Abstract
An illuminated keyboard includes a keycap, a keycap guiding frame, a light guide plate and a sensing circuit layer, which are sequentially arranged from top to bottom. The keycap guiding frame is used for fixing the keycap and guiding movement of the keycap. The light guide plate is used for fixing the keycap guiding frame and transferring the light beam from a light-emitting element. As the keycap is depressed by the user, the approaching keycap is sensed by the sensing circuit layer, and thus the sensing circuit layer generates a corresponding non-contact key signal.
