Abstract
An input sensor including: a sensor including a sensing electrode for sensing a touch input and a pen sensing electrode for sensing a pen input; and a sensor controller configured to acquire a first coordinate based on a touch sensing signal received from the sensing electrode and acquire a second coordinate based on a pen sensing signal received from the pen sensing electrode during a first sensing frame, wherein the first sensing frame includes a first blank period, a touch sensing period for sensing the touch input, and a pen sensing period for sensing the pen input, wherein the first blank period, the touch sensing period, and the pen sensing period are sequentially arranged, and wherein a duration of the first blank period and a duration of the pen sensing period are adjustable.
