Abstract
The invention relates to a bilaterally displayed OLED (Organic Light-emitting Device) and a preparation method thereof. The bilaterally displayed OLED comprises a first substrate, a second substrate and a packaging piece, wherein a first OLED is arranged on the first substrate; the second substrate is arranged opposite to the first substrate, and a second OLED is arranged on the second substrate; and the packaging piece is positioned between the first OLED and the second OLED and respectively bonded with the first substrate and the second substrate through packaging glue. The bilaterally displayed OLED of the invention has the characteristics that two light-emitting surfaces can carry out completely independent light-emitting display and can not interact.
Description
Technical field
The present invention relates to field of optoelectronic devices, relate in particular to OLED device of a kind of double-sided display and preparation method thereof.
Technical background
Organic electroluminescence device (OLED) has lot of advantages and possesses extremely strong competitiveness as a kind of new display spare and existing main flat-panel monitor liquid crystalline phase ratio.The general structure of organic electroluminescence device comprises successively: matrix, anode, organic layer, negative electrode, organic function layer comprises emission layer (EML) again, can also comprise hole injection layer (HIL) and/or hole transmission layer (HTL) between anode and emission layer, and electron transfer layer between emission layer and negative electrode (ETL) and/or electron injecting layer (EIL), can also comprise hole blocking layer (HBL) between emission layer and electron transfer layer etc.
Present OLED product substantially all is to be used for common light emitting display, realizes that by drive independence is luminous if OLED can satisfy the two sides simultaneously, then can improve the practical value of OLED display products greatly.
In the prior art, be two luminous components of preparation on same device substrate as CN200610004422.1, CN200610036679.5, luminous to different directions respectively; As CN200510022930.8, CN200510052900.1 then is to prepare two OLED devices respectively in the both sides of same device substrate, and the direction outside substrate is luminous separately; All be to adopt the polarized material realization luminous also just like CN1589075, CN1575073.
More than these patents substantially all realized the OLED that preparation has the double-side function to a certain extent, but these products or structure are too thick and heavy, perhaps preparation technology is quite complicated, thereby cost is higher.
Therefore, research and develop and a kind ofly can realize the double-side function, the New O LED device that does not increase preparation cost again has very big meaning.
Technology contents
The objective of the invention is to overcome the defective of above-mentioned prior art, a kind of OLED device that can realize double-sided display is provided, provide simultaneously that a kind of cost is low, the simple preparation method of technology.
For achieving the above object, technical scheme of the present invention is:
A kind of double side display organic electroluminescence light emitting device comprises: one first substrate, and first organic electroluminescence device is arranged on this first substrate; One second substrate is oppositely arranged with first substrate, and second organic electroluminescence device is arranged on this second substrate; A case chip, between above-mentioned two organic electroluminescence devices, and bonding respectively by packaging plastic and above-mentioned two substrates.
Above-mentioned first organic electroluminescence device and second organic electroluminescence device are respectively by two driving device controls.
Above-mentioned case chip can all be provided with groove on relative with two organic electroluminescence devices respectively face, be placed with drier in the groove.
Perhaps above-mentioned case chip also can be provided with at least one groove on the face relative with first organic electroluminescence device, be placed with drier in the groove, and case chip is provided with at least one hole.
Above-mentioned first substrate of the present invention and second substrate are transparent, and case chip is transparent or opaque.
First organic electroluminescence device of the present invention is as the light source display device, and second organic electroluminescence device is as matrix display spare.
Two organic electroluminescence devices perhaps of the present invention are all as the light source display device.Two organic electroluminescence devices perhaps of the present invention are all as matrix display spare.
The present invention also proposes a kind of preparation method of double side display organic electroluminescence light emitting device, comprises that step is as follows:
One first substrate is provided, first organic electroluminescence device is prepared on first substrate; Case chip is prepared on first substrate to encapsulate first organic electroluminescence device by the packaging plastic bonding; One second substrate is provided, second organic electroluminescence device is prepared on second substrate; Assemble this first substrate and second substrate, the another side of case chip is bonding to encapsulate second organic electroluminescence device by the packaging plastic and second substrate.
The beneficial effect of double-side display device of the present invention is:
(1) two light-emitting area can independent fully luminous demonstration, not influence mutually.
The performance index of (2) two light-emitting area devices (brightness, efficient, life-span etc.) are in full accord with the single face individual devices.
