Problems solved by technology

This type of packaging may have incomplete sealing or cracks in the Overlap area, such as figure 1 and Figure 2A , 2B
Specifically, the use of point lasers may cause the laser to be unstable due to the acceleration and deceleration of the laser head at the start and end areas of the package, resulting in package failure in this area.

Abstract

The present invention relates to a method and a laser sealing system for laser sealing glass frit, the method comprising: emitting a laser beam; dispersing the laser beam into a laser beam with a longer spot and more uniform energy than before dispersion through a beam splitter; The laser beam is introduced into the chamber used for sealing the glass frit; the laser beam is focused and corrected to form a line laser, and the line laser is irradiated on the glass frit used for sealing the semiconductor components. In the present invention, the point laser in the traditional technology is processed into a line laser with a long spot and uniform energy, and then the semiconductor components are sealed by melting the glass frit through the line laser, which well avoids the overlapping (Overlap) area in the laser sealing process due to laser An incomplete or broken seal caused by energy instability.

Description

Technical field [0001] The invention relates to laser beam processing, in particular to a method for laser sealing glass frit, and also to a laser sealing system. Background technique [0002] The current AMOLED (active matrix organic light emitting diode) packaging method generally uses a spot laser to melt and seal the frit. This packaging method may have incomplete sealing or cracks in the overlap area, such as figure 1 with Figure 2A , 2B . The specific reason is that in the beginning and end areas of the package, the use of a spot laser may cause the laser head to be unstable due to the acceleration and deceleration process of the laser head, causing the package failure problem in this area. Summary of the invention [0003] The purpose of the present invention is to avoid incomplete sealing or cracking during laser sealing of glass frit. In order to achieve the above objective, the present invention provides a laser sealing method. [0004] A method for laser sealing glass ...
