Supporting Structure for Flexible Display Bending Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices are prone to damage in bending areas due to the lack of a supporting structure, leading to reduced product yield.
Innovation Solution
A display device with a supporting structure, such as thermosetting glue, rubber, or silicone, is used to fill the bending space between the backplates, providing support to the bending area of the display panel and preventing damage when bent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is made flexible to achieve narrow frame, then the frame width is reduced and design flexibility is improved, but the bending area becomes prone to damage and product yield decreases
Solution Approach 1:
A supporting structure is pre-installed in the bending area of the display panel before the device is assembled and put into use. This supporting structure acts as a cushioning element that prevents damage to the bending area when the device is bent, thereby resolving the contradiction between flexibility and damage resistance.
Solution Approach 2:
The display device is segmented into different functional areas: a bending area that can be flexed and a non-bending area that remains rigid. The supporting structure is specifically placed in the bending area to provide localized support, allowing the device to achieve narrow frame through flexibility while maintaining reliability in the bending region.
2Device complexity
If no supporting structure is provided in the bending area, then the device structure is simple and manufacturing is easy, but the circuit in the bending area is vulnerable to damage
Solution Approach 1:
The supporting structure is installed in advance in the bending area to provide protective cushioning for the circuit. This simple yet effective solution prevents circuit damage without requiring complex structural modifications, thus resolving the contradiction between device simplicity and circuit protection.
3Reliability
If the bending area is supported during bending, then product yield is improved, but additional materials and manufacturing steps are required
Solution Approach 1:
The supporting structure is integrated into the manufacturing process as a pre-installation step. By installing the supporting structure beforehand, the device achieves improved product yield through protected bending areas, while the manufacturing process remains relatively simple and scalable.

AI summary
A display device and a method of manufacturing the same are provided. The display device includes a backplate, a display panel, and a supporting structure. The backplate includes a first backplate and a second backplate. The display panel includes a first non-bending area, a second non-bending area, and a bending area. The first backplate is configured to support the first non-bending area. The second backplate is configured to support the second non-bending area. The bending area is bent toward the backplate to form a bending space. The supporting structure is filled in the bending space to support the bending area of the display panel.
