Abstract:
A touch panel, sequentially comprising: a conductive layer, a dielectric layer; and at least one layer of touch electrodes, which comprises multiple first electrodes in parallel to a first axis and multiple second electrodes in parallel to a second axis, wherein the first and the second electrodes connects to a touch sensitive processing apparatus, respectively, wherein the touch sensitive processing apparatus detects an external object approaching or touching the touch panel via the first and the second electrodes, wherein the conductive layer is closer to the external object than the at least one layer of touch electrodes.
