Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If IPS LCD screen technology is used to improve viewing angle and color reproduction, then color reproduction and viewing angle are improved, but brightness and color shift still occur when viewed off-angle
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting color point control data based on viewing angle. The system modifies color and brightness parameters in real-time according to the detected viewing angle, transforming the static display characteristics into dynamic ones that adapt to different observation conditions, thereby resolving the contradiction between improved color reproduction and brightness consistency.
Solution Approach 2:
The patent implements feedback mechanisms by detecting the user's viewing angle and using this information to adjust display parameters. The system continuously monitors the viewing angle and feeds this information back to the color management system, which then compensates for brightness and color shifts, maintaining consistent visual performance across different viewing positions.
2Manufacturing precision
If display design is optimized for center viewing position, then visual performance at center is improved, but color and brightness shifts occur at off-angle positions
Solution Approach 1:
The patent transforms the static display optimization into a dynamic system that adapts to different viewing angles. By implementing real-time adjustments based on detected user position, the system maintains high visual performance whether the user is viewing from the center or off-angle positions, thereby achieving both manufacturing precision and viewing angle adaptability.
Solution Approach 2:
The patent applies local quality by implementing viewing-angle-specific color point control data. Different regions of the display (corresponding to different viewing angles) are optimized with tailored compensation parameters, allowing each local area to maintain optimal visual characteristics for its specific viewing position.
3Adaptability or versatility
If color management compensation is implemented to maintain consistent visual performance, then viewing angle adaptability is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing color point control data for various viewing angles. Instead of performing complex real-time calculations, the system uses pre-computed compensation data that is selected based on the detected viewing angle, thereby achieving viewing angle adaptability while minimizing the computational complexity of the color management system.

AI summary
An information handling system (IHS) controls a display for an immersive experience based upon a gazing view of one or more users. A processor communicates with the display and a gaze detector to detect a relative location of the user(s) to the display. A graphic processing unit (GPU) allocates a field of view on the display based upon the relative location, centers display content in the field of view on the display, and accesses color point control data in response to the allocated field of view. The GPU manages color and brightness of display components of the display according to the accessed color point control data to compensate for variations of color and brightness in a viewing angle of the field of view.
