Illuminated module and keyboard thereof

An illuminated module, comprising:

• a light source assembly, comprising a light-emitting component, the light-emitting component being configured to emit light;
• a light guide plate, on a traveling route of the light, and having a surface and a microstructure, the microstructure being configured to change a propagation direction of the light incident on the microstructure toward the surface;
• a filter, located on the surface, and having a first area and a second area, the first area and the second area corresponding to the microstructure, wherein the first area has a first filter characteristic, the second area has a second filter characteristic, and the first filter characteristic is different from the second filter characteristic;
• and
• a light-shielding sheet, on an other side of the filter opposite to the light guide plate, and having a transparent opening, the transparent opening corresponding to the microstructure;
• wherein the light guide plate has a first opening, the filter has a second opening, and the light-shielding sheet has a third opening, wherein the first opening, the second opening, and the third opening vertically correspond to each other to form a through hole.
