Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of pixels is increased to achieve high-resolution display, then display resolution is improved, but device complexity and power consumption increase
Solution Approach 1:
The display is divided into normal pixels and interpolation pixels, where interpolation pixels are generated by interpolating light from adjacent normal pixels. This segmentation allows the system to achieve high resolution without requiring every pixel to have full driving circuitry, thereby reducing overall device complexity.
Solution Approach 2:
Interpolation pixels act as intermediaries between normal pixels. Instead of directly increasing the number of independent pixel elements, the system uses interpolation pixels that derive their light output from adjacent normal pixels through interpolation, effectively increasing resolution while avoiding the full complexity of independent pixel structures.
2Measurement precision
If the number of pixels is increased to achieve high-resolution display, then display resolution is improved, but power consumption increases
Solution Approach 1:
The pixel system is segmented into normal pixels that consume full power and interpolation pixels that consume reduced power. By distributing the display function across these segments, the system achieves high resolution while controlling overall power consumption through the lower-power interpolation pixels.
Solution Approach 2:
Instead of providing full driving capability to all pixels, the system provides partial driving capability to interpolation pixels by sharing light output with adjacent normal pixels. This partial action approach reduces the total power consumption while still achieving the desired resolution through the combined output of normal and interpolation pixels.
3Measurement precision
If OLEDoS technology is used to achieve high resolution, then display resolution is improved, but manufacturing complexity increases
Solution Approach 1:
The manufacturing process is segmented into the formation of normal pixels with full driving structures and interpolation pixels with reduced structures. This segmentation allows for simplified manufacturing procedures compared to creating every pixel with complete driving circuitry, while still achieving high resolution through the interpolation pixel network.
