Patent ID: 11941203
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 11:
12. An electronic device, comprising:
a sensor layer comprising a plurality of cross electrodes extending along a first direction, and a plurality of electrodes extending along a second direction crossing the first direction; and
a sensor driver electrically connected with the sensor layer,
wherein the sensor driver is configured to:
receive a plurality of sensing signals from the plurality of electrodes and the plurality of cross electrodes;
sample each of the plurality of sensing signals at a selection sampling frequency higher than a reference sampling frequency to obtain sampling values;
divide the plurality of sensing signals into a valid signal and a noise signal based on pieces of change data calculated by a difference between sampling values adjacent to each other from among the sampling values; and
calculate intermediate coordinates based on the valid signal.
