Abstract:
A driving method adapted to a touch-sensing display apparatus is provided. The touch-sensing display apparatus includes a display panel and a touch panel. The driving method includes following steps. I scan signals are sequentially sent to drive the display panel to receive a plurality of data signals. M driving signals are sequentially sent to drive the touch panel to generate a plurality of sensing signals during a sensing period. The mth driving signal is synchronized with the ith scan signal, wherein 1≦i≦I and 1≦m≦M. The touch panel is delayed by a predetermined time period within each pulse width of the M driving signals for generating the sensing signals. Furthermore, a touch controller is also provided.
