MANUFACTURING METHOD OF EL SHEET USING DOUBLE LAYER FILM FOR BACKLIGHT OF KEYPAD AND MANUFACTURING METHOD OF EL METAL DOME SHEET AND EL METAL DOME SHEET THEREOF

摘要

An EL(ElectroLuminescent) sheet for a keypad using a flexible double layer film, a method for manufacturing an EL metal dome sheet, and the EL metal dome sheet using the same are provided to reduce the whole thickness by forming transparent conductive films with the thin films of a double structure. A method for manufacturing an EL metal dome sheet includes the steps of: manufacturing an EL sheet(S51); forming an adhesive layer on the back of the EL sheet to improve click feeling for forming places of various shapes(S52); manufacturing a metal dome sheet with a space to insert a metal dome(S61); inserting the metal dome into the space(S62); completing the EL metal dome sheet by laminating the manufactured EL sheet and the metal dome sheet with a top tape(S70); and using the EL metal dome sheet for a keypad by laminating a key panel onto a top portion of the EL metal dome sheet(S80).
