Abstract

A luminous touch keyboard includes a baseplate, a plurality of keycaps, a plurality of support mechanisms connected between the baseplate and the keycaps, and a keyboard composite electrode module disposed between the baseplate and the keycaps and configured to sense a non-pressing movement over the keycaps and to provide light emitting through the keycaps. The support mechanism supports the keycap to move relative to the baseplate and the keyboard composite electrode module. The keyboard composite electrode module includes a light source circuit and a plurality of electrode matrices arranged along a first direction and a second direction. Two of the electrode matrices adjacent in the second direction are mis-aligned. The light source circuit includes a plurality of light sources disposed in the plurality of electrode matrices in a one-to-one manner, and the position of the light source in the electrode matrix is correspondingly the same.
