Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature.

As shown in fig. 1, an embodiment of the invention provides a display device 100, including: analyzer 102, first liquid crystal cell 110, polarizer 101, second liquid crystal cell 120, and backlight structure 130.
The first liquid crystal cell 110 includes: the liquid crystal display device comprises an array substrate, a liquid crystal layer and a color film substrate.
The array substrate and the color film substrate are arranged oppositely.
The liquid crystal layer is arranged between the array substrate and the color film substrate.
The polarizer 101 is disposed at one side of the first liquid crystal cell 110.
The analyzer 102 is disposed on a side of the first liquid crystal cell 110 away from the polarizer 101.
The second liquid crystal cell 120 is disposed on a side of the polarizer 101 away from the first liquid crystal cell 110.
Wherein the second liquid crystal cell 120 includes: a first substrate 121, a second substrate 123, and a first liquid crystal layer 122.
The first substrate 121 is an array substrate; the second substrate 123 is a color filter substrate without RGB color resistance.
The first liquid crystal layer 122 is disposed between the first substrate 121 and the second substrate 123.
The first liquid crystal layer 122 includes a dye liquid crystal molecular system 1220. The dye liquid crystal molecular system 1220 includes a dichroic dye 1221 and a liquid crystal 1222.
The dichroic pigment 1221 includes a dichroic black dye. The dichroic dye 1221 includes an azo dye and a leek dye.
The dichroic dye 1221 has an absorption axis and absorbs polarized light parallel to the absorption axis. Absorption of red, yellow, blue or all visible light is generally possible.
The liquid crystal 1222 includes liquid crystal molecules (LC), Polymer Network Liquid Crystal (PNLC), or Polymer Dispersed Liquid Crystal (PDLC).
In one embodiment, the backlight structure 130 is disposed on a side of the second liquid crystal cell 120 away from the polarizer 101, and the structure is a direct-type backlight structure 130 (as shown in fig. 1).
In other embodiments, the backlight structure 130 may be disposed at the left end or the right end of the second liquid crystal cell 120, for example: the edge-type backlight structure 130 (shown in fig. 2).
The first substrate 121 of the second liquid crystal cell 120 and the array substrate of the first liquid crystal cell 110 have the same structure, the second substrate 123 of the second liquid crystal cell 120 and the color filter substrate of the first liquid crystal cell 110 have different structures, and the second substrate 123 is a color filter substrate with RGB color resistance.
In one embodiment, as shown in fig. 3, the second liquid crystal cell 120 further includes a first electrode 123, a second electrode 125, a first alignment film 124, and a second alignment film 126.
The first electrode 123 is disposed on a side of the liquid crystal layer close to the first substrate 121, and the second electrode 125 is disposed on a side of the first liquid crystal layer 122 close to the first substrate 121.
The first alignment film 124 is disposed between the first substrate 121 and the first electrode 123, and the second alignment film 126 is disposed between the second substrate 123 and the second electrode 125.
The dye liquid crystal molecular system 1220 may be an initially vertically aligned negative liquid crystal, and is horizontally arranged in the second liquid crystal cell 120 by an electric field.
The dye liquid crystal molecular system 1220 may also be an initial horizontally aligned positive liquid crystal that is vertically aligned inside the second liquid crystal cell 120 after power-up. The polarized light parallel to the light absorption axis of the pre-dichroic dye is absorbed to a greater degree, the polarized light in the direction perpendicular to the direction is stored to a greater degree, and when a beam of natural light (non-polarized light) passes through a liquid crystal box (at this time, the liquid crystal is in a dark state) arranged on the dye liquid crystal parallel substrate, the polarized light in the direction parallel to the light absorption axis can be obviously absorbed to become partially polarized light, so that the function of dimming can be realized.
In an embodiment of the present invention, as shown in fig. 4, a dichroic pigment 1221 is added to a liquid crystal layer of a second liquid crystal cell 120 in proportion, and when the second liquid crystal cell 120 is powered on, the dichroic pigment 1221 is aligned along a liquid crystal 1222 direction and exhibits a transparent state; as shown in fig. 5, when the second liquid crystal cell 120 is in the non-transmissive state, the scattered light in the other direction different from the arrangement direction of the dichroic pigments 1221 is absorbed by the dichroic pigments 1221 to take on the black state, thereby functioning as a partition.
This is because due to the addition of the dichroic pigment 1221, in a two-cell (cell) structure as shown in the right drawing, when no power is applied, the dichroic pigment 1221 lies along a plurality of directions of the long axis, and lies along with the liquid crystal 1222, and the scattered light in other directions along the arrangement direction of the dichroic pigment 1221 is absorbed by the dichroic pigment 1221, and the dark state of the second liquid crystal cell 120 is far better than the prior art, which can effectively improve the contrast of the liquid crystal cell.
As shown in fig. 6, another embodiment of the present invention provides a display device 100a, which is different from the embodiment in that the dye liquid crystal molecular system 1220a further includes silicon spheres 1223 a.
The silicon balls 1223a include silicon-based spheres or silicon-based glass balls.
As shown in fig. 7, the refractive indexes of the silicon spheres 1223a include a first refractive index (ne) and a second refractive index (no).
The first refractive index is a refractive index in a major axis 11a direction of the silicon sphere 1223a, and the second refractive index is a refractive index in a minor axis 12a direction of the silicon sphere 1223 a.
Wherein the first refractive index is the same as the refractive index of the liquid crystal 1222a, and the difference between the first refractive index and the second refractive index is 0.1-0.2.
In another embodiment of the present invention, as shown in fig. 8, a dichroic dye 1221a and a silicon ball 1223a are proportionally added to a liquid crystal layer of a second liquid crystal cell 120a, when the second liquid crystal cell 120a is in an energized state, the liquid crystal 1222a rotates, and the dichroic dye 1221a is aligned along the liquid crystal 1222a to present a transparent state; as shown in fig. 9, when the second liquid crystal cell 120a is not powered on, the liquid crystal 1222a is in a dark state when not rotated, the refractive index direction of the silicon spheres 1223a matches the refractive index of the liquid crystal 1222a in the light transmission direction, and the silicon spheres 1223a have no light absorption along the light transmission direction, so that the second liquid crystal cell 120a is in a light transmission state, and thus the transparency can be increased, and the brightness can be improved.
When the second liquid crystal cell 120a is in a dark state, the scattering and absorption states in the direction of absorption of the silicon spheres 1223a are better, and thus the contrast of the second liquid crystal cell 120a is higher.
In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.
The present invention has been described in detail, and the principle and the implementation of the present invention are explained by applying specific examples, and the description of the above examples is only used to help understanding the technical scheme and the core idea of the present invention; those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
