Abstract

The invention provides a method for manufacturing a three-dimensional inorganic electroluminescent device, which includes substrate pretreatment, configuration of slurry for each functional layer, and steps of sequentially overlapping and spraying each functional layer on the substrate by a spraying process. The process of the invention is simple and It can be produced continuously, which solves the problem that the printing methods such as screen printing and gravure printing in the prior art cannot produce continuous luminescent films on the surface of three-dimensional substrates or irregular substrates, and can directly continuously produce luminescent films on the surface of any substrate And the luminous film is flat and uniform, and the luminous effect is not affected by the shape of the substrate; in addition, the present invention does not require a template, and the spraying path can be directly controlled through the spraying program, so that arbitrary patterning can be realized and automatic production can be more easily realized.

Description

【Technical field】

[0001] 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. 【Background technique】

[0002] 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 on the flat su...
