal crosstalk can be prevented, and display quality of a panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate and a curved liquid crystal display. Background technique [0002] A Liquid Crystal Display (LCD) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer screen, etc., occupy a dominant position in the field of flat panel display. [0003] Generally, a liquid crystal display device includes a housing, a liquid crystal panel disposed in the housing, and a backlight module disposed in the housing. Among them, the structure of the liquid crystal panel is mainly composed of an array substrate (ThinFilmTransistorArray Substrate, TFT Array Substrate), a color filter substrate (Color Filter Substrate, CFSubstrate), and a liquid crystal layer (Liquid Crystal Layer) arranged between the two substrates. The wo...

[0005] but if figure 1 as shown, figure 1 It is an equivalent circuit diagram of an existing array substrate using DBS technology. The array substrate includes: a plurality of sub-pixels arranged in an array, and each sub-pixel includes a switching thin film transistor T1, a pixel electrode P, and a common electrode line Acom of the array substrate. , and a light-shielding electrode, the gate of the switching thin film transistor T1 is connected to the scan line Gate, the source is connected to the data line Data, and the drain is electrically connected to the pixel electrode P, and the light-shielding electrode is electrically connected to the array substrate common electrode line Acom The part where the pixel electrode P overlaps with the array substrate common electrode line Acom forms a storage capacitor Cst, and the part where the data line Data overlaps with the light-shielding electrode forms a disturbance capacitor Cdc. At this time, when the panel is displayed, the data on the data line Data The voltage change will affect the common voltage Acom of the array substrate through the interference capacitance Cdc, causing undesirable phenomena such as horizontal crosstalk (H-crosstalk)
