Abstract

The present application discloses a composite foam, a flexible OLED display panel and a display device. The composite foam includes a foam and a deformed body on the foam, and the deformed body becomes an arc shape under the condition of receiving an external force, so that in the process of terminal bending (Pad Bending), the deformation The shape of the body changes with the shape of the space enclosed by the foam and the curved portion (especially the shape of the curved portion), and finally fills the space, so that the composite foam is attached to the adhesive layer. It is firmly attached, and no delamination phenomenon occurs, and the product yield of the display panel or the display device is improved. In addition, there is no delamination between the pad area and the composite foam, which improves the product yield of the display panel or the display device.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a composite foam, a flexible OLED display panel and a display device. Background technique [0002] Flexible OLED display panels appear in the mobile phone market with covers, special-shaped (bangs) and narrow borders, and are well received and favored by consumers. [0003] Although the introduction of the Pad Bending process has realized the narrow frame of the OLED display mobile phone, the Pad Bending area needs to be attached with foam (Foam) on the plane and bent, resulting in the narrowness of the Pad Bending side cover. The frame and the curved surface cannot have both. In order to pursue a more beautiful appearance of the mobile phone, the four-sided curved cover plate has been put on the agenda. However, the Pad Bending process at the curved surface has become a difficulty, because during the Pad Bending process, the cover plate is attached to the cover ...
