Abstract
A multi-mode operation method for a capacitive touch panel is disclosed. The panel has a plurality of touch cells, and detection values of the plurality of touch cells are obtained by mutual capacitance scan. A normal mode and an insulation mode are provided for situations in which the panel is touched by a finger and a glove, respectively. An insulation determination condition is established for automatically determining glove touch to make the panel enter the insulation mode. In the insulation mode, the criteria for determining touch events can be automatically adjusted, or the detection values around the cells touched can be processed to accurately determine the touch effect when the panel is touched by a glove. In the insulation mode, a condition for determining to leave the insulation mode is also established, so that the touch panel can be smoothly switched between the normal mode and the insulation mode.
