Embodiment
As shown in figure 1, the VR equipment schematic diagrams provided for the utility model embodiment, including：It is saturating in VR equipment
Mirror, display screen and the microlens array film positioned at the display screen on the surface of human eye side, the lens are located at people
Between eye and the microlens array film.
Wherein, the microlens array film includes basic unit and multiple lenticules, and it is remote that the lenticule is located at the basic unit
In one side from the display screen；N number of lenticule on the pixel correspondence microlens array film of the display screen,
N is the integer more than 1.
The VR equipment that the VR equipment that the utility model embodiment is provided is provided, comprising lens, display screen and positioned at display
Microlens array film of the screen on the surface of human eye side, the microlens array film is by basic unit and multiple lenticule structures
Into, and N number of lenticule on the pixel correspondence microlens array film of display screen so that on display screen in a pixel
Each luminous point by N number of luminous point can be become after N number of lenticule so that covering microlens array film after
The quantity of the luminous point of display screen improves N-1 times, more hence into the luminous point of human eye, can reduce the particle of display image
Sense.
Basic unit on microlens array film be with high index of refraction, high transmittance and the larger film of Abel's coefficient,
Preferably, can be using the convenient plastic sheeting processed, a kind of mode realized is that can use polymethyl methacrylate
Film is made in (Polymethyl Methacrylate, PMMA) material.
The arrangement mode of lenticule on microlens array film and the pixel arrangements of display screen are adapted, for example when
When the pixel of display screen uses honeycomb arrangement mode, then the lenticule on microlens array film is also arranged using honeycomb
Row mode；When the pixel of display screen uses rectangular configuration arrangement mode, then the lenticule on microlens array film is also used
Rectangular configuration arrangement mode, lenticule can be spherical convex lens.
As shown in Fig. 2 a kind of microlens array film of the honeycomb provided for the utility model.
Microlens array film can be that basic unit and multiple lenticules are obtained using roller hot pressing or coating method processing,
First using the standby mould with certain fine structure of high resolution electron beam optical graving, then become polymeric material through hot pressing
Shape, fine structure is gone out in its surface imprint, and coating process mainly carries out gluing coating using reticulate pattern (celophthalmia) applicator roll, and it is applied
Cloth is uniform, and coating weight is more accurate, when being coated with anilox roll, the celophthalmia depth and glue kind of coating weight mainly with anilox roll
The precision of class is relevant.
After microlens array film is made, by the film is seamless, the dustless table for being fitted in display screen close to human eye side
It is directionless to require on face, cover whole display screen.
After the microlens array film, after R, G, B sub-pixel for emitting light point imaging of each pixel on display screen,
Due to the N number of lenticule of each sub-pixel for emitting light point correspondence, so that after each sub-pixel for emitting light point passes through N number of lenticule,
Become N number of luminous point, i.e., for whole display screen, it is assumed that itself luminous is counted out as M, then by microlens array
After film, luminous point is changed into M*N, thus improves the luminous point quantity into human eye, it is possible to decrease the granular sensation of screen.
Certainly, because the depth of field of VR lens is limited, if the radius of curvature of lenticule is excessive, (i.e. each sub-pixel is corresponding
The quantity N of lenticule is than larger), it can largely reduce the definition of picture；Too small (the i.e. each sub-pixel correspondence of radius of curvature
Lenticule quantity N it is smaller), and by the distance of display screen to lens influenceed cause reduce granular sensation effect it is on the weak side, because
