  • Patent number: 10823895
    Abstract: The present disclosure provides a light-emitting module. The light-emitting module includes a light guide plate, a light source, and a brightness adjustment element. The light guide plate has a light incident surface, a front surface, and a back surface opposite the front surface. The light incident surface is located between the front surface and the back surface and is adjacent to the front surface and the back surface. The brightness adjustment element has a strip portion and at least one protruding portion. The strip portion has a first edge proximal to the light incident surface. The protruding portion is located on the first edge of the strip portion, and the protruding portion is aligned with the light source and extends away from the first edge.

  • Patent number: 9739925
    Abstract: The present disclosure provides a light-emitting module. The light-emitting module includes a light guide, a plurality of light source and a light-adjusting film. The light-adjusting film has a first light absorption portion, a plurality of second light absorption portions and a plurality of light reflection portions. The second light absorption portions are individually extended from the projection position of the light sources on the first light absorption portion, and may absorb part of the light in front of the light sources; and each of the light reflection portions is between two of the adjacent second light adsorption portions, and may reflect the light shinning thereon.

  • Patent number: 9733418
    Abstract: A light source module is provided. At least one light-emitting device emits light and is disposed beside the light guide plate. A light guide plate includes a first surface, a second surface being opposite to the first surface and a light-entering surface connecting the first surface with the second surface. At least one first light guide end, which is located in front of the light-emitting device, and at least one second light guide end, which is connected to the first light guide end, are located on a side of the light guide plate where the light-entering surface is located. A first light-transmitting medium at least located at the first light guide end on the first surface has a refractive index which is larger then a refractive index of a medium or space located at the second light guide end on the first surface. A display device is also provided.

  • Patent number: 9535205
    Abstract: A display device including a reflective display panel, a plurality of electrical or optical element layers, and at least one light-emitting element is provided. The electrical or optical element layers are stacked above the reflective display panel. One of the electrical or optical element layers is a light guide plate. The light-emitting element is disposed beside the light guide plate. A plurality of transparent medium layers are respectively located between every two adjacent ones of the reflective display panel and the electrical or optical element layers and above the electrical or optical element layer most away from the reflective display panel among the electrical or optical element layers. At least one of the transparent medium layers above the light guide plate is a gas layer.

  • Patent number: 9519100
    Abstract: A display apparatus is provided. A display unit has a display region. A protecting cover has a patterned region, wherein the patterned region does not overlap the display region. A light guide plate is disposed between the display unit and the protecting cover and has a first light scattering region and a second light scattering region. The first light scattering region at least partially overlaps the display region, and the second light scattering region at least partially overlaps the patterned region. A light emitting unit emits a light beam to the light guide plate. After the light beam enters the light guide plate, a part of the light beam is scattered to the display region by the first light scattering region and another part of the light beam is scattered to the patterned region by the second light scattering region.
