Claim 0:
1. A display driver, comprising:
a driver circuit configured to drive a display panel according to display information, the display panel defining a sensing region, wherein the display panel includes a first display area and a second display area, and wherein driving the display panel comprises setting a first display frame rate for the first display area and a second display frame rate for the second display area, wherein the first display frame rate is higher than the second display frame rate, and wherein the first and second display frame rates are set based on respective contents displayed in the first and second display areas; and
a sensing controller interface circuit configured to transmit an output vertical sync signal to a proximity sensing controller 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, 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;
wherein the output vertical sync signal comprises encoded display information, wherein the encoded display information comprises an encoding of the display mode.
