Abstract

An active pen sensing device can include a plurality of division blocks divided into a matrix along a first direction and a second direction intersecting the first direction, each of which comprises a plurality of sensing cells, a plurality of first sensing lines connected to the plurality of sensing cells of each of the plurality of division blocks along the first direction, a plurality of second sensing lines connected to the plurality of sensing cells of each of the plurality of division blocks along the second direction, and a sensing driving device connected to the plurality of first sensing lines and the plurality of second sensing lines to drive the plurality of division blocks. The sensing driving device can detect the presence or absence of the active pen by activating the plurality of first sensing lines, detect the coordinates of the active pen by activating the plurality of first sensing lines and the plurality of second sensing lines when the active pen is detected, and perform local sensing by activating the first sensing lines and the second sensing lines connected to a specific division block where the active pen is located and first neighboring division blocks when the coordinates of the active pen are detected.
