Electronic device and method for controlling touch sensing signals and storage medium

An electronic device, comprising:

• a housing including a first plate and a second plate positioned opposite the first plate;
• a display positioned between the first plate and the second plate;
• a touch sensing panel positioned between the display and the first plate, spaced apart from the display by an air gap, and including a plurality of first conductive lines extending in a first direction and a plurality of second conductive lines extending in a different direction from the first direction as viewed from the first plate and crossing the plurality of first conductive lines;
• a wireless communication circuit;
• a processor functionally connected with the display, the panel, and the wireless communication circuit;
• and
• a memory functionally connected with the processor, wherein the memory stores instructions that, when executed by the processor, cause the processor to:
• detect an external object above or near the first plate;
• in a first operation, alternately use a first detection scheme and a second detection scheme, the first detection scheme independently detecting variations in capacitances of the plurality of first conductive lines and the plurality of second conductive lines during a first time period, and the second detection scheme providing voltages to the plurality of first conductive lines and measuring voltages at the plurality of second conductive lines during a second time period;
• and
• in a second operation, either (i) alternately use a modified first detection scheme and the second detection scheme or (ii) use the second detection scheme alone.
