Technical solution for a better understanding of the present invention, below to above-mentioned display device provided in an embodiment of the present invention,
The process that dark-state is shown, illuminated state is shown is carried out respectively under peep-proof mode and shared model to describe in detail.
When being shown Fig. 2 shows dark-state under peep-proof mode, the status diagram of liquid crystal molecule in liquid crystal layer 106.Specifically,
When dark-state is shown under peep-proof mode, without driving and load on the first plane-shape electrode 1071, it is in floating (Floating) state, the
Public (Vcom) voltage is loaded on two plane-shape electrodes 1073, loads pixel on each strip shaped electric poles in third electrode layer 1075
(Pixel) voltage, and public (Vcom) voltage is identical as pixel (Pixel) voltage swing, so that liquid crystal molecule in liquid crystal layer 106
Orientation keep initial orientation, the i.e. vertical paper of long axis of liquid crystal molecule, and long axis of liquid crystal molecule direction and the first polarizing film 108
Light transmission axis direction is parallel to each other, and therefore, liquid crystal molecule will not change the polarization state of incident ray, and incident ray is by the first polarizing film
108 absorb, and realize that dark-state is shown.
When Fig. 4 shows illuminated state display under peep-proof mode, the status diagram of liquid crystal molecule in liquid crystal layer 106.Specifically,
When illuminated state is shown under peep-proof mode, without driving and load on the first plane-shape electrode 1071, it is in floating (Floating) state, the
Public (Vcom) voltage is loaded on two plane-shape electrodes 1073, loads pixel on each strip shaped electric poles in third electrode layer 1075
(Pixel) voltage, and public (Vcom) voltage is different from pixel (Pixel) voltage swing；And because of the thickness of liquid crystal layer 106 (6 μ
M-10 μm) than in the prior art the thickness of liquid crystal cell (3.5 μm) it is big, period (the i.e. two neighboring strip shaped electric poles of each strip shaped electric poles
The distance between center be 1 μm -5 μm) than in the prior art the period (7 μm) of each strip shaped electric poles it is small so that in liquid crystal layer 106
Close on optical grating construction 1072 liquid crystal molecule will not by the electric field driven between the second plane-shape electrode 1073 and each strip shaped electric poles, and
Close on the liquid crystal molecule of third electrode layer 1075 by the electric field driven between the second plane-shape electrode 1073 and each strip shaped electric poles, along
Electric field line direction rotates, and rotation mode in face similar to rotating, to change the polarization state of incident ray, first is polarized
Piece 108 can realize that illuminated state is shown with transmitted ray.
Seen from the above description, under peep-proof mode, by controlling the first plane-shape electrode 1071, the second plane-shape electrode 1073
With the voltage-drop loading situation of strip shaped electric poles each in third electrode layer 1075, the display of 0-255 grayscale may be implemented, to meet anti-
Peep the normal display function under mode.Specifically, Fig. 5 show simulated conditions be liquid crystal layer 106 (i.e. liquid crystal cell) with a thickness of
10 μm, grating structure period (the distance between i.e. two neighboring convex center L) is 5 μm, and the high H of arch protrusion is 1 μm, liquid crystal point
Son is 1.8 to the refractive index ne phase of extraordinary ray, liquid crystal molecule to ordinary refraction index no be 1.5 display device in peep-proof mould
Gray scale curve under formula.
When Fig. 6 shows dark-state display under shared model, the status diagram of liquid crystal molecule in liquid crystal layer 106.Specifically,
When dark-state is shown under shared model, certain driving signal V1, the second plane-shape electrode 1073 are loaded on the first plane-shape electrode 1071
It is upper to load public (Vcom) voltage, pixel (Pixel) voltage is loaded on each strip shaped electric poles in third electrode layer 1075, and public
(Vcom) voltage is identical as pixel (Pixel) voltage swing.In liquid crystal layer 106 liquid crystal molecule by the first plane-shape electrode 1071 with
In third electrode layer 1075 between each strip shaped electric poles vertical electric field driving, show erected state, at this time liquid-crystal refractive-index with
The refractive index of optical grating construction 1072 is different, and optical grating construction 1072 breaks up the direction of propagation of incident ray, realizes shared display, so
And since liquid crystal molecule does not change the polarization state of incident ray, so incident ray is absorbed by the first polarizing film 108, realize dark
State is shown.
When Fig. 7 shows illuminated state display under shared model, the status diagram of liquid crystal molecule in liquid crystal layer 106.Specifically,
When illuminated state is shown under shared model, certain driving signal V1, the second plane-shape electrode 1073 are loaded on the first plane-shape electrode 1071
It is upper to load public (Vcom) voltage, pixel (Pixel) voltage is loaded on each strip shaped electric poles in third electrode layer 1075, and public
(Vcom) voltage is different from pixel (Pixel) voltage swing, so that the liquid crystal molecule in liquid crystal layer 106 is by the first plane-shape electrode
1071 and third electrode layer 1075 between each strip shaped electric poles vertical electric field driving, show erected state, liquid crystal is rolled at this time
Penetrate that rate is different from the refractive index of optical grating construction 1072, optical grating construction 1072 breaks up the direction of propagation of incident ray, realizes shared
Display.And because the thickness of the thickness of liquid crystal layer 106 (6 μm -10 μm) liquid crystal cell (3.5 μm) than in the prior art is big, each strip electricity
Period (the distance between center of i.e. two neighboring strip shaped electric poles be 1 μm -5 μm) of pole each strip shaped electric poles than in the prior art
Period (7 μm) is small so that closed in liquid crystal layer 106 optical grating construction 1072 liquid crystal molecule will not by the second plane-shape electrode 1073 with
Electric field driven between each strip shaped electric poles, and close on the liquid crystal molecule of third electrode layer 1075 by the second plane-shape electrode 1073 with it is each
Electric field driven between strip shaped electric poles is rotated along electric field line direction, and rotation mode in face similar to rotating, to change
The polarization state of incident ray, the first polarizing film 108 can realize that the illuminated state under shared model is shown with transmitted ray.
Seen from the above description, in a shared mode, by controlling the first plane-shape electrode 1071, the second plane-shape electrode 1073
With the voltage-drop loading situation of strip shaped electric poles each in third electrode layer 1075, the display of 0-255 grayscale may be implemented, to meet altogether
Enjoy the normal display function under mode.Specifically, Fig. 8 show simulated conditions be liquid crystal layer 106 (i.e. liquid crystal cell) with a thickness of
