Embodiment Construction

[0035] figure 1 , figure 2 and image 3 They are schematic cross-sectional views of the keys of the first, second and third preferred embodiments of the electroluminescence keyboard of the present invention. To clarify, figure 1 , figure 2 and image 3 Although there are differences in the structure, shape and configuration of the components in each figure, the components in each figure can be replaced with the corresponding components in other figures to obtain other embodiments, so the keys applied to the membrane switch keyboard are examples but not limited to figure 1 , figure 2 and image 3 shown in . figure 1 It is a schematic cross-sectional structure diagram of the first preferred embodiment of the electroluminescent keyboard according to the present invention. The button 10 includes a bottom plate 112 , a membrane switch structure 110 , an electrode layer including a first electrode 106 a and a second electrode 106 b , an electroluminescent elastic member 1...

Abstract

The invention relates to an electroluminescent keyboard. The keyboard comprises a plurality of membrane switch structures, a plurality of keycaps, a plurality of electroluminescent elastic elements and an electrode layer, wherein the electroluminescent elastic elements are positioned between the keycaps and the membrane switch structures; and the electrode layer is arranged between the electroluminescent elastic elements and the membrane film switch structures and electrically connected with the electroluminescent elastic elements. When current is introduced into the electrode layer or an electric field is applied to the electrode layer, the electroluminescent elastic elements are electrically stimulated to give out light. The electroluminescent keyboard has the advantages that a local area on the keyboard can be controlled to give out light, and the cost of luminous keys is saved.

Description

technical field [0001] The invention relates to a luminous keyboard, in particular to an electroluminescent keyboard. Background technique [0002] In recent years, due to the rapid development of the information industry, many users may use portable information devices, such as notebook computers or personal digital assistants, in different environments. In a low-light environment, users may not be able to clearly see the numbers and characters marked on the keyboard keys, making operations difficult, and in severe cases, may even cause visual impairment due to barely recognizing the key marks. Therefore, the launch of the luminous keyboard can improve the inconvenience of using the keyboard in places with insufficient light. What's more, through different lighting configurations, the information device using the lighting keyboard can be made to look more beautiful and thus increase its sales. [0003] However, most luminous keyboards require a light source and a backligh...
