  • Patent number: 9317157
    Abstract: A clustered scan method of a capacitive touch device has steps of simultaneously providing driving signals in one driving cycle to multiple driving lines including the (i?j)th drive line to the (i+k)th drive line, and simultaneously providing driving signals in a next driving cycle to the drive lines including some of the drive lines driven in the previous driving cycle with a sum of the driving signal in each driving cycle greater than zero. When the stimulated drive lines include a bordering drive line, the driving lines are determined according to a relationship among i, j and k. Accordingly, the signal to noise ratio of the touch device can be increased and the adverse effect for common ground occurring between a measuring system and a human body can be reduced so that the multi-finger positioning issue can be resolved.

  • Patent number: 8619056
    Abstract: Ghost resolution sensing methods are provided for capacitive touch panels. When ghost is detected involving two points on a capacitive touch panel, for each of the two points, the intersected traces at that one are concurrently charged to sense the capacitance value from either one of the intersected traces, and according thereto, a real point and a ghost point can be distinguished from each other. Alternatively, the intersected traces are crisscross driven by two synchronous and in phase signals or synchronous but out of phase signals, to sense the capacitance values at the two points. Preferably, intersectional calibration is performed in conjunction therewith, to recognize the real points.
