Abstract: A display panel, a display panel manufacturing method, and a display screen are provided. The display panel includes: a substrate, the substrate including a plurality of sub-pixel regions, each of the sub-pixel regions including a first region and a second region, the first region being provided with the substrate, a buffer layer, and a pixel circuit layer, and the second region being provided with the substrate; and a first electrode disposed on the second region of each of the sub-pixel region and directly contacting the substrate. Each sub-pixel region is divided into the first region and the second region, the first region is provided with the substrate, the buffer layer and the pixel circuit layer, the second region is provided with the substrate and the first electrode directly contacting the substrate, and no inorganic film is provided between the first electrode and the substrate.

Abstract: Embodiments of this application provides a channel information feedback method and a communication apparatus. In the method, first information and a strongest coefficient indicator (SCI) have a same priority in uplink control information (UCI) sent by a terminal device. The first information indicates a second frequency domain discrete Fourier transform (DFT) vector set selected by the terminal device, and the SCI indicates a space-frequency vector corresponding to a strongest coefficient in a first space-frequency vector set corresponding to the second frequency domain DFT vector set and channel state information reference signal (CSI-RS) ports selected by the terminal device. In other words, the SCI indicates the space-frequency vector that corresponds to the second frequency domain DFT vector set selected by the terminal device and that corresponds to the strongest coefficient.

Abstract: A screen control method is provided. The method is implemented in a terminal device having a first screen, a second screen, and a lens, the first screen and the second screen being disposed facing against one another. The method includes obtaining a command configured to instruct to display the image captured by the lens on the second screen. The method also includes controlling display of the image captured by the lens on the second screen based on the command.
