Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image display apparatuses struggle to adaptively control tiled displays to match varying screen aspect ratios of input images, leading to suboptimal viewing experiences due to fixed display configurations.
Innovation Solution
An image display apparatus comprising a controller that detects the screen aspect ratio of an input image and determines rotation control information, including rotating direction and angle, to adjust and control multiple rotatable display modules, ensuring optimal image presentation by maintaining the desired aspect ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the tiled display uses a fixed display configuration, then the device complexity is reduced, but the adaptability to different screen aspect ratios deteriorates
Solution Approach 1:
The display modules are configured to be rotatable rather than fixed, allowing the display system to dynamically adjust its orientation and aspect ratio configuration based on the input image properties. This enables the same physical hardware to adapt to different screen aspect ratios (e.g., 16:9, 21:9) by rotating modules to appropriate angles, resolving the contradiction between fixed configuration simplicity and adaptive versatility.
Solution Approach 2:
The system changes the rotational angle parameter of the display modules to match different screen aspect ratios. By adjusting the rotation angle of individual modules based on the detected aspect ratio of the input image, the system achieves adaptability without requiring completely different physical display configurations for each aspect ratio type.
2Adaptability or versatility
If the tiled display rotates to match different aspect ratios, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The system incorporates a detection mechanism that senses the aspect ratio of the input image and provides feedback to the control unit. Based on this feedback, the control unit automatically determines the appropriate rotation angle for each display module, enabling automatic adaptation to different aspect ratios without manual intervention and reducing the operational complexity despite the physical rotation mechanism.
Solution Approach 2:
The display system performs self-adjustment by automatically detecting the input image's aspect ratio and autonomously determining the rotation configuration needed. The control unit processes the aspect ratio information and independently calculates the rotation angles, allowing the system to service itself without external control, thereby managing the complexity through automation.
3Adaptability or versatility
If the display modules are made rotatable, then the adaptability to various screen formats improves, but the manufacturing complexity increases
Solution Approach 1:
The display system is divided into multiple independent rotatable modules rather than a single fixed display unit. Each module can be independently rotated and controlled, allowing the system to achieve various screen formats by combining different module orientations. This segmentation approach, while increasing assembly complexity, enables flexible configuration for different aspect ratios using standardized rotational mechanisms.
