Display apparatus and the sealing method thereof

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.

What is claimed is: 
     
         1 . A display apparatus comprising:
 a substrate comprising a displaying region and a non-displaying region surrounding the displaying region; and   a frit disposed on the non-displaying region to form a 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 glaze it along the loop in a first direction, and a second light beam is applied 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; and   wherein the second direction is different from the first direction.   
     
     
         2 . The display apparatus according to  claim 1 , wherein the first and second light beams 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.   
     
     
         3 . The display apparatus according to  claim 2 , wherein the diameter of each of the first and second light spots is equal to the width of the loop. 
     
     
         4 . The display apparatus according to  claim 1 , wherein the first and second light beams overlap at the start portion of the loop in an overlapping area not less than 50% and not more than 100% of the start portion. 
     
     
         5 . The display apparatus according to  claim 1 , wherein the first and second light beams are applied to the frit at the same moving speed. 
     
     
         6 . The display apparatus according to  claim 1 , wherein the first and second light spots overlap at the end portion of the loop in an overlapping area not less than 50% and not more than 100% of the end portion 
     
     
         7 . A method for sealing a display apparatus comprising:
 providing a substrate which has a displaying region and a non-displaying region surrounding the displaying region;   disposing a frit to form a loop on the non-displaying region, in which the loop surrounds the displaying region and has both a start portion and an end portion not overlapping each other;   providing a heating source configured for generating a first light beam and a second light beam;   providing a converging unit configured for focusing the first and second light beams on the frit to form the first and second light spots, respectively;   applying the first and second light beams at the start portion to glaze the frit at the start portion;   moving the first and second light beams along the loop in a first direction and a second direction, respectively, starting at the start portion and ending up at the end portion, in which the second direction is different from the first direction; and   applying the first and second light beams at the end portion of the loop;   wherein each of the first and second light spots has a diameter larger than or equal to a width of the loop.   
     
     
         8 . The method according to  claim 7 , wherein the heating source comprises a laser or a halogen lamp. 
     
     
         9 . The method according to  claim 7 , wherein the first and second light beams overlap at the start portion of the loop in an overlapping area not less than 50% and not more than 100% of the start portion. 
     
     
         10 . The method according to  claim 7 , wherein the first and second light spots overlap at the end portion of the loop in an overlapping area not less than 50% and not more than 100% of the end portion.
