摘要： The present disclosure relates to a touch control device and touch determination method thereof. When a processor determines a capacitive coupling variation of a sensing point at a sensing panel of the touch sensitive device is smaller than a predetermined negative threshold or larger than a predetermined positive threshold, the processor then computes from local 2D sensing information of second 2D sensing information measured at the sensing point, to obtain a flatness index, The processor determine that the sensing point is not touched by any external object if the flatness index is between a predetermined flatness index negative reference value and a predetermined flatness index positive reference value that indicates the capacitive coupling amount at the sensing point is changed by the sensing point is not touched by any external object, whereby a false touch control determination due to removing water drop on the touch sensing panel can be prevented.

摘要： The present invention relates to a touch module and a touch screen. The touch module includes a touch panel located on the display module, a main circuit board located outside the casing of the touch screen, a plurality of signal cables connecting the touch panel and the main circuit board, and an equal potential wiring. By setting an equal potential wiring in the touch module to electrically bridge any two signal cables, a short circuit is formed between the shielding layers of the signal cables so that the potentials of different signal cables can be equalized to make the signal cables roughly the same degree of electrostatic or electromagnetic interference from the environment. By making the signals obtained by the signal cables be disturbed to approximately the same degree, the touch module can accurately determine the touch position.
