Abstract

A display apparatus includes a sealing portion. A method for fabricating the sealing portion includes: irradiating a pulse laser beam onto a deposition target to form the sealing portion at an edge where a substrate and an encapsulation face each, wherein a display unit is formed on the substrate, and the encapsulation is configured to seal the substrate; bonding the substrate and the encapsulation to each other; hardening the sealing portion; and monitoring the sealing portion. Thus, structural strength of the sealing portion is improved.

Claims (18)

1. A method of fabricating a sealing portion of a display apparatus, the method comprising:

irradiating a laser beam at a deposition target spaced apart from a deposition substrate to form a sputtered deposition material,

forming the sealing portion by depositing the sputtered deposition material on the deposition substrate comprising one of a substrate and an encapsulation, the sealing portion formed at an edge at which the substrate and the encapsulation face each other, wherein a display unit is formed on the substrate, and the encapsulation is for sealing the substrate;

bonding the substrate and the encapsulation to each other;

hardening the sealing portion; and

monitoring the sealing portion, wherein the sealing portion is formed through a low temperature process of 40° C. or less.

2. The method of claim 1 , wherein the sealing portion is formed at an edge of at least one of the substrate and the encapsulation.

3. The method of claim 2 , wherein the sealing portion is continuously formed along an edge of the display unit.

4. The method of claim 1 , wherein the forming of the sealing portion comprises:

inserting the deposition substrate comprising one of the substrate and the encapsulation into a chamber to install the deposition substrate on a substrate holder;

installing the deposition target on a target holder that is installed to correspond to the substrate holder; and

forming the sealing portion on the deposition substrate by using particles generated by irradiating the laser beam onto the deposition target from a laser irradiator installed outside the chamber.

5. The method of claim 4 , wherein the laser beam generated from the laser irradiator is a pulse laser beam.

6. The method of claim 4 , wherein the sealing portion is formed in a vacuum chamber,

7. The method of claim 1 , wherein the hardening of the sealing portion comprises irradiating another laser beam from a laser system installed outside the substrate and the encapsulation that are bonded to each other.

8. The method of claim 7 , wherein the laser system comprises a temperature sensor to measure a surface temperature of a part onto which the another laser beam is irradiated, to control an output and a speed of a laser irradiator of the laser system.

9. The method of claim 1 , wherein the monitoring of the sealing portion comprises monitoring a quality of the sealing portion through a laser ablation system.

10. The method of claim 1 , wherein the sealing portion comprises glass frit.
