Abstract
Provided are a display substrate, a display apparatus and a display method therefor. The display substrate includes: a base substrate; pixel units on the base substrate; and an electrochromic structure on a side of the pixel units that is away from the base substrate. The transmittance of the electrochromic structure is positively correlated with the brightness of the pixel units when displaying an image, such that the contrast of the display substrate is improved, and the display effect is improved.
