Electric refrigerating light assembly and manufacturing method thereof

Abstract

The invention discloses an electric refrigerating light assembly and a manufacturing method thereof, wherein the electric refrigerating light assembly comprises a back electrode conducting layer, a dielectric layer, a refracting layer, an inorganic electroluminescence body layer, a transparent insulating layer, an ITO (indium tin oxide) film and a transparent insulator, wherein the ITO film is provided with a net-shaped busbar wire used for a public electrode. The electric refrigerating light assembly and the manufacturing method thereof provided by the invention can be used for overcoming the defects that a dark spot and a breakdown point are easy to appear, the glowing brightness is poor, the photoelectric property is bad and the like in the prior art, and achieving the advantages that the dark spot and the breakdown point are not easy to appear, the glowing brightness is good, and the photoelectric property is good.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an electroluminescence component and a production method thereof. Background technique [0002] In recent years, with the development of high performance and diversification of various electronic devices, flat-plate electroluminescent elements are often used for lighting in many occasions. With the addition of silk screen printing technology, the threshold of production equipment and technology has been lowered. At present, there are many manufacturers engaged in the production of this product in the market, and the product forms are becoming more and more colorful. [0003] For example, in figure 1 and figure 2 Among them, the electroluminescent sheet includes a back electrode conductive layer 5, a dielectric layer 4, an inorganic electroluminescent layer 3, an ITO film 2 and a transparent insulator 1 that are stacked in sequence, and a strip-shaped common electr...

AI Technical Summary

Problems solved by technology

[0005] ⑴The quality of the product cannot be maintained for a long time. During the half-life period (some even within a short period of time), there will be partial breakdown, black spots, dark spots and other defects, and the luminous quality will decline seriously;

[0006] (2) Most of the dielectric layer uses barium titanate as the base material to increase the dielectric constant, but the reflective ability is insufficient, and there is even light leakage on the back, and the conversion of photoelectric efficiency is not high, which affects the luminous brightness of the front;

[0008] In the process of realizing the present invention, the inventors found that there are at least defects in the prior art that are prone to dark spots and breakdown spots, poor luminous brightness, and poor photoelectric performance.
