An electrode loop structure of a touch panel mainly extends from I-shaped electrode elements serving as a base, and utilizes the annular conducting chain and gradient chain regularly cascaded together. A discontinuous resistor chain is disposed between the conducting chain and the gradient chain, wherein the conducting chain changes, by adjusting the cascaded length of and the gaps between the electrode elements, the conductor area to generate the trend of voltage drop, so that the conducting chain has the voltage regulating and compensating properties. Meanwhile, the gradient chain may also make the gradient chain have the voltage distributing uniformity by adjusting the lengths of and the gaps between the electrode elements, so that the electrode loop is effectively distributed around the electroconductive substrate to form the homogenized electric field effect, thereby satisfying the narrow-edge design requirement. |
