Abstract

The invention is a multifunctional capacitive touch system and a control method of the touch display device. The multifunctional capacitive touch system comprises a multifunctional capacitive stylus and a touch display device, and the speaker triggers the multifunctional function. In the case of a capacitive stylus, the multi-function capacitive stylus transmits a first activation signal and a directional sensing signal to the touch display device, so that the touch display device displays a virtual laser spot and enables the touch display. The device controls the moving direction of the virtual laser point according to the direction sensing signal. Since the present invention directly displays the virtual laser spot by the touch display device and does not emit the laser beam, the virtual laser spot is not blocked by other objects, thereby avoiding the shortcomings of not being able to immediately remind the listener of the current key area. At the same time, it can effectively remind the listener of the current focus.
