Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.
Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.In the absence of conflict, following embodiment and implementation
Feature in example can be combined with each other.
Fig. 1 is the structural schematic diagram of existing display device, as shown in Figure 1, including at least by polaroid 11, quarter wave plate
12, the display component that oled layer 13 is constituted.Since the electrode layer of oled layer 13 is generally made of metal material, OLED
Layer 13 has higher reflectivity, will form stronger light reflection when environment light reaches oled layer 13.
In order to eliminate influence of the reflection to display effect of environment light, 11 He of polaroid is provided in the top of oled layer 13
Quarter wave plate 12.Its specific action principle is as follows:
The emergent light and environment light that oled layer as where oled layer issues are the rotatory polarization (track of light vector endpoint
For an ellipse, i.e., light vector constantly rotates, the regular variation at any time of size, direction).Therefore, when environment light passes through partially
It can be changed into when mating plate 11 and pass through after quarter wave plate 12, obtain with the consistent line polarisation in the polarization direction of polaroid 11, the line polarisation
To left-handed (or right) circularly polarized light, left-handed (or right) circularly polarized light is reflected after reaching oled layer 13 by oled layer 13, forms reflection
Light.The reflected light formed after being reflected by oled layer 13 is dextrorotation (or left-handed) circularly polarized light, dextrorotation (or left-handed) circularly polarized light
After quarter wave plate 12, the line polarisation vertical with the polarization direction of polaroid 11, therefore meeting when by polaroid 11 are formed
It is all absorbed by polaroid, to eliminate environment light in the reflection effect of oled layer 13, improves display effect.
But using aforesaid way, the emergent light that oled layer 13 issues passes through after quarter wave plate 12, wherein with polaroid
The vertical polarised light in 11 polarization direction is absorbed (theoretically at most only 50 percent light can penetrate polaroid), from
And the brightness of display component is made apparent decaying occur, to influence the display effect of display.
In view of the above-mentioned problems, the present invention is intended to provide a kind of display device and display, are existed with solving external environmental light
The low technical problem of the light transmission rate that reflection problems caused by oled layer and oled layer issue.
Fig. 2 is the structural schematic diagram for the display device that the embodiment of the present invention one provides；As shown in Fig. 2, the dress of the present embodiment
Set includes: the oled layer 21 being stacked, quarter wave plate 22, the first conductive basal layer 23, controllable liquid crystal layer 24, the second conductive base
Bottom 25；It include: liquid crystal molecule 2401 and dichroic dye 2402 in the controllable liquid crystal layer 24.
In the present embodiment, the liquid crystal molecule 2401 in the controllable liquid crystal layer is nematic liquid crystal molecule, the quarter wave plate
Fast axis direction or slow-axis direction, the angle between the first orientation direction of the nematic liquid crystal molecule is 45 degree.This
In embodiment, quarter wave plate can make the polarization state of rotatory polarization rotate 45 degree, when rotatory polarization is after quarter wave plate or circle is inclined
Light.
In the present embodiment, nematic liquid crystal molecule refers to the liquid crystal being under nematic phase, when it is in its natural state
When a field is applied the rotation of certain angle can occur for approximate horizontality, so that liquid crystal molecule presentation is approximately perpendicular
State.Therefore, liquid crystal molecular orientation state can be controlled according to the strong and weak situation of external environmental light, it is stronger in external environmental light
When, so that liquid crystal molecules parallel orientation is played the role of similar linear polarizer, plays and reduce screen reflection and raising Display Contrast
Effect.When external environmental light is weaker, keep liquid crystal molecule vertically oriented, so that the light that oled layer issues almost can whole light transmissions
Controllable liquid crystal layer.
Specifically, when making controllable liquid crystal layer, can by optical cement (Optically Clear Adhesive,
OCA) quarter wave plate is pasted on oled layer, the first conductive basal layer is then made on quarter wave plate, then by roll-to-roll
The mixture that technique or spin coating proceeding are blended with liquid crystal molecule and dichroic dye be made in the first conductive basal layer and

2401 and dichroic dye 2402 be orientated according to second direction so that the light that the oled layer 21 issues all pass through it is described
Controllable liquid crystal layer 24.
Specifically, when dichroic dye 2402 is orientated according to second direction, the environment light for defaulting incidence is weaker, therefore
Its reflection effect on oled layer can almost ignore (at this point, controllable liquid crystal layer disappears to the absorption of environment light).This
When the light that issues of oled layer by after quarter wave plate, polarization angle rotates 45 degree, and the light is by will not be by when controllable liquid crystal layer
Dichroic dye 2402 absorbs, and therefore, the light that theoretically oled layer issues can all pass through controllable liquid crystal layer 24.
