Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing curved liquid crystal displays have fixed curvature, which cannot be adjusted, limiting their adaptability and user experience, particularly in terms of viewing angles and image distortion.
Innovation Solution
A composite back cover and backlight module with adjustable curvature, featuring extensible control devices between a back cover and a fixing plate, allowing the curvature to be adjusted by stretching or shortening these devices, thereby modifying the distance between the back cover and the fixing plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed curvature is used in the liquid crystal display, then the manufacturing process is simplified and structural stability is improved, but the adaptability and user experience are limited due to inability to adjust viewing angles and reduce image distortion
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed curvature structure into an adjustable curvature structure. The back cover is designed to be bendable along a curvature line, and extensible control devices allow the curvature radius to be dynamically adjusted between a first curvature radius and a second curvature radius. This enables the display to adapt to different viewing conditions while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent implements parameter changes by allowing the curvature radius of the back cover to vary between a first curvature radius and a second curvature radius. The extensible control devices modify the physical parameters of the back cover (curvature radius and distance from the fixing plate) to achieve different curvature states, thereby improving adaptability without fundamentally changing the structural design.
2Adaptability or versatility
If the back cover is made rigid to ensure structural stability, then manufacturing precision is improved, but the ability to adjust curvature is lost
Solution Approach 1:
The back cover is designed with dynamic characteristics, allowing it to bend along a curvature line while maintaining structural integrity. The extensible control devices provide controlled flexibility, enabling the back cover to adjust its curvature radius between predetermined values while remaining stable in each adjusted state.
Solution Approach 2:
The back cover is designed as a flexible structure that can bend along a curvature line. This flexible design allows the back cover to adapt to different curvature requirements while the extensible control devices provide the necessary support and stability to maintain the desired curved shape during use.
3Adaptability or versatility
If extensible control devices are added to enable curvature adjustment, then adaptability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent uses extensible control devices to provide dynamic curvature adjustment capability. These devices connect the back cover to the fixing plate and can be extended or retracted to change the curvature radius. This approach adds adjustment functionality while keeping the manufacturing process relatively straightforward by using standardized extensible mechanism components.
Solution Approach 2:
The extensible control devices act as intermediary components between the back cover and the fixing plate. They mediate the relationship between these two parts, enabling curvature adjustment while simplifying the overall manufacturing process by using modular, interchangeable components rather than requiring custom-designed adjustment mechanisms.

AI summary
A composite back cover with adjustable curvature used in a liquid crystal display with adjustable curvature is provided. The composite back cover includes a fixing plate; a back cover having a central portion secured to the fixing plate; and at least two extensible control devices disposed between the back cover and the fixing plate and respectively arranged at two sides of the central portion. The extensible control devices are stretched or shortened to adjust a distance between the back cover and the fixing plate so as to adjust curvature of the back cover. A backlight module is also provided. The distance between the back cover and the fixing plate is adjusted by stretching or shortening the extensible control devices so as to adjust the curvature of the liquid crystal display.
