Claim:
1. A method of compensating for crosstalk in a touch sensitive display, the touch sensitive display having display pixels for displaying data and touch components for sensing a touch or hover event, the method comprising: during a touch sensing mode of operation, driving the touch components with a stimulation voltage, the touch components generating an output within a frequency band, the output indicative of the touch or hover event; during the touch sensing mode of operation, driving the display pixels with the varying voltage at a modulation frequency, the display pixels causing the crosstalk; wherein the modulation frequency is such as to push at least a portion of the crosstalk out of the frequency band of the output; demodulating the output to isolate the crosstalk therefrom; determining a crosstalk compensation factor based on the isolated crosstalk; and applying the determined crosstalk compensation factor to the output to provide a crosstalk compensated output.
