Background technology
Along with the development of display technique, display is progressive to showing stereopsis (Three dimensional image) from display plane image (Two dimensional image).Fig. 1 is the synoptic diagram of the cylindrical lens array (Lenticular lens array) of existing dimensional image display.Please refer to Fig. 1, this cylindrical lens array 100 is made up of a plurality of cylindrical lens 100A.The incident light L1 that incides each cylindrical lens 100A can be focused on by cylindrical lens 100A, and continues to shine outside the cylindrical lens 100A and become the emergent light L2 that advances in the right both sides of turning left.That is to say that cylindrical lens array 100 can be invested right and left eyes respectively with image light, to reach the stereo display effect.
Yet the fabrication and processing of above-mentioned cylindrical lens 100A is quite difficult, reach predetermined optical precision degree and need spend quite high cost.Moreover the focal length of cylindrical lens 100A is promptly fixing after completing, and can't rechange.The user only can just can observe stereopsis in certain distance range, this causes the restriction of dimensional image display.
Fig. 2 is the synoptic diagram of existing liquid-crystal zoom lens.Please refer to Fig. 2, this liquid-crystal zoom lens 200 comprises: lower glass substrate 210, bottom electrode 220, separation material 230, liquid crystal layer 240, top glass substrate 250 and top electrode 260.
Please continue with reference to Fig. 2, the position of each element is closed and to be, bottom electrode 220 is arranged on the lower glass substrate 210.Separation material 230 is arranged on the bottom electrode 220.Top glass substrate 250 is arranged on the separation material 230.Liquid crystal layer 240 is between bottom electrode 220 and top glass substrate 250.Top electrode 260 is arranged on the top glass substrate 250 and is positioned at two ends, the left and right sides.
It should be noted that top electrode 260 is strip shaped electric poles, bottom electrode 220 is a plane electrode.By such electrode setting mode, can in liquid crystal layer 240, produce non-uniform electric field distribution E.This non-uniform electric field distribution E makes that the degree of deflection (being the phase delay degree) of the liquid crystal molecule (not illustrating) of diverse location is inequality in the liquid crystal layer 240.Therefore, light (not illustrating) is slow and fast by the speed of peripheral part by the speed of the center section of liquid-crystal zoom lens 200, and then makes liquid-crystal zoom lens 200 reach the effect of focusing.
In order to make liquid-crystal zoom lens 200 produce the good focusing effect, certain thickness top glass substrate 250 must be set between top electrode 260 and liquid crystal layer 240.More specifically,, just there are enough distances to make the electric field gradual change between the top electrode 260 of both sides and the bottom electrode 220, and produce non-uniform electric field distribution E as shown in Figure 2 because be provided with certain thickness top glass substrate 250.If top glass substrate 250 is not set, then the distance between the top electrode 260 of bottom electrode 220 and both sides can be too approaching, and at this moment, electric field can concentrate on the both sides of liquid-crystal zoom lens 200, can't form non-uniform electric field distribution E.But,, make that on the contrary thickness increase, complex structure, the processing procedure of liquid-crystal zoom lens 200 is loaded down with trivial details and cost is higher just because top glass substrate 250 must be set.
