PACKAGING STRUCTURE OF OLED DEVICE AND PACKAGING METHOD THEREOF

摘要

The present invention provides a packaging structure of an OLED device and a packaging method thereof. The packaging structure of the OLED device includes a substrate (1), an OLED device (2) arranged on the substrate (1), a first barrier layer (3) formed on the OLED device (2), a buffer layer (4) formed on the first barrier layer (3), and a second barrier layer (5) formed on the buffer layer (4). The buffer layer (4) includes water-absorbent particles (41) mixed therein. The present invention uses the buffer that includes water-absorbent particles mixed therein to improve the capability of the packaging structure for blocking moisture so as to effectively extend the lifespan of the OLED device. The packaging method of the OLED device according to the present invention effectively blocks the invasion of moisture, improve the effect of packaging, and effectively extend the lifespan of the OLED device. The method is simple and has good operability.
