摘要： The invention discloses a full screen driven detection. A driving signal is simultaneously provided to all first conductive strips arranged in parallel in a first direction in a touch screen, and mutual capacitive signals are detected from all second conductive strips arranged in parallel in a second direction. The mutual capacitive signals can be used for determining whether an external conductive object coupled to the ground is touching or approaching the touch screen or not even if water or other conductive object not coupled to ground is on the touch screen. When the driving signal is simultaneously provided to all conductive strips arranged in the first direction, the driven signal is also simultaneously provided to a plurality of guarding conductive strips. The guarding conductive strips, the first conductive strips and the second conductive strips are exposed and separated from each other.

摘要： A method and device for analyzing positions are disclosed. In sensing information, at least one position is determined according to a first characteristic of a touch related sensing information. The sensing information also has a touch related sensing information with a second characteristic, which is opposite to the first characteristic. The touch related sensing information with the second characteristic is neglected or filtered. In addition, another method and device for analyzing positions are disclosed. An AC signal is provided through a pen, and a first characteristic of a touch related sensing information corresponding to a finger is opposite to the second characteristic of the touch related sensing information corresponding to the pen. The first characteristic and the second characteristic can be used to distinguish the touch of the finger from the touch of the pen or for palm rejection.
