Deformable Display Panel Bridge Area Stress Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses with deformable panels face image distortion due to varying distances between display areas when deformed to fit curved surfaces, leading to displacement and potential rotation of support members.
Innovation Solution
A display apparatus design featuring a first member with a display panel, a support member, and a stopper unit, where the stopper unit selectively contacts the support member to prevent rotation, and a force applicator applies pressure to the bridge area, ensuring minimal displacement and maintaining image clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is deformed to fit curved surfaces, then the display apparatus can be arranged on various shaped surfaces, but the distance between display areas varies causing image distortion
Solution Approach 1:
The display panel is divided into multiple display areas separated by bridge areas. This segmentation allows each display area to be independently supported by support members, enabling the panel to be deformed onto curved surfaces while maintaining local planarity of each display area, thus preventing image distortion.
Solution Approach 2:
Bridge areas are introduced as intermediary elements connecting adjacent display areas. These bridge areas act as mediators that accommodate the deformation and distance variations between display areas when the panel is deformed, while the support members maintain the display areas in substantially planar positions to prevent image distortion.
2Manufacturing precision
If support members are used to maintain display areas, then image clarity is improved, but the support members may rotate when the panel is deformed
Solution Approach 1:
Stopper units are pre-positioned on the substrate in positions that correspond to the deformed state of the display panel. When the panel is deformed onto a curved surface, these pre-positioned stopper units immediately engage with the support members to prevent rotation, without requiring any additional adjustment or action.
Solution Approach 2:
Stopper units serve as intermediary elements between the substrate and the support members. They mediate the interaction by providing a mechanical stop that prevents the support members from rotating when the panel is deformed, thus stabilizing the support members while allowing the overall panel deformation.
3Manufacturing precision
If display areas are kept apart to prevent distortion, then image clarity is maintained, but the bridge areas experience stress during deformation
Solution Approach 1:
The bridge areas are designed as flexible connecting structures that can accommodate the stress and deformation when the display panel is deformed onto curved surfaces. Their flexible nature allows them to bend and stretch without breaking, while still maintaining the separation between display areas to prevent image distortion.

AI summary
A display apparatus includes a first member, a display panel disposed on the first member and including a plurality of display areas arranged to be apart from each other and a bridge area connecting together the display areas apart from each other, a support member disposed on the first member to correspond to each of the display areas and a portion of the bridge area, and a stopper unit disposed on the first member, where the stopper unit selectively contacts with the support member.
