Description

Technical Field

[0001] The invention relates to the field of OLED display, and in particular to an OLED linear array laser packaging device. Background Art

[0002] OLED stands for organic light-emitting diode, also known as organic electric laser display. OLED display technology has the advantages of large viewing angle and low energy consumption. It uses a very thin organic material coating and a glass substrate. When current passes through, these organic materials will emit light. In addition, the OLED display screen has a large viewing angle and can significantly save electricity. After the evaporation of organic materials on the substrate, the OLED display device needs to be packaged with a cover plate. The existing laser packaging technology uses a single laser beam or multiple laser beams to simultaneously irradiate the encapsulant filled between the substrate and the cover plate and melt and solidify it, thereby isolating moisture and oxygen.

[0003] Currently, when the substrate and the cover are bonded together, since the two are not completely bonded together, residual gas will be unable to be discharged. During the packaging process, electric charges are continuously accumulated on the surface of the sealing structure, which will cause gap discharge between the sealing structure and the internal OLED device, thereby damaging the optoelectronic device.
