Abstract
A method for determining a target operating frequency of a stylus, and a touch screen and a stylus thereof are disclosed, pertaining to the field of touch technologies. According to embodiments of the present application, a touch screen receives a search signal sent by the stylus and detects the frequency of the search signal, and judges whether the frequency of the search signal is equal to a target operating frequency of the touch screen; and if the frequency of the search signal is equal to the target operating frequency, the touch screen sends a response signal to the stylus, whereupon the stylus determines a current operating frequency thereof as the target operating frequency. As compared with the related art, the method has the advantages such as simple use, high reliability and the like.
