Dynamic Display Curvature Control via Movable Support Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices have fixed surface curvature, limiting the viewing experience for viewers at different positions, as they must be at a specific distance to achieve a desired viewing experience, which restricts flexibility and comfort.
Innovation Solution
A display apparatus that dynamically controls the surface curvature of a display screen through motion of support portions based on user input, allowing adaptation of the curvature to the viewer's field of view, enabling on-demand surface curvature control for immersive experiences across various applications and environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the surface curvature of the display screen is fixed at manufacturing time, then the manufacturing process is simple and cost-effective, but the viewing experience is limited for users at different positions
Solution Approach 1:
The display screen transitions from a fixed curvature structure to a dynamic adjustable curvature structure. The support portions can move relative to the display screen, enabling the surface curvature to be changed after manufacturing. This allows the system to adapt to different viewing positions and user preferences, resolving the contradiction between manufacturing simplicity and viewing adaptability.
Solution Approach 2:
The support structure is divided into multiple movable support portions rather than a single fixed support. Each support portion can independently adjust its position, allowing precise control over the display screen's curvature. This segmentation enables flexible curvature adjustment while maintaining a relatively simple overall structure.
2Ease of operation
If the display screen has a fixed surface curvature, then the device structure is simple, but users must be at a specific distance to achieve desired viewing experience
Solution Approach 1:
The support portions are designed to be movable rather than fixed, enabling the display screen curvature to be adjusted dynamically. Users can change the curvature to match their viewing distance and position, providing ease of operation without requiring users to maintain a specific distance from the screen.
Solution Approach 2:
The system allows changing the curvature parameter of the display screen based on user needs. By adjusting the position of support portions, the curvature parameter can be varied to optimize viewing experience for different distances and positions, enhancing operational flexibility.
3Adaptability or versatility
If the surface curvature is fixed for a single optimal viewing position, then the manufacturing precision requirement is low, but multiple users at different positions cannot achieve optimal viewing experience
Solution Approach 1:
Instead of manufacturing the display screen with a fixed curvature optimized for one position, the system uses movable support portions that allow curvature adjustment after manufacturing. This dynamic approach enables multiple users at different positions to achieve optimal viewing experience without requiring extremely precise manufacturing for a single curvature value.
Solution Approach 2:
The display screen system is designed to serve multiple viewing positions and user configurations through adjustable curvature. The same physical display screen can be optimized for different users by changing its curvature, providing universal adaptability without requiring multiple precisely-manufactured screens for different purposes.

AI summary
A display apparatus that comprises a display screen and a set of support portions, is provided. The display apparatus receives a user input that corresponds to a configuration of the display screen and controls motion of the set of support portions based on the received user input. A change in a surface curvature of the display screen is based on the motion of the set of support portions.
