Abstract

The invention provides a method for manufacturing a stereo inorganic electroluminescent device. The method comprises steps of pretreating a substrate, configuring slurry of each functional layer and sequentially spraying the functional layers on the substrate by spraying. The method is advantaged in that the process is simple, continuous production can be achieved, a problem that printing methodssuch as screen printing or gravure printing cannot produce continuous light emitting films on surfaces of three-dimensional substrates or irregular substrates in the prior art can be solved, the lightemitting films can be continuously produced directly on a surface of any substrate, the light emitting films are even and uniform, the light emitting effect is not affected by the shape of the substrate, moreover, no template is needed, a spraying path can be directly controlled directly by a spraying program, arbitrary patterning is achieved, and automatic production is made to be easier.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of inorganic electroluminescence, and in particular relates to a method for manufacturing a three-dimensional inorganic electroluminescence device. [0003] 【Background technique】 [0004] EL electroluminescence refers to the self-luminescence phenomenon of the luminescent layer under the action of an external electric field. It is characterized by active luminescent cold light source, surface luminescence and uniform light source without spots, low power, long life (greater than 5000h), and wide operating temperature range (-40 ~70°C). The luminescent film is mainly composed of 4 layers: anode, dielectric layer, luminescent layer and cathode. There are many methods for preparing these 4 layers of film. At present, Meyer rod coating method, screen printing method, transfer printing method, spinner Coating method and drop coating method, the film layer prepared by these methods shows good performance...
