摘要： A detecting device and method for a capacitive touch screen is proposed. A plurality of frequency settings is employed. Each frequency setting corresponds to a type of driving mode of a type of driving potential. These frequency settings are used for setting the detecting device for the capacitive touch screen. When the signal-to-noise (S/N) ratio of the signals in the capacitive touch screen is not appropriate, frequency settings are changed by selecting one that yields a more appropriate S/N ratio among the frequency settings. The driving mode includes a single-electrode driving mode in which only a single driving electrode in the capacitive touch screen is driven at a time, and a multiple-electrode driving mode in which multiple driving electrodes are simultaneously driven at a time, and there can be several types of driving potentials.

The conductive strip pattern allows that, when a touch range of each external conductive object on the mutual capacitive multi-touch screen is larger than a predetermined condition, capacitive coupling between each external conductive object and first conductive strip is greater than capacitive coupling between each external conductive object and second conductive strip, such that the proportion of a driving signal flowing out of the first conductive strip via at least one first external conductive object in the external conductive objects and into the second conductive strip via at least one second external conductive object in the external conductive objects decreases as the number of second external conductive objects increases.

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.
