Display Panel Bending Structure for Reduced Non-Display Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses have a significant visible area of non-display regions that detract from the aesthetic and functional integrity of devices like smartphones.
Innovation Solution
A display apparatus design that incorporates a bending area with a specific radius of curvature (0.2 mm to 0.4 mm) to minimize the visible non-display area by folding the display panel, utilizing protective layers and a spacer to maintain structural integrity and protect the display elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display panel is bent in the bending area to reduce the visible non-display area, then the aesthetic appearance and functional integrity are improved, but the structural integrity and protection of display elements may be compromised
Solution Approach 1:
The display panel is divided into three distinct areas: a first area, a bending area, and a second area. This segmentation allows the bending area to be specifically optimized for flexibility while the other areas maintain structural integrity, resolving the contradiction between reducing visible non-display area and maintaining reliability.
Solution Approach 2:
Protective layers are pre-applied to the display panel before bending, and a filling member is introduced into the bending area to provide cushioning and support. This beforehand protection ensures that the structural integrity and display elements are safeguarded during and after the bending process.
2Shape
If the display panel is bent with a small radius of curvature to minimize the visible non-display area, then the aesthetic appearance is improved, but the manufacturing precision and structural stability become more difficult to control
Solution Approach 1:
A filling member is introduced as an intermediary element into the bending area to facilitate precise control of the bending radius. This filling member enables the achievement of a small radius of curvature (0.2 mm to 0.4 mm) while maintaining manufacturing precision and structural stability during the bending process.
3Reliability
If protective layers and filling members are added to maintain structural integrity during bending, then the reliability is improved, but the device complexity and manufacturing process become more complex
Solution Approach 1:
Multiple protective layers are merged into an integrated protective structure that covers the display panel. The filling member is combined with the bending area design to provide both structural support and enable precise radius control. This merging approach maintains reliability while minimizing the overall complexity compared to adding separate, independent protective components.
