Problems solved by technology

[0002] Curved Display (Curved Display) is a curved design that surrounds the entire screen towards the viewer, which can provide a wider viewing angle and a wide panoramic image effect, and reduce the distortion of off-axis viewing when viewing at a close distance. However, the existing curved display has uneven brightness in the L0 state (that is, the screen is completely black state) caused by bending, which is called Curved L0 Mura.

Embodiment Construction

[0027] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0028] The present invention firstly provides a curved display panel, such as figure 1 As shown, including the array substrate 101 and the color filter substrate 102 arranged oppositely, the cell thickness of the central region of the curved display panel is different from that of the peripheral region, so that the light leakage in the peripheral region is less than the first set value.

[0029] The severe light leakage in the peripheral area of ​​the curved display panel in the prior art is caused by the stress inside the glass in the bent state, which causes the optical delay in different parts of the curved display panel to be different in size and direction. The optical delay caused by bending in different areas light leakage due to changes. When th...

Abstract

The invention provides a curved display panel and a curved display. The curved display panel includes an array substrate and a color filter substrate disposed opposite to each other, a spacer is arranged between the array substrate and the color filter substrate, and the thickness of the box in the middle area of ​​the curved display panel is different from that in the peripheral area. etc., so that the amount of light leakage in the peripheral area is different from that in the middle area in a completely black state. The curved display includes the curved display panel provided by any embodiment of the present invention. The curved display panel and the curved display provided by the present invention can prevent uneven brightness in a completely black state of the screen caused by the curvature of the curved display panel.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a curved display panel and a curved display. Background technique [0002] Curved Display (Curved Display) is a curved design that surrounds the entire screen towards the viewer, which can provide a wider viewing angle and a wide panoramic image effect, and reduce the distortion of off-axis viewing when viewing at a close distance. However, the existing curved display has uneven brightness in the L0 state (that is, the screen is completely black state) caused by bending, which is called Curved L0 Mura. Contents of the invention [0003] In view of this, the present invention provides a curved display panel and a curved display. It can prevent uneven brightness in a completely black state of the screen caused by the bending of the curved display panel. [0004] In view of this, the present invention provides a curved display panel, including an array substrate a...
