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 viewed at a close distance. 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 CurvedL0Mura

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 surface display panel and a curved surface displayer. The curved surface display panel comprises an array substrate and a color film substrate which are arranged oppositely. A spacer is arranged between the array substrate and the color film substrate. The box thickness of the middle area of the curved surface display panel is unequal to that of the periphery area of the curved surface display panel, and therefore the light leakage amount generated when the periphery area is in a full dark state is different from that of the middle area. The curved surface displayer comprises the cured surface display panel provided by any embodiment of the invention. The curved surface display panel and the curved surface displayer can prevent brightness non-uniformity caused by curving of the curved surface display panel under the full black state of a screen.

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 viewed at a close distance. There is a phenomenon of uneven brightness in the L0 state (that is, the screen is completely black state) caused by the bending of the existing curved surface display, which is called Curved L0Mura. 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, inclu...
