Foldable Display Support Structure for Dual-Sided Fixed-Angle Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to simultaneously display a screen on both the front and rear surfaces and maintain a fixed shape after folding, and they have a prominent lower bezel that affects aesthetic appeal and usability.
Innovation Solution
A display device with a display panel divided into three areas - a first and second non-folding area for front and rear surface display, and a folding area with a rounded support structure, along with a bottom cover and support portions to maintain a fixed shape and reduce the lower bezel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device is designed to fold like paper, then space utilization and design flexibility are improved, but the device cannot maintain a fixed shape and stable display angle
Solution Approach 1:
The support structure is divided into multiple segments: a first support portion, a second support portion, and a third support portion connected between them. This segmentation allows the structure to accommodate the folded display panel while maintaining stability at each segment, resolving the contradiction between folding adaptability and fixed shape maintenance.
Solution Approach 2:
The third support portion is nested between the first and second support portions, creating a hierarchical support system. This nesting arrangement allows the folded display panel to be securely held within the support structure, maintaining a fixed shape while preserving the folding capability.
2Adaptability or versatility
If the display panel is folded to enable dual-sided display, then versatility is improved, but the lower bezel area increases affecting aesthetic appeal
Solution Approach 1:
The support structure extends into the vertical dimension with the third support portion positioned between the first and second support portions. This three-dimensional arrangement allows the folded display to achieve dual-sided display capability while minimizing the horizontal footprint, thereby reducing the lower bezel area and improving aesthetic appearance.
3Manufacturing precision
If a rounded support structure is used for the folding area, then display quality and shape maintenance are improved, but manufacturing complexity increases
Solution Approach 1:
The third support portion is designed with a rounded upper surface that matches the curvature of the folded display panel. This curved geometry maintains the precise folded shape of the display while the modular connection to the first and second support portions keeps the overall manufacturing process manageable through standardized joining techniques.

AI summary
Provided is a display device. The display device comprises a display panel including a display area including a first non-folding area, a second non-folding area, and a folding area located between the first non-folding area and the second non-folding area; a first support portion supporting the first non-folding area of the display panel; a second support portion supporting the second non-folding area of the display panel; a third support portion fastened between the first support portion and the second support portion and having a rounded upper surface to support the folding area of the display panel; and a bottom cover located in a direction opposite to the third support portion and fastened to the first support portion and the second support portion.
