Problems solved by technology

[0004] There are several problems in such a technology of doing EL light emission on the reverse side of the ITO film substrate: it is difficult to separate and recycle materials such as printing luminescent materials and conductive silver paste on plastic materials such as PET; The upper layer of printing is a conductive layer, and there is a possibility of electric shock. It is necessary to add a layer of insulating film or other protective measures on the top layer. There is an extra layer of structure in the processing technology.

Description

technical field [0001] The invention relates to the technical field of electroluminescence, in particular to an electroluminescence sheet and a manufacturing method of the electroluminescence sheet. Background technique [0002] Currently, the mainstream light-emitting display technology researched on the market is Organic Light-Emitting Diode (OLED) for short. The process of OLED light-emitting display technology has very high requirements on the environment and must be carried out in an oxygen- and water-free environment. Impurities in the air will cause breakdown and affect the lifetime of light emission. OLED has relatively high requirements on materials. At present, the mature OLED technology is made of plastic film such as PET or glass with evaporation process. [0003] In addition to OLED light-emitting display, electroluminescent (Electro Luminescent) is also one of the mainstream. The substrate of electroluminescent sheet is mainly plastic substrate such as PET. El...
