Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the resolution of display monitors is increased to achieve high brightness and color saturation, then the display quality is improved, but the power consumption rises rapidly and color-mixing occurs between adjacent display units
Solution Approach 1:
The patent divides the display device into multiple independent display units, each surrounded by light shielding structures. This segmentation isolates the light emission from each unit, preventing color-mixing between adjacent units while maintaining high resolution and brightness without increasing power consumption.
Solution Approach 2:
The patent applies light shielding structures selectively at specific locations between adjacent display units where light mixing occurs. This localized approach addresses the color-mixing problem without affecting the overall brightness and color saturation of the display, thereby improving display quality without increasing power consumption.
2Illumination intensity
If the resolution of display monitors is increased to achieve high color saturation, then the display quality is improved, but color-mixing occurs between adjacent display units
Solution Approach 1:
The patent divides the display device into multiple independent display units, each surrounded by light shielding structures. This segmentation isolates the light emission from each unit, preventing color-mixing between adjacent units while maintaining high resolution and brightness without increasing power consumption.
Solution Approach 2:
The patent introduces light shielding structures as intermediary elements between adjacent display units. These structures act as barriers that block light from spilling into adjacent units, thereby preventing color-mixing while allowing each unit to maintain its high brightness and color saturation independently.
3Manufacturing precision
If flexible substrates are manufactured with higher resolution, then the display quality is improved, but the manufacturing process faces difficulties and production limits
Solution Approach 1:
The patent divides the flexible substrate into multiple independent display units with light shielding structures between them. This segmentation simplifies the manufacturing process by allowing each unit to be manufactured and tested independently, reducing the overall manufacturing difficulty while achieving high resolution across the entire flexible substrate.
