US 2015/0021151 A1 · LUMINOUS KEYBOARD

Abstract

A luminous keyboard includes a light-emitting element, a proximity sensor, a membrane wiring board, and plural keys. The plural keys are aligned with the plural membrane switches for triggering the plural membrane switches. The light-emitting element is used for providing a light beam to the luminous keyboard. The membrane wiring board has a receiving part for accommodating a signal processing unit of the proximity sensor. In accordance with the present invention, a sensing unit and the signal processing unit of the proximity sensor are used for sensing whether an object is locate near the illuminated keyboard or not. Since the signal processing unit of the proximity sensor is accommodated within the receiving part, it is not necessary to provide an additional accommodation space for accommodating the proximity sensor. Consequently, the luminous keyboard can meet the requirements of slimness and miniaturization.

Dependent claims

A luminous keyboard, comprising:

at least one light-emitting element for providing a light beam to the luminous keyboard;
a proximity sensor comprising a sensing unit and a signal processing unit connected with the sensing unit, wherein when the sensing unit senses that an object enters a sensing range, the signal processing unit issues a sensing signal, wherein in response to the sensing signal, an operating mode of the luminous keyboard is switched;
a membrane wiring board comprising plural membrane switches;
and
plural keys for correspondingly triggering the plural membrane switches,
wherein the membrane wiring board comprises at least one receiving part for accommodating the signal processing unit.
