Subpixel Layout for Blue Aperture Gain Without Color Mixing

The patent transitions from a conventional arrangement where subpixels are separated in the plane to a configuration where the blue subpixel extends into the vertical dimension by overlapping with the green subpixel. This dimensional change allows the blue subpixel to achieve a larger aperture ratio without causing color mixing, as the overlapping regions are controlled to prevent color contamination while maximizing light emission area.

The blue subpixel is positioned to overlap and partially contain the green subpixel in the vertical arrangement, creating a nested configuration. This nesting allows the blue subpixel to utilize the space above the green subpixel, effectively increasing its aperture ratio without encroaching on the horizontal space needed to prevent color mixing with adjacent subpixels.

By arranging the blue subpixel to overlap vertically with the green subpixel rather than placing it adjacent in the horizontal plane, the patent increases the blue subpixel's aperture ratio without causing color mixing. This vertical arrangement allows the blue subpixel to emit more light (higher aperture ratio) while the controlled overlap prevents color contamination, thereby extending the display's service life.

The patent applies different spatial arrangements to different subpixels based on their specific requirements. The blue subpixel is given a larger vertical overlap with the green subpixel to maximize its aperture ratio and service life, while the red and green subpixels are positioned to prevent color mixing. This localized optimization of subpixel arrangement achieves both extended service life and color accuracy.
