Abstract

The present application provides a touch sensitive system attaching to a transparent material. The touch sensitive system includes an electronic device and a shielding conductive material. The electronic device further includes a touch sensitive screen module having no cover glass and placed behind the transparent material; and a touch sensitive control module coupled to the touch sensitive screen module, having palm rejection function. The shielding conductive material attaches to the transparent material and shields at least part of the touch sensitive screen module. In case an external conductive object approximating or touching the shielding conductive material, the touch sensitive control module determines that the at least part of the touch sensitive screen module is touched by a palm.
