Multi-Hinge Display Panel With Torque-Ordered Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Folding display devices that require multiple folds are prone to damage if not folded in a specific order, leading to vulnerability and potential structural failure.
Innovation Solution
A display panel design featuring at least three middle frames connected by two hinges with different torques, allowing for a preset folding order where the hinge with lower torque closes first, followed by the higher torque hinge, ensuring the panel is folded correctly and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple hinges are used to enable multiple folds, then the display panel can be folded into smaller configurations, but the device becomes vulnerable to damage if folded in incorrect order
Solution Approach 1:
The patent applies parameter changes by setting different torque values for different hinges. The first hinge has a first torque and the second hinge has a second torque that is greater than the first torque. This torque parameter differentiation ensures that when folding force is applied, the hinges close in a predetermined sequence (first hinge then second hinge), preventing incorrect folding orders that would cause damage. This resolves the contradiction by maintaining reliability through controlled folding sequence while preserving adaptability through multiple folding configurations.
2Reliability
If hinges with different torques are used to control folding sequence, then the device achieves fool-proof folding, but the device complexity increases
Solution Approach 1:
The patent applies local quality by making each hinge have a specific, differentiated torque characteristic tailored to its position in the folding sequence. The first hinge is designed with a lower torque suitable for initial folding, while the second hinge has a higher torque for subsequent folding. This localized differentiation of torque properties achieves reliable folding sequence control without requiring a complex centralized control system, thus resolving the contradiction between reliability and device complexity.

AI summary
The present application provides a display panel and an electronic device, the display panel includes at least three middle frames and at least two hinges, every two adjacent said middle frames being rotatably connected, each of said hinges being connected to two adjacent said middle frames, and torques of any two adjacent hinges are different. A hinge with a small torque is closed first, and a hinge with a large torque is closed later, so that the display panel can be folded according to a preset folding order, and the problem that the existing folding display device is vulnerable to being folded is solved.
