Display Panel Driver Color Weakness Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices struggle to simultaneously provide image displays for individuals with color vision impairment and normally sighted individuals, as existing technologies do not effectively compensate for color weakness in real-time without compromising image quality or requiring complex adjustments.
Innovation Solution
A display device with a display panel driver that performs color weakness-compensating conversion using a daltonization matrix for specific areas, allowing for simultaneous image display tailored to both groups by converting red, green, and blue signals based on predefined equations and logic values for pixel selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If color weakness-compensating conversion is performed for the entire display panel, then image display for color vision impaired individuals is improved, but image quality for normally sighted individuals deteriorates
Solution Approach 1:
The display panel is divided into a first area and a second area. The first area applies color weakness-compensating conversion for color vision impaired individuals, while the second area maintains original image quality for normally sighted individuals. This segmentation allows simultaneous optimization for different user groups without compromising either experience.
Solution Approach 2:
Different image processing qualities are applied to different regions of the display panel. The first area receives color weakness-compensating conversion with enhanced color differentiation, while the second area preserves the original high-quality image rendering. This local quality approach ensures each region serves its intended purpose optimally.
2Manufacturing precision
If color weakness-compensating conversion is not performed, then image quality is maintained, but accessibility for color vision impaired individuals deteriorates
Solution Approach 1:
The display panel is segmented into functional areas: the first area implements color weakness-compensating conversion to ensure accessibility for color vision impaired users, while the second area maintains standard image quality. This segmentation resolves the contradiction by providing targeted assistance only where needed.
Solution Approach 2:
Color weakness compensation is applied locally to the first area rather than globally across the entire display. This local quality adjustment maintains overall image quality while providing necessary accessibility support in specific regions.
3Adaptability or versatility
If complex adjustments are implemented for color weakness compensation, then accessibility is improved, but device complexity increases
Solution Approach 1:
The timing controller is segmented into multiple conversion units, each handling specific conversion tasks. The first conversion unit processes color weakness-compensating conversion for the first area, while the second conversion unit handles size conversion for the second area. This modular segmentation reduces overall system complexity by distributing conversion functions across specialized units.
Solution Approach 2:
The timing controller dynamically selects which conversion process to apply based on the target area. For the first area, color weakness-compensating conversion is applied; for the second area, size conversion or no conversion is applied. This dynamic approach allows flexible adaptation without requiring complex manual adjustments.
4Adaptability or versatility
If image signals are converted for both color and size, then versatility is improved, but processing complexity increases
Solution Approach 1:
The timing controller is divided into a first conversion unit for color weakness-compensating conversion and a second conversion unit for size conversion. Each unit handles a specific type of conversion independently, reducing the complexity of managing multiple conversion types within a single unit. This segmentation allows versatile processing while maintaining manageable system complexity.
Solution Approach 2:
The timing controller dynamically determines which conversion process to apply based on the display area and user needs. The first conversion unit processes color adjustments for the first area, while the second conversion unit handles size adjustments for the second area. This dynamic selection mechanism provides versatile processing capabilities without requiring all conversions to be active simultaneously, thus managing processing complexity.
