Abstract
This present invention relates to bus bar configurations and fabrication methods of non-rectangular shaped (e.g., triangular, trapezoidal, circular, pentagonal, hexagonal, arched, etc.) optical devices. The optical device comprises a first side, a second side, and a third side adjacent to the second side and two bus bars spanning a portion of the optical device.
Claims16
A method of fabricating an optically switchable device on a non-rectangular substrate, the method comprising:
- (a) receiving at a laser tool the non-rectangular substrate having disposed thereon one or more layers of the optically switchable device;
- and
- (b) directing a laser spot according to two or more non-rectangular laser patterns onto a region at the periphery of the optically switchable device along two straight edges of the non-rectangular substrate to remove at least one of the one or more layers of the optically switchable device from the region without re-orienting the non-rectangular substrate as it passes through the laser tool, wherein the two straight edges meet at a corner that is not a right angle.
