Abstract:
1. A method for determining scanning times of touch driving pulse in a touch panel, wherein the touch panel comprises a plurality of gate lines and a plurality of data lines for providing display data, a frame period of the touch panel comprises a plurality of gate line scan periods, some of the gate line scan periods constitute a data updating time period and the other of the gate line scan periods constitute a blanking time period, the display data are changed in the data updating time period while unchanged in the blanking time period, the method comprising steps of: judging a current gate line scan period is in which one of the data updating time period and the blanking time period; setting a scanning times of touch driving pulse in the current gate line scan period to be a first value if the current gate line scan period is in the data updating time period; setting the scanning times of touch driving pulse in the current gate line scan period to be a second value if the current gate line scan period is in the blanking time period; obtaining a touch scanning time of performing one times touch driving pulse scanning; obtaining a data coupling time of providing the display data to the data lines in the gate line scan period; and determining the first value and the second value based on the gate line scan period, the touch scanning time and the data coupling time; wherein the first value is different from the second value, and the touch scanning time is non-overlapped with the data coupling time.
