Abstract:
The invention provides a surface capacitive touch panel and an electronic device, said surface capacitive touch panel comprising: a resistive film, on which an electrode setting area divided into at least two layers is set; and a plurality of conductive electrodes, set in said electrode setting area; said plurality of conductive electrodes including at least one set of electrodes; wherein, said set of electrodes includes: a first strip electrode; a second strip electrode, in parallel with said first strip electrode, but in a different layer; a third strip electrode, in parallel with said first strip electrode, but in a different layer; said second strip electrode and said third strip electrode being located on the same side of said first strip electrode; a fourth strip electrode, both ends of which are connected with said first strip electrode and said second strip electrode, respectively; and a fifth strip electrode, both ends of which are connected with said first strip electrode and said third strip electrode, respectively. The invention enhances the linear degree of the electrical field applied to the resistive film, thereby enhancing the positioning accuracy.
