Abstract: A display substrate and a display apparatus are provided. The display substrate includes a base substrate; sub-pixels arranged in an array and on the base substrate; data line groups on the base substrate; each data line group includes data lines, each of which is connected to one column of sub-pixels; data selectors on the base substrate and connected to the data line groups in a one-to-one correspondence; data lines in a same data line group are connected to a same data selector; and data selection signal lines, wherein different data selection signal lines output different data selection signals; and different data lines connected to a same data selector correspond to different data selection signal lines, respectively. The display panel provided may effectively reduce the resistance on the data selection signal lines, thereby reducing the delay of the data selection signals and further improving the charging uniformity of sub-pixels.

Abstract: Provided are a display panel and a display device, relating to the field of display technologies. The display panel includes a display substrate, a diffusion sheet, a transflective film, and a fingerprint identification circuit. Light of a target wavelength emitted by the fingerprint identification circuit may be reflected by an obstacle, and the light of the target wavelength reflected by the obstacle may be irradiated to the fingerprint identification circuit through at least one through hole in the diffusion sheet. The fingerprint identification circuit performs fingerprint identification according to the received light of the target wavelength reflected by the obstacle. Since an orthographic projection of the fingerprint identification circuit onto the display substrate is within a display area of the display substrate, the fingerprint identification circuit can be prevented from occupying a non-display area of the display substrate. Therefore, the non-display area can be small, and thus, the display device has a relatively high screen-to-body ratio.
