Pixel Arrangement Structure for Smoother White Display Boundaries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The square arrangement of RGB sub-pixels in display panels leads to serrated or stepped display issues when displaying white light, affecting the display quality, particularly in flexible and vehicle-mounted displays.
Innovation Solution
A pixel arrangement structure with central and peripheral sub-pixels of the same color, where each sub-pixel has multiple vertex angles, allowing separate control to mitigate serrated display by turning on peripheral sub-pixels within the desired display region and turning off those outside it, optimizing the display boundary.

1Ease of manufacture
If square RGB sub-pixels are arranged in a conventional grid pattern, then the manufacturing process is simple, but serrated or stepped display lines appear when displaying white light
Solution Approach 1:
Each pixel is segmented into a central sub-pixel and multiple peripheral sub-pixels (typically 3-5 sub-pixels) arranged radially around the center. This segmentation allows independent control of each sub-pixel, enabling smooth display lines by selectively activating only those sub-pixels whose emission regions intersect with the desired display line, thereby eliminating the serrated effect while maintaining manufacturing feasibility.
Solution Approach 2:
The patent introduces asymmetric radial arrangements of peripheral sub-pixels around the central sub-pixel, with sub-pixels positioned at different angular orientations and distances. This asymmetric configuration allows optimized control over display line smoothness in different directions, enabling the display to render smooth lines at various angles without requiring symmetric complexity that would complicate manufacturing.
2Manufacturing precision
If peripheral sub-pixels are added around each central sub-pixel to reduce serrated display, then display quality improves, but device complexity increases
Solution Approach 1:
The patent merges multiple sub-pixels (central and peripheral) into a single functional pixel unit that operates together to produce smooth display lines. By combining these sub-pixels with the same or complementary light-emitting colors within a shared control region, the system achieves smooth display quality while managing complexity through unified control mechanisms and shared structural elements like common electrodes and encapsulation layers.
Solution Approach 2:
The patent implements dynamic control of peripheral sub-pixels based on the position and orientation of display lines. The control mechanism dynamically determines which peripheral sub-pixels to activate or deactivate depending on the desired display line direction, allowing the pixel structure to adapt its effective configuration in real-time. This dynamic approach reduces the need for static structural complexity while maintaining high display quality across various line orientations.
