Display Device Support Member with Localized Cross-Sectional Shapes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices are prone to damage and cracking when subjected to external impacts, particularly in bending areas, which can lead to abnormal image display and reduced device reliability.
Innovation Solution
A display device design that incorporates a support member with different shapes at its ends, one in the bending area and the other in the non-bending area, to provide protection to the display panel and minimize damage from external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is made flexible to enable bending and reduce non-display area, then the aesthetic appearance and versatility are improved, but the device becomes more susceptible to external impacts and cracking in bending areas
Solution Approach 1:
The support member is designed with different cross-sectional shapes at different locations: a first cross-sectional shape in the bending area and a second cross-sectional shape in the non-bending area. This local differentiation provides enhanced protection specifically where needed (bending area) while maintaining appropriate support in other areas, resolving the contradiction between flexibility and impact resistance.
Solution Approach 2:
The support member is divided into multiple regions along its length, with each region having a specific cross-sectional shape optimized for its location. The bending area receives specialized protection with a first cross-sectional shape, while non-bending areas have a second cross-sectional shape, allowing the structure to address different mechanical requirements in different segments.
2Ease of manufacture
If the support member has a uniform shape throughout, then the manufacturing process is simpler, but the protection effectiveness varies in bending and non-bending areas
Solution Approach 1:
The support member features a first cross-sectional shape in the bending area and a second cross-sectional shape in the non-bending area, optimizing protection effectiveness for each specific location's mechanical requirements while maintaining a relatively simple overall structure that can be manufactured efficiently.
Solution Approach 2:
The support member employs asymmetric cross-sectional shapes tailored to different locations: the first cross-sectional shape for the bending area and the second cross-sectional shape for the non-bending area. This asymmetric design provides location-specific optimization without requiring completely different support members, balancing manufacturing simplicity with protection effectiveness.

AI summary
A display device includes a display panel comprising a plurality of non-bending areas, and a bending area between the plurality of non-bending areas; and a support member on a rear surface of the display panel, wherein a first end of the support member in the bending area and a second end of the support member in the non-bending area have different shapes.
