Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies face challenges in matching high image collection resolution with display resolution, leading to inefficient use of display pixels and unsatisfactory image display quality, particularly in regions of interest, due to fixed pixel density distribution and limited display capabilities.
Innovation Solution
The method involves adjusting display pixel density unevenly across display units in a display array to provide differentiated pixel density for different regions, allowing for splicing and superimposition of images to enhance local display quality and match collection resolution, using controllable deformed materials and flexible substrates to dynamically adjust pixel density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If display pixel density is uniformly distributed across all display units, then the display system is simple to control and manufacture, but the display resolution and image quality in regions of interest cannot be optimized
Solution Approach 1:
The patent applies local quality by adjusting display pixel density differently for different regions of the display array. Display units corresponding to regions of interest receive higher pixel density, while other regions receive lower pixel density. This allows optimization of display resolution where needed without uniformly increasing complexity across the entire display system.
Solution Approach 2:
The patent implements dynamics by enabling dynamic adjustment of display pixel density based on the content being displayed. The system can switch between different pixel density distributions (e.g., uniform, first non-uniform, second non-uniform) depending on whether the content requires high resolution in specific regions or can tolerate uniform distribution.
2Manufacturing precision
If multiple display units are spliced together to improve overall image display resolution, then the viewing-angle range and resolution are enhanced, but the complexity of coordinating and controlling multiple display units increases
Solution Approach 1:
The patent applies segmentation by dividing the display array into multiple independent display units that can be controlled separately. Each display unit can be independently adjusted for pixel density and content display, allowing the system to achieve high overall resolution through coordinated segmentation while managing complexity through modular control.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting the pixel density parameter of individual display units based on the display content and requirements. This allows the system to optimize resolution parameters for specific regions without changing the physical structure of the entire display array, thereby managing coordination complexity.
3Productivity
If display pixel density is increased to match high image collection resolution, then the utilization rate of display pixels is improved, but the power consumption of the display system increases
Solution Approach 1:
The patent applies local quality by concentrating higher pixel density only in regions where image content requires it, rather than uniformly across the entire display array. This localized approach increases display pixel utilization rate in critical regions while reducing overall power consumption compared to uniform high-density display.
Solution Approach 2:
The patent implements dynamics by adjusting pixel density dynamically based on content requirements. When content does not require high resolution, the system switches to lower pixel density modes, reducing power consumption. When high resolution is needed, the system activates higher pixel density modes in specific regions, optimizing the balance between utilization rate and energy consumption.
