Flexible Display Support Structure With Drive Belt Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices lack an efficient mechanism to support the display module when extended outside a housing, leading to instability and potential damage.
Innovation Solution
A display device with a lifting part disposed on the rear surface of the display module, connected via a drive belt that moves along a guide groove, allowing the display module to be extended and retracted while being supported more flatly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display module is extended outside the housing without a lifting part, then the device structure is simpler, but the display module lacks stability and support when extended
Solution Approach 1:
The lifting part is divided into multiple support parts (first support part, second support part, etc.) that can move independently along the guide groove. Each support part provides localized support to the display module, allowing the system to achieve stability through distributed support rather than a single rigid structure.
Solution Approach 2:
The support parts are designed to move dynamically along the guide groove in response to the extended state of the display module. When the display module is extended, the support parts automatically adjust their positions to provide appropriate support, transitioning from a static to a dynamic support system.
2Ease of operation
If the display module is extended outside the housing, then user accessibility is improved, but the display module becomes vulnerable to damage
Solution Approach 1:
The lifting part provides preemptive support to the display module before it can be damaged during extension. The support parts are positioned to catch and support the display module as it extends, preventing accidental drops or damage from improper handling.
Solution Approach 2:
The lifting part acts as an intermediary mechanism between the display module and the external environment. It provides a controlled interface that allows the display module to be extended for user accessibility while protecting it from direct exposure to harmful factors such as accidental drops or improper handling.
3Reliability
If a lifting part with multiple support parts is used to support the display module, then stability is improved, but the device complexity increases
Solution Approach 1:
The lifting part is designed to perform multiple functions: it supports the display module during extension, guides its movement along the groove, and provides protective cushioning. This multi-functionality reduces the need for separate components for each function, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The support parts, guide groove, and protective mechanisms are merged into a single integrated lifting part structure. Rather than having separate support elements, guide mechanisms, and protective features, they are combined into one cohesive component that provides comprehensive support while minimizing the number of discrete parts.

AI summary
A display device includes: a display module, a lifting part disposed on a rear surface of the display module and connected to the display module, and a drive belt connected to the lifting part and which moves in a first direction to extend and retract the lifting part in the first direction. The drive belt moves along a guide groove that is defined in the lifting part and that is open in the first direction.
