Method of driving touch display and touch display capable of increasing signal-to-noise ratio
A method of driving touch display includes a switching circuit driving each block of N blocks of a touch panel to display a corresponding image according to a driving signal generated by a liquid crystal driving unit during a first predetermined time within each horizontal synchronization signal period corresponding to the block between two vertical synchronization signals of the touch panel; the switching circuit executing touch scanning on M blocks of the N blocks only corresponding to the block according to touch scanning signals generated by a touch control unit during a second predetermined time within the horizontal synchronization signal period; and the touch control unit receiving and processing a touch scanning result corresponding to each block of the M blocks through the switching circuit during a third predetermined time within the horizontal synchronization signal period, where N and M are integers, and M is smaller than N.
