A backlight module includes a light source, a first prism sheet disposed on the light source, and a light type adjustment sheet disposed on a side of the first prism sheet away from the light source and including a base and multiple light type adjustment structures. The multiple light type adjustment structures are disposed on the first surface of the base. Each light type adjustment structure has a first structure surface and a second structure surface connected to each other. The first structure surface of each light type adjustment structure and the first surface of the base form a first base angle therebetween, and the second structure surface of each light type adjustment structure and the first surface of the base form a second base angle therebetween. The angle of the first base angle is different from the angle of the second base angle.

Backlight module

A light source module includes a substrate, a reflective sheet, a plurality of light-emitting elements, an adhesive layer, and a frame. The reflective sheet is disposed on the substrate and has a side wall, a protrusion and a plurality of openings. The protrusion is protruded in a direction away from the substrate and has a mesh structure to define a plurality of dimming areas. The plurality of openings respectively correspond to the plurality of dimming areas. The plurality of light-emitting elements are disposed on the substrate, and the plurality of light-emitting elements are respectively disposed to pass through the plurality of openings. The adhesive layer is disposed between the substrate and the reflective sheet. The frame surrounds the reflective sheet and the plurality of light-emitting elements. The side wall of the reflective sheet is disposed on the frame. A display device of the invention is further provided.

Light source module and display device

A display apparatus including a display panel and a light source module is provided. The display panel displays an image frame according to a light beam. The light source module provides the light beam to the display panel. The light source module includes a light emitting device, a lens module, a reflection device, and a light emitting surface. The light emitting device provides the light beam. The lens module is disposed in a transmission path of the light beam and adjusts the light beam to be focused or dispersed. The reflection device receives the light beam passing from the lens module and reflects the light beam to the light emitting surface. The lens module includes a lens disposed in the transmission path of the light beam and moves relative to the light emitting device to adjust a viewing angle of the light emitting surface.

Light source module and display apparatus

A light source module includes a substrate, a reflective assembly and a plurality of point light sources. The reflective assembly is disposed above the substrate and has a plurality of first partition plates disposed along a first direction, a plurality of second partition plates disposed along a second direction and a plurality of reflective structures. The first and second partition plates cross with each other to form a plurality of reflective holes. An upper surface of the substrate is partially exposed to the reflective holes. The reflective structures are disposed in the reflective holes respectively. The first partition plates, the second partition plates and the reflective structures are integrally formed. The point light sources are disposed above the substrate, located in the reflective holes respectively, and located below the reflective structures respectively. Thus, the light source module can significantly reduce the light mixing distance.

Array of point light sources contained within segmented reflective partitions

A backlight module includes a light guide plate, a plurality of light transmission elements and a light source. The light guide plate has at least one light incident surface, and the light transmission elements are disposed near the light incident surface and aligned to from at least one light transmission element row. The light source is disposed near one end of the light transmission element row and capable of emitting a light beam to the light transmission element row. Each of the light transmission elements reflects a part of the light beam to the light guide plate to form multiple independent light reflection paths, and the light transmission elements successively transmits a part of the light beam to form a light transmission path in the light transmission element row.
