Flexible Display Electromagnet Shape Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat panel displays face challenges in maintaining a fixed shape due to their rigid substrates, which hinder flexibility and increase weight and thickness.
Innovation Solution
Incorporating electromagnets in the non-display area of a flexible display panel, which generate forces to hold the panel in desired shapes such as rolled or folded states when powered, eliminating the need for separate fixing members and reducing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid substrates are used in flat panel displays, then structural stability is improved, but flexibility and weight are worsened
Solution Approach 1:
The patent replaces rigid substrates with flexible substrates that can be rolled or folded, directly addressing the contradiction by using thin film structures that provide both flexibility and sufficient mechanical stability without the weight penalty of traditional rigid materials
2Shape
If separate fixing members are added to maintain display shape, then shape fixation is improved, but device complexity is worsened
Solution Approach 1:
The patent integrates the fixing function directly into the flexible display panel structure itself, eliminating the need for separate fixing members. The flexible substrate and electromagnet work together as an integrated system to maintain shape, reducing overall device complexity while achieving the desired shape fixation
3Shape
If additional fixing components are incorporated, then shape maintenance is improved, but manufacturing cost is worsened
Solution Approach 1:
The flexible display panel uses its own structural components (flexible substrate and electromagnet) to maintain shape, eliminating the need for additional fixing components. This self-service approach reduces part count and assembly complexity, directly lowering manufacturing costs while maintaining shape effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible displays to be easily fixed in various shapes without additional fixing components, reducing size, weight, and manufacturing costs, while allowing for easy return to original shape when power is cut off.
Implementation Method 1
at least one electromagnet in the non-display area... When the power is supplied to the electromagnet, the electromagnet may generate a force to pull the metal plate

AI summary
A flexible display includes a flexible substrate, a metal material coupled to the flexible substrate, and at least one electromagnet coupled to the flexible substrate. The electromagnet generates a force to attract the metal material when the flexible substrate changes from a first state to a second state. The force assists in holding the flexible substrate in the second state, which may be a rolled state, folded state, or another changed state. The flexible substrate includes a display area corresponding to a plurality of pixels for generating an image.
