Stretchable Display Panel Layout for Irregular Surface Pixel Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stretchable display apparatuses arranged on locally irregular surfaces exhibit non-uniform pixel arrangements, leading to visible differences in pixel intervals and densities, which degrade image resolution.
Innovation Solution
The display apparatus is designed with distinct pixel and connection areas in different display regions, each with varying elongation rates and structures, ensuring uniform pixel intervals and densities across irregular surfaces by adjusting the elongation states of the display panel and film layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus is arranged on a locally irregular surface shape, then the display apparatus can conform to the object surface, but the pixel intervals become non-uniform leading to degraded image resolution
Solution Approach 1:
The display panel is divided into multiple regions (first display area and second display area) with different elongation rates. Each region is independently designed with specific pixel arrangements and connection area configurations to accommodate different elongation requirements, thereby maintaining uniform pixel intervals across the entire irregular surface
Solution Approach 2:
Different regions of the display panel are assigned different properties: the first display area has a first elongation rate with corresponding pixel density and connection area dimensions, while the second display area has a second elongation rate with adjusted pixel density and connection area dimensions. This local differentiation ensures that each region adapts optimally to its specific portion of the irregular surface while maintaining overall image quality
2Adaptability or versatility
If the display panel is stretched to conform to irregular surfaces, then the display can wrap around objects, but the connection areas between pixels become non-uniform affecting structural integrity
Solution Approach 1:
Connection areas in the first display area are designed with first dimensions suitable for the first elongation rate, while connection areas in the second display area are designed with second dimensions suitable for the second elongation rate. This local adaptation ensures that connection areas maintain appropriate sizes and shapes in their respective regions, preserving structural integrity across the stretched display
Solution Approach 2:
The display panel incorporates flexible connection areas that can dynamically adjust their shape and size based on the local elongation requirements of different regions. This dynamic adaptability allows the connection areas to maintain structural integrity while accommodating the overall stretching of the display to conform to irregular surfaces

Function Achieved in This Case
Maintains consistent pixel intervals and densities, preventing non-uniform pixel arrangements and preserving image resolution when the display apparatus is stretched or contracted over irregular surfaces.
Implementation Method 1
When tensile force is applied, a first elongation rate of the display panel in the first display area is different from a second elongation rate of the display panel in the second display area
