Abstract
A backlight keyboard module includes a keyboard portion and a light emitting portion located on the keyboard portion. The keyboard portion includes a baseboard, a keycap movable up and down relative to the baseboard, and a circuit board depressed by the up and down movements of the keycap to output signals. The light emitting portion has a shading plate located beneath the keycap and a light emitting element to provide light. The shading plate has an opening corresponding to the keycap to allow light of the light emitting element to pass through and project to the keycap. Thus the keyboard only illuminates light on the keycap location in a non-uniform manner to highlight the location of the keycap to improve keystroke accuracy.
