Flexible Display Module Patterned Window Balancing Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible display modules lack sufficient impact resistance and pattern visibility, which are essential for enhanced portability and usability.
Innovation Solution
The electronic device incorporates a flexible display module with a patterned window featuring multiple patterned portions, each with at least three corners having a predetermined curvature. The curvature of the corners on the upper and lower sides of the patterned window differs, and the distance between patterned portions varies to enhance impact resistance without compromising visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a patterned window is added to improve impact resistance, then the display module's durability is improved, but the pattern may become visually noticeable and affect aesthetic appeal
Solution Approach 1:
The patterned portions are strategically positioned at corner regions of the flexible display module where impact forces are most likely to occur. The curvature radius varies by location, with smaller curvature radii at corners experiencing higher impact risk, providing localized reinforcement where it is most needed while maintaining aesthetic appearance in other areas
Solution Approach 2:
The curvature radius of the patterned portions is precisely controlled within a specific range (0.01mm to 0.05mm) to optimize the balance between impact resistance and visual invisibility. By adjusting this critical parameter, the pattern provides structural reinforcement while remaining imperceptible to the human eye
2Ease of manufacture
If the curvature of all corners is made uniform, then the manufacturing process is simplified, but the optimal impact resistance for different corners is not achieved
Solution Approach 1:
Different curvature radii are assigned to different corners based on their specific impact risk profiles. Corner portions experiencing higher impact forces are given smaller curvature radii for enhanced reinforcement, while other corners have larger curvature radii, creating an asymmetric distribution that optimizes overall impact resistance
3Shape
If the distance between patterned portions is reduced uniformly, then the pattern becomes less visible, but the impact resistance is compromised
Solution Approach 1:
The distances between adjacent patterned portions are differentiated based on local requirements. Regions with higher impact risk maintain larger spacing to ensure adequate reinforcement, while regions where aesthetics are prioritized have smaller spacing to reduce pattern visibility, creating a locally optimized structure
