Abstract
Some embodiments of the present disclosure provide a method and a system for transmitting a signal, an active stylus, a touch screen and a readable storage medium. The method for transmitting a signal comprises: receiving a DSSS signal sent by the touch screen through a coupling capacitor formed between the active stylus and the touch screen, where the DSSS signal is a spread-spectrum coded signal to be transmitted; and parsing the received DSSS signal to obtain the signal to be transmitted. The method requires just a small amount of additional hardware resources and low power consumption, and can be well applied to an active stylus touch system.
