SENSOR CONTROLLER, METHOD, AND POSITION DETECTION DEVICE

Abstract: provided is a sensor controller connected to an electro-magnetic resonance sensor disposed to overlap with a display. the sensor controller executes a first operation for detecting, by using the electro-magnetic resonance sensor, an electromagnetic induction pen synchronously with a touch detection operation for detecting a touch made by a passive pointer in a panel surface of the display, and the sensor controller executes a second operation for detecting, by using the electro-magnetic resonance sensor, the electromagnetic induction pen synchronously with pixel driving of the display when the electromagnetic induction pen is detected.
