摘要： A backlight module suitable for thermal coupling with a display panel includes a light guide plate which has a light incident surface and a light exiting surface, a light source configured such that light emitted therefrom enters the light guide plate from the light incident surface and exits the light guide plate from the light exiting surface to irradiate onto the display panel, a heat sink configured to partially accommodate the light guide plate and the light source, and a heat conducting device disposed between the heat sink and the display panel to conduct heat generated from the display panel to the heat sink. The backlight module can quickly dissipate heat generated from a heat concentrated area of the display panel to the outside.

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.
