Multi-Hinge Foldable Display Sequencing to Prevent Panel Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible and foldable display devices face interference and potential damage to the display panel and hinge portions when multiple portions are rotated and folded simultaneously, leading to structural damage.
Innovation Solution
The display device incorporates hinge controllers with springs and wires to control the rotation of hinge portions, using stoppers to prevent excessive rotation and interference, ensuring the display panel and hinge portions are protected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple hinge portions are rotated and in-folded simultaneously, then the folding speed and operation efficiency are improved, but interference occurs between portions leading to damage of the display panel and hinge portions
Solution Approach 1:
The stopper mechanism is activated in advance to prevent one hinge portion from rotating before the other has completed its folding sequence. The first stopper prevents the first hinge portion from rotating when the second hinge portion is still in a folded state, and vice versa, thereby eliminating interference damage while maintaining efficient folding operation
Solution Approach 2:
The stopper acts as an intermediary mechanism between the two hinge portions, mediating their rotational movement to prevent interference. The stopper temporarily blocks the rotation of one hinge portion when the other is being folded, ensuring sequential operation without direct conflict between the moving parts
2Reliability
If stoppers are added to control hinge rotation, then damage to the display panel and hinge portions is prevented, but the device complexity increases
Solution Approach 1:
The stopper mechanism is merged with the existing hinge structure, where the stopper is integrated into the hinge assembly rather than being a completely separate component. This integration approach prevents damage functionality while minimizing the increase in overall device complexity by sharing structural elements with the hinge portion

AI summary
A display device is capable of substantially preventing damage to a display panel and a hinge portion, the display device including: a panel support portion including a first support portion, a second support portion, and a third support portion; a first hinge portion connecting the first support portion and the second support portion; a second hinge portion connecting the second support portion and the third support portion; a flexible display panel disposed on the panel support portion; and a hinge controller controlling each of the first hinge portion and the second hinge portion to be rotatable or unrotatable based on a first angle between the second support portion and the first support portion and a second angle between the second support portion and the third support portion.
