Electronic device including narrow bezel and proximity sensing method for the same

A proximity sensing method, the proximity sensing method being performed in an electronic device, the proximity sensing method comprising:

• generating, by a first sensor arranged in a first area which is at least part of a non-display area of a front surface including a display, first sensing information based on a first capacitance sensed by the first sensor;
• generating, by a second sensor arranged in a first side surface adjacent to the first area, second sensing information based on a second capacitance sensed by the second sensor;
• in response to the first sensing information being less than a first threshold value, determining, by a processor, that there is no touch or gesture operation of a user a first object in front of the front surface and that there is no touch or gesture operation of the user proximate to the first sensor;
• in response to the first sensing information being equal to or greater than the first threshold value, generating, by the processor, first compensated sensing information by subtracting the second sensing information from the first sensing information or generating, by the processor, first alternative compensated sensing information by dividing the first sensing information by the second sensing information;
• in response to the first compensated sensing information being less than a second threshold value or the first alternative compensated sensing information being less than a second alternative threshold value, determining, by the processor, that there is no touch or gesture operation of the user proximate to the first sensor and that the first sensing information has been affected by a parasitic capacitance due to the presence of a second object proximate to the first side surface, which has been canceled in the first compensated sensing information or the first alternative compensated sensing information by using the second sensing information;
• and
• in response to the first compensated sensing information being equal to or greater than the second threshold value or the first alternative compensated sensing information being equal to or greater than the second alternative threshold value, determining, by the processor, that a first object is proximate to the first sensor, wherein the first object corresponds to a touch or gesture operation of the user,
• wherein the first side surface is directed to a direction different from a direction to which the front surface including the display is directed.
