Abstract
The invention relates to a method for using epoxy resin, ethyl carbamate, and acrylate and nitride organic silicon polymer at vacuum condition to coat and strengthen chemical gas deposit to pack the film element, to form one organic electroluminescent element with flexible structure and lighting top. The invention has simple process, lower cost and dual-surface large display.
Description
The present invention relates to some common resin materials, handle encapsulation technology, realize the preparation and the application thereof of the organic electroluminescent of full flexible top luminescent by film.
The organic electroluminescent device is a kind of novel planar display device, has ultralight, ultra-thin, low-power consumption, full visual angle, can be complementary with the low temperature polycrystalline silicon integrated circuit technique, easily realizes full-colorization, and its luminosity height, response speed are fast.Present undersized organic electroluminescent device, can satisfy application requirements useful life, but large-sized life-span is also very short, but also fail really to accomplish flexible the demonstration and top light emitting.At present, abroad all attempt in this respect in (Japan and the United States, Europe etc.), but fall far short from practicality, new structure, material and the processing technology of seeking to satisfy the full flexible top luminescent of organic electroluminescent device become hot of research and development and keys such as current organic electroluminescent device.
Flexible top luminescent promptly allows light directly emit from substrate.Thereby require the substrate tool transparency, flexibility.Flexible substrate can be with allowing the display as picture that organic electroluminescence device is used becomes deflection.Nitrogenize organosilicon polymer and various resin all are the electric devices that satisfies above-mentioned requirements.Wherein, the nitrogenize organosilicon polymer have low temperature flexibility, low-surface-energy, high temperature resistant, weather, corrosion-resistant, hydrophobicity good, the dielectric strength advantages of higher; And be that the various lipoid substances of representative have good mechanical performance, resistance to wear, anti-solvent, antioxygen gas permeability, water proofing property, easily machine-shaping, advantage such as with low cost with epoxy resin.The present invention will adopt above-mentioned material to finish the encapsulation and the preparation of the organic electroluminescent device of flexible top luminescent.
Purpose of the present invention is exactly that flexibility, transparent material substitute glass substrate and other encapsulating materials in the existing organic electroluminescent device, makes device realize complete flexible, top light emitting demonstration.
Order of the present invention is achieved in that at first and replaces glass substrate with flexible plastic substrate, is coated with inorganic layer materials, organic layer material respectively in the top of plastic then.Be coated with anode material, luminescent layer material, cathode material, organic layer material, inorganic layer materials respectively on inorganic layer materials, organic layer material base, thereby finish the preparation and the encapsulation of entire device.
Main raw material(s) that the present invention relates to and equipment
Nitrogenize organosilicon polymer (SINX), urethanes (URETHANE), propionic ester (QCRYLATE), epoxy resin (EPOXY), flexible transparent plastic, aluminium, magnesium, the F series organic electroluminescent device equipment of Chengdu organosilicon research institute of the Chinese Academy of Sciences, Korea S SANIC company 200 * 200.The wherein raw-material producer that provides only is to illustrate channel, and not in restriction the present invention.
One, the structure of flexible organic electro-luminescence device, technology path and characteristics
(1) structure chart (seeing figure one)
(2) technology path
At first anode (lead), cavitation layer material (HTL), luminescent layer material (EML), electronic shell material (ETL), negative electrode (magnadure) are printed organic layer (epoxy resin) then, are smeared inorganic layer (SiNx) on evaporation on the flexible transparent plastic substrate, print organic layer again, epoxy resin or acrylate are finished top encapsulation.At the flexible transparent plastic another side, smear inorganic layer (SiNx) accordingly, print organic layer (epoxy resin, acrylate, urethanes), smear inorganic layer, print organic layer and finish bottom package.
(3) organic polymer thin-film material flat surface reduces body effect; The macromolecule resin film can effectively stop extraneous mechanical damage, and plural layers can effectively stop moisture and oxygen, prolongs device lifetime.
Two, the structure of top organic electroluminescent device, technology path and characteristics:
(1) structure chart (seeing figure two)
(2) technology path
At first in glass substrate, anode ITO goes up Mo and is coated with machine luminescent material (HTL, EML, ETL), add negative electrode ITO Mo, smear levelling blanket (epoxy resin) again, print organic layer (the vinegar-pepper ester of propylene), smear inorganic layer (SiNx), print organic layer (acrylate), finish element manufacturing and encapsulation.
(3) characteristics
As can be seen, the various parameters (hole rate, power consumption, thin-film package) of the organic electroluminescence device of employing top light emitting all are better than the device of bottom-emission from figure three.
Adopt the top light emitting technology will make the color of organic electroluminescent device more bright-coloured from figure four as can be seen, luminous efficiency is higher.
Example 1:
Finish flexible device according to above-mentioned flexible organic electro-luminescence device structure and technology preparation.After its encapsulation is finished 24 hours, cut-in voltage V
o=10.5, I

1=10.02 V
1I
1=2.0MA surveys 2800CD/ square metre of its high-high brightness down, illustrates that its flexible device preparation is successful, and device performance is good.
Example 2:
Structure and technology according to above-mentioned top organic electroluminescent device prepare the top light emitting device of finishing.After its encapsulation is finished 24 hours.At V
1=10.01 V
1I
1It is 3100CD/ square metre that=2.08MA surveys its high-high brightness down, and January after the encapsulation is at V
1=10.08V
1I
1It is the 2980CD/ cubic meter that=2.58MA surveys its high-high brightness down, illustrates that this top light emitting device preparation is successful.Device performance is good.
