Abstract
A location detection device according to the present disclosure includes an electro-magnetic resonance (EMR) sensor arranged to overlap with a display device, and a sensor controller connected to the EMR sensor. The EMR sensor includes a plurality of loop coils arranged side by side in a first direction of a panel surface. The sensor controller, in operation, detects a location of an electromagnetic induction pen, based on an alternating current generated by using both of a first alternating current output from a first loop coil located proximate one end of the plurality of loop coils in the first direction, and a second alternating current output from a second loop coil located on an opposite side of a center of the panel surface in the first direction from the first loop coil. The accuracy of location detection for an electromagnetic induction pen, performed by using the EMR sensor improved.
