Abstract
The utility model discloses electroluminescent screen and sheet which comprise a lower moisture-proof insulation layer and an upper moisture-proof insulation layer. A back electrode, an insulation medium layer, an electroluminescent layer and an ITO transparency conductive film are respectively arranged between the lower moisture-proof insulation layer and the upper moisture-proof insulation layer; an electrode lead made of a flexible circuit board FPC is connected with the back electrode; the other electrode lead made of a flexible circuit board FPC is connected with the ITO transparency conductive film. Due to the fact that the electroluminescent screen and sheet tanks the flexible circuit board FPC as the electrode lead, the thicknesses of the electroluminescent screen and sheet can be reduced; moreover, the electrode lead can be bended and coiled, and the reliability is high, thereby, the quality of the electroluminescent screen and sheet is ensured; in addition, an insulating film is coated on the electrode lead, which makes the electroluminescent screen or the electroluminescent sheet can not be short-circuited when arranged in a metal frame, and the use is safe. The utility model can be widely applied to indicator lamps for fire fighting emergency evacuation, art wares and the advertisement decoration.
Description
Technical field
The utility model relates to electroluminescence screen and light tiles, particularly a kind of electroluminescence screen and light tiles that is used for fire-fighting emergent evacuation direction identification light, handicraft and ad decoration.
Background technology
Being used for the electroluminescence screen of fire-fighting emergent evacuation direction identification light, handicraft and ad decoration and the contact conductor of light tiles at present is to adopt stainless steel electrode, be characterized in certain thickness, hardness is stronger, bendability is relatively poor, fracture easily, cause electroluminescence screen or light tiles in the process of producing, transport, assembling and using, to be damaged, make that rate of finished products is low, useful life short, as long as contact conductor fractures, whole electroluminescence screen or light tiles promptly may can not be repaired.In addition, when existing electroluminescence screen or light tiles were installed in metal framework, because contact conductor is a metal material, and does not have insulating barrier, thereby contacting metal framework short circuit was easily used dangerous.
Summary of the invention
In order to solve the above problems, the purpose of this utility model is to provide a kind of good reliability, ultra-thin, a kind of electroluminescence screen and the light tiles that are easy to assemble.
The technical scheme in the invention for solving the above technical problem is:
A kind of electroluminescence screen and light tiles, comprise damp proof insulation layer and last damp proof insulation layer down, back electrode, insulation interlayer, electroluminescence layer and ITO nesa coating are arranged between following damp proof insulation layer and the last damp proof insulation layer successively, it is characterized in that: the contact conductor of being made by flexible circuit board FPC is connected stickup with back electrode, and another is connected stickup by the contact conductor that flexible circuit board FPC makes with the ITO nesa coating.
In addition, the outer surface of the described contact conductor of being made by flexible circuit board FPC has insulation film respectively.
The beneficial effects of the utility model are: adopted flexible circuit board FPC as contact conductor, because the thin thickness of flexible circuit board FPC, can reduce the thickness of electroluminescence screen and light tiles, and this contact conductor is flexible, coiling, good reliability, thus make the rate that manufactures a finished product of electroluminescence screen and light tiles higher, product quality is more guaranteed.In addition, on this contact conductor, be coated with insulation film, make electroluminescence screen or light tiles be easy to be installed in the metal framework, can short circuit, safe in utilization, good reliability.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is that the B-B of Fig. 1 is to cutaway view.
Embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of electroluminescence screen and light tiles comprise following damp proof insulation layer 1 and the last damp proof insulation layer 2 made by clear glass or other transparent material.Back electrode 3, insulation interlayer 4, electroluminescence layer 5 and ITO nesa coating 6 are arranged between following damp proof insulation layer 1 and the last damp proof insulation layer 2 successively, back electrode 3 is silver slurry layers, ITO nesa coating 6 forms an electric loop with back electrode 3, constitutes literal or pattern by electroluminescence layer 5.
The contact conductor of being made by flexible circuit board FPC 7 is connected stickup with back electrode 3, and another is connected stickup by the contact conductor 8 that flexible circuit board FPC makes with ITO nesa coating 6, forms public electrode.Because flexible circuit board FPC is to be base material with mylar or polyimides, have the reliability of height, excellent flexibility, can bend, thus very convenient when installing and using.
The outer surface of the described contact conductor of being made by flexible circuit board FPC 7,8 can have additional insulation film 9 respectively, this insulation film 9 was to mould to be fixed on the contact conductor, can prevent the appearance of short-circuit conditions after its contact conductor and the extraneous Metal Contact, make this electroluminescence screen or light tiles can be installed in easily on each class framework that comprises metal framework.
Described insulation film 9 is coated on a side or the both sides of the outer surface of the contact conductor of being made by flexible circuit board FPC 7,8, and it is decided according to the actual requirements.
In addition, in order to strengthen the performance that conducts of public electrode, the described contact conductor of being made by flexible circuit board FPC 8 is connected with ITO nesa coating 6 by silver slurry layer 10.
In the utility model,, then be electroluminescence screen as adopting clear glass or the big transparent film of hardness; As adopt the soft transparent film, then be EL sheet.
