Abstract: A display module and a display apparatus. The display module includes a display panel and a first light control panel. The first light control panel includes a first base and a second base arranged opposite to each other and a first light control liquid crystal layer arranged between the first base and the second base. The first base includes a first substrate, a first electrode, a first alignment layer, and a first polarizer. The second base includes a second substrate, a second electrode, a second alignment layer, and a second polarizer. A polarization axis of the first polarizer is perpendicular to a polarization axis of the second polarizer. An alignment direction of the first alignment layer is parallel to an alignment direction of the second alignment layer. An angle between the alignment direction of the first alignment layer and the polarization axis of the first polarizer is α, 90°>α>0°.

Abstract: Anti-peep display assembly and display device are provided. The anti-peep display assembly includes a backlight module, a first birefringence control type liquid crystal cell, a second birefringence control type liquid crystal cell, and a display liquid crystal cell. Along a thickness direction of the anti-peep display assembly, the first birefringence control type liquid crystal cell and the second birefringence control type liquid crystal cell are between the backlight module and the display liquid crystal cell, and the first birefringence control type liquid crystal cell is between the second birefringence control type liquid crystal cell and the backlight module. A first polarizer is arranged on a side of the display liquid crystal cell away from the second birefringence control type liquid crystal cell, and a second polarizer is arranged between the display liquid crystal cell and the second birefringence control type liquid crystal cell.

Abstract: A viewing angle controller, a display panel, and a display device. The viewing angle controller includes at least one liquid crystal controlling box. The liquid crystal controlling box includes a first liquid crystal controlling box including a first substrate, a second substrate, and a first liquid crystal layer arranged between the first substrate and the second substrate. The first liquid crystal controlling box operates in a first state or in a second state. A transmittance of first light passing through the first liquid crystal controlling box in the second state is lower than one or both of a transmittance of the first light in the first state and a transmittance of second light passing through the first liquid crystal controlling box in the second state. An inclination of the first light is greater than that of the second light relative to the front-viewing direction of the viewing angle controller.
