Embodiment of the present utility model provides a kind of reflected displaying device, is carried for example, Fig. 2 is the embodiment of the utility model one
A kind of structural representation of the reflected displaying device supplied.
As shown in Fig. 2 the reflected displaying device 200 includes：The first substrate 201 and second substrate 202 being oppositely arranged, if
Put the first electrode 203 on first substrate 201, be arranged on first substrate 201 the side towards second substrate 202 it is transparent
Dielectric layer 204, is arranged on the second electrode 205 on second substrate 202, is filled between first substrate 201 and second substrate 102
Liquid crystal 206, the refractive index of the liquid crystal 206 becomes in the presence of first electrode 203 and the electric field of the formation of second electrode 205
Change, so that the refractive index of liquid crystal 206 is identical or essentially identical with the refractive index of transparent dielectric layer 204, or less than transparent medium
The refractive index of layer 204.
It should be noted that when the refractive index of liquid crystal 206 is identical or essentially identical with the refractive index of transparent dielectric layer 204
When, light can directly or essentially directly pass through transparent dielectric layer 204 and liquid crystal 206, in the process, and light is situated between from transparent
When matter layer 204 is incident to the interface of liquid crystal 206 and transparent dielectric layer 204, the incident angle of light will not change substantially.
For example, when the brightness of ambient light is larger, from the front of reflected displaying device 200, incident light can be ambient light,
Now ambient light plays a part of display light source；When the brightness of ambient light is relatively low, can additionally it be set on first substrate 201
Light-emitting component is put, incident light can be the light of light-emitting component transmitting from the front of reflected displaying device 200.
For example, first substrate 201 and second substrate 202 can be respectively counter substrate and array base palte, for example, opposed base
Plate can be color membrane substrates.Array base palte includes the drive circuit by array arrangement, and each drive circuit is for example for driving one
Individual pixel, to control the voltage difference in respective pixel between first electrode 203 and second electrode 205, so as to realize display.Light from
The front of reflected displaying device is incident, then first substrate 201 is transparency carrier, for example, glass substrate.
For example, first electrode 203 can be arranged on the side of the close second substrate 202 of first substrate 201, it can also set
Put in the side of the remote second substrate 202 of first substrate 201.In the following description, it is arranged on first electrode 203
It is illustrated exemplified by the side of the close second substrate 202 of one substrate 201.
For example, there are a large amount of anisotropic molecules in liquid crystal 206, the arrangement of a large amount of anisotropic molecules has liquid crystal
Birefringence, and the refractive index of liquid crystal can change with the change of the voltage put on liquid crystal.Adjustment can so be passed through
The size for the voltage being applied on liquid crystal controls the refractive index of liquid crystal.
For example, when the refractive index of liquid crystal 206 is less than the refractive index of transparent dielectric layer 204, light is (i.e. transparent by optically denser medium
Dielectric layer) when being mapped to the interface of optically thinner medium (i.e. liquid crystal), if incident angle is more than critical angle, (i.e. light is by optically denser medium incident light
Dredge the minimum angles being totally reflected during medium) when, just it can be totally reflected.When i.e. incident angle is more than critical angle, light exists
The interface of transparent dielectric layer 204 and liquid crystal 206 is totally reflected, to realize that on state of is shown；When liquid crystal 206 refractive index with it is transparent
When the refractive index of dielectric layer 204 is identical or essentially identical, light passes through transparent dielectric layer 204 and liquid crystal 206, to realize dark-state
(or colored display).
For example, the liquid crystal 206 includes but is not limited to cholesteric liquid crystal, nematic liquid crystal or smectic liquid crystal.For example, working as liquid
When crystalline substance is cholesteric liquid crystal, because cholesteric liquid crystal has bistable state, energy consumption can be further reduced.For example, liquid crystal mean refraction
Rate calculation formula is as follows：Liquid crystal can deflect in the electric field, and refractive index is controllable.
In above formula (1), neFor the refractive index of extraordinary ray, noFor the refractive index of ordinary light, θ is the deflection angle of liquid crystal,
When applying different electric-field intensity to liquid crystal, the deflection angle of liquid crystal can change.So as to cause the refractive index of liquid crystal to occur
Change.
For example, when pixel needs to light (white state), now under electric field controls, liquid crystal is in low-refraction, when liquid crystal
When refractive index is less than the refractive index of transparent dielectric layer, and when the incidence angle of light is more than or equal to light in liquid crystal 206 and transparent
During the minimum angles being totally reflected between dielectric layer 204, the light is totally reflected at the interface of transparent dielectric layer and liquid crystal,
To realize that on state of is shown, when the incidence angle of light is less than the minimum angle that light is totally reflected between liquid crystal and transparent dielectric layer
When spending, the light is injected in liquid crystal.
For example, when pixel needs to realize black state (or colored), high index of refraction is presented in liquid crystal, now liquid crystal 206 with it is transparent
The refractive index of dielectric layer 204 is suitable, i.e., when the refractive index of liquid crystal 206 is identical with the refractive index of transparent dielectric layer 204 or basic phase
Meanwhile, light passes through transparent dielectric layer 204 and liquid crystal 206, and to realize dark-state, black or colour is presented.
When light enters low-index material from high-index material, (light is close from light for the critical angle being totally reflected
During medium incident to optically thinner medium, the incidence angle of light when refraction angle is equal to 90 °) linear with the ratio of refractive index be：
Sin θ=nDredge/nIt is close, when the variations in refractive index of liquid crystal, because the critical angle being totally reflected also changes, the reflectivity meeting of light
Change.So, by controlling the change of the refractive index of liquid crystal 206, cause critical angle to change, so that according to each angle of incidence of light
The difference of degree, realizes that the amount of the light of total reflection is also different, and then can realize the GTG of reflective display.It should be noted that
Incidence angle, angle of reflection and refraction angle each mean the angle of the normal formation at light and interface.
For example, transparent dielectric layer 204 is arranged on the side of the remote first substrate 201 of first electrode 203, and transparent Jie
Matter layer 204 has curved-surface structure, has ups and downs surface in the side towards liquid crystal 206.

Structure, can also be other irregular surfaces, as long as can realize at least from the incident light in reflected displaying device front transparent
It is totally reflected on interface between dielectric layer 204 and liquid crystal 206.These half micro-sphere structures are, for example, the spherical crown or ellipse of ball
The spherical crown of ball.For example, the curved-surface structure is prepared from using nano-imprint process, photoetching process etc..

Rate can be more than liquid crystal refractive index or identical or essentially identical with the refractive index of liquid crystal, with it is transparent the characteristics of, have
Certain hardness.

, the thickness of transparent dielectric layer 204 is along the maximum gauge on the direction of first substrate.
For example, first electrode 203 is formed by transparent conductive material, for example, transparent conductive material can be tin indium oxide
(ITO), indium zinc oxide (IZO) etc..
For example, the thickness of first electrode 203 is 100nm-300nm, for example, 100nm, 200nm, 250nm or 300nm.
For example, second electrode 205 can be formed by metal material, it can also be formed by transparent conductive material.When the second electricity
When pole 205 is formed by metal material, if necessary to realize during colored display, without extra reflecting layer can be set to carry out light
Reflection；When second electrode 205 is formed by transparent conductive material, by setting one layer of reflecting layer again, colour can be equally realized
