Abstract

The present disclosure relates to a touch technology, and more particularly, to a touch panel and a manufacturing method thereof. The present invention discloses a touch panel comprising a touch region, a first peripheral region at the first side of said touch region, a second peripheral region at the second side opposite to said first side, a plurality of first axial electrodes and second axial electrodes that intersect with each other diagonally to limit peripheral routing in the two peripheral regions, a plurality of peripheral first lead-wires disposed at the first peripheral region, and a plurality of second lead wares disposed at the second peripheral region. A manufacturing method of a touch panel is also provided.

Dependent claims

A touch panel having a touch region, a first peripheral region, a second peripheral region, a third peripheral region and a fourth peripheral region, wherein the touch panel comprises:

at least one first axial electrode and at least one second axial electrode that diagonally intersect with each other on the touch region, wherein the first axial electrodes and the second axial electrodes are mutually insulated, and wherein the first peripheral region and the second peripheral region are respectively situated on a first side and a second side opposite to the first side of the touch region;
a plurality of the first peripheral lead-wires disposed on the first peripheral region and electrically connected with the first axial electrodes and the second axial electrodes;
and
a plurality of the second peripheral lead-wires disposed on the second peripheral region and electrically connected with the first axial electrodes and the second axial electrodes;
wherein the third peripheral region and the fourth peripheral region are respectively situated on a third side and a fourth side opposite to the third side of the touch region, further wherein the peripheral lead-wires are not disposed on the third peripheral region and the fourth peripheral region.
