Synchronized touch input recognition

A method of operating a touch-based device including a touch input sensor overlying a display having a plurality of pixels, the touch input sensor having a plurality of touch regions, each of which overlie an associated set of the pixels of the display, the method comprising:

• updating the pixels, where such updating is controlled by a display controller according to a repeatedly executed sequential schema, during which pixels are updated sequentially row by row during row update periods that are followed by horizontal blanking periods, with a vertical blanking period following update of a last row of pixels;
• passing state information from the display controller to a touch controller configured to recognize selectively applied touch inputs at the plurality of touch regions, such state information specifying a current location of updating thin the sequential schema;
• controlling, with the touch controller, touch input recognition based on the state information.
