Abstract

This disclosure provides a display apparatus and the sealing method thereof. The display apparatus includes: a substrate having a displaying region and a non-displaying region surrounding the displaying region; and a frit disposed on the non-displaying region to form a closed loop which surrounds the displaying region and has both a start portion and an end portion not overlapping each other; wherein a first light beam is applied to the frit to sinter it along the loop in a first direction, and a second light beam is applied to the frit to sinter it along the loop in a second direction, starting at the start portion and ending up at the end portion; wherein, the second direction is different from the first direction.

Claims

1. A method for sealing a display apparatus comprising:

providing a substrate comprising a displaying region and a non-displaying region;

disposing a frit on the non-displaying region to form a loop, in which the loop surrounds the displaying region and has both a start portion and an end portion; and

providing a heating source configured for generating a first light beam and a second light beam;

applying the first light beam to the frit to glaze it along the loop in a first direction, and applying a second light beam to the frit to glaze it along the loop in a second direction, both of the first light beam and the second light beam starting at the start portion and ending up at the end portion, wherein the second direction is different from the first direction.

2. The method according to claim 1, further comprising:

providing a converging unit configured for focusing on said first light beam and said second light beam on said frit to form a first light spot and a second light spot, respectively.

3. The method according to claim 2, wherein diameters of the first light spot and the second light spot are larger than or equal to the width of the loop.

4. The method according to claim 1, wherein the first light spot and second light spot overlap at the start portion of the loop in an overlapping area between 50% to 100% of the start portion.

5. The method according to claim 1, wherein the first light beam and second light beam are produced by a glazing module which comprises:

a heating source, including a laser or a halogen lamp, generating the first light beam and the second light beam; and

a converging unit configured for focusing the first and second light beams on the frit to form a first light spot and a second light spot, respectively;

wherein each of the first and second light spots has a diameter larger than or equal to a width of the loop.

6. The display apparatus according to claim 1, wherein the first beam and second light beam are applied to the frit at the same moving speed.
