Abstract

The embodiment of the invention provides a packaging adhesive, a packaging structure and an adhesive spreading device, relates to the technical field of display and aims at solving the problem that acover board is easily peeled off from the edge of a substrate due to the fact that a drying agent is put on a dam adhesive, the problem that a non-display area range is expanded due to the fact that the drying agent is put into an area surrounded by the dam adhesive and the problem that the performance of an OLED device is affected due to the fact that the drying agent is dispersed into a fill adhesive in the prior art. The packaging adhesive comprises a first colloid layer and a second colloid layer coating the first colloid layer; and the first colloid layer comprises colloid and the dryingagent dispersed into the colloid. The packaging adhesive is used for carrying out packaging.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a packaging glue, a packaging structure and a glue coating device. Background technique [0002] Organic Light-Emitting Diode (OLED) is a display lighting technology gradually developed in recent years, especially in the display industry, because of its advantages of high response, high contrast, and flexibility, it is considered to have Wide application prospects. However, since OLED devices will be corroded and damaged under the action of water vapor and oxygen, it is particularly important to choose a better packaging method for OLED devices. [0003] At present, commonly used OLED packaging methods include sheet glue packaging, glass glue packaging (ie, Frit packaging), cofferdam glue and filling glue packaging (ie, Dam and Fill packaging), and the like. Among them, the Dam and Fill packaging methods are specifically shown in Figure 1 (a), coating a circle of cofferdam glu...
