Foldable Display Module Shielding for Impurity Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices face challenges in maintaining reliability and preventing impurities from entering the display module during repeated deformation, such as folding and bending, which can lead to structural damage and reduced performance.
Innovation Solution
A display module with a shielding member that covers the boundary area between supporting members, allowing it to slide and deform with the panel, while being anchored by a receiving guide member, ensuring the shielding structure remains intact and blocks impurities, using materials like polymeric films and metallic films for flexibility and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a rigid shielding structure is used to block impurities, then impurity blocking is improved, but flexibility and reliability during repeated folding are deteriorated
Solution Approach 1:
The patent applies a flexible shielding member made of thin film material that can bend and deform with the display module during folding operations. This flexible shielding member maintains the impurity blocking function while adapting to the dynamic deformation of the foldable display, preventing structural damage that would occur with rigid shielding structures.
2Reliability
If a flexible shielding member is used to maintain reliability during deformation, then reliability is improved, but the ability to block impurities is deteriorated
Solution Approach 1:
The shielding member is designed with dynamic characteristics, allowing it to slide within a receiving guide member and deform with the panel. This dynamic design enables the shielding member to maintain both flexibility for reliable deformation and effectiveness for impurity blocking through its sliding mechanism that maintains continuous coverage.
Solution Approach 2:
The receiving guide member acts as an intermediary structure that guides and constrains the flexible shielding member. This intermediary component ensures the shielding member maintains proper positioning and sliding motion, enabling it to simultaneously achieve flexibility for deformation and effectiveness for blocking impurities.
3Stability of the object's composition
If the shielding member is fixed rigidly to prevent movement, then structural stability is improved, but the ability to deform with the panel is deteriorated
Solution Approach 1:
The shielding member transitions from a fixed rigid structure to a dynamic flexible structure that can slide and deform. The receiving guide member provides guided movement that maintains structural stability while enabling the shielding member to adapt to panel deformation through controlled sliding motion.

AI summary
A display module provides a panel part, a first supporting member, a second supporting member, a receiving guide member and a shielding member. The panel part includes a pixel array to display an image. The first supporting member is disposed under the panel part. The second supporting member is disposed under the panel part and adjacent to the first supporting member along a first direction. The receiving guide member is combined with the second supporting member. The shielding member covers a boundary area between the first supporting member and the second supporting member, and is combined with the first supporting member, and is allowed to slide on the second supporting member and is partially disposed in a receiving space between the receiving guide member and the second supporting member, and is flexible to be bendable or foldable in response to deformation of the panel part.
