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.
