Abstract:
A method for operating an electronic device, including: determining that a touchscreen is in a low frequency display (LFD) mode, determining whether a self-sensing scan was performed in a previous frame of a plurality of frames; after determining, a self-sensing scan was performed in the previous frame, determining a current duration of time corresponding to a current frame based on a previous duration of time corresponding to the previous frame, the previous frame being a frame immediately preceding the current frame; determining, whether the current duration of time is greater than the previous duration of time; and after determining that the current duration is greater than the previous duration, performing a self-sensing scan after the current duration of time, the current duration of time being measured from a beginning of the current frame, the current duration of time having a duration less than a duration of the current frame.
