  • Patent number: 12342711
    Abstract: A display substrate and a mask plate assembly includes a base substrate, a pixel defining layer, a functional layer, a cathode layer, and a covering layer that are sequentially stacked in a direction away from the base substrate, wherein the size of orthographic projection of the functional layer on the base substrate is jointly determined by the size of a display area and a first minimum distance. The first minimum distance is the minimum distance in a direction from the display area to a non-display area and between the boundary of the display area and the boundary of the functional layer, and is determined by a first shadow width of the functional layer extending from the display area to the non-display area. The first shadow width is the maximum width of a shadow area formed within a preset region when the functional layer is vapor deposited in the preset region.

  • Publication number: 20240205432
    Abstract: The technology of this application relates to an encoding method, an encapsulation method, a display method, an apparatus, and an electronic device. The encoding method includes obtaining a to-be-encoded image, determining N encoding scales (N is an integer greater than 1) for the image, determining an encoding parameter corresponding to each of the N encoding scales, to obtain N groups of encoding parameters, and encoding the image N times by using a preset single-scale encoder based on the N groups of encoding parameters to obtain N groups of bitstream data. In this way, the image is encoded to obtain the bitstream data with a small data amount (namely, the bitstream data with a low encoding scale), so that when a network fluctuates, the bitstream data corresponding to the image can arrive at a decoder side with a higher probability, thereby ensuring smoothness of video playing.
