[0050]This embodiment introduces how to use the method and device of Embodiment 1 to realize the correction. The so-called correction refers to the correction of the capacitive signal obtained by the capacitive touch screen or touch panel, that is, the above-mentioned environment detection device is applied to an electronic device including a second capacitive detection board, and the second capacitive detection board is used to detect the second capacitive detection Capacitance between a board and an object touched on it, such as a finger. Since the capacitance changes with temperature, humidity or grounding conditions, its stability is poor, and drift phenomenon often occurs. Therefore, the current environmental value can be detected by the method of the above-mentioned embodiment 1, and the second capacitance detection board can be detected. The capacitance value is corrected.
[0051] Such as image 3 shown, including the following steps:
[0052] Step 301, using the fi...
