Abstract
A detection and updating method of touch system includes: proceeding an ideal base signal measurement to obtain a plurality of ideal base signals under an ideal state; proceeding a raw base signal measurement to obtain a plurality of raw base signals under a raw state; forming a linear relationship related by the ideal base signals and the raw base signals to obtain two coefficients; calculating a plurality of new base signals according to the two coefficients and the ideal base signals; and, proceeding a base signal updating method by the new base signals.
