Solution Overview
Problem
Existing display devices with curved structures face challenges in providing optimal user immersion when multiple people watch, as they may need to switch between curved and flat modes for convenience.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display module is bent to improve immersion, then user immersion is improved, but convenience for multiple viewers deteriorates
Solution Approach 1:
The display module is designed with dynamic curvature adjustment capability, allowing it to switch between bent and flat states. A bending module with links and a moving block enables the display to change its curvature dynamically based on viewing requirements, resolving the contradiction between immersion (bent state) and multi-viewer convenience (flat state).
Solution Approach 2:
The curvature parameter of the display module is made variable rather than fixed. The system adjusts the curvature parameter between different states (bent/flat) to optimize for different usage scenarios, allowing the same display to provide both high immersion for single viewers and convenience for multiple viewers.
2Ease of operation
If the display module is kept flat to improve viewing convenience, then convenience for multiple viewers is improved, but user immersion deteriorates
Solution Approach 1:
The display module dynamically adjusts its curvature state based on operational context. When image viewing is detected, the display bends to enhance immersion; when not in use or for general purposes, it remains flat for viewing convenience. This dynamic adaptation resolves the contradiction between convenience and immersion.
Solution Approach 2:
The controller detects whether an image is being output and uses this feedback to determine the appropriate display curvature state. When image output is detected, the display transitions to a bent state for immersion; otherwise, it maintains a flat state for convenience, creating a feedback-driven adaptation system.
3Adaptability or versatility
If ambient lights are added to enhance visual effects, then user immersion is improved, but device complexity increases
Solution Approach 1:
The LED bars serve multiple functions: they provide ambient lighting to enhance visual effects, indicate operational status, and create immersive atmosphere. By making the lighting component multi-functional, the patent adds visual enhancement capability without proportionally increasing device complexity.
Solution Approach 2:
The LED bars can render different colors based on the display module's curvature state and operational mode. This color-changing capability enhances visual effects and user immersion while using a relatively simple LED-based implementation, minimizing the increase in device complexity.
