Claim:
1. A touch positioning method for a touch display device, comprising: when it is detected that a touch operation has been made on a touch panel, determining whether the touch operation is effective; when the touch operation is effective, sampling coordinate information about a touch point multiple times to acquire a plurality of initial coordinates of the touch point; performing a grouping calculation on the plurality of initial coordinates of the touch point to determine final coordinates of the touch point, wherein performing the grouping calculation on the plurality of initial coordinates of the touch point to determine the final coordinates of the touch point comprises: dividing horizontal coordinates and longitudinal coordinates of the plurality of initial coordinates of the touch point into N groups, respectively, to obtain N groups of classified coordinates, respectively, N being divisible by a number of sampling times of coordinate information about the touch point; for the N groups of classified coordinates of horizontal coordinates and for the N groups of classified coordinates of longitudinal coordinates: calculating an average value of each group of classified coordinates; calculating a difference between the average values of any two groups of classified coordinates and acquiring an absolute value of the difference; determining two groups of classified coordinates corresponding to a minimum absolute value of the difference; and determining an average value of the plurality of initial coordinates of the touch point recorded in the two groups of classified coordinates as a corresponding component of the final coordinates of the touch point.
