Display Substrate Pixel Group Arrangement for High Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional display apparatuses face challenges in increasing resolution due to the complexity and cost of manufacturing, as the number of sub-pixels needed increases, making it difficult to meet high resolution requirements with the traditional RG/BG pixel arrangement.
Innovation Solution
A display substrate with pixel groups comprising two first sub-pixels, eight second sub-pixels, and two third sub-pixels, where each first sub-pixel corresponds to two second sub-pixels and each third sub-pixel corresponds to two second sub-pixels, reducing the number of first and third sub-pixels and simplifying the manufacturing process while maintaining high resolution.

Engineering Contradiction Analysis
1Measurement precision
If the number of sub-pixels is increased to improve resolution, then the resolution of the display apparatus is improved, but the complexity of manufacturing process and manufacturing cost are increased
Solution Approach 1:
The patent applies multi-functionality by making the first and third sub-pixels serve multiple purposes. Each first sub-pixel corresponds to and works with multiple second sub-pixels (e.g., first sub-pixel R1 corresponds to second sub-pixels G1, G2, G3, G4), allowing a reduced number of first and third sub-pixels to maintain high resolution display capabilities through shared functionality across multiple pixel locations.
Solution Approach 2:
The patent merges the functionality of multiple sub-pixel types into a coordinated system where first, second, and third sub-pixels work together in pixel groups. The merging of red, green, and blue sub-pixels in specific arrangements (with first sub-pixels sharing correspondence across multiple second sub-pixels) creates an integrated pixel structure that achieves high resolution without requiring a proportional increase in total sub-pixel count.
2Measurement precision
If the number of sub-pixels is increased to improve resolution, then the resolution of the display apparatus is improved, but the manufacturing cost is increased
Solution Approach 1:
The patent reduces manufacturing cost by making sub-pixels universal across multiple positions. The first sub-pixels (R1, R2) and third sub-pixels (B1, B2) serve multiple corresponding second sub-pixels, meaning fewer total sub-pixels are needed to achieve the same resolution, directly reducing material consumption and manufacturing cost.
Solution Approach 2:
The patent changes the organizational parameters of sub-pixel arrangement from traditional RGB patterns to a reconfigured system with pixel groups containing specific ratios of first, second, and third sub-pixels. This parameter change in sub-pixel distribution and correspondence relationships allows maintaining resolution while reducing the total quantity of sub-pixels required.
3Measurement precision
If traditional RG/BG pixel arrangement is used to achieve high resolution, then resolution can be improved, but it becomes difficult to meet larger resolution requirements due to manufacturing complexity
Solution Approach 1:
The patent segments the display into repeating pixel groups, each containing a specific configuration of first, second, and third sub-pixels. This segmentation into modular units with standardized internal structures (where first sub-pixels correspond to multiple second sub-pixels in a defined pattern) simplifies manufacturing by allowing repetitive production of identical pixel group modules.
Solution Approach 2:
The patent improves ease of manufacture by creating universal first and third sub-pixels that can correspond to multiple second sub-pixels across different positions. This universality means the same first sub-pixel design can be used in multiple locations within pixel groups, standardizing the manufacturing process and reducing complexity compared to traditional arrangements where each sub-pixel position requires unique configuration.
