Foldable Display Support Sheets for Step-Free Bending Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with flexible displays face challenges in stabilizing the display during bending due to mechanical components on the back surface, which can cause operational discomfort and potential failure from impacts.
Innovation Solution
The apparatus includes a support component with movable sheet-like members that stabilize the display by covering steps on the support surface, ensuring a smooth operational feel and protecting against impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a hinge device component is disposed on the back surface side of the bending region, then the display can be supported during bending, but a step is formed on the back surface which deteriorates operational feeling and causes reliability issues
Solution Approach 1:
A filler component is introduced as an intermediary element between the hinge device component and the back surface of the display. This filler component fills the gap created by the hinge component, creating a flush surface that eliminates the step while allowing the hinge component to remain in place for structural support.
Solution Approach 2:
The invention changes the geometric parameter of the support surface by adding the filler component, which modifies the surface profile from having a step to having a flush surface. This parameter change resolves the contradiction between maintaining the hinge component for support stability and eliminating the step for operational comfort.
2Length of moving object
If the flexible display is made extremely thin to reduce size, then the display can be more compact, but the display becomes weak to impact and prone to failure
Solution Approach 1:
The filler component acts as a cushioning element that is positioned in advance to protect the thin flexible display from impact. By filling the gap and creating a more robust support structure, the filler component absorbs and distributes impact forces before they can reach the fragile display, thereby enhancing reliability without increasing display thickness.
