Abstract
Disclosed are an illuminated touchpad including a protection layer, a touch module, and a Parallax-Barrier light source module. The touch module is disposed between the protection layer and the Parallax-Barrier light source module. The Parallax-Barrier light source module has a Parallax-Barrier pattern or is used to produce the Parallax-Barrier pattern. The Parallax-Barrier light source module further has multiple patterns and produces multiple illuminated patterns by the patterns, or the Parallax-Barrier light source module directly produces the illuminated patterns. By the Parallax-Barrier pattern, lights of the illuminated patterns pass through the touch module and the protection layer to form multiple stereoscopic images.
