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 invention relates to a method for sealing glass grit with laser and a laser sealing system; the method comprises: transmitting a laser beam; splitting, by a beam splitter, the laser beam into laser beams longer than pre-splitting spots and having more uniform energy; guiding the laser beams into a chamber for sealing glass grit; focusing and correcting the laser beams to form line laser that irradiates the glass grit which is used to seal a semiconductor device. Point laser in the prior art is processed into line laser having long spots and uniform energy, glass grit is melted by the line laser to seal a semiconductor device, and incomplete seal or seal breakage for an overlap area in laser sealing due to laser energy instability is well avoided.

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] At present, the packaging method of AMOLED (Active Matrix Organic Light Emitting Diode) generally adopts point laser to melt and seal the glass frit (Frit). This type of packaging may have incomplete sealing or cracks in the Overlap area, such as figure 1 with 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. Contents of the invention [0003] The purpose of the present invention is to avoid incomplete sealing or cracking when laser sealing the glass frit. To achieve the above purpose, the present invention provides a laser sealing method. [0004] A method for laser sealing glass frit, comprisin...
