Abstract
Disclosed is an electronic pen sensing apparatus including an electronic pen sensor disposed at the upper part or the lower part of a display, a heterogeneous sensor disposed at the lower part of the display, a processor electrically connected to the electronic pen sensor, the processor being configured to output a driving signal to the electronic pen sensor, to calculate coordinate information of the electronic pen based on a sensing signal sensed by the electronic pen sensor, wherein the electronic pen sensor is not disposed in a first area corresponding to the heterogeneous sensor, and the processor calculates first coordinate information of the electronic pen based on a first sensing signal sensed by the electronic pen sensor in the case in which the electronic pen is located in a second area.
