Electroluminating lamp and combination of said lamp and metal button board, and mfg. method therefor

Abstract

This lamp consists of a base board (BB), an electric light-emitting system (ELES) printed on the surface of BB, and a protection layer (PL) covering the ELES. ELES consists of two electrode layers (EL) and a medium layer / light emitting layer between two ELs. Covering BB, PL acts as the shell of ELES. There is a glue layer (GL) under the down surface of BB. This invention also offers a combination of an electric light-emitting lamp and metal keyboard (MK). Under GL, MK consists of several metal keys and a pad. There are grooves on the pad to fix the keys. The 2nd glue layer is under the pad. This invention has advantages of simple structure and easy to install.

Description

technical field [0001] The present invention relates to an electroluminescent lamp (EL, Electroluminescent Lamp), a combination of the electroluminescent lamp and a metal dome sheet (Metal dome sheet) and a manufacturing method of the above two products, in particular to a An electroluminescence lamp on an electronic component and a manufacturing method thereof, and a combination of an electroluminescence lamp and a metal key board conveniently pasted on a circuit board and a manufacturing method thereof. Background technique [0002] With the popularization of high-tech products for civilian use, electroluminescence technology, which was only used in the cockpit of aircraft, is now widely used in consumer electronics products, such as mobile phones, pagers, wireless phones, personal digital assistants, remote controls, etc. Products, due to the characteristics of small size, light weight, low temperature, low power consumption, no flicker, and uniform light emission, electr...

AI Technical Summary

Problems solved by technology

The electroluminescent lamp with this structure needs to print two shell layers, and needs to apply an adhesive layer 116 again when using, and it is relatively inconvenient to use.

[0005] And when mobile phone manufacturers use the above-mentioned electroluminescent lamp, the manufacturer needs to coat the adhesive layer 116 first, bond the electroluminescent lamp to the metal key board, and then peel off the transfer paper 102 and tear it away. , It is also necessary to apply a layer of adhesive layer on the lower surface of the metal key board, so that it can be installed on the circuit board of the mobile phone to form a backlit keyboard board. The whole process requires multiple assembly and glue coating by the mobile phone manufacturer, and the process is complicated. And it is easy to lead to unstable quality, so it is necessary to produce a separate product that combines the electroluminescent lamp and the metal key board, and this product is very easy to install on the circuit board, and assemble the electroluminescent lamp and the metal key board for mobile phone manufacturers to the board for convenience
