Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panel technologies face challenges in increasing resolution while maintaining a high aperture ratio and reducing manufacturing complexity, particularly in high-resolution OLED displays, where the size of sub-pixels becomes excessively small, leading to difficulties in manufacturing and potential color mixing.
Innovation Solution
A display panel arrangement where sub-pixels are arranged in a 2×2 matrix with each pixel unit corresponding to a respective sub-pixel, allowing for one-to-one correspondence and using pixel rendering technology to combine adjacent sub-pixels' brightness, thereby reducing manufacturing complexity and maintaining a high aperture ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of sub-pixels in a same area is increased to improve resolution, then the resolution is improved, but the size of each sub-pixel becomes excessively small leading to increased manufacturing difficulty and risk of color mixing
Solution Approach 1:
The invention divides a logical pixel into multiple physical sub-pixels (e.g., one red sub-pixel, two green sub-pixels, one blue sub-pixel) that work together to form a complete pixel. This segmentation allows the pixel to achieve high resolution while maintaining a reasonable physical size for each sub-pixel, thereby reducing manufacturing difficulty and the risk of color mixing.
2Measurement precision
If the number of sub-pixels in a same area is increased to improve resolution, then the resolution is improved, but the aperture ratio decreases due to the smaller sub-pixel size
Solution Approach 1:
By segmenting the pixel into multiple sub-pixels with different color weights (e.g., 1R-2G-1B), the invention achieves high resolution without requiring each sub-pixel to be extremely small. This allows for a larger effective aperture area while maintaining the required resolution level.
Solution Approach 2:
The invention changes the parameter distribution of sub-pixels within a pixel by using different quantities of sub-pixels for different colors (e.g., two green sub-pixels instead of one). This parameter change optimizes the aperture ratio while maintaining color accuracy and resolution.
3Measurement precision
If the sub-pixel size is decreased to improve resolution, then the resolution is improved, but the manufacturing precision requirements increase due to process limitations
Solution Approach 1:
The invention segments each pixel into multiple sub-pixels, which allows the overall pixel to achieve high resolution while each individual sub-pixel maintains a larger, more manufacturable size. This reduces the precision requirements for sub-pixel fabrication and positioning processes.
4Measurement precision
If the sub-pixel size is decreased to improve resolution, then the resolution is improved, but the aperture ratio becomes excessively small
Solution Approach 1:
By dividing the pixel into multiple sub-pixels (e.g., 1R-2G-1B configuration), the invention achieves high resolution without requiring each sub-pixel to be extremely small. This segmentation strategy maintains a larger effective aperture area while achieving the desired resolution level.
Solution Approach 2:
The invention merges multiple sub-pixels of the same color (e.g., two green sub-pixels) within a single pixel to increase the effective light-emitting area and aperture ratio, while still achieving high resolution through the overall pixel arrangement.
