  • Patent number: 11947217
    Abstract: A backlight module including a light guide plate, a light source, a diffuse reflector and a light-splitting film is provided. The light guide plate has a light incident surface, and a light-emitting surface and a bottom surface which are respectively connected to the light incident surface and opposite to each other. The light source is disposed on one side of the light incident surface of the light guide plate. The diffuse reflector is disposed on one side of the bottom surface of the light guide plate. The light-splitting film is disposed between the light guide plate and the diffuse reflector. The light-splitting film has a substrate and a plurality of first optical microstructures disposed on one side of the substrate. An extending direction of the first optical microstructures intersects with the light incident surface of the light guide plate. A display apparatus using the backlight module is also provided.

  • Patent number: 11852859
    Abstract: A light source module includes a light guide plate, a light-emitting element, and first and second prism sheets. One of the light-emitting surface and the bottom surface of the light guide plate has strip-shaped microstructures. The bottom surface has bottom microstructures, and the angle between the first surface of each bottom microstructure and the bottom surface is 1° to 17°. The first prism sheet is disposed on the light-emitting surface and between the light-emitting surface and the second prism sheet and includes first prism rods. The second prism sheet includes second prism rods. The aspect ratio of the strip-shaped microstructure is greater than 0.2. The angle between the maximum luminance direction of the light from the light-emitting surface and the normal direction of the light-emitting surface is less than 70°. The light-emitting angle range is less than 40°. A display device including the light source module is also provided.

  • Publication number: 20230213697
    Abstract: A backlight module includes a light guide plate, a light source, multiple first optical microstructures, and multiple second optical microstructures. The first optical microstructures and the second optical microstructures are disposed on the bottom surface of the light guide plate. Each of the first optical microstructures has a first light receiving surface facing the light source. Each of the second optical microstructures has a second light receiving surface facing the light source. A first angle is included between the first light receiving surface and the bottom surface. A second angle is included between the second light receiving surface and the bottom surface. The second angle is different from the first angle. A display apparatus adopting the backlight module is also provided.
