1. An electronic device, comprising: a touch panel, comprising a plurality of touch sensors; and a control circuitry, coupled to the touch panel, wherein the control circuitry charges each of the touch sensors according to a preset charge period of the touch sensor and detects a 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,
wherein when the control circuitry adjusts the preset charge periods of the touch sensors, the control circuitry determines a length of the preset charge period of a slowest touch sensor with a largest time constant among the touch sensors according to the preset limit, and the control circuitry determines lengths of the preset charge periods of the other touch sensors according to the length of the preset charge period of the slowest touch sensor and the charge characteristics of the other touch sensors. |
