Electroluminescent lamp and its combination with metal keyboard and manufacturing method thereof

Abstract

An assembly of an electroluminescent lamp and a metal key board comprises a substrate, an electroluminescence system printed on one side of the substrate, an insulating protective layer to cover an external surface of the electroluminescence system, a first adhesive layer on the insulating protective layer and a metal key board glued on the first adhesive layer. Wherein, the metal key board is composed of a gasket and a plurality of metal keys. The substrate is made from transparent material. An outer side of the metal key board is arranged with a second adhesive layer. The electroluminescence system is arranged with a transparent conducting layer, an illuminating layer, a first dielectric layer, a back electrode layer, a second dielectric layer and a second conducting layer outwards from one side of the substrate in sequence. In addition, lights emitted by the illuminating layer pass through the transparent conducting layer and the substrate and then are transmitted. The assembly has the advantages of damage resistance, lower noise and easy stickup onto circuit board. The present invention further provides an electroluminescent lamp and its production method.

Description

technical field [0001] The invention relates to an electroluminescence lamp and its combination with a metal key board, and a manufacturing method of the electroluminescence lamp, in particular to an electroluminescence lamp which is not easy to break, has low noise and is easy to be pasted on another electronic component A lamp and its combination with a metal keypad, and a manufacturing method for the electroluminescent lamp. 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 And other products, due to the characteristics of small size, light weight, low temperature, low power consumption, no flicker, and uniform light emission, electroluminescent lamps have gradually replaced traditional light-emitting diode...

Problems solved by technology

[0005] However, when assembling the electroluminescent lamp into an electronic product, an adhesive layer 116 must be applied above the second housing layer 114, and the adhesive layer 116 together with the electroluminescent lamp is bonded to the electronic product. product, and then peel off the transfer paper 102 and tear it away to realize the bonding of the electroluminescent lamp to the electronic product, which is inconvenient to use

And because this electroluminescent lamp is printed by ink as a whole, its strength is relatively poor, and it is easy to be damaged when it is stretched by external force.

On the other hand, when this electroluminescent lamp is applied on a mobile phone (not shown in the figure), it contacts the keys on the mobile phone through the outer surface of the first shell layer 104, and the first shell layer 104 is printed with a layer of insulating ink, its strength is poor, and it is easy to be damaged after long-term use with mobile phones

[0006] Furthermore, after the electroluminescent lamp is powered on with alternating current to drive it to work, the electroluminescent lamp will only have current flowing in one direction inside it at a certain moment, and the current will flow in the opposite direction at the next moment. The electroluminescent lamp emits some noise due to the permanent electromagnetic shock, which will affect the comfort and quality of the call when it is applied on a mobile phone
