Display Device with Bend Control Unit for Curved Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices, such as flat panel displays, often suffer from limited viewing angles and lack of stereoscopic effects, especially in larger screens, as they cannot easily transition between plane and bent states to enhance image quality and immersion.
Innovation Solution
A display device equipped with a bend control unit, comprising a Y-shaped member, elastic member, and movement unit, allows the display panel to be easily switched between plane and bent states by pressurizing specific regions, enabling controlled curvature and wider viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional flat panel display is used, then the device structure is simple and easy to manufacture, but the viewing angle is limited and stereoscopic effects cannot be achieved
Solution Approach 1:
The display panel transitions from a static flat state to a dynamic bent state through the bend control unit. The panel can be selectively bent along a first direction or a second direction based on user needs, transforming the rigid flat structure into a flexible dynamic structure that adapts to different viewing requirements and enables stereoscopic effects
Solution Approach 2:
The display panel employs a flexible thin film structure that allows bending without damage. This flexible construction enables the panel to be curved in desired directions while maintaining display functionality, resolving the contradiction between structural simplicity and adaptability for stereoscopic display
2Adaptability or versatility
If the display panel is made flexible to enable bending, then viewing angles and stereoscopic effects are improved, but the control of curvature becomes difficult
Solution Approach 1:
The bend control unit acts as an intermediary mechanism between the user and the flexible display panel. It provides controlled pressurization at specific locations to induce bending in desired directions, making the curvature control intuitive and easy to operate while maintaining the flexibility benefits
Solution Approach 2:
The bend control unit applies pressure to segmented regions of the display panel (first region and second region on opposite sides). By independently controlling pressure application to different segments, the system achieves precise directional control over the panel's curvature, simplifying operation
3Manufacturing precision
If pressure is applied to bend the display panel, then the bent state is achieved for better image quality, but the mechanism becomes complex
Solution Approach 1:
The bending function is extracted as a separate, dedicated bend control unit independent of the display panel itself. This modular approach allows the pressure application mechanism to be optimized for its specific function while keeping the display panel design relatively simple, balancing image quality requirements with overall device complexity

AI summary
A display device includes a display panel that can be switched to a plane state or a bent state, and the curvature of the display panel can be easily controlled. The display device includes a display panel configured to display an image and a bend control unit located in the rear of the display panel. The bend control unit bends the display panel toward the front of the display panel by pressurizing two regions on the display panel located on different sides based on the center of the display panel.
