As shown in
a liquid crystal panel 100 and a phase difference structure 106 located on a light-exiting side of the liquid crystal panel 100, wherein, the liquid crystal panel 100 comprises an array substrate 103 and a color filter substrate 104 disposed in opposition to each other, and a liquid crystal layer 110 interposed between the array substrate 103 and the color filter substrate 104, a plurality of patterned phase difference diaphragms 107 are arranged on the phase difference structure 106.
Herein, a plurality of light-shielding strips 201 are disposed on a side of the array substrate 103 far away from the liquid crystal layer, and orthographic projections of the plurality of light-shielding strips 201 on the phase difference structure 106 cover boundary lines of the patterned phase difference diaphragms 107 on the phase difference structure 106; a plurality of black matrix strips 108 are disposed on a side of the color filter substrate 104 facing the array substrate 103, and orthographic projections of the plurality of black matrix strips 108 on the phase difference structure 106 cover boundary lines of patterned phase difference diaphragms 107 on the phase difference structure 106.
The light-shielding strips 201 are disposed on a side of the array substrate 103 facing a first polarizer 102, a plurality of black matrix strips 108 are disposed on a side of the color filter substrate 104 facing the array substrate 103, and orthographic projections of the plurality of light-shielding strips 201 and the plurality of black matrix strips 108 on the phase difference structure 106 cover boundary lines of the patterned phase difference diaphragms 107 on the phase difference structure 106. Under the combined action of shielding of the light-shielding strips 201 and the black matrix strips 108, a viewing angle at which no optical interference occurs between adjacent pixels of the polarization-type three-dimensional display device is increased, and furthermore, aperture ratio of each pixel can be guaranteed.
According to an embodiment of the invention, there is provided a polarization-type three-dimensional display device, capable of increasing a vertical viewing angle of the polarization-type three-dimensional display device.
As shown in
The light-shielding strips 201 are disposed on a side of the array substrate 103 facing the first polarizer 102, the plurality of black matrix strips 108 are disposed on a side of the color filter substrate 104 facing the array substrate 103, and orthographic projections of the plurality of light-shielding strips 201 and the plurality of black matrix strips 108 on the phase difference structure 106 cover boundary lines of the patterned phase difference diaphragms 107 on the phase difference structure 106. Under the action of shielding of the light-shielding strips 201 and the black matrix strips 108, a viewing angle at which no optical interference occurs between adjacent pixels of the polarization-type three-dimensional display device is increased, and furthermore, the aperture ratio of each pixel can be guaranteed.
Exemplarily, in the case that a larger aperture ratio is required, projections of the light-shielding strips 201 on the phase difference structure 106 may be covered by projections of the black matrix strips 108 on the phase difference structure 106.
Exemplarily, orthographic projections of the light-shielding strip 201 and the black matrix strip 108 on the phase difference structure 106 may coincide, so that the maximum vertical viewing angle can be achieved while the aperture ratio can be guaranteed.
In practical applications, in order to simplify the manufacturing process, it is possible to let the light-shielding strips 201 and the black matrix strips 108 have the same size and shape.
Of course, those skilled in the art may adopt other feasible ways to set the light-shielding strips 201 as well, only one exemplary implementation is provided here, and they will not be described any more one by one.
In practical applications, material for the light-shielding strips 201 may be metal or an acrylic polymer. Exemplarily, metal may be selected for production of the light-shielding strips 201, so as to reduce the resistivity of the whole back face of the array substrate 103, and serve a better function of electrostatic shielding, and furthermore, the flatness of surface for the light-shielding strip 201 made of the metal is better than the flatness of surface for the light-shielding strip 201 made of the acrylic polymer.
Of course, those skilled in the art may adopt other available light-shielding materials to make the light-shielding strips 201, only one exemplary material is provided here, and they will not be described any more one by one.
Further, in order to make the vertical viewing angle of each pixel uniform, it is possible to let the light-shielding strips 201 have the same shape. Further, it is possible to let the orthographic projection of the light-shielding strip 201 on the phase difference structure 106 be symmetric with a boundary line of the patterned phase difference diaphragms 107 that is covered by it, so that the vertical viewing angle of each pixel is uniform.
Further, it is also possible to let the orthographic projection of the black matrix strip 108 on the phase difference structure 106 be symmetric with a boundary line of the patterned phase difference diaphragms that is covered by it. Thereby, this facilitates settings of the polarization-type three-dimensional display device, and it is easier to make the vertical viewing angle of each pixel of the polarization-type three-dimensional display device be more uniform.
In order to simplify the manufacturing process, it is possible to dispose the light-shielding strips 201 on a side of a base substrate of the array substrate 103 facing the first polarizer 102.
Optionally, according to an embodiment of the invention, there is provided a polarization-type three-dimensional display device, as shown in
The vertical viewing angle of the polarization-type three-dimensional display device shown in
The wider the width of the light-shielding strip 201 in a direction perpendicular to an interface of the phase difference structure 106 (namely, the width of the light-shielding strip 201) is, the larger the vertical viewing angle of the polarization-type three-dimensional display device is. However, if the width of the light-shielding strip 201 in the direction perpendicular to the interface of the phase difference structure 106 is wide excessively, the aperture ratio of each pixel may be adversely affected. Therefore, in order to achieve increasing of the vertical viewing angle of a polarization-type three-dimensional display device to the maximum degree while reduction in the aperture ratio of each pixel resulting from arrangement of light-shielding strips 201 is avoided, it is possible to let orthographic projections of the light-shielding strip 201 and the black matrix strip 108 on the phase difference structure 106 coincide.

Under the action of shielding of the light-shielding strips and the black matrix strips, it allows 2arc tan (h/d)>2arc tan (h/D)>2arc tan (h/2D). Thereby, a viewing angle at which no optical interference occurs between adjacent pixels of the polarization-type three-dimensional display device is increased while the aperture ratio is guaranteed. In turn, a vertical viewing angle of the polarization-type three-dimensional display device is increased.
