Foldable Display Hinge Support Plate for Crease Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible display panels in foldable electronic devices suffer from poor bending resistance and impact resistance, leading to irreversible creases during repeated folding and unfolding, which affects the flatness and display quality.
Innovation Solution
A hinge mechanism with a flexible display panel that includes a support member with a first support plate positioned between the flexible portion and the moving mechanism, which moves away from the fixing bracket in the flat state and approaches it in the bent state, reducing creases and maintaining panel flatness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display panel is made compact and flexible, then portability is improved, but bending resistance and impact resistance deteriorate, causing creases during repeated folding
Solution Approach 1:
The support structure is divided into multiple support members that can independently move relative to each other, allowing each segment to adapt to the bending requirements of different portions of the flexible display panel during folding and unfolding operations
Solution Approach 2:
The support members are designed to be movable rather than fixed, enabling them to dynamically adjust their positions and orientations in response to the changing geometric requirements of the flexible display panel during folding transitions, thereby maintaining support without creating creases
2Ease of operation
If the flexible display panel is folded repeatedly, then portability is improved, but irreversible creases are generated, deteriorating flatness and display effect
Solution Approach 1:
The support members are positioned and configured in advance to provide optimal support during the folding process, preventing crease formation before it occurs by maintaining proper geometric relationships between support elements during repeated folding and unfolding operations
Solution Approach 2:
The movable support members act as intermediaries between the flexible display panel and the external environment, absorbing and distributing mechanical stresses during folding to prevent direct contact and crease formation on the display panel surface

AI summary
The present application provides a hinge, a flexible display panel, and an electronic device. The electronic device includes a flexible display panel including a flexible portion and a hinge, and the hinge includes a fixing bracket, a rotating mechanism, and a first support plate. When the flexible portion is in a flat state, the first support plate supports the flexible portion to reduce creases of the flexible portion. When the flexible portion is in a bent state, the first support plate is away from the flexible portion to prevent the flexible display panel from being pressed.
