Array Substrate Pixel Layout for Larger Blue OLED Sub-Pixels

The patent applies asymmetry by designing different pixel unit structures for different color sub-pixels. Specifically, the blue sub-pixel uses a first pixel unit structure while red and green sub-pixels use a second pixel unit structure, allowing the blue sub-pixel to have a larger area without requiring all sub-pixels to be enlarged. This asymmetric design enables the blue sub-pixel to compensate for its lower efficiency and lifetime by occupying more area, while the overall aperture ratio is maintained through optimized layout arrangements.

The patent utilizes dimensionality change by arranging pixel units in alternating columns (first and second pixel unit columns) and staggering adjacent pixel units in the row direction. This creates a zigzag or offset pattern that optimizes space utilization in both row and column directions. By transitioning from a simple grid arrangement to a staggered multi-dimensional layout, the patent achieves higher packing density and improves the overall aperture ratio while accommodating the larger blue sub-pixel requirements.

The patent implements asymmetry by creating dedicated first pixel unit structures for blue sub-pixels with larger areas, while red and green sub-pixels use compact second pixel unit structures. This allows the blue sub-pixel to achieve higher efficiency through increased area without compromising overall display quality, as the asymmetric design is balanced by the alternating column arrangement that maintains uniform pixel distribution across the display panel.

The patent employs dimensionality change through the staggered arrangement of adjacent pixel units in alternating columns. This creates a zigzag pattern that optimizes spatial utilization and maintains high packing density. By arranging pixel units in this multi-dimensional pattern rather than a simple grid, the patent achieves both high blue sub-pixel efficiency and maintained display quality through improved overall space utilization and uniform visual distribution.

The patent applies segmentation by dividing the pixel array into two types of columns: first pixel unit columns containing blue sub-pixels with first pixel unit structures, and second pixel unit columns containing red and green sub-pixels with second pixel unit structures. This segmentation allows different structural optimizations for different color requirements while maintaining a regular alternating pattern that simplifies the manufacturing process. The segmented design enables the blue sub-pixels to have larger areas without requiring complex individual customization of each pixel.

The patent implements universality by creating two standardized pixel unit structures (first and second pixel unit structures) that can be repeatedly used throughout the display panel. The first pixel unit structure serves blue sub-pixels, while the second pixel unit structure serves red and green sub-pixels. This universal approach allows the patent to achieve optimized aperture ratios through standardized design patterns rather than custom designs for each pixel, maintaining manufacturing simplicity while improving overall display efficiency and aperture ratio.
