Abstract
The present invention discloses a method for recognizing multiple active capacitive styluses, a touch control unit, a touch panel, and a touch system. The method includes the steps of: obtaining recognization signals sent by multiple active capacitive styluses, and recognizing coordinates of each active capacitive stylus and its report point removing ghost point coordinates from the report point coordinates in a mutual capacitive mode of a work cycle of a touch panel, to obtain actual coordinates of each active capacitive stylus. The present invention accurately recognizes the specific positions of the multiple active capacitive styluses by eliminating the coordinates of the ghost points and has the advantages of high positioning accuracy and strong user experience.
