OLED Sub-Pixel Octagon Layout for Higher Pixel Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current OLED display panels suffer from low pixel density and poor resolution due to their pixel arrangement, which limits their display quality.
Innovation Solution
The display panel is designed with multiple sub-pixels of different colors arranged in a virtual octagon structure, where each pixel unit includes one first sub-pixel, one second sub-pixel, and two third sub-pixels, allowing for close packing and increased pixel density and resolution through a specific geometric arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pixels are arranged in a real RGB mode with independent sub-pixels according to a certain distribution law, then the device complexity is reduced and ease of manufacture is improved, but the pixel density is low and the resolution is poor
Solution Approach 1:
The pixel is segmented into multiple sub-pixels (first sub-pixel, second sub-pixel, and third sub-pixels) with different colors and functions. Each sub-pixel is independently controlled and emits different colors, allowing the pixel to display a wider color gamut while increasing pixel density. The segmentation of pixel functions into multiple specialized sub-pixels resolves the contradiction between manufacturing simplicity and display quality.
Solution Approach 2:
The patent introduces a new spatial arrangement dimension by positioning sub-pixels at specific coordinates forming a virtual octagon structure. The third sub-pixels are arranged on opposite sides of the pixel column, creating a multi-dimensional layout that increases pixel density without simply reducing pixel pitch in one direction. This dimensional approach allows higher resolution while maintaining manageable device complexity.
2Manufacturing precision
If more sub-pixels are arranged in each pixel unit to increase pixel density, then the resolution is improved, but the area occupied by each sub-pixel is reduced
Solution Approach 1:
Multiple sub-pixels (first sub-pixel, second sub-pixel, and third sub-pixels) are merged within a single pixel unit to form a collaborative display element. The third sub-pixels are positioned on opposite sides and work together with the first and second sub-pixels to enhance the overall pixel density and resolution. This merging approach allows resolution improvement while maintaining adequate sub-pixel areas through efficient spatial utilization.
Solution Approach 2:
The patent utilizes spatial dimensionality by arranging sub-pixels in a virtual octagon configuration with specific coordinate relationships. The third sub-pixels are positioned on opposite sides of the pixel column, creating a multi-dimensional arrangement that maximizes the use of available space. This dimensional approach enables higher resolution without proportionally reducing sub-pixel areas, as the layout efficiently packs sub-pixels in multiple spatial directions.

AI summary
A display panel includes first sub-pixels, second sub-pixels and third sub-pixels. Each pixel unit includes a first sub-pixel, a second sub-pixel and two third sub-pixels disposed in a virtual octagon. The two third sub-pixels are distributed on two opposite sides of a pixel column constituted by the first sub-pixel and the second sub-pixel.
