  • Publication number: 20240402563
    Abstract: A display substrate includes: a base substrate (300), a circuit structure layer (400) and an electronic paper film (500) sequentially disposed on the base substrate (300). The circuit structure layer (400) includes: a plurality of first signal lines (21) extending along a first direction (X), a plurality of second signal lines (22) extending along a second direction (Y), a plurality of drive units, and at least one near field communication coil. The plurality of first signal lines (21) and the plurality of second signal lines (22) intersect to form a plurality of sub-pixel areas. The drive units are located in the sub-pixel area and electrically connected with the first signal lines (21) and the second signal lines (22), and are configured to control the display patterns of the electronic paper film corresponding to the sub-pixel areas.
