Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic elements (driving elements, switching elements) are added to enhance display functionality, then the control capability and light emission are improved, but the transparency of the display device decreases
Solution Approach 1:
The patent moves electronic elements from the front surface to the rear surface of the display device, utilizing the depth dimension to resolve the conflict between control functionality and transparency. The integrated circuit unit is positioned on the rear surface, allowing electrical connections to extend through the display panel without blocking the visual field from the front.
Solution Approach 2:
The patent introduces transparent conductive layers and transparent encapsulation materials as intermediaries between the electronic elements and the external environment. These transparent components allow electrical functionality to be maintained while minimizing the visual obstruction, thus preserving display transparency.
2Illumination intensity
If the transparency of the display device is increased, then the aesthetic effect and light transmission are improved, but the contrast of displayed images deteriorates
Solution Approach 1:
The patent applies different transparency characteristics to different regions and components. The display panel itself maintains high transparency for aesthetic purposes, while the integrated circuit unit and electronic elements are positioned in regions where they do not interfere with the primary display area. The transparent encapsulation layer provides localized protection without compromising overall transparency or contrast.
Solution Approach 2:
The patent segments the display device into distinct functional zones: a high-transparency display area for optimal image contrast and aesthetics, and a rear surface area housing the integrated circuit unit for control functionality. This spatial segmentation allows each zone to optimize its specific function without compromising the other.
3Extent of automation
If more electronic elements are integrated into the display device, then the functionality and control precision are improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple electronic elements (driving elements, switching elements, control circuits) into a single integrated circuit unit. This consolidation reduces the number of discrete components and simplifies the overall structure, while maintaining full control functionality and precision through integration.
Solution Approach 2:
The integrated circuit unit performs multiple functions simultaneously: driving the light emitting units, controlling transparency, managing pixel operations, and coordinating display content. This multi-functionality reduces the need for separate dedicated components, thereby simplifying the device structure while enhancing control capabilities.
