Nested Guide Rails for Flexible Display Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices, particularly OLEDs, face challenges in flexible and compact design solutions that allow for easy deployment and support of the display panel while maintaining a flat and stable surface for image emission.
Innovation Solution
A display device comprising guide plates, guide rails, and supporting plates that slide to form an enlarged planar surface, allowing the flexible display panel to be unfolded and supported, with the supporting plates being fixed to the guide plates at specific positions and sliding along rails to create a continuous surface for the display panel to be maintained flat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display panel is made flexible and stored in a compact form, then the device portability and storage efficiency are improved, but the structural complexity increases to enable deployment and support mechanisms
Solution Approach 1:
The supporting plates are nested within the guide plates when not in use, with the first supporting plate positioned within the first guide plate and the second supporting plate positioned within the second guide plate. This nesting arrangement allows the entire support structure to be compacted into a minimal volume while maintaining the capability to deploy a large planar surface when needed.
Solution Approach 2:
The supporting plates are designed to be movable along the guide rails, transitioning from a compact stored position to an extended deployed position. The first supporting plate slides along the first guide rails, and the second supporting plate slides along the second guide rails, enabling dynamic transformation between compact and expanded states to support the flexible display panel.
2Area of stationary object
If the supporting plates are extended to form a large planar surface, then the display area and image quality are improved, but the device dimensions increase
Solution Approach 1:
The support structure is divided into multiple segments: first and second guide plates, first and second supporting plates, and corresponding guide rails. These segmented components can be independently positioned and adjusted along their respective guide rails, allowing the system to achieve a large total display area while maintaining a compact overall device length through strategic arrangement of the segments.
Solution Approach 2:
The supporting plates are arranged in different spatial dimensions and positions. The first supporting plate is positioned within the first guide plate at a first position, while the second supporting plate is positioned within the second guide plate at a second position. This multi-dimensional arrangement allows the system to expand the display area without proportionally increasing the device length in any single dimension.
3Ease of operation
If the supporting plates are made movable to enable deployment, then the ease of operation is improved, but the reliability of maintaining a flat stable surface decreases
Solution Approach 1:
The guide rails are designed with precise geometric constraints and tolerances to ensure that the supporting plates maintain proper alignment and positional accuracy throughout their movement range. The guide plate structures incorporate features that pre-establish the correct geometric relationships between components, ensuring that when the supporting plates are extended, they automatically form a flat and stable surface without requiring additional active control or adjustment mechanisms.

AI summary
A display device includes first and second guide plates facing each other, a pair of first and second guide rails disposed in the first and second guide plates, a first supporting plate disposed between the first guide rails and of the first and second guide plates, the first supporting plate having opposite end portions fixed to a first position of the first and second guide plates, a second supporting plate having opposite end portions coupled to the pair of first guide rails, a third supporting plate having opposite end portions coupled to the pair of second guide rails, and a display panel supported by at least one of the first to third supporting plates. The pair of first guide rails extends from the first position to a second position. The pair of second guide rails extends from the first position to a third position.
