Display Apparatus Background Image Consistency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display apparatuses, when images with different image sizes and resolutions are compared, the background color appears inconsistent due to variations in luminescence intensity, affecting the comparison of effective image regions.
Innovation Solution
A display apparatus with a processor or circuit that controls the display device to adjust luminescence intensity, color gamut, and electro optical transfer function (EOTF) for each image, ensuring the background appears visually identical across multiple images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the background color is uniformly set to the same value, then the background color has the same appearance, but the appearance of the background color may vary due to differences in the luminescence intensity of the backlight
Solution Approach 1:
The patent adjusts the background color parameters (luminance, color gamut, EOTF) according to the backlight luminescence intensity of each split region. By changing these parameters dynamically based on the actual backlight conditions, the background color appearance is maintained as consistent across different regions despite variations in luminescence intensity.
Solution Approach 2:
The patent applies different background color settings to different split regions based on their specific backlight luminescence intensity characteristics. Each region's background color is locally optimized to achieve visual consistency, rather than applying a uniform setting across all regions.
2Adaptability or versatility
If multiple images are displayed simultaneously on the display apparatus, then image comparison is enabled, but the background color appears inconsistent across images due to different luminescence intensity
Solution Approach 1:
When multiple images are displayed in split mode, the patent adjusts the background color parameters for each image according to the backlight luminescence intensity of its corresponding split region. This ensures that backgrounds across different images maintain visual consistency despite regional variations in luminescence.
Solution Approach 2:
The patent divides the display into multiple split regions, each with its own background color optimization. By segmenting the background color control by split region rather than applying a global setting, the system achieves consistent appearance across all displayed images while supporting multi-image comparison functionality.
