Abstract
Disclosed herein are glass articles coated on at least one surface with an electrochromic layer and comprising minimal regions of laser damage, and methods for laser processing such glass articles. Insulated glass units comprising such coated glass articles are also disclosed herein.
Claims21
An electrochromic glass article comprising:
- a glass substrate comprising a first surface, an opposing second surface, and one or more edges, wherein at least one or more of the one or more edges comprises a laser-cut edge;
- and
- an electrochromic coating disposed on at least a portion of the second surface, and comprising at least two electrically discontinuous regions, each having a contour,
- wherein the two electrically discontinuous regions are separated by a laser-modified discontinuity line having a width from 0.1 μm to 25 μm,
- wherein the electrochromic coating comprises a laser damaged peripheral region directly adjacent to the laser-cut edge, the laser-damaged peripheral region having a width of less than 0.1 mm, and
- wherein the contour of at least one of the at least two electrically discontinuous regions is non-linear.
