Optical structure, display panel, display device and manufacturing method

Abstract

The invention provides an optical structure, a display panel, a display device and a manufacturing method, and relates to the field of display technology. Wherein, the optical structure includes: a first transparent electrode and a second transparent electrode arranged oppositely; an electrochromic layer located between the first transparent electrode and the second transparent electrode, between the first transparent electrode and the second transparent electrode Under the action of an electric field, the electrochromic layer can be switched between a light-transmitting state and an opaque state. The invention can flexibly control the light transmittance of the electrochromic layer through the action of the electric field. Wherein, the opaque part of the electrochromic layer can be used as a black matrix. Compared with the prior art, the advantage of the solution of the present invention is that the opaque position of the electrochromic layer can be precisely controlled or changed, thereby realizing the position adjustment of the black matrix. In practical application, the solution of the present invention can correct the misaligned black matrix of the display device, and can avoid light leakage in the display screen.

Description

Technical field [0001] The present invention relates to the field of display technology, and particularly to an optical structure, display panels, display apparatus and manufacturing method. Background technique [0002] The black matrix pattern for the light shielding means is a display, disposed on the display region and the non-display area of ​​the display device. [0003] Since the black matrix pattern is a display box apparatus, the display device thus before the cartridge in the cartridge had been produced inside the substrate. When the display device after completion of the cartridge, the cartridge due to the presence of errors, the actual position of the black matrix must inevitably shifted to the expected position, resulting in light leakage occlusion region. In particular display pixel color mixing phenomenon will appear after the black matrix region offset, resulting in the screen display is affected, giving users a bad experience. In addition, some flexible display s...

AI Technical Summary

Problems solved by technology

When the display device completes box alignment, due to the existence of box alignment errors, the actual position of the black matrix will inevitably deviate from the expected position, resulting in light leakage in the blocked area

Especially after the black matrix in the display area is shifted, pixel color mixing will occur, which will affect the display effect of the screen and bring bad experience to users.

In addition, for some screen bendable display devices (such as flexible display devices), the black matrix may also be misaligned after being bent for a long time

[0004] At present, the black matrix is ​​formed by etching after depositing the black matrix material, and the position cannot be changed after production, so the existing technology cannot solve the problem of misalignment of the black matrix in the display device
