TWI230957B - Unevenly illuminated keyboard - Google Patents

Abstract

A keyboard having unevenly illuminating effect is provided, which uses luminescence components embedded in the keyboard to provide the light source and a shielding unit placed between the illuminant keycaps and the luminescence components. Said shielding unit determines a light illuminant area under each keycap whereas areas surrounding each keycap are defined as non-illuminant, and hence the light projecting from the light source corresponds to each keycap to generate brightness, thereby creating an unevenly illuminated keyboard in which only keycaps emit light instead of the whole keyboard.
