Abstract

A proximity-sensing panel includes a substrate panel, one or more proximity-sensing unit and one or more sensing circuit. The proximity-sensing unit is formed on the substrate panel. The proximity-sensing unit senses motions of an object to generate a proximity-sensing signal accordingly. The sensing circuit receives the proximity-sensing signal and generates a control signal to initiate a proximity touch control.

a substrate panel;

a plurality of proximity-sensing units, formed on the substrate panel, the proximity-sensing unit sensing a motion of an object and generating a proximity-sensing signal; and

at least one sensing circuit, electrically connecting the proximity-sensing unit to receive the proximity-sensing signal and generating a control signal accordingly to initiate a proximity control.

2. The proximity-sensing panel of claim 1, wherein the proximity-sensing unit is selected from the group consisting of a capacitive proximity-sensing unit and an inductive proximity-sensing unit.

3. The proximity-sensing panel of claim 2, wherein the capacitive proximity-sensing unit is selected from the group consisting of a self-capacitance proximity-sensing unit and a mutual-capacitance proximity-sensing unit.

8. The proximity-sensing panel of claim 1, wherein the proximity-sensing units are formed on a top surface of the substrate panel, on a bottom surface of the substrate panel, or both the top and bottom surfaces of the substrate panel.

9. The proximity-sensing panel of claim 1, wherein an arranged pattern of the proximity-sensing units formed on the substrate panel is selected from the group consisting of rectangular arrangement, crisscross arrangement, concentric-circles arrangement, hexagon arrangement, circular arrangement and hexagon arrangement.

10. A proximity-sensing panel, comprising:

a substrate panel;
