Abstract
The electrodes (7) and the contact zones (15) are structured in a film of a transparent conductive oxide (TCO), deposited on a transparent support (1) possibly coated with an intermediate film (3), while being separated by dielectric spaces (9) formed by nano fissures (11) obtained by UV radiation and passing through the TCO film. A protective film (13) can coat the electrodes (7) and the dielectric spaces (9).
Claims13
A transparent substrate with invisible electrodes, the transparent substrate including:
- (a) a transparent support;
- and
- (b) a transparent conductive film deposited on the transparent support,
- wherein the transparent conductive film includes invisible electrodes having invisible contact zones, structured with contours separated by non-conductive spaces, wherein the non-conductive spaces include nano fissures formed in the conductive film so as to interrupt electrical conductivity between neighbouring electrodes, and so as to form the invisible electrodes and the invisible contact zones, and wherein the nano fissures have a maximum width of about 500 nanometers.
