Foldable Display Cover Openings for Efficient Defect Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices face challenges in efficiently inspecting for defects, which can lead to damage if not detected promptly.
Innovation Solution
A display module design featuring a cover member with protruding holding portions and openings that expose side and rear surfaces of the display unit, allowing for improved inspection efficiency and increased impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a cover member completely covers the display unit for protection, then impact resistance is improved, but inspection efficiency deteriorates due to inability to view side surfaces
Solution Approach 1:
The cover member is segmented with multiple openings (first opening, second opening, third opening) at different locations and orientations. These openings divide the cover into functional zones: some areas provide protection while others enable inspection of specific surfaces (side surfaces, rear surface) without compromising overall protective coverage.
Solution Approach 2:
Different regions of the cover member have different properties: areas with openings provide inspection access while areas without openings provide impact protection. The openings are strategically positioned to expose specific surfaces (side surfaces through first/second openings, rear surface through third opening) while maintaining protection in other regions.
2Productivity
If the cover member is designed with multiple openings for inspection, then inspection efficiency is improved, but structural integrity deteriorates
Solution Approach 1:
Multiple openings are distributed across the cover member rather than concentrated in one area. This segmentation allows inspection access to different surfaces while distributing structural stress across the remaining cover material, maintaining overall structural integrity despite multiple access points.
Solution Approach 2:
The openings are positioned in different spatial dimensions and orientations (first opening for side surface, second opening for opposite side surface, third opening for rear surface). This three-dimensional distribution of openings allows comprehensive inspection access while the cover maintains structural strength through its overall geometry and material properties.
3Ease of operation
If holding portions are added to the cover member for handling, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The holding portions are integrated into the cover member structure rather than being separate components. The first holding portion extends from the first opening region, the second holding portion from the second opening region, and the third holding portion from the third opening region. This merging approach provides handling functionality while maintaining a unified cover structure.
Solution Approach 2:
The cover member serves multiple functions: protection (main body), inspection access (openings), and handling (holding portions). Each holding portion is positioned to facilitate grasping and manipulation of the cover member during inspection and installation operations, adding operational convenience without requiring separate handling mechanisms.

AI summary
A display module includes a display unit including a foldable area and a non-folding area adjacent thereto. A cover member is disposed on a rear surface of the display unit and includes a cover portion covering a portion of the display unit overlapping each of the foldable and non-folding areas. The cover portion has at least one opening defined therein which exposes at least a portion of a side surface of the display unit. A first holding portion extends from the cover portion in a first direction and protrudes to an outside of the display unit. A second holding portion extends from the cover portion in a second direction and protrudes to the outside of the display unit. A third holding portion is spaced apart from the second holding portion in the second direction and protrudes to the outside of the display unit.
