Title: METHOD FOR DETERMINING TARGET WORKING FREQUENCY OF STYLUS, TOUCHSCREEN, AND STYLUS
Abstract:
A method for determining a target working frequency of a stylus, a touchscreen, and the stylus, which relate to the technical field of touch. The method comprises: receiving, by means o a touchscreen, a search signal sent by a stylus and detecting a frequency of the search signal, and determining whether the frequency of the search signal is the same as a target working frequency of the touchscreen (S101); and when the frequency of the search signal is the same as the target working frequency, sending a response signal to the stylus, so as to command the stylus to determine a current working frequency of the stylus as the target working frequency (S102). Compared with the prior art, the method has the advantages of simplicity in use, high reliability and the like.
