Foldable Display Support Structure for Bending Portion Flatness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices with flexible display panels face issues of poor rigidity and bulging at the bending portion due to inadequate support, leading to poor flatness and short service life.
Innovation Solution
A support device is designed with a rotating shaft support and multiple support components that connect to both non-bending and bending portions of the flexible display panel, providing comprehensive support to prevent bulging and ensure flatness when folded or unfolded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display panel is used to enable folding, then adaptability and portability are improved, but rigidity and flatness deteriorate at the bending portion
Solution Approach 1:
The support structure is segmented into multiple components: a first support connected to the first non-bending portion, a second support connected to the second non-bending portion, and a rotating shaft support connecting both supports. This segmentation allows each component to perform its specific function while collectively providing comprehensive support to the bending portion, thereby improving rigidity without compromising folding capability.
Solution Approach 2:
The support structure extends in multiple dimensions by incorporating support components that connect to the bending portion from different spatial positions. The rotating shaft support with its rotating shaft and multiple support components creates a three-dimensional support network that reinforces the bending portion without interfering with the folding motion.
2Ease of operation
If the bending portion is made more flexible for folding, then ease of operation is improved, but stability and flatness deteriorate
Solution Approach 1:
The rotating shaft support acts as an intermediary mechanism between the first support and the second support. It includes a rotating shaft that can rotate relative to the support beam, allowing the structure to accommodate folding motion while the support components connected to the bending portion provide continuous stabilization. This intermediary mechanism enables easy folding operation while maintaining stability and flatness throughout the folding process.
3Strength
If support is added to the bending portion, then rigidity and flatness are improved, but device complexity increases
Solution Approach 1:
The rotating shaft support serves multiple functions simultaneously: it connects the first support and the second support, provides a rotating mechanism for folding motion, and supports the bending portion through connected support components. This multi-functionality reduces the need for separate dedicated support structures, thereby improving rigidity while limiting the increase in device complexity.
4Reliability
If comprehensive support is provided to prevent bulging, then reliability and service life are improved, but manufacturing complexity increases
Solution Approach 1:
The support structure incorporates dynamic elements, specifically the rotating shaft that can rotate relative to the support beam. This dynamic design allows the structure to adapt to different folding states while maintaining support for the bending portion. The dynamic mechanism provides comprehensive support to prevent bulging and extend service life, while the modular rotating shaft design facilitates easier manufacturing compared to rigid fixed support structures.
