Display Edge Emphasis with Color Blending to Limit Burn-In
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for visually impaired individuals face issues with burn-in phenomena due to excessive pixel stress during edge enhancement, leading to pixel deterioration and color deviation.
Innovation Solution
An electronic apparatus processes images to enhance edges with a preset thickness using a blend of colors, adjusting weight values based on local contrast and pixel movement, reducing pixel stress and minimizing burn-in by using specific color combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If edge enhancement is applied to assist visually impaired users, then edge visibility is improved, but pixel stress increases causing burn-in phenomenon
Solution Approach 1:
The patent applies different color treatments to different regions within the edge enhancement area. Specifically, it distinguishes between a first area (one direction from the edge) and a second area (opposite direction), applying different colors or color intensities to each. This local differentiation reduces overall pixel stress while maintaining edge visibility for visually impaired users.
Solution Approach 2:
The patent changes color parameters (hue, saturation, or intensity) in the edge enhancement area to reduce pixel stress. By adjusting color properties rather than simply increasing brightness or contrast uniformly, the system maintains edge visibility while preventing burn-in phenomenon caused by excessive pixel stress.
2Measurement precision
If edge area is expanded to preset thickness, then edge detection is improved, but color uniformity deteriorates due to burn-in
Solution Approach 1:
The patent divides the expanded edge enhancement area into distinct regions (first area and second area) and applies different color treatments to each. This local quality approach maintains color consistency within each sub-region while preventing uniform color degradation across the entire edge area, thereby preserving both edge detection accuracy and color stability.
