ACTIVE STYLUS, ACTIVE STYLUS-BASED TOUCH CONTROL SYSTEM, AND TOUCH CONTROL METHOD

摘要

An active stylus, an active stylus-based touch control system, and a touch control method, pertaining to the technical field of touch control. The active stylus comprises a main body (10) and a signal transmission module provided at a tip (5) of the main body (10). The signal transmission module is used to transmit a first signal, such that a touch screen acquires a contact position between the active stylus and the touch screen according to the first signal. An inclination angle detection structure is further provided in the main body (10), and comprises a signal receiving module and a processing module. When the signal transmission module transmits the first signal, the signal receiving module receives the first signal synchronously, and the processing module acquires an inclination angle of the main body (10) according to a strength of the first signal received by the signal receiving module. As a distance between the signal transmission module and the signal receiving module increases, the strength of the first signal received by the signal transmission module decreases, and the inclination angle of the main body (10) decreases, wherein the inclination angle is an angle between the main body (10) and a plane where the touch screen is located.
