Other details.
A kind of lens subassembly is present embodiments provided, applied to 3D display device.Refering to Fig. 2 and Fig. 3, the lens subassembly
100 include microlens array 10, and the microlens array 10 includes transparent substrates 11 and array arrangement in the transparent substrates
Multiple convex lens 12 on 11, wherein, it is provided with lighttight barricade 20 between two convex lenses 12 of arbitrary neighborhood.It needs
It is noted that merely exemplary several convex lenses 12 being shown in which in Fig. 2 and Fig. 3.
Specifically, the material of the microlens array 10 can be selected to polystyrene (PS), poly-methyl methacrylate
The transparent materials such as ester (PMMA) or photoresist, transparent substrates 11 and convex lens 12 in the microlens array 10 can be passed through
Imprint process or InkJet printing processes prepare the integrally formed structure to be formed.
Specifically, the barricade 20 can be prepared to be formed by light-proof material, preferably select to be prepared by light absorbent
It is formed.The light-proof material that the barricade 20 can also be selected to non-extinction prepares to be formed, then in the table of the barricade 20
Face is coated with light absorbent.Wherein, the barricade 20 can be connected to by way of paste in the transparent substrates 11.
In the present embodiment, as shown in Fig. 2, the convex lens 12 is planoconvex spotlight, the side of wherein plane is connected to described
In transparent substrates 11.Further, as shown in figure 3, the edge contour of the convex lens 12 is square, each convex lens 12
Area equation, that is, when the lens subassembly 100 be applied to 3D display device, the pixel that each convex lens 12 is covered
Quantity is equal.
