Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple components (sensors, display areas) are integrated in the display panel, then functionality and versatility are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The display panel is divided into distinct functional regions: a main display area with high-resolution subpixels, component areas with sensors, and peripheral areas with pixel circuits. This segmentation allows each region to be optimized independently for its specific function while simplifying the overall design and manufacturing process.
Solution Approach 2:
The patent utilizes vertical layering to integrate multiple functions. Different components (subpixels, sensors, pixel circuits) are arranged in separate layers and regions, allowing high integration without increasing planar complexity. The connection wiring systematically links these vertically-stacked components.
2Illumination intensity
If transparent conductive materials are used for connection wiring, then light transmittance is improved, but electrical conductivity and signal transmission quality may deteriorate
Solution Approach 1:
The connection wiring is constructed as a composite structure combining transparent conductive materials (such as ITO or IZO) with metal layers (such as aluminum or silver). This composite design achieves both high light transmittance from the transparent material and excellent electrical conductivity from the metal layer, resolving the trade-off between optical and electrical performance.
3Manufacturing precision
If pixel circuits are spaced apart from subpixels, then manufacturing precision and alignment are improved, but connection wiring length and signal loss increase
Solution Approach 1:
While pixel circuits are spatially separated from subpixels in the planar layout to simplify manufacturing and alignment, the patent compensates for the increased connection distance by implementing an optimized multi-layer wiring architecture. This systematic connection approach minimizes signal loss despite the longer wiring paths required by the spaced arrangement.
