Foldable Display Curvature Adjustment for Viewing Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large peripheral displays suffer from decreased visual image quality as the viewing angle increases, especially when the user moves closer, due to the inherent limitations of LCD and OLED technologies, which cannot maintain optimal image quality across the entire display area.
Innovation Solution
An information handling system with a foldable display panel and an actuator that incrementally adjusts the curvature radius based on the user's viewing context, including distance, application type, and personal preferences, to optimize visual image presentation.

Engineering Contradiction Analysis
1Area of stationary object
If the display surface area is increased to provide a larger viewing area, then the viewing area is improved, but the visual image quality deteriorates due to increased viewing angles
Solution Approach 1:
The display panel is curved instead of flat, which changes the geometry of the viewing surface. This curvature allows users to view content from closer distances without experiencing excessive viewing angles that degrade image quality. The curved surface distributes the viewing angles more evenly across the display area.
Solution Approach 2:
The display curvature is made adjustable through an actuator mechanism that can change the curve radius dynamically. The system can transition between different curvature states (e.g., flat, partially curved, fully curved) based on user preferences, viewing distance, or content type, allowing optimization of image quality for different scenarios.
2Manufacturing precision
If the display is curved to improve viewing quality, then the visual image quality is improved, but the device complexity increases due to additional actuators and control mechanisms
Solution Approach 1:
The system automatically adjusts the display curvature based on sensors that detect user position, viewing distance, or environmental conditions. The curvature adjustment is performed autonomously without requiring manual user input, reducing the need for complex user interface mechanisms while maintaining optimal image quality.
Solution Approach 2:
The actuator changes the physical parameter of the display panel's curvature radius to optimize image quality. By dynamically adjusting this geometric parameter based on detected viewing conditions, the system maintains high visual quality without requiring multiple fixed-curvature display panels, thus reducing overall device complexity.
3Device complexity
If the curvature radius is fixed to simplify the display structure, then the device complexity is reduced, but the adaptability to different viewing contexts is limited
Solution Approach 1:
The display curvature transitions from a fixed static parameter to a dynamic adjustable parameter. The actuator enables the curvature radius to change in response to different viewing contexts such as user distance, preferred viewing angle, or content characteristics, providing adaptability while using a single mechanical system rather than multiple fixed configurations.
Solution Approach 2:
A single adjustable curvature mechanism serves multiple functions: it can optimize viewing for close-up content, provide a balanced curvature for typical use, and achieve a flat configuration for certain applications. This multi-functional actuator system replaces what would otherwise require multiple specialized display panels, maintaining simplicity while enhancing adaptability.

AI summary
An information handling system display has a foldable display panel that incrementally transitions between a flat and fully curved configuration with an amount of curve set based on one or more of plural conditions, such as a distance to a view, an application selected to present visual information, a location and size of visual information presented in a window or other partial area of the display panel, a type of input device or other factors. An end user may configure the display to adjust display panel curve radius as desired by personal preference, and the display panel tracks manual curvature selections by an end user to adapt automatically to the end user's preferences.
