illuminated keyboard

Abstract

The invention discloses a light-emitting keyboard comprising keys, a light guide plate, an induction circuit layer and light-permeable elastic elements. The light-permeable elastic elements are arranged below the keys and provided with light diffusion parts. The light guide plate and the induction circuit layer are arranged below the light-permeable elastic elements, wherein the induction circuit layer is used for generating a non-contact key switch signal. Light rays conducted in the light guide plate upwardly penetrate through the light guide plate and then pass through the light-permeable elastic elements, and a transmission path of the light rays is changed by the light diffusion parts and then the light rays are evenly projected to the whole key caps. The non-contact type induction circuit layer is applied to induct whether the key caps are pressed by a user or not so that a travel direction is not substantially changed when the light rays from light-emitting elements are upwardly projected to the key caps, and thus the light rays can be evenly projected to the key caps.

Description

Technical field [0001] The invention relates to a keyboard, in particular to a keyboard with a light-emitting function. Background technique [0002] The keyboard is a commonly used computer peripheral device for inputting text or commands to the computer. See figure 1 , figure 1 Show the appearance of the existing keyboard. The existing keyboard 1 has a plurality of keys 10. When the user touches the keys 10 with his fingers, the corresponding signals are generated to the computer to enable the computer to perform key functions. For example, when the key 101 is pressed, symbols such as English letters can be input. When the button 102 is pressed, numbers can be input, and when the button 103 is pressed, various functions can be executed quickly. [0003] Recently, keyboard manufacturers are committed to the development of various keyboards with special functions to meet the various needs of different users. For example, in order to enable users to clearly see the words on the ke...

Problems solved by technology

[0014] The existing luminous keyboard 2 has the following problems. First, the light guide plate 241 is located at the lower layer. easy to control

Furthermore, the elastic member 213 is mainly used to touch the membrane switch circuit 22 to make the upper contact 221a contact the lower contact 222a, so the elastic member 213 must have a protrusion 213a inside, and the shape of the elastic member 213 is restricted and cannot be changed arbitrarily. However, such a shape tends to cause light to project toward directions other than the keycap 211, which seriously affects the brightness of the keycap 211 and makes the keycap 211 uneven in light transmission.
