Slidable Display Support Guide to Prevent Panel Lift-Off and Creases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices experience lift-off and resultant creases, leading to decreased touch sensing capability and operation failures when the display panel is lifted off and pressed.
Innovation Solution
A slidable display device with a support guide coupled to a slidable structure, including roll belts and a support member, stabilizes the display panel during sliding, preventing lift-off and creases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is made slidable to enable transformation between folded and unfolded states, then the adaptability and versatility of the display device are improved, but the stability of the display panel is worsened, causing lift-off and creases
Solution Approach 1:
A support guide is introduced as an intermediary component between the display panel and the sliding structure. The support guide includes a guide body with a guide groove that receives and guides the sliding structure, preventing lateral displacement and lift-off of the display panel while allowing controlled sliding motion. This mediator resolves the contradiction by enabling transformation while maintaining panel stability.
Solution Approach 2:
The support guide extends in the thickness direction (third dimension) of the display panel, with the guide groove positioned to provide support from below. By utilizing the thickness direction for support rather than only planar support, the structure prevents lift-off and creases while allowing sliding motion in the plane of the panel, thus resolving the stability issue during transformation.
2Ease of operation
If the display panel is lifted off during sliding, then the slidable function is achieved, but the touch sensing capability deteriorates due to creases and operation failures
Solution Approach 1:
The support guide acts as a mediator that prevents harmful lift-off and crease formation while still allowing the necessary sliding motion for transformation. By guiding the sliding structure through a predefined groove, it ensures the display panel remains stable and maintains its flatness, thereby preserving touch sensing capability and operational reliability during the slidable transformation.
3Stability of the object's composition
If a support structure is added to prevent lift-off, then the stability of the display panel is improved, but the device complexity increases
Solution Approach 1:
The support guide is segmented into a guide body and a sliding structure with distinct functions. The guide body provides the groove for guidance, while the sliding structure contains the rolling elements. This segmentation allows each component to be optimized independently and simplifies the overall design by clearly defining the roles of each part, reducing complexity while maintaining stability.
Solution Approach 2:
The support guide and sliding structure are designed with thin-walled or lightweight constructions that provide the necessary mechanical support and guidance functions without adding excessive weight or complexity. The guide groove and sliding components are formed with minimal material while maintaining structural integrity, thus improving stability without significantly increasing device complexity.

AI summary
A display device includes a display panel, a frame disposed on a back surface of the display panel, slidable plate disposed to overlap, at least in part, the frame, a slidable structure includes a plurality of roll belts, and a support guide disposed between the frame and the slidable plate. Each of the plurality of roll belts includes a bar extending in a straight line and a ring extending from one surface of the bar and providing an accommodation hole to which the support guide is coupled.
