Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is extended to include the component area where electronic elements are located, then the displayable area is increased, but the light transmittance and image quality may deteriorate due to the presence of components
Solution Approach 1:
The display panel is divided into a main display area and a component area, with further segmentation into pixel regions and sub-pixel regions. This segmentation allows the component area to be integrated into the display structure while maintaining distinct functional zones, enabling image display in areas previously occupied only by components.
Solution Approach 2:
Different regions of the display panel are assigned different properties: the main display area uses standard pixel structures, while the component area employs transparent or semi-transparent display elements with modified optical characteristics. This local differentiation allows light to pass through component regions while maintaining display functionality.
2Adaptability or versatility
If electronic components are placed in the display area, then functional integration is improved, but the resolution and image quality in those areas may deteriorate
Solution Approach 1:
The patent merges the component area with the display area, integrating electronic components (such as sensors, cameras, or other functional elements) directly into regions that also serve as display areas. This merging allows dual functionality in the same spatial region, achieving both component placement and image display.
Solution Approach 2:
The patent employs multi-layer structures where display elements and components are arranged in different spatial dimensions or layers. This dimensional separation allows both display functionality and component functionality to coexist without compromising resolution, as the components and display elements operate in different spatial planes.
3Illumination intensity
If transparent conductive materials are used for connections in the component area, then light transmittance is maintained, but the electrical connection reliability may be compromised
Solution Approach 1:
The patent uses composite conductive structures that combine transparent conductive materials (such as ITO or IZO) with metal layers or other conductive materials. This composite approach maintains optical transparency while enhancing electrical conductivity and connection reliability through the synergistic properties of multiple materials.
