摘要：The present invention discloses a proximity sensing apparatus and a method thereof. The proximity sensing apparatus comprises a panel, a first light-emitting unit, a second light-emitting unit and a sensing unit. The panel comprises a plurality of transparent areas. The first light-emitting unit is located at one side of the panel and emits a plurality of first light signals through one of the transparent areas. The second light-emitting unit is located at the same side as the first light-emitting unit of the panel and emits a plurality of second light signals through one of the transparent areas. The sensing unit is located at the same side as the first light-emitting unit of the panel and senses the reflected first light signals or the reflected second light signals reflected by an object. Wherein, the sensing unit is closer to the first light-emitting unit than to the second light-emitting unit.
