Abstract
Disclosed is a pointer position detection method for detecting, using a touch sensor including a plurality of sensor electrodes, a touch position indicated by a passive pointer that does not transmit a signal and a pen position indicated by an active pen configured to transmit a downlink signal from a pen electrode disposed in a distal end of the active pen, the pointer position detection method performed by a sensor controller connected to the touch sensor. The pointer position detection method includes: detecting one or more candidate pen positions based on a level of the downlink signal in each of the plurality of sensor electrodes; determining the pen position in an active region at least partially surrounded by a bezel region of a display device from the one or more candidate pen positions; and detecting a gesture performed by the active pen in the bezel region of the display device.
