Touch panel

摘要

A touch panel includes dummy electrodes, disposed in a transmit electrode layer or a receive electrode layer whichever is below an isolation layer. In one embodiment, an anti-reflective layer includes at least one composite refractive-index three-layer structure. In another embodiment, the receive electrode layer is disposed below the isolation layer, and the receive electrode layer and the dummy electrodes are electrically coupled to a same electric potential.

1. A touch panel, comprising:
an anti-reflective layer including at least one composite refractive-index three-layer structure; a transmit layer, an isolation layer and a receive layer, disposed below the anti-reflective layer, the isolation layer being disposed between the transmit layer and the receive layer; and a plurality of dummy electrodes disposed in the transmit layer or the receive layer whichever is located below the isolation layer; wherein the anti-reflective layer comprises, from top to bottom, a first low-refractive-index layer, a high-refractive-index layer and a second low-refractive-index layer, wherein a refractive index of the high-refractive-index layer is higher than refractive indices of the first low-refractive-index layer and the second low-refractive-index layer.
