Light area aperture opening ratio is 50%.
In order to illustrate human eye viewing freedom, need to calculate different directions visible space, as shown in Figure 8.With
Illustrate the direction x/y/z visible space for the 3D display device of 13.3inch, 8K, BV3, wherein the direction x is human eye relative to screen
The direction moved left and right, the direction y are the direction that moves up and down relative to screen of human eye, and the direction z is human eye close to or far from screen
The direction of curtain.Wherein, x calculates schematic diagram as shown in figure 9, calculating step is to visible space：Viewing ratio is determined first；
Then human eye horizontal direction movable distance, i.e. A1A2/A3A4 length are determined；By display screen AA area edge sub-pixel light deflection
Angle determines visible space.Due to human eye along y or z to x when moving, can be converted into mobile component, therefore y/z is to visual sky
Between calculate can be converted into x to visible space calculate.
As shown in Figure 10, corresponding due to no longer meeting human eye, grating, 2D panel when human eye is moved along x or the direction y or z
Hiding relation makes other view informations enter human eye, crosstalk will occurs.Therefore the present invention, which illustrates, makes human eye along x/y/z
Direction can obtain the solution of best 3D effect when moving freely.
It is as shown in figure 11 the 2D display screen of 13.3inch, 8K, BV3, oblique raster is in best viewing location visible space
It calculates relevant parameter and as a result, obtaining the direction x/y/z watches being described as follows for free effect：
X is to free viewing：It is as shown in figure 12 the first grating layer electrode control schematic diagram, it is false under limit process conditions
If ITO electrode width is 2 μm, each screen periods is divided into 25 grades.It is that best viewing location time gate control shows on the left of Figure 12
It is intended to, right side is that human eye moves horizontally and (be moved to right side by left side) counter electrode control schematic diagram.By the way that screen periods are divided
At several shelves, change light transmission zone position when human eye is mobile, can solve the problems, such as that human eye, to crosstalk occurs when moving, guarantees x along x
To free viewing.
Y is to free viewing：When human eye moves and x to can be converted to y to movement when moving along y along grating slope direction
To movement, wherein crosstalk will not be generated along grating slope direction, and x can then generate crosstalk to component.By taking two viewpoints as an example, due to
Pixel arrangement has periodically, as the movement of human eye is able to satisfy demand of the human eye less than 10% crosstalk within each period.
It therefore, is 50% by the transparent area aperture opening ratio of the first grating layer, it is ensured that y is to free viewing.
Z is to free viewing：Change practical placing height by changing liquid-crystal refractive-index.When human eye along z to when moving, can lead to
It crosses change energization situation and changes liquid-crystal refractive-index, and then achieve the effect that placing height is variable, it is ensured that z is to free viewing.
By the moving direction according to human eye and apart from the transparent area aperture opening ratio for changing the first grating layer in the present embodiment
And second grating layer refractive index, realize that 3D display device is freely watched.
