Abstract
A touch-screen system including a stylus, a display panel and a touch module is disclosed herein. The stylus includes a magnetic component. The touch-sensing module is disposed within the display panel. The touch-sensing module includes a plurality of sensing units distributed at different locations as an array over the display panel. Each of the sensing units includes a Hall induction plate for sensing a magnetic field established by the magnetic component and forming an induction output voltage. The touch module detects a touch position of the stylus according to the induction output voltages from the sensing units.
