Abstract
An encapsulating glue film coating system and a transfer roller thereof, and a method of forming an encapsulating glue film are provided. The encapsulating glue film coating system comprises: a support platform configured to carry a display panel to be encapsulated; a glue liquid storage device configured to provide a glue liquid; a glue liquid input device mounted on the support platform and configured to receive the glue liquid from the glue liquid storage device; and a transfer roller configured to receive the glue liquid from the glue liquid input device. The transfer roller is configure to transfer glue liquid to a coating roller and comprises: a roller body; an absorbing layer disposed around the roller body, the absorbing layer having a plurality of micropores communicating with external environment; and a transfer layer disposed around the absorbing layer for transferring glue liquid to a coating roller, wherein the transfer layer is provided with a plurality of first through-holes, so as to allow impurities to enter the micropores in the absorbing layer. With the encapsulating glue film coating system, glue liquid can be uniformly applied onto the display panel.
