Flexible display panel, method for forming the same and adhesive application device for the method

A method for forming a flexible display panel, wherein the flexible display panel comprises a cover plate layer and a screen film layer, and the screen film layer comprises a plurality of film layers, wherein the method comprises:

• attaching the plurality of film layers sequentially onto one side of the cover plate layer;
• and applying an adhesive into a gap between an edge of an outermost film layer of the screen film layer relative to the cover plate layer and the cover plate layer;
• wherein the screen film layer comprises a polarizer, a display film, a back film and a heat dissipation layer sequentially laminated one on another onto the cover plate layer in a direction away from the cover plate layer,
• prior to applying the adhesive into the gap between the edge of the outermost film layer of the screen film layer relative to the cover plate layer and the cover plate layer, the method further comprises:
• bending the cover plate layer and the screen film layer, wherein the polarizer, the display film, the back film and the heat dissipation layer each comprise a first bending portion and a first non-bending portion, the bent cover plate layer comprises a second bending portion and a second non-bending portion, and an edge of the screen film layer and an edge of the cover plate layer are arranged adjacent to the first bending portion of the screen film layer and the second bending portion of the cover plate layer respectively;
• wherein the applying the adhesive into the gap between the edge of the outermost film layer of the screen film layer relative to the cover plate layer and the cover plate layer comprises:
• applying the adhesive into a gap between an edge of the heat dissipation layer and the cover plate layer in such a manner that the adhesive covers each of edges of the polarizer, the display film, the back film and the heat dissipation layer.

An adhesive application device for a method for forming a flexible display panel, wherein the flexible display panel comprises a cover plate layer and a screen film layer, and the screen film layer comprises a plurality of film layers laminated one on another at one side of the cover plate layer, wherein the adhesive application device comprises a position capturing unit and an adhesive application mechanism, the position capturing unit is configured to obtain position information about an edge of an outermost film layer of the screen film layer relative to the cover plate layer and directly or indirectly transmit the position information to the adhesive application mechanism, and the adhesive application mechanism is configured to apply an adhesive into a gap between the edge of the outermost film layer of the screen film layer relative to the cover plate layer and the cover plate layer;

• wherein the screen film layer comprises a polarizer, a display film, a back film and a heat dissipation layer sequentially laminated one on another onto the cover plate layer in a direction away from the cover plate layer, and the adhesive covers each of edges of the polarizer, the display film, the back film and the heat dissipation layer;
• wherein the polarizer, the display film, the back film and the heat dissipation layer each comprise a first bending portion and a first non-bending portion, the cover plate layer comprises a second bending portion and a second non-bending portion, and an edge of the screen film layer and an edge of the cover plate layer are arranged adjacent to the first bending portion of the screen film layer and the second bending portion of the cover plate layer respectively.
