摘要： The present application discloses a backlight module and a display device. The backlight module includes a light source assembly, a light concentration structure concentrating light emitted from the light source assembly and emitting the light in a predetermined angle range, a light guide structure guiding the light concentrated by the light concentration structure in a way of mirror reflection out from a light exiting surface of the light guide structure, and a viewing angle switch assembly, wherein the viewing angle switch assembly guides light emitted from the light guide structure outward at a first viewing angle or a second viewing angle.

摘要： A backlight module and a display device are disclosed. The backlight module includes a light guide structure and a light source. The light source includes a first light-emitting assembly and a second light-emitting assembly. A light receiving structure is disposed behind and corresponding to a position of the first light-emitting assembly and is configured to concentrate light emitted by the first light-emitting assembly within a predetermined angle range so that the light is directed outward from the light receiving structure. The light guide structure is disposed behind and corresponding to a position of the light receiving structure and is configured to direct outward the light concentrated in the light receiving structure through specular reflection.

摘要： The present invention provides a display panel and a display module. The display panel includes a first substrate, a first electrode layer, a light control layer, a second electrode layer, and a second substrate. The light control layer includes a first liquid crystal and light blocking layers. When no voltage is applied to the light control layer, the first liquid crystal is configured as an atomized liquid crystal for scattering light. When a voltage is applied to the light control layer, the first liquid crystal is configured as a transparent liquid crystal, thereby effectively improving an anti-peep performance of the display panel.
