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.

Abstract: A viewing angle switchable display apparatus including a display panel, an electrically controlled viewing angle switching device, an electrically controlled light scattering switching device, and a backlight module is provided. The electrically controlled viewing angle switching device includes two first transparent substrates, two first transparent conductive layers, a liquid crystal layer, and a first polarizer located on a side of the electrically controlled viewing angle switching device which is far away from the display panel. The liquid crystal layer includes liquid crystal molecules, and optical axes of the liquid crystal molecules are parallel or perpendicular to a transmission axis of the first polarizer. The electrically controlled light scattering switching device is located between the display panel and the backlight module and includes two second transparent substrates, two second transparent conductive layers, and an electronically controlled polymer material layer.
