摘要： There are provided a light source device and a display device, in which the contact of the light guiding plate with the light source can be prevented. The light source device includes a light guiding plate and a light source member disposed opposite to a light-entering surface of the light guiding plate, wherein light radiated by the light source enters from the light-entering surface and emits from a light-emitting surface of the light guiding plate. The light source device further includes a frame structure and a heat radiator supporting the light source member, wherein the frame structure includes a contact-preventing part disposed between the substrate of the light source member and the light-entering surface to prevent the contact of the light-entering surface with the light source, and portions of the heat radiator and the contact-preventing part each facing the light source have light reflectivity.

摘要： A two-dimensional/three-dimensional (2D/3D) switchable display backlight and a 2D/3D switchable electronic display employ a switchable diffuser to support 2D/3D switching. The 2D/3D switchable display backlight includes a plate light guide, a multibeam diffraction grating to couple light out of the plate light guide and the switchable diffuser to intercept and selectably either pass or scatter light beams of the coupled-out light. The 2D/3D switchable electronic display includes the backlight and further includes a light valve array to modulate the coupled-out light. The switchable diffuser facilitates selectability between a three-dimensional pixel and a two-dimensional pixel of the 2D/3D switchable electronic display.
