Abstract

See full text

A method for operating an electronic device includes detecting, by a touchscreen controller, a touch point on a touchscreen; determining, by the touchscreen controller, coordinates of the touch point; scaling, by the touchscreen controller, up the coordinates of the touch point to obtain scaled up coordinates by overwriting a reserved portion of a touch event protocol with additional information corresponding to the coordinates of the touch point; reporting, by the touchscreen controller, the scaled up coordinates of the touch point to an application processor; and determining, by the application processor, the coordinates of the touch point with an increased resolution by converting the scaled up coordinates into a floating point value.
