1. 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.
