Multi-Display Luminance Control via Positional Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a user is using multiple display areas simultaneously and viewing one display area, the optimal luminance of another display area varies with the luminance of the one display area, requiring proper control to ensure comfortable viewing.
Innovation Solution
An image display system that includes a first display area, a second display area, and a luminance determination unit, which determines the luminance of the second display area based on the luminance of the first display area and their positional relationships with the user, to display the second display area at an optimal luminance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple display areas are used simultaneously with high luminance, then visibility and image quality are improved, but glare increases and user comfort deteriorates
Solution Approach 1:
The patent applies local quality by determining different luminance levels for different display areas based on their positional relationships with the user. The luminance determination unit calculates appropriate luminance for each display area individually, allowing the primary display area to have higher luminance for visibility while secondary display areas have reduced luminance to minimize glare, thus resolving the contradiction between visibility and glare.
Solution Approach 2:
The patent changes the luminance parameter dynamically based on positional relationships. The system calculates luminance values for multiple display areas by considering factors such as viewing distance, display area size, and angular position, then adjusts each display area's luminance accordingly. This parameter change approach allows optimization of both visibility and glare reduction simultaneously.
2Illumination intensity
If the luminance of one display area is increased for better visibility, then the optimal luminance of other display areas must be adjusted, increasing system complexity
Solution Approach 1:
The system applies self-service by automatically determining appropriate luminance values for multiple display areas without requiring manual intervention. The luminance determination unit autonomously calculates and adjusts luminance settings based on detected positional relationships, eliminating the need for complex manual configuration while maintaining optimal visibility and comfort across all display areas.
Solution Approach 2:
The system implements feedback by continuously monitoring positional relationships between the user and display areas, then using this information to dynamically adjust luminance settings. The luminance determination unit receives input about display area positions and sizes, calculates appropriate luminance values, and applies these settings automatically, creating a closed-loop control system that simplifies complexity through automation.
