Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses with flat panels often provide suboptimal viewing experiences for viewers not positioned directly in front, as they do not accommodate varying viewer positions effectively.
Innovation Solution
A display apparatus with a deformable display module that can be selectively changed between a flat state and a curved state, utilizing a driving device to deform the module based on user selection or content type, ensuring optimal image quality for different viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat display panel is used, then the device structure is simple and manufacturing is easy, but the viewing quality for viewers not positioned directly in front deteriorates
Solution Approach 1:
The display panel is designed to be dynamically deformable between flat and curved states. A driving device with actuators (motors, belts, pulleys) enables the panel to change its curvature based on viewing requirements, transforming a static structure into a dynamic one that adapts to different viewing scenarios while maintaining good image quality
Solution Approach 2:
The curvature radius of the display panel is changed as a variable parameter. By adjusting the curvature radius from infinity (flat state) to a finite value (curved state), the system optimizes viewing quality for different positions without compromising manufacturing feasibility through the use of flexible display materials and modular driving mechanisms
2Manufacturing precision
If a curved display panel is used, then the viewing quality for various positions is improved, but the device structure becomes complex
Solution Approach 1:
The driving device is segmented into multiple independent modules: actuators mounted on the rear frame, belts running along the rear surface, and pulleys positioned at specific locations. This modular segmentation allows the curvature control function to be distributed across multiple simple components rather than requiring a single complex mechanism, thereby improving viewing quality while managing structural complexity
Solution Approach 2:
The display panel is designed with a specific curvature radius that optimizes viewing quality for various positions. The curved geometry allows light to reach viewers at different angles more effectively, and this curvature is achieved through the coordinated action of the segmented driving device components rather than requiring an inherently complex curved panel structure
3Adaptability or versatility
If the display panel is made deformable, then adaptability to different viewing positions is improved, but the reliability of the display module deteriorates
Solution Approach 1:
The system incorporates a controller that receives input signals (manual user input or automatic content-based determination) and controls the actuators to adjust the display panel curvature accordingly. This feedback control mechanism ensures the display module transitions reliably between flat and curved states while maintaining stability in each state, thereby improving adaptability without compromising reliability
Solution Approach 2:
The deformable display module serves multiple functions: it can maintain a flat state for standard viewing, transition to a curved state for enhanced viewing quality at various positions, and return to the flat state when needed. This multi-functionality is achieved through the reversible deformation capability enabled by the driving device, allowing the same display module to adapt to different viewing scenarios while maintaining reliability through controlled state transitions
