Multi-Display VR Lighting Adaptation for Viewing Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In four-sided display assemblies for mixed reality, users experience varying brightness and contrast across displays due to different viewing angles, leading to an unrealistic 3D scene perception.
Innovation Solution
An apparatus with a processor assembly that determines viewing angles for each display in a multi-display assembly and adjusts brightness and contrast accordingly to optimize the viewing experience.

Engineering Contradiction Analysis
1Ease of operation
If brightness and contrast are adjusted uniformly across all displays, then device complexity is reduced, but viewing quality deteriorates due to angle-dependent display characteristics
Solution Approach 1:
The patent applies local quality by adjusting brightness and contrast parameters individually for each display based on its specific viewing angle characteristics. Each display receives customized brightness/contrast settings tailored to its orientation, compensating for angle-dependent variations in display performance and achieving uniform perceived quality across all displays.
Solution Approach 2:
The system dynamically adjusts brightness and contrast parameters based on real-time viewing angle measurements. The processor continuously monitors viewing angles and modifies display parameters accordingly, transforming static uniform settings into adaptive dynamic control that responds to changing viewing conditions.
2Ease of operation
If brightness and contrast are adjusted individually for each display based on viewing angle, then viewing quality is improved, but device complexity increases
Solution Approach 1:
The system implements self-service by automatically measuring viewing angles and computing appropriate brightness/contrast adjustments without user intervention. The processor autonomously monitors display orientation, determines optimal parameters, and applies corrections, eliminating the need for manual calibration while maintaining high viewing quality.
Solution Approach 2:
The patent employs feedback mechanisms where the processor continuously monitors viewing angle data and uses this information to adjust brightness and contrast settings. This closed-loop control ensures that displays adapt to changing viewing conditions, maintaining optimal quality through real-time parameter optimization based on measured angular characteristics.
