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

Disclosed are a display substrate, a liquid crystal display panel and a curved liquid crystal display apparatus. The display substrate comprises: a first substrate (100); and a plurality of first spacers (101) located on the first substrate (100) and configured to keep the first substrate (100) separate from a second substrate (200). In a top view, the initial planar dimensions of the plurality of first spacers (101) are substantially identical, wherein first spacers (101) located in a first region (100A) are configured to together provide a first support force for the second substrate (200) when the first substrate (100) and the second substrate (200) have a spacing therebetween in the first region (100A), and first spacers (101) located in a second region (100A) are configured to together provide a second support force for the second substrate (200) when the first substrate (100) and the second substrate (200) have the spacing therebetween in the second region (100A), the first support force being substantially greater than the second support force. In the top view, the first region (100A) and the second region (100A) do not overlap with each other, but are substantially identical in size and shape. In this way, the uniformity of the cell thickness of a curved liquid crystal display apparatus 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...
