Abstract
The invention discloses a method for reducing moire fringes of an autostereoscopic display with a lenticular grating. A layer of anti-glare structure is processed and formed on the rear surface of the lenticular grating, and the anti-glare structure comprises a lot of microcosmic small lenses. The anti-glare structure comprising a lot of microcosmic small lenses can effectively reduce the moire fringes generated by the lenticular grating and a liquid crystal display screen, and can reduce at most 70% of the generated moire fringes on the premise of not influencing the display effect of the autostereoscopic display with the lenticular grating.
Description
Technical field
The invention belongs to the free 3 D display technology field, particularly a kind of method that reduces the auto-stereoscopic display Moire fringe.
Background technology
Moire fringe is the visual phenomenon of interfering with constant angle and Frequency generated between two lines or two objects, and it makes human eye can't differentiate these two lines or two objects, can only see the striped of interference.In the column mirror grating auto-stereoscopic display, because the pixel of 2D display is the periodicity matrix structure of ordered arrangement, its light field of sending also has periodically matrix structure, the column mirror grating of the periodic structure of such light field and 2D display screen front is interfered mutually, form Moire fringe, wherein, the black matrix of periodic arrangement and column mirror grating constructive interference generate the black and white Moire fringe between 2D display screen sub-pixel, the R of periodic arrangement, G, B sub-pixel color filter and column mirror grating constructive interference generate colored Moire fringe, make bore hole 3D display effect variation, even cause image normally to show.
Summary of the invention
The purpose of this invention is to provide a kind of method that can effectively reduce the auto-stereoscopic display Moire fringe.
For achieving the above object the technical solution used in the present invention:
A kind of method that reduces column mirror grating auto-stereoscopic display Moire fringe is processed to form one deck glare prevention structure at the column mirror grating backside surface, and described glare prevention structure is to be made of many microcosmic lenslets.
The roughness of described glare prevention structure is 0.1 μ m～3.00 μ m.
The roughness of described glare prevention structure is 0.1 μ m～0.6 μ m.
Described column mirror grating can be glass column mirror grating or plastic grating.
Described glare prevention structure is by glass acid etching or plated film or pad pasting is compound or the gel spraying forms.
The present invention is by being processed to form one deck glare prevention structure at the column mirror grating backside surface, and this layer glare prevention structure is made of many microcosmic lenslets, can be effectively with mirror-reflection light scattering, namely diffuse reflection.In like manner, glare prevention structure is applied to column mirror grating, the light that sends from the 2D display screen reflects by column mirror grating first, again by glare prevention structure, and part light generation scattering, thus can effectively reduce Moire fringe.This method technique is simple, can effectively reduce the Moire fringe that occurs in the auto-stereoscopic display, and the loss of the spectrophotometric result of column mirror grating is few, under the prerequisite that does not affect column mirror grating auto-stereoscopic display display effect, the Moire fringe that produces that can the highest minimizing 70%, do not affect the 3D display effect, make bore hole 3D TV more clear.
Embodiment
A kind of method that reduces column mirror grating auto-stereoscopic display Moire fringe, be processed to form one deck glare prevention structure at the column mirror grating backside surface, glare prevention structure is to be made of many microcosmic lenslets, the roughness of glare prevention structure is 0.1 μ m～3.00 μ m, column mirror grating can be glass column mirror grating or plastic grating, also can use other grating materials.Glare prevention structure is by glass acid etching or plated film or pad pasting is compound or the gel spraying forms.
Below with specific embodiment technical scheme of the present invention is described:
Embodiment 1

Embodiment 4
Column mirror grating, liquid crystal display and column mirror grating are consistent with embodiment 1 to parameters such as liquid crystal display distances.
Glare prevention structure is the many microcosmic lenslets that are compounded to form by pad pasting, glare prevention structure roughness: 0.99 μ m
Adopt the Moire fringe identifier to test test result: Moire fringe reduces 90%, and column mirror grating divides photosensitiveness loss 30%
Among the present invention, along with the change of glare prevention structure roughness is large, Moire fringe reduces, column mirror grating divides the photosensitiveness loss to increase, the glare prevention structure roughness does not affect column mirror grating auto-stereoscopic display display effect in 0.1 μ m～0.6 μ m scope, the Moire fringe that produces that can the highest minimizing 70%, do not affect the 3D display effect, make bore hole 3D TV more clear.
