Gamma Correction for Non-Uniform Display Subareas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gamma correction methods are inadequate for display panels with non-uniform pixel density, as they cannot accurately adjust the display brightness of subareas with different resolutions, leading to poor image quality and visibility issues.
Innovation Solution
A gamma correction method that separately adjusts the display brightness of each subarea with different resolutions by using a reference brightness to determine correction parameters, allowing for improved granularity and accuracy in gamma correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform gamma correction is applied to the entire display panel, then the correction process is simple, but it cannot accurately correct subareas with different resolutions leading to poor image quality
Solution Approach 1:
The display panel is divided into multiple subareas with different resolutions (first subarea with first resolution, second subarea with second resolution). Each subarea is independently corrected using its own correction parameters, allowing accurate brightness adjustment for each resolution level while maintaining a systematic correction process.
Solution Approach 2:
Different correction parameters are applied to different subareas based on their specific resolution characteristics. The first subarea receives correction parameters optimized for its resolution, while the second subarea receives different correction parameters suited to its resolution, ensuring locally optimal image quality for each region.
2Manufacturing precision
If separate gamma correction is performed for each subarea with different resolutions, then image quality is improved, but the correction process becomes more complex
Solution Approach 1:
The gamma correction apparatus is designed to handle multiple subareas with different resolutions using a unified correction framework. The same apparatus can process the first subarea with first resolution and the second subarea with second resolution, applying different correction parameters through a single integrated system, thereby reducing overall complexity.
Solution Approach 2:
The system adjusts correction parameters dynamically based on the resolution of each subarea. By changing the correction parameters according to the specific resolution requirements of each subarea, the system achieves accurate correction without requiring fundamentally different correction mechanisms for each subarea.
3Adaptability or versatility
If the display panel has non-uniform pixel density with different resolution subareas, then display flexibility is improved, but uniform gamma correction methods fail to ensure ideal display brightness
Solution Approach 1:
The display panel is segmented into distinct subareas (first subarea, second subarea) with different resolutions and pixel densities. This segmentation allows each subarea to be independently characterized and corrected, ensuring that the varying pixel densities are properly compensated to achieve consistent display brightness across the entire panel.
Solution Approach 2:
Each subarea receives localized correction parameters tailored to its specific pixel density and resolution characteristics. This local quality approach ensures that the first subarea and second subarea, despite their different resolutions, both achieve ideal display brightness through region-specific optimization.
