A laser irradiation apparatus for bonding a first substrate and a second substrate of a display device by melting a plurality of bonding members disposed between the first and second substrates to define cells when the display device is manufactured, the display device including light emitting elements disposed on a surface of the first substrate such that the bonding members respectively encompass lateral regions of the light emitting elements, the laser irradiation apparatus including a stage on which the first substrate is mounted, a laser oscillation member configured to irradiate a laser beam that melts the bonding members disposed between the first substrate and the second substrate, and a scanner configured to irradiate the laser beam incident from the laser oscillation member onto the bonding members, the scanner being configured to sequentially irradiate the laser beam on portions of the bonding members.
摘要:
A laser beam irradiation apparatus irradiates a laser beam to a sealing unit disposed between a first substrate and a second substrate to seal the first substrate and the second substrate. The laser beam irradiation apparatus includes a laser head for irradiating the laser beam; and a control unit for controlling a drive-velocity and a drive-direction of the laser beam. The laser beam is controlled by the control unit which repetitively performs a backward and forward movement along a first direction, and passes a same position at least twice.

An optical fiber can increase efficiency of a laser source and can uniformly distribute the intensity of laser beam when patterning electrodes using a laser. A plasma display panel uses the optical fiber. The shape of a cross-sectional shape of an inner side of the optical fiber is formed to correspond to an outer rim of a pattern mask. The optical fiber transmits light and is connected to the laser source.
