| 摘要 |
In one embodiment, an apparatus for detecting a touch. The apparatus includes a touch sensor that includes a first plurality of electrode lines and a second plurality of electrode lines. The apparatus also includes a touch sensor controller coupled to the touch sensor. The touch sensor controller is operable to apply a respective voltage pulse simultaneously to each of the first plurality of electrode lines, measure a respective signal at each of the second plurality of electrode lines, and detect a touch based on the measurement of the respective signals. |
