Abstract
A power-saving touch pad apparatus includes a control unit, a proximity sensing unit, an electric charge induction unit, a touch pad driving-operation unit, and a touch pad unit. The electric charge induction unit is formed by a sputtering process. The electric charge induction unit informs the proximity sensing unit when the electric charge induction unit inducts electric charges. The proximity sensing unit informs the control unit. The control unit is configured to control the touch pad driving-operation unit to wake up the touch pad unit. The electric charge induction unit informs the proximity sensing unit when the electric charge induction unit does not induct electric charges. The proximity sensing unit informs the control unit. The control unit is configured to control the touch pad driving-operation unit to control the touch pad unit to enter a power-saving mode.
