Problems solved by technology
As a result, the peripheral spacers 110 cannot support the curved display panel 100, and under the action of atmospheric pressure or other pressures, the liquid crystals in the curved display panel 100 further accumulate on both sides, resulting in a mismatch between the height of the spacers on both sides and the change in the cell thickness, resulting in Poor display and uneven display caused by yellowing around the curved display panel 100

The invention provides a curved surface display panel and a display module. The curved surface display panel comprises an array basal plate, a color film basal plate, a liquid crystal molecule and a plurality of spacers, wherein the color film basal plate is opposite to the array basal plate, and a first region and a second region are formed between the array basal plate and the color film basal plate; the liquid crystal molecule is positioned between the array basal plate and the color film basal plate; the spacers are positioned between the array basal plate and the color film basal plate, each of the spacers comprises a plurality of first spacers which are positioned in the first region and have the same first height h1, and a plurality of second spacers which are positioned in the second region and have the same height h2, the second height h2 of the second spacers is increased along with the increase of the distance H between the array basal plate and the color film basal plate, and the second height h2 of each of the second spacers is larger than the first height h1 of each of the first spacers. According to the curved surface display panel and the display module provided by the invention, the displaying effect of the display module is improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a curved display panel and a display module. Background technique [0002] With the rapid development of display technology, users' requirements for display products are gradually increasing. Curved surface display devices are attracting more and more attention due to their beautiful appearance, realistic picture sense and comfortable human eye experience. However, in the currently used curved surface display devices, due to the different forces on the center of the display panel and the periphery, the thickness of the display panel varies greatly, so the periphery is prone to yellow uneven brightness (mura), and in severe cases, it will also affect the display quality, resulting in curved surfaces. The display device cannot display normally. [0003] Specifically, for an existing flat display panel, the thickness of the entire display panel is uniform, and the height of the sp...
