Abstract

Embodiments of the invention relate to the technical field of display, and disclose a flexible display screen and a display device. The flexible display screen comprises a flexible substrate and lightemitting units arranged on the flexible substrate, wherein each light emitting unit comprises a first electrode and a grid layer used for absorbing stress; and the first electrode is integrally embedded into the grid layer. The display device comprises the flexible display screen. According to the embodiments of the invention, compared with the prior art, the grid layer used for absorbing stressis arranged in each light emitting unit, and the first electrode is integrally embedded into the grid layer, so that when the flexible display screen is bent, grids in the grid layer can release stress, and the stress is prevented from being gathered in the first electrode, and thus the stress bearing capacity of the first electrode is improved, and the risk that the first electrode is broken or stripped from other film layers is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a flexible display screen and a display device. Background technique [0002] Flexible displays are favored by many consumers because of their thinness, flexibility, and good mechanical properties. The first electrode (eg, anode or cathode), as an important device in a flexible display screen, is usually formed of a material with weak elasticity, which has poor bending ability and adhesion. During the bending process of the flexible display screen, the stress and tension on the first electrode cannot be released, and will accumulate in the first electrode, causing cracks in the first electrode or weakening of the bonding force between the first electrode and other film layers. After that, the stress when the flexible display screen is bent will continue to accumulate in the first electrode, which eventually causes the first electrode to be cracked or ...
