Abstract
Disclosed herein are methods for welding a first substrate and a second substrate, the method comprising bringing the first and second substrates into contact to form a substrate interface, and directing a laser beam operating at a predetermined wavelength through the second substrate onto the substrate interface, wherein the first substrate absorbs light from the laser beam in an amount sufficient to form a weld between the first substrate and the second substrate. The disclosure also relates to glass and/or glass-ceramic packaging and OLED display produced according to the methods disclosed herein.
