Embodiment Construction

[0025] Attached figure 1 , Laser sealing methods include:

[0026] S10: Generate parallel laser light. Specifically, a group of parallel laser light is generated by the laser.

[0027] S30: Transform the parallel laser into a deformed laser with a larger beam. Specifically, generally speaking, the beam of the parallel laser generated by the laser is not large enough, and it needs to be reshaped to transform the parallel laser into a deformed laser with a larger beam. It can be understood that the size of the beam can be adjusted according to requirements.

[0028] S50: Display a pattern matching the shape of the packaging material, and the deformation laser forms a matching laser through the pattern. Specifically, for example, a large-size packaging substrate is to be laser packaged, and a pattern matching the shape of the packaging material to be laser-sealed (for example, a pattern reduced in a certain proportion) is obtained in advance, and the deformation laser passes through ...

Abstract

The invention discloses a laser sealing method and system. The method comprises the following steps: generating parallel laser light; converting the parallel laser light into deformed laser light of which the light beam is enlarged; displaying a pattern matched with the shape of an encapsulating material, and forming matched laser light by the deformed laser light through the pattern; reflecting the matched laser light to form encapsulating laser light of which the shape is the same as that of the encapsulating material. The light beam of the parallel laser light is enlarged to obtain the deformed laser; the deformed laser light is used for forming the matched laser light through the pattern matched with the shape of the encapsulating material, the matched laser is reflected to form the encapsulating laser light of which the shape is the same as the encapsulating material, and the encapsulating laser light vertically irradiates on the encapsulating material, so that synchronous heating and synchronous laser sealing are realized.

Description

Technical field [0001] The present invention relates to the technical field of laser control, in particular to a laser sealing method and system. Background technique [0002] OLED (Organic Light Emitting Diode) display technology has attracted attention due to its excellent light-emitting performance and its wide application prospects. OLED has the advantages of high brightness, good color contrast, wide viewing angle, fast refresh speed and low energy consumption. [0003] The organic light-emitting layer and electrodes in the OLED device are very sensitive to oxygen and moisture in the surrounding environment, and will interact with them and deteriorate, thereby greatly affecting the service life of the OLED device. The current sealing method used in OLED (organic light emitting diode) displays is laser frit scanning sealing. The method is to use a sealing glass frit to bond the upper substrate and the lower substrate together, deposit the OLED (organic light emitting diode) o...
