Abstract

The invention provides an encapsulation substrate, an OLED display panel and an encapsulation method thereof. A guiding channel for guiding the encapsulation glue is formed by the first insulation pads after arranging multiple first insulation pads on the encapsulation substrate; the encapsulation glue can diffuse along the guiding channel in the encapsulation process of the encapsulation substrate and the paired box substrate, so that the encapsulation glue can diffuse according to a preset direction and path. The flowing direction of the encapsulation glue is controllable, the fluidity of the encapsulation glue is improved to some extent, and the uniformity of the encapsulation glue filing is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a package substrate, an OLED display panel and a package method thereof. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) devices have become a very Competitiveness and prospects for next-generation display technologies. The organic light-emitting materials and cathode materials used in OLED devices are particularly sensitive to water and oxygen. Too much humidity or too high oxygen content will affect the service life of OLED devices. In order to effectively block the influence of water and oxygen on OLED devices, it needs to be encapsulated, such as Figure 1a As shown, the encapsulation glue 2 is dropped between the array substrate 3 and the encapsulation substrate 1 to block water and oxygen in the air, and the array substrate 3 and the encapsulation substrate 1 are bonded and fixed with the encapsulation glue to achieve sealin...
