Abstract: A display apparatus and a displaying method thereof are provided. The display apparatus includes a transmissive display panel, a liquid crystal glass, a backlight module and a transparent polarizer film. The liquid crystal glass is disposed at a side of the transmissive display panel. The liquid crystal glass has a transparent state and an atomization state and is adapted to switch between the transparent state and the atomization state. The backlight module is disposed at a side of the liquid crystal glass away from the transmissive display panel. The backlight module includes a transparent light-guiding plate and at least one light bar. The liquid crystal glass is located between the transmissive display panel and the transparent light-guiding plate. The transparent polarizer film is disposed at a side of the transparent light-guiding plate away from the liquid crystal glass.

Abstract: A backlight module includes a first surface light source assembly, a second surface light source assembly disposed above the first surface light source assembly, a first optical film disposed above the second surface light source assembly and including a plurality of prisms arranged along a first direction, and a light filter element disposed between the first and second surface light source assemblies. Both of the first surface light source assembly and the second surface light source assembly include a light emitting unit and a light guide plate. Each prism has a tip end facing the second surface light source assembly. The light filter element is configured to allow an incident light ray within a predetermined range of incident angle to pass therethrough. The backlight module can be switched between a narrow viewing angle mode and a wide viewing angle mode. Related driving method and display apparatus are also provided.

Abstract: A light source module including a first backlight module, a second backlight module, a turning film, and a first absorptive polarizer film is provided. The first backlight module has a first side and a second side. The first backlight module includes a first light guide plate (LGP) having a first light incident surface and a first light source disposed beside the first light incident surface. The second backlight module is arranged at the second side. The second backlight module includes a second LGP having a second light incident surface and a second light source disposed beside the second light incident surface. The turning film is arranged at the first side. The turning film includes a plurality of reverse prisms. The reverse prisms extend along an extension direction. The first absorptive polarizer film is disposed between the first backlight module and the second backlight module. A display device is also provided.
