Solution Overview
Problem
Conventional display panels face challenges in expanding the display area while maintaining aesthetic appeal and durability, particularly in curved designs where corners are prone to stress and deformation.
Innovation Solution
A display panel design featuring a bendable corner display area with a substrate structure that includes strip portions and spaces, allowing for flexible curvature and reduced stress, along with pixel circuits and display elements arranged across the front, side, middle, and corner areas to enhance image display and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is expanded to include corner areas, then the display coverage is increased, but the structural stress and deformation risk at corners increases
Solution Approach 1:
The substrate is divided into multiple strip portions extending from the front display area into the corner display area, with spaces between adjacent strip portions. This segmentation allows the corner region to flex and bend independently, distributing mechanical stress and preventing deformation while enabling the display area to be expanded into the corner regions.
2Adaptability or versatility
If the substrate is made flexible to enable curved designs, then the adaptability and aesthetic appeal are improved, but the durability and resistance to deformation are reduced
Solution Approach 1:
The substrate exhibits different mechanical properties in different regions: the front display area maintains high strength and rigidity to prevent deformation, while the corner display area incorporates flexible strip portions with spaces between them to enable bending and curvature. This local differentiation allows the display panel to achieve curved designs while maintaining overall durability.
3Adaptability or versatility
If strip portions and spaces are introduced in the corner area, then the flexibility and stress distribution are improved, but the manufacturing complexity increases
Solution Approach 1:
The substrate is segmented into strip portions with spaces between them in the corner display area, creating a flexible structure that can bend and distribute stress. This segmentation is implemented in a localized manner only in the corner regions, while the front display area maintains a conventional continuous substrate structure, thereby achieving flexibility without excessive manufacturing complexity.
