摘要: A display panel includes: a base, light-emitting devices, auxiliary light-emitting devices and a texture identification layer disposed above the base. The light-emitting devices are configured to emit light for display. Each auxiliary light-emitting device has a same light-emitting direction as the light-emitting devices and is configured to emit light in response to receiving a control signal during the display panel being in a screen-off state. The texture identification layer is configured to receive reflected light that is reflected to the texture identification layer in light emitted by the auxiliary light-emitting devices to an outside of the display apparatus, so as to perform texture identification.
