Problems solved by technology
The existing electroluminescent sheet is used as a decoration, but it is only pasted on the outer surface of the product. The electroluminescent sheet is attached to the outside of the product, which lacks a sense of integrity and is relatively low-end. The electroluminescent sheet is exposed in the air and is easily affected by the air. The influence of oxygen and water in the medium reduces its stability and life

Abstract
The invention provides an electroluminescence piece, which comprises a substrate film, and a transparent electrode layer, a luminous layer, an insulating layer and a backside electrode layer which are arranged on the substrate film, wherein the transparent electrode layer is an indium tin oxide deposited on the substrate film; the luminous layer is arranged on the transparent electrode layer; the insulating layer is arranged on the luminous layer; and the backside electrode layer is arranged on the insulating layer. The electroluminescence piece comprises an adhesive layer which is arranged on the backside electrode layer. The manufacturing method for the electroluminescence piece comprises the following steps: a, manufacturing the substrate film; b, molding the substrate film through a high pressure molding mold; c, punching the redundant part of the substrate film to form the electroluminescence piece; and d, performing injection molding, wherein the adhesive layer of the electroluminescence piece and plastics in an injection mold are opposite to form a whole through the injection molding. The invention also provides a shell with the electroluminescence piece and a manufacturing method for the shell; and the shell is integrated into a whole with the electroluminescence piece, so the integrity is high.
Description
【Technical Field】 [0001] The invention relates to a light-emitting sheet, in particular to an electroluminescent sheet and a manufacturing method thereof. 【Background technique】 [0002] With the popularization of high-tech products for civilian use, EL (Electrol Liminescent) technology, which was previously only used in the cockpit of aircraft, is now widely used in the field of civilian consumption, in mobile phones, pagers, cordless phones, and personal Digital assistants, remote controls and other products are used as backlight sources. Because the electroluminescent sheet has the characteristics of small size, light weight, basically no heat, low power consumption, no flicker, uniform light emission, and large light-emitting area, it has a very broad market application prospect. [0003] The electroluminescent sheet is printed with electroluminescent material on the insulating substrate, and the electroluminescent sheet is sandwiched between two layers of electrodes, and the ...
