Problems solved by technology

But if the area of ​​the contact end of the spacer and the spacer pillow is too small, new problems will occur again, such as figure 2 as shown, figure 2 It is a structural schematic diagram of a display panel in the prior art when a contact problem occurs. When the surface of the display panel is subjected to external pressure F, the color filter substrate 01 will have a certain offset relative to the array substrate 03. When the offset exceeds a certain distance, That is, when the spacer 02 provided on the color filter substrate 01 deviates beyond the supporting edge of the spacer cushion 04 provided on the array substrate 03, after the external force F disappears, the spacer 02 is blocked by the wiring level difference of the array substrate 03. If it cannot or cannot be restored to the original position in time, it will cause light leakage on the display panel. In terms of technology, this bad phenomenon is called Touch Mura.

Abstract

The invention discloses an array substrate, a preparation method of the array substrate and a display panel. The array substrate comprises a plurality of spacer pads for supporting spacers, wherein the supporting end of each spacer pad is provided with at least one concave portion. The array substrate is applied to the display panel, the array substrate is connected with a color film substrate, and the spacer pads correspond to the spacers in a one-to-one mode and are used for supporting the spacers; the supporting end of each spacer pad arranged on the array substrate is provided with one or more concave portions, and the size of the supporting end of each spacer pad can be increased, namely the spacers arranged on the color film substrate can move in a larger range on the spacer pads but the contact area of each spacer and the corresponding spacer pad cannot be increased; meanwhile, by means of the arrangement of the concave portions, friction force between the spacers and the spacer pads can be increased, the spacers can be prevented from deviating when the display panel bears external pressure, and the light leaking phenomenon of the display panel is reduced.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to an array substrate, a method for preparing the array substrate and a display panel. Background technique [0002] Existing display panels are mainly composed of polarizers, array substrates, color filter substrates, liquid crystal layers, and the like. The regular arrangement of the liquid crystal layer can realize color display. The thickness of the liquid crystal layer affects the transmittance of light injected into the liquid crystal panel. When the transmittance is inconsistent, the display will be uneven. Therefore, in order to achieve a uniform display of the display panel, it is very important to ensure a uniform thickness of the liquid crystal layer (cell thickness). . [0003] In the manufacture of liquid crystal display panels, such as figure 1 as shown, figure 1 It is a schematic structural diagram of a display panel in the prior art, and a spacer 02 is usually a...
