Input device having multi-level device and user device including the same

摘要

One or more embodiments provide an input device including a multi-level driver and an operating method thereof. The input device includes a sensor board that includes at least one loop. The input device also includes at least one multi-level driver that includes a plurality of drivers, and is configured to output, to the at least one loop, a signal generated based on signals output from the plurality of drivers.

主权项

1. An input device, comprising:
a sensor board that includes a first loop disposed in a center area of the sensor board and a second loop disposed in an edge area of the sensor board; a first multi-level driver circuit that includes a first set of driver circuits, and is set to output, to the first loop, a first sum signal generated by adding up at least two signals output from the first set of driver circuits; and a second multi-level driver circuit that includes a second set of driver circuits, and is set to output, to the second loop, a second sum signal generated by adding up at least two signals output from the second set of driver circuits, wherein electric power of the second sum signal is greater than electric power of the first sum signal.
