Touch control method for touch panel, touch panel, active stylus for touch panel, and touch display apparatus including touch panel

A touch control method for a touch display apparatus comprising a touch panel and an active stylus, wherein the touch panel comprises a common electrode array and is configured to generate a display, determine a touch input position of a touch input by the active stylus, and determine a touch input pressure of the touch input, the touch control method comprising:

• detecting the touch input;
• generating the display, the generating the display comprising driving at least a first common electrode of the common electrode array to output a display voltage;
• determining the touch input position, the determining the touch input position comprising detecting a first signal transmitted at a first frequency from the active stylus through at least a second common electrode of the common electrode array, and determining the touch input position based on the detected first signal and a position of the at least the second common electrode;
• and
• determining the touch input pressure, the determining the touch input pressure comprising detecting a pressure signal transmitted at a second frequency from the active stylus and determining the touch input pressure based on the detected pressure signal,
• wherein:
• each of the detecting the touch input, the generating the display, the determining the touch input position, and the determining the touch input pressure is performed by the touch panel,
• during a time period of one frame of images, the first signal is detectable for a first time period and the pressure signal is detectable for a second time period, and the second time period is longer than or equal to t1+2t2, t1 being a time for the generating the display, and t2 being a time for transmitting the pressure signal in the second time period.
