Background technology
Inorganic electroluminescence device（ELD）It is to produce AC field by being added in the alternating voltage at the two poles of the earth, is excited by electric field
Electronic impact fluorescent material（ZnS）, cause the jump, change, one kind that is compound and launching high efficiency cold light of electron energy level
Structure.All solidstate structure is characterized in, heat is not produced, without ultraviolet.The luminous efficiency of EL backlights is high, low in energy consumption, uses
Long lifespan, against shock, and be that face lights, color seems very uniform.
Current flexible el device is all using " sandwich " structure, i.e. transparency electrode, back electrode and is clipped in them
Between inorganic functional layer, by making lamp box advertisement etc. in device surface printing figure message information.The deficiency of this structure
It is in higher in luminescent device complex manufacturing technology, cost, and graph text information only has shorter validity period.Once graph text information mistake
Phase, it is necessary to all change luminescent device and graph text information, cause greatly waste.
The content of the invention
The invention aims to overcome the shortcomings of existing light structures, there is provided a kind of flexible nothing that may be reused
Machine emitting, electroluminescent device as lamp box structure light source.
The technical solution adopted in the present invention is：One kind is repeatable to utilize flexible inorganic electroluminescent device, and its feature exists
In：Include being printed on the plastic film layers of graph text information, non-drying glue layer, transparent electrode layer, luminescent layer, insulation successively from bottom to up
Layer, dorsum electrode layer；Described non-drying glue layer is sticked on transparent electrode layer by roller applications；Described transparent electrode layer, hair
Photosphere, insulating barrier, dorsum electrode layer are brought into close contact together by screen printing mode, described plastic film layers and non-drying glue layer
It can peel off repeatedly with adhesively fitting together.
Preferably, described dorsum electrode layer is made using the metal of the low work functions such as Al or Ag.
Preferably, the insulating barrier is using the high material making of the dielectric constants such as silica, aluminum oxide, barium titanate
Into.
Preferably, described luminescent layer is dispersed in organic binder bond by fluorophor powders such as the zinc sulphide that adulterates, lead to
Screen printing mode is crossed to be made.
Preferably, described transparent electrode layer uses ITO（Tin indium oxide）Etc. transparent or semitransparent conductive material system
Form.
Preferably, the adhesive sticker in described non-drying glue layer is to be based on No. 60 solvents, toluene and hexamethylene etc.
Auxiliary material is made.
Preferably, described non-drying glue layer manufacturing process is, adhesive sticker is coated with using roller applications, and ensures that glue-line is equal
It is even, it is ensured that bubble-free is produced.
Preferably, described plastic film layers use PET（Polyethylene terephthalate）Be made, inner side with
Described non-drying glue layer bonding, outside is printed on graph text information.
The non-drying glue layer and plastic film layers that the present invention is newly increased will not be to the property of transparent electrode layer and whole luminescent device
Influence can be produced.
Plastic film layers in the present invention are easily peeled off, and then the plastic film layers for being printed on new graph text information are passed through
Non-drying glue layer is bonded with the transparent electrode layer of luminescent device again, reaches the purpose of reuse.
Flexible inorganic electroluminescent device obtained by the present invention can pass through plastic sheeting as the light source of thin-type lamp box
The stripping repeatedly of layer reaches the purpose of reuse with bonding, and the replacing of graph-text content is more facilitated easy, while saving money
Source, reduces and wastes.
Brief description of the drawings
Fig. 1：The structure chart of the embodiment of the present invention.
Embodiment
Understand for the ease of those of ordinary skill in the art and implement the present invention, below in conjunction with the accompanying drawings and embodiment is to this hair
It is bright to be described in further detail, it will be appreciated that implementation example described herein is merely to illustrate and explain the present invention, not
For limiting the present invention.
See Fig. 1, one kind that the present invention is provided is repeatable using flexible inorganic electroluminescent device, wraps successively from bottom to up
Include the plastic film layers for being printed on graph text information, non-drying glue layer, transparent electrode layer, luminescent layer, insulating barrier, dorsum electrode layer；Adhesive sticker
Layer is sticked on transparent electrode layer by roller applications；Transparent electrode layer, luminescent layer, insulating barrier, dorsum electrode layer pass through screen printing
Brush mode is brought into close contact together, and plastic film layers with non-drying glue layer can be peeled off repeatedly with adhesively fitting together.
The described dorsum electrode layer of the present embodiment is made using metal Al, and insulating barrier uses SiO2（Silica）System
Form, luminescent layer is made using the zinc sulphide of doping, and transparent electrode layer uses ITO（Tin indium oxide）It is made, no
Adhesive sticker in drying adhesive layer is formed from No. 60 solvents, toluene, hexamethylene, antioxidants with, and adhesive sticker uses roller applications
Coating, while ensureing that glue-line is continuous, it is ensured that adhesion strength and peel strength reach an equalization point.Glue is should be noted that during gluing
Layer is uniform, prevents the generation of bubble.A period of time is hung after gluing, with plastic film.
