Abstract
An electronic device and a method for scanning a touch panel of the electronic device are provided. The electronic device includes a touch panel and a control circuitry. The touch panel includes a plurality of touch sensors. The control circuitry is coupled to the touch panel. The control circuitry charges each of the touch sensors according to a preset charge period of the touch sensor and detects the maximum difference in charge characteristics of the touch sensors. The control circuitry adjusts the preset charge periods of the touch sensors according to the charge characteristics of the touch sensors and a preset limit of the preset charge periods of the touch sensors when the maximum difference is higher than a preset threshold.
