Title: SIGNAL TRANSMITTING METHOD, SIGNAL PARSING METHOD, ACTIVE PEN AND TOUCH SCREEN
Abstract:
The present invention relates to the technical field of electronic information. Disclosed are a signal transmitting method, a signal parsing method, an active pen and a touch screen. In the present invention, the signal transmitting method comprises: the active pen performing frequency modulation on information to be delivered to generate a frequency-modulated signal of the information to be delivered; and the active pen transmitting the frequency-modulated signal of the information to be delivered. Also provided are a signal parsing method, an active pen and a touch screen. The signal transmitting method, the signal parsing method, the active pen and the touch screen provided in the present invention greatly improve the refresh rate and solve the problem that the timing sequence of signal transmission of the active pen and screen terminal detection is complex, and information delivery is time-consuming.
