Abstract
The invention discloses an electroluminescent device with elastic stretching. The device comprises a transparent conductive composite layer, an elastic stretching electroluminescent layer, and an elastic stretching conductive substrate; wherein the elastic stretching electroluminescent layer is a film prepared by mixing electroluminescent material and resin rubber; the transparent conductive composite layer is formed by compositing a nanometer conductive material and rubber; the elastic stretching conductive substrate is prepared by mixing a conductive material and rubber; the elastic stretching electroluminescent layer is arranged between the transparent conductive composite layer and the elastic stretching conductive substrate; when an electric field is applied between the transparent conductive composite layer and the elastic stretching conductive substrate, the elastic stretching electroluminescent layer generates luminescence; and the electroluminescent device has flexible stretching and springback properties under the effect of an external force.
Description
technical field [0001] The invention belongs to the technical field of electroluminescent devices application. Background technique [0002] Electroluminescent devices have been widely used in the fields of light emission, display and lighting. The existing electroluminescent devices are mainly plastic film devices, glass devices, linear devices, enamel devices, etc., and their substrates are made of plastic, glass, Enamel, metal wire, woven cloth, etc., because the basic matrix materials they rely on are plastic films, glass, metal sheets, metal wires, woven cloth, etc., all of which do not have tensile properties, so they do not have elastic tension when they emit light. Stretching nature. At the same time, they use conductive materials containing lithium ions to form interlayers, which seriously weaken the capacitive properties of electroluminescence and complicate the structure of electroluminescence devices, resulting in low luminous intensity and high driving voltage,...
