Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on embodiment of the present utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection domain of the present utility model.
Embodiment
The schematic diagram of the switchable integration imaging 3 d display device of a kind of 2D/3D that Fig. 1 provides for the utility model embodiment.As shown in Figure 1, it mainly comprises: the back light unit 00 set gradually, optical light guiding plate of side 01, through mode display panel 03, and the switch control unit 04 be connected with described back light unit 00 and optical light guiding plate of side 01 respectively; Wherein, the bottom surface of described optical light guiding plate of side 01 is scattering point array structure, and the both sides of described optical light guiding plate of side 01 are also provided with side entering type light source 02.
Described back light unit 00, for generation of the backlight supporting 2D display; Described optical light guiding plate of side 01, for generation of the pointolite array supporting 3D display; Described switch control unit 04, for switching the open and close state controlling back light unit and optical light guiding plate of side, makes each moment only open back light unit or optical light guiding plate of side; Described through mode display panel 03, shows corresponding 2D or 3D rendering for controlling result according to the switching of switch control unit.
Its principle of work see accompanying drawing 2 and accompanying drawing 4, can represent the principle schematic under 3D display mode and 2D display mode respectively.
As shown in Figure 2:
1, back light unit 20 can be flat panel backlight, and its light source can be light emitting diode, and even smooth mode can add diffusion sheet for light guide plate.
