Patent ID: 8786558

Claim:
A control apparatus for controlling a panel module including a touch panel and a display panel, comprising: a display driver, coupled to the display panel, for controlling display operations of the display panel according to a plurality of driving signals; and a touch controller, coupled to the touch panel and the display driver, for referring 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 touch controller divides a processing period, during which the touch sensing output is detected, into at least two time segments that correspond to the level transition of the at least one driving signal, and the touch controller further sets weighting values for each of the at least two time segments, respectively, and generates 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.
