A backlight module includes stacked light guide plates, a light source module, and a deflecting film. Each light guide plate has a light-incident surface, a light exit surface, a bottom surface, and a light guide structure. The light exit surface and the bottom surface are placed on two opposite sides of the light guide plate and both connected to the light-incident surface, and the light guide structure is formed on the bottom surface. The light-incident surfaces are placed on a light entry side and arranged along a stacking direction. The light source module is disposed on the light entry side and includes light-emitting elements. The light-emitting elements are arranged in a single line along the light-incident surface of each light guide plate, and each light-emitting element has a light emitting surface facing the light-incident surfaces of the plurality of light guide plates.

Backlight module including light guide structure

A backlight module includes a light guide plate, a light source, a low-reflective element, and a light-shielding element. The light guide plate has a light-incident surface, a light-exiting surface, and a bottom surface. The light source includes a circuit board and light-emitting elements. The circuit board is located on the light-exiting surface. The light-emitting elements are disposed on the circuit board and spaced apart. Each light-emitting element has a light-emitting surface. The low-reflective element is located on the bottom surface of the light guide plate and has a base part and extended parts. The extended parts are spaced apart and staggered the light-emitting elements. The light-shielding element is located between the circuit board and the light-exiting surface and includes adhesive members connecting the light-shielding element with the light guide plate. The adhesive members are spaced apart and staggered with the light-emitting elements.

Backlight module

A backlight module includes the following features. A light guide plate has a viewing angle convergence structure, a light-incident surface and a surface connected to the light-incident surface. The viewing angle convergence structure is located at the surface. The prism plate has first prism columns and second prism columns disposed cross to each other. The inverse prism plate has third prism columns respectively having a first side surface and a second side surface. The first side surface and the second side surface are connected to each other and are respectively connected to the second surface. The first side surface faces a side of the backlight module with the light-emitting element, and the second side surface faces away from the side. An included angle between the first side surface and the second surface is larger than an included angle between the second side surface and the second surface.

A backlight module includes a first and a second light guide plate; a turning film; a first, a second, and a third light source module. The first light guide plate has a first light entrance surface, a first light-emitting surface, a first bottom surface, and a light guide structure formed on the first bottom surface. The second light guide plate is disposed above the first light-emitting surface and has a second light-emitting surface, a second bottom surface, a second light entrance surface, a third light entrance surface, and optical microstructures, wherein the second and the third light entrance surface are located on two opposite sides of the second light guide plate. The turning film is disposed between the two light guide plates. The first, the second, and the third light source module are disposed aside the first, the second, and the third light entrance surface, respectively.
