Abstract
An illuminant keyboard and a method thereof are provided. A plurality of protruding walls substantially parallel to each other are disposed on one of an upper surface of the transparent plate, a lower surface of the transparent plate and an upper surface of the planar light source. The protruding walls may be either I-shaped, L-shaped, U-shaped or square-shaped. When the protruding walls are made of an opaque material, the protruding walls can effectively reduce the intensity of the halo light surrounding a transparent keycap. When the protruding walls are made of a transparent material with a designated color, the halo light surrounding the keycap will be modulated with the designated color.
