Embodiment Construction

[0025] combined with figure 1 , laser sealing methods include:

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

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

[0028] S50: Display a pattern matching the shape of the packaging material, and the deformed laser passes through the pattern to form a matching laser. Specifically, for example, to perform laser encapsulation on a large-sized encapsulation substrate, a pattern matching the shape of the encapsulation material that needs to be laser-sealed (for example, a pattern that is scaled down to a certain ratio) is o...

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 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 been valued due to its excellent luminous performance and wide application prospects. OLED has the advantages of high brightness, good color contrast, wide viewing angle, fast refresh rate and low energy consumption. [0003] Both the organic light-emitting layer and the electrodes in the OLED device are very sensitive to oxygen and moisture in the surrounding environment, and will interact with it to degrade, thereby greatly affecting the service life of the OLED device. The current sealing method used in OLED (Organic Light Emitting Diode) displays is laser glass frit scanning sealing. In this method, the upper substrate and the lower substrate are bonded together using a sealing frit, OLED (organic light emitting diode) is deposited on the first s...
