Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] An embodiment of the present invention provides a display substrate for a curved liquid crystal display. The display substrate includes: a substrate and a plurality of spacers arranged on the substrate; the plurality of spacers include a plurality of columns arranged in parallel along the row direction The first spacer, the substrate is divided into a plurality of regions along the row direction; each region is provided with at least one row of first spacers, and the restraining force of the first spacers in the first region is greater than that of the first spacers in the second region A suppression force of a spacer, the suppression force is the force used to maintain the distance between the upper substrate and the lower subst...

Abstract

The invention discloses a display base board for curved surface liquid crystal display, a display panel, and a display device, and belongs to the field of display. The display base board comprises a base board and multiple insulation pads arranged on the base board; the multiple insulation pads comprise multiple columns of first insulation pads arranged in the line direction in parallel, the base board is divided in the line direction into multiple regions; at least one column first insulation pads are arranged in each region, the inhibition force of the first insulation pads in the first region is greater than the inhibition force of the first insulation pads in the second region, the inhibition force is used for maintaining the spacing force between the upper base board and the lower base board of the curved surface liquid crystal display; the first region is a region closer to the center of the base board for any two adjacent regions. Because the inhibition force of the insulation pads in the middle of the base board is greater than the inhibition force of the insulation pads on the two sides, the insulation pads in the middle of the display base board can provide a greater counter acting force to inhibit the spacing between the upper base board and the lower base board from being further reduced, so that the uniformity of the box thickness is ensured.

Description

technical field [0001] The invention relates to the display field, in particular to a display substrate, a display panel and a display device for a curved liquid crystal display. Background technique [0002] Thin Film Transistor Liquid Crystal Display (English Thin Film Transistor Liquid Crystal Display, referred to as TFT LCD) is the mainstream display product at the present stage, which has the characteristics of low energy consumption, low production cost, and no radiation. [0003] The liquid crystal display panel in TFT LCD is mainly composed of a color filter substrate and an array substrate in a box, and a plurality of columnar spacers (English Photo Spacer, referred to as PS) are arranged between the two to maintain a certain gap to inject liquid crystal. This gap is called the box thickness (English Cell Gap). The thickness of the cell must maintain a fixed value to ensure that the thickness of the liquid crystal display panel is consistent. Therefore, in the flat...
