To improve the S/N ratio of a pen signal received in a sensor controller, without decreasing the frequency of position detection or increasing the circuit scale of the sensor controller, a method according to the present invention is executed by a sensor controller of an electromagnetic resonance system, and in each of a plurality of pen signal detection periods Tto T, three loop coils LCxto LCxare connected in connection modes having different connection polarities for each pen signal detection period, a result value indicating a level of a pen signal is detected via the three loop coils LCxto LCx, and the level of the pen signal corresponding to each of the three loop coils LCxto LCxis separately acquired by performing a restoration operation according to the connection polarities on a plurality of the result values detected in the respective pen signal detection periods.

Method executed by sensor controller of electromagnetic resonance system, sensor controller, and position detection device

A sensor includes a first substrate on a back side of a display panel, a first coil extending in a first direction at a predetermined angle between 0 and 90 degrees with respect to a long-side direction of the first substrate and including a first long-side portion provided with first and second end portions, a second coil including a second long-side portion extending in a second direction, a first leader line including a first end and a second end, wherein the first end is connected to the first end portion, and the second end is connected to wiring on a second substrate arranged to extend at a right angle toward the outside of the sensor from one side of the first substrate, and a second leader line including first end connected to the end portion and a second end connected to the wiring on the second substrate.

Sensor including a plurality of substrates

A position detection device includes a communication circuit which, in operation, receives, from a stylus including a built-in acceleration sensor, acceleration information detected by the acceleration sensor, and a controller which, in operation, detects a first position indicating a position of the stylus on a touch surface and a second position indicating a position of a finger on the touch surface, and outputs the first position and the second position that have been detected. The controller controls the output of the second position based on the acceleration information received by the communication circuit.
