Abstract
The utility model relates to a novel electroluminescent body which is a powder electroluminescence screen which is provided with a special transparent electrode. The transparent electrode is a transparent conductive particle which is coated by transparent conductive paints made from conductive materials. The transparent conductive particles are made by means of spraying galvanization, steam galvanization, etc. The utility model has the advantages of brief and flexible technology, low cost, high reliability and wide application scope.
Description
The utility model belongs to powder electroluminescence device.
In prior art, powder electroluminescence device has three kinds of screens structure, i.e. polymethyl methacrylate screen, enamel screen and organic flexible soft screens.Wherein enamel screen needs high-purity material to make under high temperature, and the cost height, operation is many, need equipment is also many; Electro-conductive glass is easily broken in processing of polymethyl methacrylate screen and the use, thereby needs strict sealed damp-proof to make course of processing complexity, cost increase, be difficult for making the large tracts of land screen; Organic flexible soft screen mainly is that technology is loaded down with trivial details on the sealed damp-proof, the technological requirement height, and talent-selecting field is narrow, damages easily, needs shortcomings such as large-scale production and corollary equipment.
The purpose of this utility model is the electroluminescence screen that proposes a kind of new construction, make the electroluminescence screen can be in all case, even do not need machinery equipment to make at normal temperatures, one jumps and becomes is easy to implement, weak light source with low cost and decoration, indication, show and colour, thus effective means provided for the competition of electroluminescence and other light sources.
Shown in accompanying drawing (positive view), the utility model is made of protective layer [1], transparent conductive coating layer [2], luminescent layer [3], Withstand voltage layer [4] and second electrode [5].
Second electrode [5] can be metallic plate, the coat of metal, metal film, semiconductor film or adopt any of electrically-conducting paint that conductive powder (as graphite, metal powder) and resin make.Withstand voltage layer [4] and luminescent layer [3] can adopt conventional polymethyl methacrylate to shield withstand voltage reflector layer and the luminescent layer method for making makes.The coating that transparent conductive coating layer [2] is made by electrically conducting transparent particle and mixed with resin makes.Protective layer [1] mainly is to play protection against the tide, protection electrically-conducting paint and protection against electric shock effect, plays the transparent organic materials such as varnish of this effect and all can use.
The utility model its principal character is to have used the transparent conductive coating layer that the electrically conducting transparent particle is made, and this is that the designer consults data at home and abroad and do not have, thereby creates.This electrically conducting transparent particle can adopt some specified particle size thermostable transparent material such as cullet, rubble English, broken glaze, glass microballoon etc. to utilize methods such as spraying plating, evaporation, dip-coating to form conducting film thereon and make.This electrically conducting transparent particle and transparent resin are mixed and made into coating, and filming after it solidifies has lower resistivity and higher light transmittance, and this coating itself promptly has the protective effect that guarantees the luminescent powder protection against the tide.And make structure more compact, can under baking, ultraviolet light or normal temperature, solidify, make the manufacturing environment of this transparency conducting layer become very flexible.
The utility model is compared with enamel screen, and its luminous bisque is because of through 400 degree hot settings with steam conducting film, and influence luminous efficiency and shortening in useful life; Than polymethyl methacrylate screen and organic flexible screen, this coating itself has moistureproof and protection luminescent powder function, and operation has been lacked many, and cost reduces.And because of need not to use large-scale machinery equipment, make the manufacturing of this screen simple, be easy to be extended and applied every field, and can make large-area advertisement, can cause a revolution of electric light source as mopping.
For example, second electrode adopts steel plate, spray Withstand voltage layer and luminescent layer successively thereon, and make the electro-conductive glass microballon through high temperature spraying plating one deck conducting film with 100 purpose glass microballoons, electro-conductive glass microballon and epoxy resin varnish are made electrically-conducting paint with 1: 1 ratio, solidify to form the transparent conductive coating layer through normal temperature, extraction electrode on this electrically-conducting paint layer afterwards, at last, cover the polyurethane lacquer of layer of transparent again, promptly make this kind novel electroluminescent body after the curing.
