  • Publication number: 20230054532
    Abstract: The present application relates to the technical field of display, and discloses a display panel, a preparation method therefor, and a display apparatus. The material of a filter film layer in the display panel comprises a conductive material, so the filter film layer may be used as a detection plate of a fingerprint identification circuit. Moreover, since the filter film layer is located on the side of a display function film layer away from a base substrate, the filter film layer is far away from a signal line in the display function film layer, and is not easily affected by the signal line. When the filter film layer is used as the detection plate, the signal-to-noise ratio of a fingerprint signal detected by the fingerprint identification circuit may be larger, and the fingerprint identification effect may be better.
