Protective Cover and Stoppers for Display Bending Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with display modules face defects during bending and transfer due to unprotected bending areas, leading to external impacts and foreign substance exposure.
Innovation Solution
A display device design featuring a protective cover with stoppers and strength reinforcing portions on the window, which limits movement and protects the bending area, including a protective cover with a cover portion, support portions, and double-sided adhesive for secure attachment, to reduce defects during manufacturing and usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display module is bent during assembly or transfer, then the display device can be manufactured, but the bending area is exposed to external impacts and foreign substances causing defects
Solution Approach 1:
The protective cover is attached to the display module before bending or transfer operations. This preliminary protective action ensures that the bending area is already shielded when external impacts or foreign substances might cause damage, allowing the module to be bent safely during manufacturing processes.
Solution Approach 2:
The protective cover acts as an intermediary barrier between the bending area and the external environment. It physically separates the vulnerable bending area from harmful external factors such as impacts and foreign substances, enabling safe manipulation during manufacturing.
2Stability of the object's composition
If the window is secured to prevent movement, then structural stability is improved, but the bending area remains vulnerable without protection
Solution Approach 1:
The protective cover is designed as a separate component that can be independently attached to the display module. This segmentation allows the window to maintain its structural stability through stoppers while the protective cover separately provides reliability by shielding the bending area, with both functions operating independently but complementarily.
Solution Approach 2:
The protective cover integrates multiple functions: it protects the bending area from external impacts, prevents foreign substance exposure, and works in conjunction with window stoppers to provide comprehensive structural stability and reliability during manufacturing and operation.
3Reliability
If a protective cover is added to shield the bending area, then defects are reduced, but the device complexity increases
Solution Approach 1:
The protective cover is designed to provide protection specifically at the bending area where it is most needed, rather than uniformly across the entire display module. This localized approach reduces defects at the critical vulnerability point while minimizing the overall complexity by avoiding unnecessary protective structures in non-vulnerable areas.

Function Achieved in This Case
The solution effectively reduces the number and degree of defects in electronic devices by shielding the bending area from external impacts and foreign substances, enhancing the structural integrity and stability of the display module during bending and assembly.
Implementation Method 1
the protective cover may further include a double-sided adhesive member that affixes the fixing portion to the rear surface of the display module

AI summary
A display device includes a window, a display module on a rear surface of the window and including a non-bending area and a bending area configured to bend at a periphery of the non-bending area, a protective cover on a rear surface of the display module to protect the bending area of the display module, and a stopper coupled with the protective cover to limit a movement of the window.
