Slidable Display Segment Coupling for Curvature Defect Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slidable display devices experience damage and display defects due to repeated curvature of the second display region, leading to deteriorated performance and space inefficiency as the accommodation space decreases.
Innovation Solution
A slidable display device design featuring a display module with a first and second display region, a support layer, and segment members with specific protrusions and coupling grooves that engage and guide each other to maintain alignment during sliding, preventing misalignment and curvature defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the second display region is repeatedly curved and uncurved during sliding in and out, then the slidable display device can accommodate the display region in a narrow space, but the display module may be damaged and display performance deteriorates
Solution Approach 1:
The support layer is divided into multiple segment members (first, second, third, fourth segment members) that can independently move and accommodate the curved display region. Each segment member has coupling parts that engage with each other to maintain relative positions while allowing individual movement, enabling the support structure to adapt to the repeated curvature without damage
Solution Approach 2:
The coupling parts between segment members are designed to allow relative movement and engagement/disengagement during sliding operations. The coupling grooves and protrusions create a dynamic connection that accommodates the repeated curvature and uncurvature of the display region, maintaining structural integrity through controlled motion rather than rigid fixation
2Volume of moving object
If the accommodation space is decreased to improve space efficiency, then the slidable display device becomes more compact, but the second display region cannot be properly accommodated without causing damage
Solution Approach 1:
By segmenting the support layer into multiple independent segment members with coupling parts, the invention achieves compact accommodation space while maintaining precise alignment. Each segment can be independently positioned and coupled to neighbors, ensuring manufacturing precision is maintained even in a reduced overall device size
Solution Approach 2:
The segment members are arranged in a nested configuration where the first and second segment members are disposed on one side of the curved display region while the third and fourth segment members are disposed on the other side, with coupling parts interengaged. This nesting approach maximizes space efficiency while preserving alignment precision through the coupled segment structure

AI summary
A display device includes: a display module including a first display region and a second display region extending from a side of the first display region, where one portion having a curved shape is defined in a portion of the second display region; a support layer disposed on a bottom surface of the display module; and a plurality of segment members, each including a center part, a support part extending from the center part and making direct contact with a bottom surface of the support layer in a region overlapping the second display region, an extension part extending from the center part in a direction intersecting an extension direction of the support part and defining a coupling groove together with the support part, and a coupling part extending from the center part in a direction opposite to the coupling groove.
