  • Patent number: 9594420
    Abstract: The controlling method for a touch panel is disclosed. The controlling methods includes: executing a waking-up procedure to output a waking-up signal; comparing a measured value of the waking-up signal with a pre-determined threshold value; the touch panel staying in a power-saving mode if the measured value of the waking-up signal is smaller than the positive pre-determined threshold value or larger than the negative pre-determined threshold value; and the touch panel starting a detection procedure if the measured value of the waking-up signal is larger than the positive pre-determined threshold value or smaller than the negative default threshold.

  • Patent number: 9367190
    Abstract: The present invention discloses a method and system for touch signal recognition adapted to be used in a capacitive touch panel or apparatus. In order to achieve an objection of enhancement of a touch signal for recognition and getting rid of noise impact simultaneously, the present invention discloses a touch recognition method that actually includes two different measurement cycles to acquire two different sample voltage values. Consequently, noise impact can be removed by calculation of a sample voltage value difference between two different sample voltage values, at the same time, and the sample voltage value difference can provide a double magnitude as disclosed in the prior art to enhance accuracy for recognizing a user touch input while preventing from influence of noise.
