Display Panel Support Module with Spacer-Mediated Joint Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices with multi-joint structures can experience defects due to stress applied when joints contact each other without gaps, leading to uneven stress distribution and potential damage to the display panel.
Innovation Solution
A display device design featuring a support module with joints spaced apart and spacers made of materials like polyurethane or acrylic polymer, which absorb stress and maintain a consistent distance between joints, preventing contact and subsequent panel defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If joints are placed close together to provide continuous support, then support coverage is improved, but stress concentration increases causing display panel defects
Solution Approach 1:
A spacer member is introduced as an intermediary component between adjacent joints to control their relative positioning. The spacer maintains a predetermined gap that prevents stress concentration while ensuring continuous support coverage across the display panel, thereby resolving the contradiction between support area and stress concentration.
2Object-affected harmful factors
If joints are spaced apart to reduce stress, then stress on display panel is reduced, but support continuity is compromised
Solution Approach 1:
The spacer acts as a mediator that enables joints to be spaced apart for stress reduction while maintaining support continuity. By controlling the gap distance, the spacer ensures that joints remain positioned to provide continuous support coverage without causing stress concentration on the display panel.
Solution Approach 2:
The spacer controls the spatial parameter (gap distance) between joints to optimize both stress distribution and support continuity. By maintaining a predetermined gap, the system achieves the optimal balance between reducing stress on the display panel and ensuring continuous support coverage.

AI summary
A display device includes a display panel comprising a first area and a second area located on a side of the first area in a first direction, a panel storage that accommodates the display panel therein, and a support module that supports a bottom of the display panel and assists a sliding operation of the display panel in the first direction. The support module comprises a first support member overlapping the first area, and a second support member overlapping the second area, the second support member comprising joints spaced apart from each other and spacers having an elastic modulus and disposed between the joints.
