Splicing Screen Pixel Adjustment for Gap Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal display (LCD) splicing screens are limited by a splicing gap, which hinders their entry into high-end markets due to visual differences caused by varying pixel sizes, affecting display performance and competitiveness.
Innovation Solution
A method that adjusts pixel values and display areas between adjacent screens based on preset configuration parameters, calculating pixel ratios and adjusting edge area pixel sizes to minimize visual differences, allowing for seamless integration and improved display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LCD splicing screens are used to reduce cost, then price advantage is improved, but splicing gap and visual difference worsen
Solution Approach 1:
The patent applies local quality by adjusting pixel values specifically in the edge area of display screens where splicing gaps occur, rather than uniformly across the entire screen. The processing device identifies edge regions and applies targeted pixel value adjustments to these specific locations, making the edge area have different pixel characteristics from the center area, thereby reducing visible splicing gaps while maintaining overall display quality.
Solution Approach 2:
The patent changes pixel values as a key parameter to eliminate splicing gaps. By adjusting the pixel values in the edge area based on the pixel values of adjacent screens, the display characteristics are modified to create a seamless transition across spliced screens. This parameter change approach allows LCD screens to achieve visual effects comparable to higher-end LED screens without sacrificing cost advantages.
2Device complexity
If pixel values of adjacent screens are different, then device complexity is reduced, but visual difference at splicing gap worsens
Solution Approach 1:
The patent implements feedback by using the pixel values of one screen as reference to adjust the pixel values of adjacent screens. The processing device continuously monitors and compares pixel values across screen boundaries and applies corrective adjustments to ensure consistency. This feedback mechanism maintains display uniformity while accommodating different initial pixel configurations.
Solution Approach 2:
The patent applies preliminary action by pre-adjusting pixel values in the edge areas before final display output. The processing device proactively modifies pixel configurations in regions that will be adjacent to other screens, ensuring that when screens are spliced together, the pixel transitions are smooth and visually consistent. This preliminary adjustment prevents visual discrepancies from occurring in the first place.
