Abstract
A sensing method of touch point includes: detecting an edge region to obtain one or more effective touch point; and determining whether the effective touch point is a valid touch point according to a number of the effective touch point(s) and an area of each of the effective touch point(s). The valid touch point is the effective touch point with the number being equal to 1 and the area satisfying a size condition.
