Electroluminescent device

Abstract

The invention relates to an electroluminescent device. The electroluminescent device comprises an electron emission layer, an energy storage reflective layer, an electron excitation layer, an electronrecovery layer, a first electrode and a second electrode, wherein the electron emission layer is made of conductive silver paste, and the conductive silver paste is formed by mixing a mixture of silver nanoparticles and silver nanowires with a high polymer material; the energy storage reflective layer is attached to the electron emission layer; the electron excitation layer is attached to the energy storage reflective layer; the electron recovery layer is attached to the electron excitation layer; the first electrode is attached to the electron emission layer; and the second electrode is attached to the electron recovery layer. The electroluminescent device provided by the invention is a low-voltage electroluminescent device, and the potential safety hazard of the electroluminescent device can be reduced and the application field is broadened within the range of the operating voltage safe to the human body.

Description

technical field [0001] The invention relates to an electroluminescent device, in particular to a low-voltage electroluminescent device. Background technique [0002] Electroluminescent devices have attracted more and more attention due to their advantages of high flexibility, light weight, low energy consumption and fast response. However, the direct driving voltage of the electroluminescent device is relatively high, generally AC 60 volts to 150 volts, which is easy to age the material and form a breakdown point, which greatly affects the product life. Moreover, since the driving voltage is much higher than the safe voltage of the human body, there is a large potential safety hazard of electric shock during application, which seriously limits its application in products that are in close contact with the human body. [0003] For this reason, there is an urgent need in the art for an electroluminescent device that can be driven at a lower voltage. Contents of the inventio...
