Disparity barrier formula naked-eye stereoscopic display generally realizes that with liquid crystal grating 2D/3D is changeable.Because there is angular field of view in liquid crystal grating, just can see stereoeffect when the grating contrast is big in angular field of view.Existing liquid crystal grating three-dimensional display when observing than wide-angle, because the grating poor contrast can't be separated the right and left eyes image fully, ghost image, the unfavorable problem of stereoeffect occur easily.
Summary of the invention
The three-dimensional display that the purpose of the embodiment of the invention is that a kind of two-sided compensation polaroid is provided and adopts this polaroid is intended to solve existing liquid crystal grating three-dimensional display because the grating visual angle is little, the wide-angle poor contrast causes some viewed to can't see the problem of stereoeffect or stereoeffect difference easily.
The embodiment of the invention is achieved in that a kind of polaroid, and said polaroid comprises polarizing layer, over against the surface coverage of grating first compensate film is arranged at said polarizing layer, over against the surface coverage of display screen second compensate film is arranged at said polarizing layer.
Another purpose of the embodiment of the invention is to provide a kind of three-dimensional display; Said three-dimensional display comprise display screen, grating and be arranged at display screen and grating between first polaroid; Said first polaroid comprises polarizing layer; Over against the surface coverage of grating first compensate film is arranged at said polarizing layer, over against the surface coverage of display screen second compensate film is arranged at said polarizing layer.
In an embodiment of the present invention, through on the two sides of first polaroid between display screen and the grating, layer of compensation being set, one side is used for the display screen viewing angle compensation, and another side is used for the grating viewing angle compensation.Two sides compensate film draw direction (compensation way) is identical or different.When this first polaroid is used for three-dimensional display; Wide visual angle grating is in scope with great visual angle; The grating contrast is all big, can play fine parallax barrier, make human eye watch more how three-dimensional viewpoint right in larger scope, thus expansion three-dimensional display 3D observation visual angle scope.
