Abstract
The utility model discloses a 2D3D switches display device, because the side of the light -emitting at a liquid crystal display panel is provided with the 2nd the liquid crystal display panel, because when a liquid crystal display panel showed for 3D, the 2nd the liquid crystal display panel was complete printing opacity, so the 2nd the liquid crystal display panel's setting can not influence the effect that 3D shows. But when 2D shows, because the the liquid crystal molecules in the 2nd liquid crystal display face is no regular spread, because the liquid crystal molecules's birefringence characteristic, the light that results in a liquid crystal display panel outgoing produces strong scattering during through the the liquid crystal molecules in the 2nd the liquid crystal display panel's the liquid crystal layer, thereby the light to a liquid crystal display panel outgoing carries out the scattering, make left eye and right side eye can see the image information of all pixels among the the liquid crystal display panel simultaneously, thereby realize the full resolution when 2D shows, the problem of among the prior art resolution ratio reduce by half is solved.
