Variable-Curvature Display Control for User Proximity Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices, particularly OLEDs, face challenges in adapting their user interface output based on curvature changes, as they lack a mechanism to dynamically adjust the display's shape in response to user proximity or content arrangement, limiting immersive viewing experiences.
Innovation Solution
A display device with a bending module and controller that allows the display to switch between flat, first bending, and second bending modes based on distance to a remote controller, number of controllers, or content arrangement, enabling automatic or user-controlled curvature changes with a user interface indicating mode switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display module is fixed in a curved shape, then the immersive viewing experience is improved, but the adaptability to different viewing scenarios and user proximity is reduced
Solution Approach 1:
The display module transitions from a static curved shape to a dynamic structure that can change curvature. The bending module enables the display to switch between flat mode and different bending modes (first bending mode with smaller curvature, second bending mode with larger curvature), allowing adaptation to various viewing scenarios and user distances.
Solution Approach 2:
The curvature parameter of the display module is made variable through the bending module. By changing the curvature parameter between different predetermined values (flat, first bending, second bending), the system adapts to different viewing conditions while maintaining manufacturing simplicity.
2Adaptability or versatility
If the display module switches curvature based on remote controller distance, then the user interface adaptability is improved, but the device complexity increases
Solution Approach 1:
The controller receives feedback about the distance to the remote controller and automatically adjusts the display curvature accordingly. This feedback mechanism enables automatic adaptation to user proximity without requiring manual intervention, improving user interface adaptability while managing complexity through automated control.
Solution Approach 2:
The display system performs self-adjustment of curvature based on detected remote controller distance, eliminating the need for manual user input for each curvature change. The system serves itself by automatically selecting the appropriate bending mode based on real-time distance measurements.
3Ease of operation
If the display module supports multiple bending modes, then the viewing angle optimization is improved, but the control complexity increases
Solution Approach 1:
The display module incorporates multiple predetermined bending modes (first bending mode with smaller curvature, second bending mode with larger curvature) that can be dynamically selected based on viewing conditions. This dynamic capability allows optimization of viewing angles for different scenarios while keeping the control system manageable through predefined modes.

AI summary
A display device includes a main body provided with a display module on which an image is displayed, a bending module located at a center of a rear surface of the main body, and a controller. The controller includes controlling the bending module to change a curvature of the display module to any one of a flat mode in which the display module is flat, a first bending mode in which the display module has a first curvature, and a second bending mode in which the display module has a second curvature. Here, the second curvature is a maximum curvature of the display module. The controller further includes switching the display module to any one of the flat mode, the first bending mode, and the second bending mode based on a distance to a remote controller.
