Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device scales images at predetermined sizes or intervals using conventional methods, then the device complexity is reduced and ease of operation is improved, but the manufacturing precision and measurement precision of image curvature representation deteriorate
Solution Approach 1:
The patent applies dynamics by transitioning from static predetermined scaling intervals to dynamic continuous scaling ratios. The controller calculates and applies different scaling ratios based on actual curvature requirements, allowing the system to adapt precisely to various curvature values rather than being constrained to fixed intervals. This enables accurate representation of images with any curvature while maintaining operational simplicity through automated calculation.
Solution Approach 2:
The patent changes the parameter of scaling from discrete predetermined values to continuous variable values. By introducing curvature-based scaling ratios that can take any value within a range, the system achieves precise control over image curvature representation. The controller adjusts scaling parameters dynamically based on the desired curvature, eliminating the precision limitations of fixed intervals.
2Adaptability or versatility
If the display device uses fixed scaling ratios for images with different curvatures, then the device complexity is minimized, but the adaptability and manufacturing precision for representing various curvatures deteriorate
Solution Approach 1:
The patent applies self-service by enabling the controller to automatically calculate and apply appropriate scaling ratios based on the input curvature value. The system serves itself by internally determining the correct scaling parameters without requiring external intervention or complex manual configuration. This automation increases adaptability to various curvatures while keeping the user interface simple.
Solution Approach 2:
The patent applies preliminary action by pre-establishing the relationship between curvature values and scaling ratios through mathematical formulas. The controller is programmed with the logic to compute scaling ratios before actual image display, allowing rapid adaptation to different curvatures without real-time complex processing. This preparatory computational framework reduces operational complexity while maintaining high adaptability.
3Shape
If the display device displays curved images on flat panels without curvature-based scaling, then the ease of manufacture and device complexity are reduced, but the shape accuracy and visual quality deteriorate due to distortion and discontinuity
Solution Approach 1:
The patent replaces mechanical curvature (physical curved panels) with computational curvature (software-based scaling). Instead of manufacturing physically curved display panels, the system uses image processing algorithms to create the visual effect of curvature on flat panels. This substitution maintains ease of manufacture while achieving accurate curvature representation through pixel scaling and positioning adjustments.
Solution Approach 2:
The patent addresses curvature representation by introducing a computational dimension through scaling ratio calculations. Rather than physically bending the panel in three-dimensional space, the system manipulates the two-dimensional image data to simulate curvature effects. This dimensional approach allows accurate curvature representation without compromising manufacturing simplicity.
4Manufacturing precision
If the display device applies uniform scaling to all pixels, then the ease of operation and device complexity are improved, but the manufacturing precision and visual quality for curved images deteriorate
Solution Approach 1:
The patent applies segmentation by dividing the image into individual pixels or pixel groups, each subjected to specific scaling ratios based on its position and the desired curvature. Rather than applying a single uniform scale to the entire image, the controller calculates and applies differentiated scaling to various segments, achieving precise curvature representation through localized adjustments while maintaining systematic control.

AI summary
A display device and a method of controlling the same. The display device includes a display configured to display an image; and a controller configured to perform image processing on the displayed such that a radius of curvature of the displayed image and a radius of curvature of a visible image are different. The image can be enlarged to a maximum area providing in the display device by applying analogous viewing distance calculation method used in the curved display device with respect to the scaling of the image. Accordingly, the discontinuity of the image can be removed by providing continuous scaling, and the perspective, presence, viewing experience can be enhanced while adaptively correcting the brightness. The display device can display the image having the curvature that the user wants, and thus resemble the curved display device. Further, optical illusion of watching the three-dimensional image can be generated.
