Variable-Curvature Display Panel for Multi-Viewer Distortion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Curved TVs often occupy a lot of space and can cause screen distortion for viewers not located at the center of curvature, leading to reduced immersion and increased eye fatigue.
Innovation Solution
A display apparatus with a display panel that can be bent dynamically, controlled by a controller using information such as remote controller manipulation, voice signals, and user location, to adjust the curvature of the panel and minimize distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a curved TV uses a concavely curved display panel, then the three-dimensional effect and user immersion increase, but the device occupies more space and causes screen distortion for users not at the center of curvature
Solution Approach 1:
The display panel transitions from a fixed curved state to a dynamically adjustable state, capable of switching between flat and curved configurations. This allows the system to adapt its shape based on viewing requirements, resolving the contradiction between immersion (achieved through curvature) and space efficiency (achieved through flat configuration).
Solution Approach 2:
The curvature parameter of the display panel is made variable rather than fixed. By controlling the degree and direction of bending, the system can optimize the balance between providing immersive curved viewing experience and maintaining space efficiency, while also compensating for screen distortion through adaptive curvature adjustment.
2Adaptability or versatility
If a curved TV uses a concavely curved display panel, then the three-dimensional effect and user immersion increase, but screen distortion occurs for users not located at the center of curvature
Solution Approach 1:
The display panel employs dynamic bending control with independent curvature adjustment in different directions. This allows the system to adapt the curvature profile to match the distribution of viewers, ensuring that the three-dimensional effect is maintained while minimizing screen distortion for multiple viewing positions simultaneously.
Solution Approach 2:
Different regions of the display panel can be bent to different degrees and in different directions. This localized curvature control allows optimization of the three-dimensional effect in areas where viewers are present while reducing distortion in other regions, enabling multi-user viewing without compromising image quality.
3Adaptability or versatility
If a curved TV uses a concavely curved display panel, then the user immersion increases, but eye fatigue increases for users not at the optimal viewing position
Solution Approach 1:
The display panel dynamically adjusts its curvature based on detected user positions and viewing conditions. This ensures that users at various locations experience an optimized curved display that maintains immersion while reducing screen distortion and eye fatigue by adapting the curvature to match the actual viewing geometry.

AI summary
A display apparatus is disclosed that includes a display panel and a controller. The display panel includes a first edge extending in a first direction, a second edge extending in a second direction that intersects the first direction, and a display area where an image is displayed. The controller is configured to obtain information to bend the display panel and, in response, to bend the display panel to a bent display panel. In the bent display panel, the first edge has a first display-panel curvature and the second edge has a second display-panel curvature.
