Fusion sealing equipment using laser

Abstract

Disclosed is a fusion sealing apparatus using a laser, which emits a laser beam to a frit interposed between a pair of opposing substrates and seals an internal space separated by the pair of opposing substrates and the frit, and includes: Laser output unit, fiber bundle unit, transport unit and controller. The laser output unit outputs a laser beam. The fiber bundle unit includes a plurality of optical fibers and emits the laser beam to the frit by allowing the laser beam to propagate through some of the plurality of optical fibers. The transport unit transports the optical fiber bundle unit and includes an encoder for sensing a position of the optical fiber bundle unit. The controller receives a signal from the encoder of the transport unit, thereby controlling the laser output unit to transmit the laser beam only through the optical fiber arranged at a position corresponding to the shape of the frit.

Description

technical field [0001] The present invention relates to a fusion sealing apparatus using a laser, and more particularly, to a fusion sealing apparatus using a laser in which a laser beam propagated through some optical fibers selected from among a plurality of optical fibers is emitted for sealing with frit . Background technique [0002] As a display device capable of emitting light by itself, an organic light emitting display device has the advantages of wide viewing angle, good contrast ratio, and fast response speed, but due to oxidation of electrode materials caused when water or oxygen is introduced into the organic light emitting display device from the surrounding environment, Peeling, etc., have problems such as short lifetime, low luminous efficiency, and deterioration of luminous color of the organic light-emitting display device. [0003] Therefore, when an organic light emitting display device is manufactured, the organic light emitting display device has gener...

Problems solved by technology

[0006] However, the conventional fusion sealing apparatus using a laser processes the frit 12 while moving a single laser beam L propagating through an optical fiber in the direction in which the frit 12 is applied, and thus has the disadvantage of prolonging the time taken to process the entire frit 12. question

In addition, since the path of the frit 12 becomes long due to the increased demand for large-sized televisions or similar organic light-emitting display devices, the conventional frit sealing method has problems of prolonging the time it takes to process the entire frit 12, and Significantly reduced production efficiency as the single laser beam fired at the frit is moved to melt and harden the frit
