Abstract
A multi-mode operation method for a capacitive touch panel includes the steps of: using an initial mutual capacitance value of the panel as a reference value; obtaining a new mutual capacitance value as an original value after the initial step; comparing the original value with the reference value to obtain a detection value; comparing a current detection value with a previous detection value to obtain a first comparison result; when a touch cell has a detection value smaller than 0 if any of other touch cells in the vertical direction and the horizontal direction of the touch cell has a detection value greater than an effective touch standard value, obtaining a calculated value according to the detection value of the touch cell and an absolute value of the touch cell, as the detection value of the touch cell; and selecting between a normal mode and a waterproof mode as the operation mode according to the first comparison result and the detection values of all the touch cells.
