Abstract
An illuminated keyboard comprises a fixing sheet, a membrane switch circuit module, a supporting plate, a light guide plate, a sensing circuit, a sensing chip, a light-emitting element, and an illumination circuit board. The sensing circuit is formed on the fixing sheet or the membrane switch circuit module. The sensing chip and the light-emitting element are disposed on the illumination circuit board. In addition, the sensing chip is accommodated within corresponding openings of the fixing sheet, the membrane switch circuit module, the supporting plate and the light guide plate. The illuminated keyboard uses the sensing circuit and the sensing chip to sense the presence of an object. Since the illuminated keyboard does not need an additional space to accommodate the sensing circuit and the sensing chip, the illuminated keyboard can meet the requirement of slimness.
