Method and device for touch identification, and a touch screen are provided. The method includes: performing an axial scanning on a touch screen, and when a touch region is detected, recording scanning axes with scanning rays shielded; corresponding to the detected touch region, according to axial directions, obtaining sets of intersections of the scanning axes with scanning rays shielded; calculating a confidence level for each of the intersection in each set of intersections; and performing a coordinate fusion to all the sets of intersections which correspond to the touch region based on the confidence levels to obtain positions of the touch region. The device includes a scanning record unit, an intersection unit, a calculation unit and a coordinate fusion unit. In the present disclosure, an effective touch region on a touch screen may be better identified.
