Classification: CPC G | IPC G

Claim 5:
6. A proximity sensing controller, comprising:
a display driver interface circuit configured to:
receive an output vertical sync signal from a display driver configured to drive a display panel according to display information, the display panel defining a sensing region and including a first display area and a second display area, and
retrieve the display information encoded in the output vertical sync signal,
wherein a first display frame rate for the first display area and a second display frame rate for the second display area are set to different frame rates based on respective contents displayed in the first and second display areas;

a proximity sensing circuit configured to generate positional information of an input object based at least in part on a resulting signal received from a sensor electrode disposed in the sensing region; and
a control circuit configured to control an operation of the proximity sensing circuit based at least in part on the display information, wherein a proximity sensing report rate corresponding to a portion of the sensing region corresponding to the first display area is lower than a proximity sensing report rate corresponding to a portion of the sensing region corresponding to the second display area.
