    Abstract: A backlight module includes a light guide plate having a bottom surface, a light exit surface, and a light incident surface a substrate located on a side of the bottom surface away from the light exit surface; first light-emitting devices located on a side of the substrate proximate to the bottom surface second light-emitting devices disposed opposite to the light incident surface; and a prism sheet located on a side of the light guide plate away from the substrate. The first light-emitting devices are configured to emit first light, so that the first light passes through the light guide plate and the prism sheet to become light of a first viewing angle. The prism sheet is configured to cooperate with the light guide plate to modulate second light emitted by the second light-emitting devices into light of a second viewing angle which is smaller than the first viewing angle.
