Abstract
The invention is a method for curing a sealant used to affix two substrates to one another. The sealant requires curing by heat or uv photons. To overcome the shadowing caused by metal patterns, the uv light in the form of laser light is delivered at slant angles without losing light due to strong reflections caused by shallow angles of incidence. Several embodiments are described including a modulation technique for a providing scanned uv beam. Another method utilizes a sufficiently strong pulsed stationary or moving laser beam that can heat the regions of a metallized pattern to provide thermal energy for curing the sealant while providing uv photons through open regions of the metal pattern to access the sealant so as to afford a photolytic cure of a hybrid sealant.
