Abstract
The present disclosure provides a display screen and a display device. The display screen includes an electrochromic layer located in a blind via area. The electrochromic layer includes a first electrode layer, an electrochromic material layer, and a second electrode layer stacked in sequence. By means of the display screen and the display device of the present disclosure, the blind via area and an under-screen camera can be shielded when a photographing function is disabled, so that the appearance is sightlier, the privacy is protected, and the lighting of the under-screen camera is not affected when the photographing function is enabled.
Claims12
A display screen, having a blind via area, wherein the display screen comprises:
- a first polarizing layer disposed on a light exit side of the display screen, wherein a first opening is provided at a position on the first polarizing layer corresponding to the blind via area;
- and
- an electrochromic layer, wherein at least part of the electrochromic layer is located in the blind via area, the electrochromic layer is disposed in an array substrate of the display screen or disposed in the first opening, and the electrochromic layer comprises:
- a first electrode layer;
- an electrochromic material layer disposed on the first electrode layer;
- and
- a second electrode layer disposed on a side of the electrochromic material layer away from the first electrode layer;
- wherein in the blind via area, the array substrate comprises:
- a substrate, wherein the electrochromic layer is disposed on the substrate;
- and
- an alignment layer disposed on a side of the electrochromic layer away from the substrate.
A display screen, having a blind via area, wherein the display screen comprises an electrochromic layer, and at least part of the electrochromic layer is located in the blind via area;
- and
- wherein the electrochromic layer comprises:
- a first electrode layer;
