Abstract

The invention provides a flexible folding display device, which comprises a flexible display screen, a hinge component for bending the flexible display in at least one bendable area, and a stress buffer structure which is used for buffering stress on the edge of the bendable area of the flexible display screen, wherein the flexible display screen is provided with the at least one bendable area; the hinge component is arranged on the edge of the bendable area of the flexible display screen; the stress buffer structure is arranged in the bendable area of the flexible display screen; the stress buffer structure comprises an elastic buffer part and a hard limiting part; the elastic buffer part is arranged in a mode of clinging to the edge of the flexible display screen and is used for conducting elasticity deformation under the stress on the edge of the flexible display screen; and the hard limiting part is arranged at the outer side of the elastic buffer part and is used for limiting theelastic buffer part. According to the flexible folding display device provided by the invention, a problem that components become invalid due to stress concentration of the flexible display screen onthe edge of the bendable area can be relieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible folding display device. Background technique [0002] With the development of flexible folding display technology, flexible folding display products, especially display products with small curvature radius, have the problem of poor reliability in the bending area. Among them, the existing flexible folding display products mainly include two types of flexible display screens, the frameless design and the hard frame design, and the folding is realized by setting hinges at the edge of the bending area of ​​the flexible display screen. However, these two designs inevitably have the phenomenon of stress concentration on the edge of the display screen and the AA area (effective display area). The internal TFT (thin film transistor) packaging structure, GOA wiring and flexible substrate inorganic layer have a great risk of failure, resulting in poor reliability in t...
