Claim:
1. A touch panel, comprising a first transparent conductive layer and a second transparent conductive layer opposite to and away from each other; wherein a first voltage signal terminal and a second voltage signal terminal opposite to the first voltage signal terminal are arranged on the first transparent conductive layer, a third voltage signal terminal and a fourth voltage signal terminal opposite to the third voltage signal terminal are arranged on the second transparent conductive layer, and an extension direction of the first voltage signal terminal is perpendicular to an extension direction of the third voltage signal terminal; wherein the second voltage signal terminal and the fourth voltage signal terminal are short-circuited; wherein the touch panel further comprises: wherein the voltage output unit inputs a low voltage of 0V to the second voltage signal terminal and the fourth voltage signal terminal which are short-circuited; wherein the calculation unit calculates the coordinate value of the touch point based on the following formula:
