Curved Display Panel Layout With Variable Modulus Gap Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels struggle to adapt to diverse curved surfaces without causing abnormal display due to gaps or overlapping between deformable regions during stretching or compressing processes.
Innovation Solution
A display panel design with a first display portion and second display portions, where the second portions have a lower Young's modulus than the first, allowing for adjustable deformation to fill gaps and prevent overlapping, featuring sub-pixels and signal lines arranged in specific configurations to maintain image quality on curved surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display panel uses uniform rigid structure for all portions, then manufacturing precision is improved, but the ability to form curved surfaces without gaps or overlapping deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the Young's modulus of different portions of the display panel. Specifically, the second sub-portion is designed with a lower Young's modulus than the first sub-portion, making it more flexible and suitable for deformation when forming curved surfaces, while the first sub-portion maintains higher rigidity for structural stability. This localized variation in material properties resolves the contradiction between manufacturing precision and curved surface formation capability.
2Adaptability or versatility
If the display panel is made flexible to form curved surfaces, then adaptability to different curved surfaces is improved, but stress and potential abnormal displays increase
Solution Approach 1:
The patent resolves the contradiction between adaptability and reliability by applying local quality principles. The second sub-portion is designed with lower Young's modulus to provide the necessary flexibility and adaptability for forming curved surfaces, while the first sub-portion maintains higher Young's modulus to ensure structural stability and prevent abnormal displays. This localized differentiation allows the display panel to adapt to different curved surfaces while maintaining display reliability through the supportive rigid structure.
3Shape
If the second sub-portion has lower Young's modulus to fill gaps, then gap filling capability is improved, but structural strength deteriorates
Solution Approach 1:
The patent resolves the contradiction between gap filling capability and structural strength through local quality differentiation. The second sub-portion is specifically designed with lower Young's modulus to enable effective gap filling when the display panel is deformed into curved surfaces. Meanwhile, the first sub-portion maintains higher Young's modulus to provide the necessary structural strength and support. This localized variation in mechanical properties allows each portion to optimize its function without compromising the overall structural integrity.

AI summary
A display panel includes a first display portion and at least one second display portion. The first display portion includes first sub-pixels and has at least one arc-shaped border. The second display portion is connected to an arc-shaped border and includes first sub-portions and one or more second sub-portions. The first sub-portion includes second sub-pixels, the first sub-portions are sequentially arranged along the arc-shaped border, and in a case where the first display portion and the second display portion are laid on a reference plane, any two adjacent first sub-portions have a gap therebetween. The second sub-portion includes third sub-pixels; at least one second sub-portion is located in a gap between two adjacent first sub-portions and is connected to at least one of the two adjacent first sub-portions. A Young's modulus of the first sub-portion is greater than a Young's modulus of the second sub-portion.
