Abstract

The invention discloses a flexible display device which comprises a display area and a non-display area encircling the display area, a first flexible substrate, an inorganic layer arranged on the first flexible substrate, and grounding wires arranged on the inorganic layer, wherein the grounding wires are arranged in the non-display area and form a detection circuit; at least two grounding wires are arranged in the non-display area on the same side of the display area at least; the at least two grounding wires comprise at least one first grounding wire and at least one second grounding wire; the inorganic layer is provided with a groove; the first grounding wire is arranged in the groove; the second grounding wire is arranged on the surface of the inorganic layer. According to the flexible display device disclosed by the invention, crack positions can be judged by the detection circuit, whether the cracks exist on the inorganic layer and on the first flexible substrate can be judged, and the detection rate of risk products is improved; meanwhile, since the first grounding wire is positioned in the groove, and the second grounding wire is positioned on the surface of the inorganic layer, the horizontal distance among the various grounding wires can be reduced, and the narrow bezel design of the flexible display device is promoted.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a flexible display device. Background technique [0002] With the continuous development of display technology, flexible display panels will soon become the mainstream in the display field due to their thin, light, bendable, and impact-resistant features. [0003] The flexible display panel includes: a base layer and an inorganic layer, wherein the inorganic layer plays a buffer role. When the flexible display panel is manufactured, the flexible material polyimide (PI) liquid is first coated on the rigid substrate (such as a glass substrate) to form a flexible base layer, and then the inorganic layer, display device and Various wiring, etc. After the flexible display panel is fabricated, it is necessary to separate the flexible display panel from the rigid substrate. During the separation process, due to the stress mismatch between the film layers of the flexible d...
