Display Substrate Alternating Pixel Units for Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display technologies face challenges in increasing human visual resolution due to complex manufacturing processes and high defective rates when trying to enhance pixel density, particularly with RGB or RGBW designs.
Innovation Solution
A display substrate and driving method that alternately arrange first and second pixel units, each composed of three sub-pixels, where the first pixel unit includes one sub-pixel and the second pixel unit includes two sub-pixels, arranged in a 2×3 matrix pattern, with luminance values calculated by summing adjacent sub-pixels' values to simplify manufacturing and reduce defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional RGB or RGBW pixel designs are used to increase human visual resolution, then pixel density needs to be increased, but manufacturing process complexity increases and defective rate increases
Solution Approach 1:
The pixel unit is segmented into three separate sub-pixels (first sub-pixel, second sub-pixel, third sub-pixel) that can be independently controlled and addressed. Each sub-pixel is driven separately through shared control lines, allowing the system to achieve higher effective resolution without proportionally increasing the number of physical pixel units manufactured.
2Measurement precision
If pixel density is increased to meet user requirements, then visual resolution improves, but manufacturing defective rate increases
Solution Approach 1:
Multiple sub-pixels share common control lines (first control line, second control line, third control line) and are grouped into pixel units with shared emission control. This merging reduces the total number of independent manufacturing structures required, thereby lowering the probability of manufacturing defects while maintaining high visual resolution through independent sub-pixel control.
3Measurement precision
If more sub-pixels are combined into pixel units to increase resolution, then visual quality improves, but manufacturing process becomes more complicated
Solution Approach 1:
The control lines and pixel unit structures serve multiple functions: they control multiple different colored sub-pixels (red, green, blue) through the same physical infrastructure. The first control line controls the first sub-pixel across multiple pixel units, the second control line controls the second sub-pixel, and the third control line controls the third sub-pixel, creating a universal control system that simplifies manufacturing while enabling high-resolution color display.
