One λ/4 thin film and a polaroid are set on light direction
The process of display device mirror function of the prior art and normal display function is as follows:
(1) mirror function: now OLED is in non-light emitting state, exterior light is similar to nature
Light, for the set of line polarized light in all directions, after the first polaroid, becomes polarization side
To the line polarized light that direction of principal axis is vertical that absorbs with described polaroid, then postpone through λ/4 thin film
After become the circularly polarized light of left-hand/right-hand, become dextrorotation after being reflected by the reflecting layer of OLED
/ left-handed circularly polarized light, becomes polarization direction and described polarisation after postponing again by λ/4 thin film
Sheet absorb the vertical line polarized light of direction of principal axis, it is thus possible to from polaroid outgoing, reach fine
Reflecting effect, thus there is mirror function；
(2) function is normally shown: now OLED is in luminance, the light that OLED sends
Line is similar to nature light, for the set of line polarized light in all directions, is postponed by λ/4 thin film
The most still it is similar to nature light, realizes display by polaroid outgoing the most again.But work as exterior light
In the case of stronger, display device has preferably mirror function equally, and this is with regard to serious shadow
Ring normal display effect.
Aforesaid way can play mirror merit in the case of OLED does not send any light

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is made the most in detail
Describe.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
Fig. 1 is the structural representation of apparatus of the present invention.The invention provides a kind of organic light emission two
Pole tube display device, this display device includes: organic light emitting diodde desplay device 4, successively position
Liquid crystal layer on described organic light emitting diodde desplay device 4 and polaroid 1.The present embodiment
In, liquid crystal layer includes: first substrate 21, second substrate 22 and be filled in liquid crystal between the two and divide
Son 3, described first substrate 21 and second substrate 22 surface the most in opposite directions are sequentially provided with oriented layer.

21 and second substrate 22 surface the most in opposite directions be equipped with one layer of electrode), described electrode structure is used
In forming the electric field making described liquid crystal molecule deflect.Described organic light emitting diodde desplay device 4
Include successively: transparent positive electrode, hole transmission layer, organic luminous layer, electron injecting layer and negative
Electrode.
The absorption direction of principal axis of the slow axis direction of described liquid crystal molecule 3 and described polaroid 1 is in advance
Clamp angle, so that organic light emitting diodde desplay device is when non-display state, enters from polaroid
It is mapped to the exterior light of organic light emitting diodde desplay device through organic light emitting diodde desplay device
Again from described polaroid outgoing after reflection, even if extraneous light reflection, display device is made to have mirror
The effect of son.Liquid crystal initial orientation can be realized by predetermined angle by oriented layer.
Wherein, predetermined angle can be: 30 °～60 °, 15 °～15 ° or 75 °～105 °, excellent
Elect as: 40 °～50 °, 5 °～5 ° or 85 °～95 °.In the face of described liquid crystal layer, length of delay is
100nm～180nm, preferably 130nm～150nm.

:
1) when not applying the slow axis direction of electric field and described liquid crystal layer on described liquid crystal layer with described
When the axial angle of absorption of polaroid 1 is 30 °～60 °, length of delay in the face of described liquid crystal layer
For 100nm～180nm, described liquid crystal layer etc. is considered as λ/4 thin film；Exterior light is nature light, is
The set of line polarized light in all directions, after described polaroid 1, light becomes inclined
That shakes direction and described polaroid 1 absorbs the line polarized light that axle is vertical, prolongs through described liquid crystal layer
Lag and become circularly polarized light or the elliptically polarized light of left-hand/right-hand, this circularly polarized light or elliptical polarization
Light incide the electrode of OLED change into the dextrorotation/left circularly polarized light rotated in mutually opposite directions or
Elliptically polarized light and be again incident on liquid crystal layer (being equivalent to λ/4 thin film) postpone after again become inclined
That shakes direction and described polaroid 1 absorbs the line polarized light that axle is consistent, and light is by described polaroid 1
Absorb, therefore light can not outgoing, thus efficiently perform anti-reflection function, the most do not possess mirror
Subfunction, when display, exterior light does not interferes with the light that OLED sends, and makes display device normal
Display.
Wherein, differing of exterior light of reflection is set to the electrode of OLED, it is also possible at OLED
The vacuum section deposit metal dust such as argentum powder, titanium valve of device, independently forms reflection window or bonding
Reflective film forms mirror, or at the electron injecting layer within OLED or hole transmission layer
Middle mixing can be promoted the reflectance of external light reflection rate and promote material to realize mirror function.?
