Optical structure, display panel, display device and manufacture method

Abstract

The invention provides an optical structure, a display panel, a display device and a manufacture method, and relates to the technical field of display. The optical structure comprises a first transparent electrode and a second transparent electrode which are arranged oppositely, as well as an electrochromic layer positioned between the first transparent electrode and the second transparent electrode, and the electrochromic layer can be switched between a transmitting state and a non-transmitting state under the effect of an electric field between the first transparent electrode and the secondtransparent electrode. According to the optical structure, the transmittance of the electrochromic layer can be flexibly controlled through the effect of the electric field, and the non-transmitting part of the electrochromic layer can be used as a black matrix. Compared with the prior art, the scheme has the advantages that the non-transmitting position of the electrochromic layer can be accurately controlled or changed, and the position of the black matrix can be adjusted. In actual application, the misplaced black matrix can be modified for the display device by adopting the scheme, and light leakage of a display image can be avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an optical structure, a display panel, a display device and a manufacturing method. Background technique [0002] The black matrix is ​​a pattern used for light shielding in the display device, and is arranged on the display area and the non-display area of ​​the display device. [0003] Since the black matrix is ​​a pattern in the box of the display device, it has been fabricated on the inside of the box of the substrate before the box is aligned with the display device. After the display device aligns the boxes, 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 shielded area. In particular, after the black matrix in the display area is shifted, pixel color mixing will occur, which will affect the display effect of the picture and bring bad experien...

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
