Claim:
1. A driver circuit for a touch sensitive display device, the display device comprising a panel including a plurality of touch electrodes, data voltages being applied to pixels of the display device during a first display period and a second display period of a predetermined period and not being applied to the pixels of the display device during a first non-display period and a second non-display period of the predetermined period, the driver circuit comprising: circuitry to provide touch scan signals to the touch electrodes, wherein the circuitry is enabled to provide the touch scan signals to the touch electrodes for a first duration in both the first and the second non-display periods over the predetermined period in a first touch driving mode; and wherein the circuitry is enabled to provide the touch scan signals to the touch electrodes for a second duration in the first non-display period but not provide the touch scan signals during the second non-display period over the predetermined period in a second touch driving mode, the second duration being shorter than the first duration.
