Abstract
Provided is a laser beam apparatus for sealing a first substrate and a second substrate by irradiating a sealant between the first substrate and the second substrate using a laser beam, the laser beam apparatus including a controller, wherein the controller is configured to defocus the laser beam and to move a scanning central axis of the laser beam across a sealing path of the sealant.
Claims23
A laser beam apparatus for sealing a first substrate and a second substrate by irradiating a sealant between the first substrate and the second substrate using a laser beam, the laser beam apparatus comprising a controller,
- wherein the controller is configured to defocus the laser beam and to move a scanning central axis of the laser beam across a sealing path of the sealant.
A substrate sealing method comprising:
- aligning a central axis of a laser beam to a central line of a sealing path;
- scanning the laser beam along the central line of the sealing path to irradiate the sealing path with the laser beam;
- defocusing the laser beam;
- and
- moving a scanning central line of the laser beam in a direction crossing the sealing path.
