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.

Abstract: An embodiment of this disclosure provides a nano-imprinting method, including: applying an imprinting adhesive on a to-be-processed layer of a substrate located in an imprinting chamber; charging the imprinting chamber with a preset gas at a temperature higher than a boiling point of the preset gas, and pressing a nano-imprinting template on the imprinting adhesive; reducing an ambient temperature of the imprinting chamber to a temperature lower than the boiling point of the preset gas and maintaining the temperature for a preset time, such that the preset gas becomes a liquid; irradiating ultraviolet light from a side of the nano-imprinting template away from the imprinting adhesive to cure the imprinting adhesive; raising the ambient temperature of the imprinting chamber to be higher than the boiling point of the preset gas, such that the liquefied preset gas turns back into a gas; and demolding the nano-imprinting template from the imprinting adhesive.

Abstract: A display panel includes a substrate and a grating disposed on a light-emitting side of the display panel. The grating includes a plurality of protruding portions and a plurality of interval portions, each interval portion is located between two adjacent protruding portions. The plurality of protruding portions are arranged on the substrate along a first direction, and each protruding portion extends along a second direction perpendicular to the first direction. Each protruding portion includes an outer surface and a bottom surface; the outer surface is a smooth curved surface, and the bottom surface is a flat surface. A cross-sectional figure of each protruding portion along a thickness direction of the display panel is a first figure; the first figure includes a curve and a bottom edge, and the first figure is a closed figure formed by the curve and the bottom edge. The curve is a cross-sectional figure of the outer surface along the thickness direction of the display panel, and the bottom edge is a cross-sectional figure of the bottom surface along the thickness direction of the display panel.
