Abstract:
1. A touch panel with a central induction region and a peripheral region surrounding the central induction region, the touch panel at least comprising an upper electrode portion, a lower electrode portion and a plurality of partition elements sandwiched between the upper electrode portion and the lower electrode portion, the upper electrode portion comprising: an upper substrate located in both the central induction region and the peripheral region; a first signal induction layer located in both the central induction region and the peripheral region, and directly covering the upper substrate in the central induction region; and a first circuit layer located in the peripheral region only, directly covering the upper substrate in the peripheral region, and sandwiched between the upper substrate and the first signal induction layer, wherein the first circuit layer and the first signal induction layer are electrically connected with each other, and an impedance value of the first circuit layer is lower than an impedance value of the first signal induction layer wherein the first signal induction layer integrally comprises: a first part located in the peripheral region only, and directly contacted with the first circuit layer; a second part located in the central induction region only, and directly contacted with the first circuit layer and the upper substrate, and remaining a vertical distance with the first part in altitude; and a first slope portion coupled with both the first part and the second part.
