Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panels with low pixel per inch (PPI) suffer from a granular sensation, making images appear serrated, and increasing PPI to improve resolution complicates the manufacturing process.
Innovation Solution
A pixel array with three sub-pixels in different colors per unit, where two adjacent sub-pixels are combined into a pixel block, and a driving method that calculates actual brightness values by summing theoretical values of adjacent sub-pixels to reduce granular sensation and enhance resolution without increasing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pixel per inch (PPI) is increased to improve resolution, then display quality is improved, but manufacturing complexity increases
Solution Approach 1:
Each pixel is segmented into multiple sub-pixels (red, green, blue) that can be independently controlled. By combining adjacent sub-pixels of the same color into pixel blocks and using brightness compensation algorithms, the system achieves higher effective resolution without proportionally increasing physical pixel density, thereby reducing manufacturing complexity while improving display quality
Solution Approach 2:
The patent uses virtual pixel blocks formed by combining multiple physical sub-pixels to create additional display elements. Through brightness compensation algorithms, the system creates virtual high-resolution images from lower physical resolution, effectively increasing display resolution without the manufacturing complexity of physically denser pixel arrangements
2Object-affected harmful factors
If pixel per inch (PPI) is increased to reduce granular sensation, then visual smoothness is improved, but manufacturing difficulty increases
Solution Approach 1:
Adjacent sub-pixels of the same color are merged into pixel blocks, where the brightness of individual sub-pixels is compensated based on the combined block brightness. This merging approach reduces the visible granularity by creating larger effective display elements while maintaining manufacturing feasibility through standard sub-pixel structures
Solution Approach 2:
The patent dynamically adjusts the brightness parameters of individual sub-pixels within pixel blocks through compensation algorithms. By changing brightness parameters rather than physical structures, the system reduces granular sensation without increasing manufacturing difficulty, as the same physical pixels are used with modified drive signals
