Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional VR display device structures are used, then hardware and software limitations are maintained, but resolution improvement is prevented
Solution Approach 1:
The pixel array is segmented into first and second pixel arrays arranged in alternating columns. Each pixel array is independently driven by separate data lines (first data lines and second data lines), dividing the driving circuit load into two independent parts. This segmentation allows resolution improvement without overloading the driving circuits, as each circuit only needs to handle half the total pixel count.
2Measurement precision
If more data lines are added to improve resolution, then pixel density increases, but driving circuit load increases
Solution Approach 1:
Adjacent first data lines are electrically connected and adjacent second data lines are electrically connected, merging multiple data lines into fewer independent driving circuits. This merging reduces the number of independent driving circuits needed while maintaining the ability to drive all pixels, thereby improving resolution without proportionally increasing driving circuit load.
3Measurement precision
If sub-pixels are arranged in alternating patterns, then resolution is improved, but manufacturing precision requirements increase
Solution Approach 1:
The first and second pixel arrays are arranged in an asymmetric alternating pattern where first sub-pixels and second sub-pixels occupy different column positions. This asymmetric arrangement, combined with the mirror-symmetrical channel extension directions, creates a regular repeating unit that simplifies manufacturing alignment requirements compared to more complex symmetric patterns.
Solution Approach 2:
Different regions of the display are assigned different sub-pixel types (first or second) based on their column position. Each region has uniform local characteristics, which simplifies the manufacturing process within each local area while achieving high overall resolution through the alternating pattern.
