Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing support frames with fixed lengths exert excessive force on flexible display screens when folded, leading to breakage and reduced lifespan.
Innovation Solution
A display device with a telescopic portion that adjusts its length in response to the bending state of the display panel, featuring a support portion with a first and second support portion, a telescopic portion, and an adjusting portion to control the movement of the telescopic portion, ensuring optimal force distribution during folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed-length support frame is used, then the structural simplicity is maintained, but the display screen receives excessive force during folding which causes breakage and reduces lifespan
Solution Approach 1:
The support frame transitions from a fixed-length structure to a telescopic structure with movable components. The telescopic portion includes a first support portion, a second support portion, and a telescopic portion that can extend and retract along the folding direction, enabling the support frame to dynamically adjust its length according to the bending state of the display screen during folding operations.
Solution Approach 2:
The key parameter that changes is the length of the support frame. The telescopic portion allows the distance between the first support portion and the second support portion to vary, with the telescopic portion's length changing in response to the bending state of the display screen, thereby adapting the support frame's dimensions to different operational states.
2Ease of manufacture
If the support frame length is fixed, then manufacturing simplicity is maintained, but the force distribution on the display screen becomes excessive during both inward and outward folding
Solution Approach 1:
The support frame incorporates movable components including a telescopic portion with first and second support portions that can adjust their relative positions. This dynamic structure allows the support frame to adapt its length and force distribution characteristics based on the folding state, reducing excessive force on the display screen while maintaining manufacturing feasibility through standardized telescopic mechanisms.
3Device complexity
If a fixed-length support frame is used, then the device structure remains simple, but the display screen experiences excessive force leading to breakage
Solution Approach 1:
The support frame employs a telescopic mechanism with movable connections between the first support portion, second support portion, and telescopic portion. This dynamic configuration enables the support frame to adjust its length in response to the display screen's bending state, thereby protecting the display screen from excessive force and maintaining its structural integrity during folding operations.

Function Achieved in This Case
The adjustable telescopic portion reduces the risk of breakage by maintaining appropriate force levels during both inward and outward folding, thereby extending the lifespan of the display device.
Implementation Method 1
a length of a part of the telescopic portion corresponding to the bending portion changes following a bending state of the bending portion
Implementation Method 2
two adjacent support shafts are movably connected by one of the rotating shafts

AI summary
A display device is provided, which has a display panel, a support portion, and a telescopic portion. The display panel has a bending portion for bending so as to fold the display panel inwardly or outwardly. The support portion supports and is connected to the display panel. The telescopic portion is at least disposed opposite to the bending portion, and at least one end of the telescopic portion extends to be movably connected with the support portion, such that a length of a part of the telescopic portion corresponding to the bending portion changes following a bending state of the bending portion.
