Display Viewing Angle Compensation via Real-Time Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices, such as LCDs, experience significant degradation in viewing quality, including brightness and contrast, when viewed from angles greater than 20 degrees, leading to a negative user experience, especially in configurations where secondary display/input devices are positioned adjacent to primary displays.
Innovation Solution
An information handling system with a viewing angle compensation engine that analyzes user positions and viewing angles relative to the display screen, applying modifications to the display output to maintain optimal brightness, contrast, and color across various viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the secondary display/input device is positioned adjacent to the primary display device with the screen oriented perpendicularly to the primary display screen, then the device configuration allows for additional input and viewing functionality, but the viewing angle degradation becomes significant in common-use situations
Solution Approach 1:
The system dynamically adjusts display parameters (brightness, contrast, color temperature) in real-time based on the detected viewing angle. The processing system continuously monitors user position and modifies display output characteristics to compensate for angle-related degradation, transforming the static display into an adaptive system that maintains optimal viewing quality regardless of orientation.
Solution Approach 2:
The patent changes physical display parameters (luminance, contrast ratio, color gamut) based on the viewing angle detected by the image capturing device. By adjusting these parameters dynamically, the system compensates for the natural degradation that occurs at oblique angles, effectively resolving the contradiction between versatile positioning and maintained display quality.
2Adaptability or versatility
If the secondary display/input device is positioned adjacent to the primary display device with the screen oriented perpendicularly to the primary display screen, then the device configuration allows for additional input and viewing functionality, but the viewing quality degradation occurs in common-use situations
Solution Approach 1:
The system implements a feedback loop where the image capturing device continuously detects user position and viewing angle, the processing system analyzes this data, and the display parameters are adjusted accordingly. This closed-loop control ensures that viewing quality remains consistent across different configurations and angles, resolving the contradiction between versatility and reliability.
3Adaptability or versatility
If LCD display characteristics are viewed at angles greater than 20 degrees from the perpendicular position, then the display can be viewed from wider angles, but brightness, contrast, and color degradation occur substantially
Solution Approach 1:
The system applies preliminary compensation by detecting the viewing angle in advance and adjusting display parameters before significant degradation occurs. By proactively modifying brightness, contrast, and color settings based on predicted viewing conditions, the system prevents quality loss rather than merely reacting to it.
4Adaptability or versatility
If LCD display characteristics are viewed at angles greater than 20 degrees from the perpendicular position, then the display can be viewed from wider angles, but contrast degradation occurs substantially
Solution Approach 1:
The system dynamically changes contrast ratio parameters based on detected viewing angle. By increasing contrast compensation at oblique angles and maintaining optimal contrast at perpendicular viewing, the system preserves image quality across the full viewing angle range, resolving the contradiction between viewing angle versatility and contrast reliability.

AI summary
A display device viewing angle compensation system includes a computing device that is coupled to a display device and an image capturing device. The computing device is configured to receive at least one image from the image capturing device, analyze the at least one image to detect a first user, and determine a first user viewing angle relative to the display screen. The computing device then determines at least one display screen output modification using the first user viewing angle. The computing device then applies the at least one display screen output modification to the display device to modify at least one display screen output provided on the display screen. The at least one display screen output modification may modify a display screen brightness output, a display screen contrast output and/or a display screen color output provided on the display screen.
