Abstract
A lighting keyboard comprises a first key and a second key, with a gap region between them. A backlight module for the lighting keyboard comprises a lighting board having a light emitting unit, a light guide panel, and a shielding sheet having a light-reducing pattern corresponding to the first key, which are stacked from top to bottom. The backlight module has a colored material layer on the shielding sheet or the light guide panel and vertically overlapping with the gap region. A light of the light emitting unit is guided by the light guide panel to pass through the light-reducing pattern and form a first color light upward from an inner outlet of the first key, and further to pass through the colored material layer and form a second color light different from the first color light upward from an inner outlet and a boundary of the second key.
