Embodiment
Attached drawing is specific embodiment of the utility model.As shown in Fig. 1 to Figure 14, this kind of multi-functional continuous visual angle is controllable aobvious
Show device, including the polarizer 1, wide viewing angle display module 2, blue phase liquid crystal box 3 and the analyzer 4 being arranged in order, the arrow table in Fig. 1
Show the direction of propagation of light, as shown in Fig. 2, blue phase liquid crystal box 3 includes one piece of infrabasal plate 5 and one piece of upper substrate 8, upper substrate 8 is with
Substrate 5 is parallel, and upper substrate 8 and infrabasal plate 5 are all an entire panels, are connected between upper substrate 8 and infrabasal plate 5 by frame glue 7, blue
Phase liquid crystal 9 is between upper substrate 8 and infrabasal plate 5, and the top of infrabasal plate 5 is lower transparency electrode 6, and lower transparency electrode 6 is a monoblock
Panel shape, the lower section of upper substrate 8 is some upper transparency electrodes 10 being equally spaced；As Fig. 3 can also be under upper transparency electrode 10
Side sets insulating layer 12, the 12 interior transparency electrode 11 to equidistantly distribute of insulating layer lower section, interior transparency electrode 11 and upper transparent electricity
Pole 10 is arranged at intervals.
Operation principle is as follows：As shown in Figure 2 and Figure 3, blue phase liquid crystal lenticule works required ordinary index of refraction no with electricity
The principle of field change changes electrode voltage, can make the refractive index of the blue phase liquid crystal of diverse location in blue phase liquid crystal box come what is realized
No is different, rational coordination electrode voltage, you can realize the function of lens.The wherein section signal of Fig. 2 and Fig. 3 liquid crystal lens box
Figure, upper substrate transparency electrode is is respectively single-layer electrodes bar and two-layer electrode bar, such as V3=0 in Fig. 2, V2=V4<V1=V5 is formed
Lens function, such as V6=0 in Fig. 3, V5=V7<V4=V8< V3=V9<V2=V10<V1=V11 forms lens function.
Since blue phase liquid crystal lens have tunability, the effect of the non-lens of uniformity arrangement can also be driven into,
Control visual angle width change is realized using the exclusive viewing angle characteristic of liquid crystal.Bore hole stereoscopic display module composition easy structure such as Fig. 1
Shown, blue phase liquid crystal box realizes the function at continuous viewing angle control visual angle, and the light transmission shaft of analyzer and the polarizer is according to wide light visual angle
The operation principle of module is designed to that orthogonal or parallel collocation uses, such as analyzer light transmission shaft azimuth for 0 degree with being polarized
The light transmission shaft azimuth of device is 90 degree, or analyzer light transmission shaft azimuth is 90 degree and the light transmission shaft azimuth of the polarizer is 0
Degree.Wide viewing angle display module can be that liquid crystal display is arranged in pairs or groups the high performance wide viewing angle module to be formed with compensation film, blue phase liquid crystal
Box internal structure can be designed to different structures, such as liquid crystal lens as needed
As shown in Figure 2 and Figure 3, wherein lower transparency electrode is whole face electrode, when blue phase liquid crystal is driven into the row of vertical substrate
During the uniaxial crystal of row, with the increase of voltage, the refractive index anisotropic △ n of liquid crystal increase therewith, by controlling power-on and power-off
Pole tension realizes that visual angle is continuously controllable, but azimuth is 0 degree, and 90 degree, 180 degree, 270 degree of direction remains as wide viewing angle,
Cannot play the function of secret protection well, Fig. 5 be when not applying electric field wide viewing angle etc. contrast distribution analogous diagram, Fig. 6
For apply electric field when visual angle narrow etc. contrast distribution analogous diagram.
As shown in figure 4, when the liquid crystal of uniaxial positive be tilted to the right in xoz planes or face parallel to the plane it is certain
During angle, it may appear that the contrast viewing angle distribution such as shown in Figure 5, as shown in fig. 6, when the liquid crystal of uniaxial positive is in xoz planes
Or parallel to be tilted to the left in the face of the plane certain angle when, it may appear that viewing angle distribution as shown in Figure 7, mainly due to
Xoz planes or parallel to bit phase delay will not be produced in the face of the plane.And in yoz planes or the face parallel to the plane
Interior generation bit phase delay, it is 90 degree to make azimuth, and the visual angle in 270 degree of direction narrows.
As shown in figure 8, when forming one group or multigroup two domain structure within one lens cycle of blue phase liquid crystal box array,
As shown in figure 9, forming symmetrical viewing angle distribution, narrow viewing angle mode continuous can be achieved in adjustment electrode voltage can for the distribution meeting at visual angle
Control, adjusts voltage and reaches required optimum state as needed.
When blue phase liquid crystal lens do not work, the blue phase liquid crystal of isotropic state is distributed not the LCD display view angles of wide viewing angle
Have an impact, thus can realize wide viewing angle, wide viewing angle contrast distribution is as shown in Figure 10, when liquid crystal lens are operated in double farmlands state
It is continuously controllable that symmetrical narrow viewing angle can be achieved.
In Fig. 8, when coordination electrode voltage forms double domain structures, the change at visual angle is as shown in figures 10-14, electric when pressure difference increases
