Abstract: A display substrate is provided. The display substrate includes a respective encapsulated unit and a separation structure substantially surrounding the respective encapsulated unit. The respective encapsulated unit includes a color conversion layer comprising one or more color conversion blocks; and a respective encapsulating block in an encapsulating layer encapsulating the one or more color conversion blocks. The encapsulating layer is at least partially absent in a peripheral region around the respective encapsulated unit.

Abstract: A display driving circuit, a method of driving a display driving circuit, a display panel, and a display device are provided. The display driving circuit includes a compensation circuit and at least one pixel circuit electrically connected to the compensation circuit. The pixel circuit is configured to receive a data compensation signal and control a current magnitude of a driving current flowing through a light-emitting element according to the data compensation signal, so as to apply an operating voltage to a first terminal of the light-emitting element. The compensation circuit is configured to receive the operating voltage and a data voltage and adjust the data compensation signal according to a difference between the operating voltage and the data voltage.

Abstract: A photomask and an exposure method are provided. The photomask includes a photomask body including a first surface and a second surface opposite to each other; and a first light-transmissive region penetrating through the first surface and the second surface, wherein a light adjustment component is in the first light-transmissive region and configured to converge a first light beam incident onto the first surface to a second light beam emergent from the second surface, and a cross-sectional area of the first light beam sectioned by the first surface is larger than that of the second light beam sectioned by the second surface.

Abstract: A white balance adjustment method and system for a display screen, and a display apparatus are provided. The white balance adjustment method includes: step S1, causing each pixel of at least a part of pixels of the display screen to display, with a preset grayscale, color images of sub pixels of all colors in the pixel in turn, and measuring chromaticity coordinate values and actual brightness values of the displayed color images; step S2, calculating an actual brightness ratio among actual brightness values of the sub pixels of all colors; calculating a standard brightness ratio among standard brightness values of the sub pixels of all colors when the display screen displays standard white light; and step S3, comparing the actual brightness ratio and the standard brightness ratio in case of the preset grayscale to obtain a comparison result, and adjusting grayscales of the sub pixels of all colors.
