This utility model discloses an OLED substrate encapsulation assembly, comprising: a substrate, a display functional layer fixedly connected to the top of the substrate, and a cover plate snapped onto the top of the substrate; and a stabilizing assembly, the stabilizing assembly including a frame adhesive, the frame adhesive being fixedly connected to the outer sides of both sides of the display functional layer. This utility model improves the adhesion between the frame adhesive and the substrate by utilizing the strong adhesion between the silicon oxynitride layer and the frame adhesive material, thereby improving the encapsulation efficiency of the frame adhesive. Simultaneously, the combination of slots and blocks enhances stability during the assembly of the substrate and the cover plate, preventing detachment and cracking. The frame adhesive further enhances the stability of the overall device assembly process. Furthermore, the electroactive polymer layer can deform under the influence of an electric field. During encapsulation, by controlling the electric field applied to the electroactive polymer layer, the electroactive polymer layer can use mechanical pressure to expel residual gas from the encapsulation cavity between the display functional layer and the cover plate.
