Abstract: The embodiments of the present invention provide an encapsulation method, a display panel and a display device. The encapsulation method includes: forming a first room temperature bonding layer on the encapsulation region of the array substrate, an OLED device is formed on the display region of the array substrate; forming a second room temperature bonding layer on the encapsulation region of the heat diffuser plate; vacuum laminating the array substrate and the heat diffuser plate such that the first room temperature bonding layer and the second room temperature bonding layer contact with each other and form a sealed structure. The encapsulation method omits the existing encapsulation substrate by using room temperature bonding technology to encapsulate the heat diffuser plate and the array substrate, therefore can not only reduce the overall thickness of the display panel but also further improve the heat dissipation effect.
