Problems solved by technology

[0003] At present, during the bending process of flexible OLED screens, the deformation between the various film layers cannot be coordinated, and the interaction between the film layers increases the stress level of the film material during the bending deformation process. The behaviors together lead to the fact that after the screen is bent, it cannot be kept flat when it is unfolded. The resulting wavy display stripes are a major problem that must be overcome in the development of flexible screens.

Abstract

The invention provides a flexible organic light-emitting display and spring assemblies. Film layers are pulled by the spring assemblies one by one so that the film layers can be flat when unfolded andcannot irreversibly deform when folded, lubricating layers are arranged between every two adjacent matched film layers so that the acting force between the adjacent film layers can be reduced, and therefore the flexible organic light-emitting display is flat and free of folds when unfolded.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a flexible organic light emitting display and a spring assembly. Background technique [0002] Foldable mobile phones are a research and development hotspot of flexible electronic products in the future, among which the foldable organic light emitting display (Organic Light Emitting Display, OLED) screen is the most critical component in the foldable mobile phone. [0003] At present, during the bending process of flexible OLED screens, the deformation between the various film layers cannot be coordinated, and the interaction between the film layers increases the stress level of the film material during the bending deformation process. These behaviors together lead to the fact that after the screen is bent, it cannot be kept flat when unfolded. The resulting wavy display stripes are a major problem that must be overcome during the development of flexible screens. Con...
