Flexible Display Panel Supporting Teeth for Misalignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible display panels suffer from unsatisfactory supporting effects due to assembly errors between the supporting body and the supporting layer, leading to misalignment and inadequate support for the flexible base layer during bending.
Innovation Solution
A flexible display panel design featuring a supporting layer with a bending area containing supporting teeth that contact each other to provide support, and an avoiding space that accommodates assembly errors between the supporting body and the first and second areas, ensuring reliable support even with misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a supporting body is used to support the bending portion of the flexible base layer, then the supporting effect is improved, but assembly errors cause misalignment between the supporting body and the supporting layer, resulting in inadequate support
Solution Approach 1:
The supporting layer is segmented into multiple supporting teeth (first supporting tooth, second supporting tooth, third supporting tooth) distributed across the bending area. This segmentation allows each tooth to independently contact and support the flexible base layer, ensuring that even if the supporting body is misaligned, at least some supporting teeth will effectively support the bending portion.
Solution Approach 2:
The supporting teeth are designed with specific dimensional parameters (length, width, spacing) that allow them to accommodate assembly errors. The teeth extend in the first direction and are spaced to create overlapping support zones, ensuring reliable support regardless of minor misalignments between the supporting body and supporting layer.
2Reliability
If the supporting body is positioned to support the bending portion, then support is provided, but assembly errors cause the supporting body to be offset from the supporting layer, resulting in blocked supporting teeth and unreliable support
Solution Approach 1:
The supporting teeth are pre-positioned on the supporting layer before the supporting body is assembled. This preliminary arrangement ensures that the supporting teeth are already in place to contact and support the flexible base layer, and their positioning is designed to accommodate potential misalignments of the supporting body.
Solution Approach 2:
The supporting teeth act as intermediaries between the supporting layer and the flexible base layer. They transfer the supporting force from the supporting structure to the flexible base layer, ensuring that even if the supporting body is misaligned, the supporting function is maintained through the teeth's contact with the bending portion.
3Reliability
If multiple supporting teeth are used to improve support reliability, then the supporting effect is enhanced, but the structure becomes more complex and the assembly process more difficult
Solution Approach 1:
Multiple supporting teeth are merged into a single integrated supporting layer structure. The first, second, and third supporting teeth are all part of the same supporting layer, forming a unified structure that provides distributed support without requiring separate assembly steps for each tooth, thus maintaining simplicity while improving reliability.

AI summary
A flexible display panel and a display apparatus, the flexible display panel includes: flexible base layer; display part; packaging layer; supporting layer, including first area, bending area and second area, first area being connected with the second area via the bending area, bending area including at least two supporting teeth; supporting body located at a side of flexible base layer facing away from display device; when bending area is in flattening state, reserved space is formed between adjacent supporting teeth; when bending area is in bending state, flexible base layer, first area, supporting body, and second area are stacked in direction perpendicular to first area, adjacent supporting teeth contact with each other to provide supporting force to flexible base layer, supporting teeth together with first and second area form avoiding space, in direction perpendicular to the first area, projection of avoiding space is within projection of bending area.
