Abstract
An electronic pen sensing device includes: a substrate including a sensing region and a first sub sensing region, the first sub sensing region having a width smaller than a width of the sensing region; a first closed loop line disposed along edges of the sensing region and wound N times in a first rotation direction from a first node to a second node, and disposed along edges of the first sub sensing region and wound M times in a first rotation direction from the second node to the first node; and a controller configured to calculate a location of an electronic pen based on a first induction current which is output through the first node, wherein N and M are positive integers.
