Solution Overview
Problem
Existing stretch display screens suffer from image distortion and resolution reduction when stretched, failing to maintain pixel density and display quality.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display screen is stretched to improve flexibility and adaptability, then the stretchability is improved, but the pixel density decreases and image distortion occurs
Solution Approach 1:
The display screen is divided into multiple pixel compensation regions, each containing compensation pixel units that can be independently controlled. This segmentation allows the system to selectively activate compensation pixels in specific areas to maintain overall pixel density during stretching.
Solution Approach 2:
The pixel compensation regions are dynamically controlled based on the stretching state. The detecting unit monitors tensile strength in real-time, and the pixel compensation control unit adjusts the light-emitting areas of compensation pixel units accordingly, enabling the display to adapt dynamically to stretching conditions while maintaining pixel density.
2Manufacturing precision
If the light-emitting area of pixel compensation regions is increased to compensate for stretching, then the pixel density is maintained, but the device complexity increases
Solution Approach 1:
The system employs a feedback mechanism where the detecting unit continuously monitors the tensile strength of the stretching region and transmits this information to the pixel compensation control unit. This feedback loop enables automatic adjustment of compensation pixel light-emitting areas based on actual stretching conditions, simplifying the control process while maintaining pixel density.
Solution Approach 2:
The pixel compensation system operates autonomously by detecting stretching conditions and automatically adjusting compensation pixel light-emitting areas without requiring external intervention. The system self-regulates to maintain pixel density, reducing the need for complex external control mechanisms.
3Manufacturing precision
If compensation pixel units are activated to maintain pixel density, then the display quality is improved, but the energy consumption increases
Solution Approach 1:
Instead of activating all compensation pixel units uniformly, the system selectively activates only the necessary compensation pixels based on the detected stretching state. This partial action approach maintains pixel density in stretched regions while minimizing energy consumption by leaving non-stretched regions unchanged.
Solution Approach 2:
The system changes the light-emitting area parameter of compensation pixel units dynamically based on stretching conditions. By adjusting this parameter rather than uniformly activating all compensation pixels, the system maintains pixel density while optimizing energy consumption according to actual stretching needs.
