Control apparatus and control method for controlling panel module including touch panel and display panel by referring to level transition of at least one driving signal

A control method for controlling a panel module including a touch panel and a display panel, comprising:

• providing a display driver coupled to the display panel;
• using the display driver to control display operations of the display panel according to a plurality of driving signals;
• providing a touch controller coupled to the touch panel and the display driver;
• and
• using the touch controller to refer to a level transition of at least one driving signal of the driving signals to generate a touch control signal corresponding to a touch sensing output generated by the touch panel;
• wherein the step of setting at least a processing period, during which the touch sensing output is detected, comprises using the touch controller to divide the processing period into at least two time segments that correspond to the level transition of the at least one driving signal, and using the touch controller to further set weighting values for each of the at least two time segments, respectively, and to generate the touch control signal by multiplying the touch sensing output of each time segment by the corresponding weighting values, wherein the weighting values compensate for interference by the driving signals, and a sum of all of the weighting values is 1.
