Display panel and manufacturing method thereof, curved display panel and curved display device

Abstract

The invention discloses a display panel and a manufacturing method thereof, as well as a curved-surface display panel and a curved-surface display device, which are used for avoiding phenomena including light leak, colour mixture and aperture ratio reduction caused in a curving process of the display panel. The display panel comprises a first substrate, a second substrate, a pixel structure, an electrochromic material layer, first transparent electrodes and second transparent electrodes, wherein the pixel structure is distributed to form an array, and is arranged on one side, away from the second substrate, of the first substrate; the electrochromic material layer is arranged between the first substrate and the second substrate; the first transparent electrodes are arranged between the electrochromic material layer and the pixel structure, and have the same shapes as opening areas of the pixel structure; the second transparent electrodes are arranged between the electrochromic material layer and the second substrate, and at least part of orthographic projections of the second transparent electrodes on the first substrate or the second substrate are overlapped with orthographic projections of the first transparent electrodes on the first substrate or the second substrate.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof, a curved display panel and a curved display device. Background technique [0002] With the development of display technology, new display products emerge in an endless stream. At present, as a new display technology, curved display is more and more respected by panel manufacturers and consumers. The curved display panel has a curved display screen. Because it can achieve the consistency of the distance between each pixel of the display screen and the human eye, it can more truly restore the visual experience of the human eye and give the viewer a better sense of presence. Flat display panels are more competitive. [0003] When making a curved display panel, it is necessary to bend the original flat display panel, because the counter substrate (Color Filter) and the array substrate (TFT) will be based on the center of ...

AI Technical Summary

Problems solved by technology

As a result, the display of the display panel is not uniform under the same driving conditions, resulting in defects such as light leakage, color mixing, and lower aperture ratio, which affect the display effect

[0004] To sum up, in the manufacturing process of the existing curved display panel, the phenomenon of light leakage, color mixing and reduction of the aperture ratio will be caused by the bending process of the array substrate.
