OLED Pixel Arrangement Layout for Aperture and Deposition Balance

The pixel array is segmented into different pixel types (first pixels with quadrilateral shapes, second pixels with hexagonal shapes, third pixels with octagonal shapes) arranged in a specific pattern. This segmentation allows different regions to have different gap characteristics, enabling the overall aperture ratio to be improved while maintaining adequate gaps in critical deposition areas through the specific geometric arrangement of polygonal pixels.

The patent employs asymmetric pixel arrangements where first pixels have quadrilateral shapes, second pixels have hexagonal shapes, and third pixels have octagonal shapes. These asymmetric geometric forms create varied gap distributions that simultaneously achieve high aperture ratio and adequate deposition reliability by optimizing the spatial relationship between adjacent pixels of different types.

The patent transitions from conventional uniform pixel arrangements to a multi-dimensional polygonal pixel structure where first, second, and third pixels with different geometric shapes (quadrilateral, hexagonal, octagonal) are arranged in alternating patterns. This dimensional complexity in pixel geometry enables optimized gap control in multiple directions simultaneously, achieving both high aperture ratio and deposition reliability.

Different regions of the pixel array exhibit different gap characteristics through the use of locally optimized pixel shapes and arrangements. First pixels, second pixels, and third pixels are strategically positioned to create locally adapted gap structures that ensure adequate deposition reliability in critical areas while maximizing aperture ratio in display areas.
