The emergent light of described sprite I is successively through reconstructing 2D scene I after sub-polaroid I and sub-polaroid III, wherein, The polarization direction of the emergent light after sub-polaroid I is identical with the polarization direction of sub-polaroid I；The outgoing of described sprite II Light reconstructs 2D scene II through after sub-polaroid II and sub-polaroid IV successively, the emergent light after sub-polaroid II inclined The direction that shakes is identical with the polarization direction of sub-polaroid II；And the left and right both direction in 2D display device presents vision area I respectively With vision area II, two different 2D scenes can be watched in two vision areas.

As preferred version of the present utility model, described display screen is LCDs, plasma panel and Organic Electricity One of photoluminescence display screen.

As preferred version of the present utility model, being smaller in size than or equal to described sub-polaroid I of described sprite I Size, the size being smaller in size than or being equal to described sub-polaroid II of described sprite II.

As preferred version of the present utility model, being smaller in size than or equal to described sub-polaroid of described sub-polaroid I The size of III, the size being smaller in size than or being equal to described sub-polaroid IV of described sub-polaroid II.

In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: use based on polaroid Integration imaging double vision 2D display device, including for showing the display screen of 2D picture, the first polaroid and the second polaroid, real Having showed double vision 2D to show, described 2D picture emergent light rebuilds 2D scene, knot after sequentially passing through the first polaroid and the second polaroid Structure is simple, low cost, and imaging picture is clear, without film flicker, interference fringe.

Detailed description of the invention

Below in conjunction with the accompanying drawings, this utility model is described in detail.

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain this Utility model, is not used to limit this utility model.

As it is shown in figure 1, a kind of double vision 2D display device based on polaroid, including the display screen for showing 2D picture, First polaroid and the second polaroid, described first polaroid and the second polaroid are set in parallel in the same of described display screen successively Side.

As shown in Figure 4, described 2D picture includes sprite I and sprite II, described sprite I and sprite II position respectively Both sides in display screen；

As in figure 2 it is shown, described first polaroid includes sub-polaroid I and sub-polaroid II, described sub-polaroid I and son are inclined Sheet II polarization direction that shakes is orthogonal, and close-packed arrays in the horizontal direction；
