Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an array substrate and a display panel. The drains of the shared thin-film transistors in the pixel units of the array substrate are connected to the DBS electrode lines, thereby overcoming the problems caused by deep hole connections in the prior art. The opening ratio is low, and the risk of ITO climbing line disconnection is high

Embodiment 1

[0038] Based on Embodiment 1 of the present invention, Embodiment 2 of the present invention provides a display panel, which includes a color filter substrate, the aforementioned array substrate, and a liquid crystal display layer disposed between the array substrate and the color filter substrate.

[0039] The color filter substrate includes a glass substrate, and a common electrode layer C-com arranged on the glass substrate, and the common electrode layer C-com is made of indium tin oxide (ITO) on the entire surface.

[0040] Wherein, when the display panel is photo-matched, the common electrode layer C-com on the color filter substrate forms a first storage capacitor with the main pixel electrode, and forms a second storage capacitor with the slave pixel electrode. More specifically, the capacitance values ​​of the first storage capacitor and the second storage capacitor are equal.

[0041] Specifically, when the liquid crystal panel is photo-matched, the voltage provided ...

Abstract

The present invention provides an array substrate and a display panel, wherein the array substrate includes: a plurality of scanning lines and a plurality of data lines respectively intersecting the plurality of scanning lines to define a plurality of pixel units; each pixel unit It includes a master pixel area and a slave pixel area, and the slave pixel unit includes a slave pixel electrode; a plurality of DBS electrode lines are arranged above the plurality of data lines; For the shared thin film transistor, the gate of the shared thin film transistor is connected to the corresponding scanning line, the source of the shared thin film transistor is connected to the slave pixel electrode, and the drain of the shared thin film transistor is connected to the corresponding DBS electrode line. The present invention removes the deep hole connection between the source or drain of the shared thin film transistor and the A-com common electrode in the prior art, increases the area of ​​the display area of ​​the product, increases the aperture ratio, and thus improves the electrical properties of the 3T structure design stability.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to an array substrate and a display panel. Background technique [0002] In the 3T pixel unit structure, the pixel unit is divided into a main pixel area (Main Pixel) and a sub pixel area (SubPixel). The main pixel area is driven by a TFT (Thin Film Transistor) thin film transistor, and the sub pixel area is driven by a thin film transistor and a The shared thin film transistors used to pull down the voltage of the slave pixel area are jointly driven. In the prior art, the structure of the pixel unit usually has two connection methods, one such as Figure 1-2 As shown, the main pixel area includes a main thin film transistor TFT1 and a main pixel electrode, the gate of TFT1 is connected to the corresponding scanning line Gate, the source of TFT1 is connected to the corresponding data line Data, and the drain of TFT1 is connected to the main pixel electrode. The slav...
