Abstract

The invention discloses a reusable flexible inorganic electroluminescent device, comprising a plastic film layer printed with image-text information, a non-setting adhesive layer, a transparent electrode layer, a luminescent layer, an insulating layer and a back electrode layer in sequence from bottom to top. The non-setting adhesive layer is adhered to the transparent electrode layer in a roll coating mode; the transparent electrode layer, the luminescent layer, the insulating layer and the back electrode layer are tightly attached to one another in a screen printing mode, and the plastic film layer and the non-setting adhesive layer are tightly attached to each other in a manner of being capable of being repeatedly stripped and bonded. The flexible inorganic electroluminescent device prepared by the invention serves as a light source of a thin light box, and can achieve the purpose of reuse through repeated stripping and bonding of the plastic film layer, replacement of image-text content is relatively convenient and easy, resources are saved, and waste is reduced.

Description

technical field [0001] The invention belongs to the technical field of inorganic light emitting diodes, relates to a flexible inorganic electroluminescent device, in particular to a reusable flexible inorganic electroluminescent device. Background technique [0002] Inorganic electroluminescence device (ELD) generates an alternating electric field by applying an alternating voltage on the two poles, and the electrons excited by the electric field hit the fluorescent substance (ZnS), causing jumps, changes, and recombination of electron energy levels to emit high-efficiency luminescence. kind of structure. It features a fully cured structure that generates no heat and contains no UV rays. EL backlight has high luminous efficiency, low power consumption, long service life, anti-vibration, and is surface-emitting, and the color is very uniform. [0003] At present, flexible electroluminescent devices adopt a "sandwich" structure, that is, transparent electrodes, back electr...
