Refer to Fig. 2 to Fig. 4, the present embodiment provides a kind of optical texture 4, including: beam splitter
Part 41 and microlens structure 42, microlens structure 42 is positioned at the top of light-splitting device 41；Micro-
Mirror structure 42 forms collimated light for ambient light carries out collimationization process, so that collimated light hangs down
Direct projection is to light-splitting device 41；Light-splitting device 41 is used for being divided into collimated light the monochromatic light of multiple color,
And by the colored color blocking 121 of same color in the monochromatic light directed color membrane substrates 1 of each color.
Why it is arranged such, is owing to the direction of ambient light can be changed by microlens structure 42
Become, form collimated light and make collimated light vertical directive light-splitting device 41, as in figure 2 it is shown, so
Collimated light just can be made will not to be filtered when polaroid 3 and can be all by (or only
Filtered sub-fraction), thus add the intensity of the light by polaroid 3；By setting
Put light-splitting device 41, direct light (colour mixture light) can be directed at and separate, collimated light is divided into many
The monochromatic light of kind of color, thus avoid collimated light when through color film layer 12, the intensity of light
Weakened.It is to say, by arranging light-splitting device 41 and microlens structure 42, can avoid
Collimated light loss when through the color film layer 12 of polaroid 3 and display base plate, thus improve logical

When being arranged on lenticule support member 422, it is not to be uniformly distributed, but meets certain dividing
Cloth condition, the incident direction of i.e. every beam ring environmental light and this beam ring environmental light are at sub-lenticule 421
On incidence point tangential direction (shown in dotted line) between the angle of angle α identical, therefore,
The situation that stacking is placed can be there is, by the heap of finite element in many sub-lenticulees 421 when arranging
Folded mode can form cellular microlens structure 42.
Wherein, light-splitting device 41 is binary optical elements or prism.If it is understood that dividing
Optical device 41 uses binary optical elements, then utilize diffraction principle that collimated light is divided into monochromatic light；
If light-splitting device 41 uses prism, then utilize refraction principle that collimated light is divided into monochromatic light.Certainly,
Light-splitting device 41 can also be other kinds of optics, as long as can be by environment colour mixture light
It is divided into multiple monochromatic light, does not repeats them here.
The optical texture of the present embodiment, including: light-splitting device 41 and microlens structure 42, micro-
Lens arrangement 42 is positioned at the top of light-splitting device 41, by arranging microlens structure 42, it is possible to
