Abstract: 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.

Abstract: 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.

Abstract: 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 are staggered 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.
