OLED Pixel Arrangement Sharing Sub-pixels to Reduce Manufacturing Difficulty
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional RGB pixel arrangements in OLED display panels require a high density of sub-pixels to achieve high resolution, leading to increased manufacturing difficulty and cost.
Innovation Solution
An alternative pixel arrangement where first and second sub-pixels are alternately arranged in rows and columns, with third sub-pixels inserted between them, allowing for sharing of sub-pixels between pixel units to achieve high resolution with a reduced number of sub-pixels.

Engineering Contradiction Analysis
1Measurement precision
If the density of sub-pixels is increased to achieve high resolution, then the resolution of the display panel is improved, but the manufacturing difficulty and cost increase
Solution Approach 1:
The patent applies multi-functionality by enabling sub-pixels to serve multiple purposes: each sub-pixel is shared by multiple pixel units (e.g., a first sub-pixel is shared by first and second pixel units, a third sub-pixel is shared by multiple pixel units). This allows the same physical sub-pixel to contribute to multiple pixel definitions, achieving high resolution without proportionally increasing the total number of sub-pixels, thereby reducing manufacturing complexity while maintaining high measurement precision (resolution).
Solution Approach 2:
The patent merges multiple pixel units by having them share common sub-pixels. Instead of providing dedicated sub-pixels for each pixel unit, the invention combines the resource requirements of multiple pixel units, allowing them to share first sub-pixels, second sub-pixels, and third sub-pixels. This merging approach reduces the total sub-pixel count needed while achieving the desired resolution level, thus easing manufacturing difficulty.
2Measurement precision
If the density of sub-pixels is increased to achieve high resolution, then the resolution of the display panel is improved, but the manufacturing cost increases
Solution Approach 1:
The patent reduces manufacturing cost by making sub-pixels universal across multiple pixel units. Each sub-pixel type (first, second, third sub-pixels) is designed to be shared by multiple pixel units, meaning the same physical component serves multiple functional roles. This universality reduces the total number of sub-pixels that need to be manufactured and assembled, directly lowering manufacturing costs while maintaining high resolution performance.
Solution Approach 2:
The patent recovers sub-pixel resources by having them shared across multiple pixel units. Instead of discarding or dedicating sub-pixels to single pixel units, the invention recovers and reuses them in multiple contexts. For example, first sub-pixels are recovered and shared by both first and second pixel units, and third sub-pixels are recovered and shared by multiple pixel units, thereby reducing the overall sub-pixel inventory needed and lowering manufacturing costs.

AI summary
Disclosed is a pixel arrangement of an OLED display panel and an OLED display panel. The pixel arrangement includes first sub-pixels and second sub-pixels that are arranged alternately along a row direction. Every other pair of first sub-pixel and second sub-pixel are provided therebetween with two third sub-pixels along the row direction. The first sub-pixels and the third sub-pixels are arranged alternately along a column direction to form a sub-pixel arrangement mode, and the second sub-pixels and the third sub-pixels are arranged alternately to form another sub-pixel arrangement mode. The two sub-pixel arrangement modes are arranged alternately. The pixel arrangement reduces difficulty in manufacturing an OLED display panel.
