Problems solved by technology

U.S. patents US4585673, US5156885 and Chinese patent ZL01138921.4 disclose complex coating preparation technology. The price of coated moisture-proof luminescent powder is 5-8 times that of non-coated moisture-proof materials, and its cost is high. If non-coated luminescent materials are used, Lifespan is usually only 500-1000 hours
In the prior art, pink or red organic dyes are used for white luminescence. If they work continuously under an electric field for 100 hours or leave them outdoors for 10 days, the organic dyes will decompose and fade, causing the white luminescence to turn into light blue.

Abstract

The invention consists of a baseline body, a metal decorating layer covering on outside of the baseline body, a dielectric layer covering on the metal decorating layer, a light emitting layer covering on the dielectric layer, a transparent conducting layer covering on the light emitting layer and connected to an out-guard wire. All layers are sealed by fluoroplast.

Description

technical field [0001] The present invention relates to a light-emitting display device in light-emitting physics, in particular to an electroluminescent line that uses an electric field to emit light. Background technique [0002] Linear light-emitting display devices driven by electric energy have been widely used in our life and production. At present, linear light-emitting display devices are mainly realized in two ways: continuous linear light-emitting and dot-matrix combined linear light-emitting. Neon lamps, cold cathode lamps and plastic light made of glass tubes are typical representatives of continuous light-emitting devices, which are characterized by high brightness, rich colors, high power consumption, and one-time molding; dot-matrix combined linear light-emitting devices are mainly neon bulbs Combined with semiconductor light-emitting diodes (LEDs), which are arranged at intervals in a certain direction, they are combined into a linear light-emitting device. ...
