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.

Light-emitting module

A waterproof light emitting module is provided. The waterproof light emitting module comprises a circuit board, a light emitting diode, a light guide plate, and a waterproof layer. The light emitting diode is over the circuit board, and having a light emitting surface, a first non-light emitting surface and a second non-light emitting surface. The light guide plate is adjacent to the light emitting surface of the light emitting diode. The waterproof layer covers the first non-light emitting surface and the second non-light emitting surface of the light emitting diode. The waterproof layer includes an adhesive, a substrate, a recessed portion of the light guide plate, a portion of the circuit board or a combination thereof. A display device including the waterproof light emitting module is also provided herein.

Waterproof light emitting module and display device

A light emitting device includes a light guide plate and a light source. The light guide plate has a first surface, a second surface that is opposite to the first surface, at least one third surface, and a light incident surface. The third surface and the light incident surface are between the first and second surfaces. The third surface is adjacent to the light incident surface and has a concave-convex structure. The light source is located on the light incident surface. When the light source emits light, the light of the light source enters the light guide plate and transmits to the concave-convex structure, such that the light irradiates out from the concave-convex structure due to refraction, and is reflected back to the light guide plate by the concave-convex structure.

Light emitting device and light guide plate thereof

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.

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.
