The contrast of showing device 300 is a × b, and contrast greatly promotes.It illustrates and refers to the following table 1, table 1 is the first liquid crystal cell, second
The contrast numerical tabular of liquid crystal cell and display panel, the white state transmitance of the first liquid crystal cell 1 are 6%, and black state transmitance is
0.006%, so contrast=6%:0.006%=1000:1 of the first liquid crystal cell 1, and the white state of the second liquid crystal cell 2 penetrates
Rate is 90%, and black state transmitance is 5%, so contrast=90%:5%=18:1 of the second liquid crystal cell 2, then final display
The contrast of device be the first liquid crystal cell 1 contrast and the second liquid crystal cell contrast product be equal to 18000:1, the present invention in
By reducing black state transmitance contrast is significantly improved, the contrast of display panel 100 is the first liquid crystal cell 1 in the present invention
18 times of contrast, contrast greatly improves, and this display panel improves contrast while keeping high brightness, and at this time second
Liquid crystal cell does not need polaroid, and mould group integral thickness is relatively thin, and molding process reduces the technique for pasting polaroid together, and technique is simpler
It is single.
Table 1 is the contrast numerical tabular of the first liquid crystal cell, the second liquid crystal cell and display panel
| Project | First liquid crystal cell | Second liquid crystal cell | Display panel |
| White state transmitance | 6% | 90% | 5.40% |

| Contrast | 1000:1 | 18:1 | 18000:1 |
Optionally, the first liquid crystal cell 1 is fit together with the second liquid crystal cell 2 by OCA glue, because of high molecular polymerization thing liquid
Brilliant (PDLC) itself has scattering properties, while cooperating haze OCA glue that shuangping san (the first liquid crystal cell 1 can be effectively controlled
With the second liquid crystal cell 2) moire fringes problem.
Display device of the invention, at least has the advantages that
Display device 300 of the invention is by the way that in the first liquid crystal cell 1, close to the side of backlight module 200, setting has high score
Second liquid crystal cell 2 of sub- polymer liquid crystal or polymer network liquid crystal, in illuminated state, the first liquid crystal cell 1 and the second liquid crystal cell 2 are same
When be in maximum transmission state, in dark-state, the first liquid crystal cell 1 and the second liquid crystal cell 2 simultaneously in minimum transmitance state,
The contrast of final display device is the product of the contrast of the first liquid crystal cell 1 and the contrast of the second liquid crystal cell 2, black by reducing
State transmitance significantly improves contrast.

Equally when orthographic projection of two the first pixel units 123 on backlight module and second pixel unit 223 exist
Orthographic projection on backlight module has orthographic projection of overlapping or three the first pixel units 123 on backlight module and one the
Orthographic projection of two pixel units 223 on backlight module have it is overlapping, at this time due to the area of the second pixel unit 223 be greater than first
The area of pixel unit, it is possible to solve the problems, such as the contraposition deviation of two liquid crystal cells.It should be noted that when two first
Orthographic projection of the pixel unit 123 on backlight module and orthographic projection of second pixel unit 223 on backlight module have friendship
When folded, wherein the frontal projected area of second sub-pixel 224 is greater than in the first pixel unit 123 the in the second pixel unit 223
The frontal projected area of one sub-pixel 124, it is possible to solve the problems, such as contraposition deviation, concrete principle is as above, and which is not described herein again.
Similarly orthographic projection of three the first pixel units 123 on backlight module and second pixel unit 223 are on backlight module
Orthographic projection have overlapping the problem of being equally able to solve contraposition deviation.
