Solution Overview

Problem

Display devices such as televisions often have a narrow preferred viewing angle, leading to degraded contrast, color, and brightness when viewed from angles outside this range, which is problematic in multi-user environments where users may be positioned at various angles relative to the device.

Innovation Solution

Systems and methods that utilize sensors to determine the viewing angle of users in real-time, adjusting display settings such as brightness, contrast, color, and saturation to compensate for the viewing angle, ensuring optimal image quality for multiple users by processing image settings before display or adjusting display device parameters dynamically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the display device uses a narrow preferred viewing angle design, then the image quality (contrast, color, brightness) is improved at the preferred angle, but the viewing experience deteriorates when users view from different angles

Engineering Contradiction:
Improveimage qualityVSAvoidviewing angle range
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the display settings adjustable and changeable based on viewing conditions. The system dynamically modifies brightness, contrast, color, and saturation parameters in response to detected viewing angles, transforming a static display into an adaptive one that maintains image quality across multiple viewing positions

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent directly implements parameter changes by modifying display parameters (brightness, contrast, color, saturation) based on the detected viewing angle. When the viewing angle deviates from the preferred angle, the system adjusts these parameters to compensate for the degradation, thereby maintaining acceptable image quality across a wider range of viewing angles

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the display device adjusts settings for multiple viewing angles, then the adaptability to different users is improved, but the system complexity increases due to real-time sensing and dynamic adjustment requirements

Engineering Contradiction:
Improvemulti-user supportVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies self-service by enabling the display device to automatically detect user position and adjust settings without manual intervention. The sensor system continuously monitors viewing angles and the control system autonomously modifies display parameters, eliminating the need for users to manually configure settings for different viewing positions

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements feedback through a closed-loop system where sensors detect viewing angles, the control system processes this information, and adjusts display settings accordingly. This continuous feedback mechanism allows the system to adapt to changing viewing conditions in real-time, maintaining optimal image quality for multiple users

Inventive Principle:
Principle #23Feedback

AI summary

Various embodiments for compensating for user view angle of a display device are presented. The viewing angle of a user may be determined using sensors. Based on the viewing angle, the attenuation of the output of the display device may be determined. Compensation mode for the display output may be determined. The compensation mode may adjust the output of the display to compensate for the display attenuation allowing an improved image quality at large viewing angles.
