Title:
BACK FILM LAYER, FLEXIBLE DISPLAY PANEL AND FLEXIBLE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/174052
Kind Code:
A1
Abstract:
A back film layer (30), a flexible display panel (100) and a flexible display device (200). The back film layer (30) is used for supporting and protecting a flexible substrate (10) and comprises a deformation portion (33); the deformation portion (33) is provided with grooves (330) at a bendable position of the back film layer (30); the flexible display panel (100) includes the flexible substrate (10), an organic light-emitting material layer (20) and the described back film layer (30); the organic light-emitting material layer (20) is disposed above the flexible substrate (10) and the back film layer (30) is attached below the flexible substrate (10); the flexible display device (200) includes the flexible display panel (100); and the back film layer (30) is provided with the grooves (330) at the deformation portion (33) to limit the curvature of the back film layer (30) at a bending position. The flexible display panel (100) utilizes the described back film layer (30) and the flexible display device (200) utilizes the described flexible display panel (100), thereby preventing excessive bending of the flexible display panel (100) and protecting the flexible display panel (100) and the flexible display device (200), and the lifespans of the flexible display panel (100) and the flexible display device (200) are prolonged.
