Flexible Display Electromagnet Shape Control

The patent applies the dynamics principle by transitioning from a static preset curvature display to a dynamic shape-adjustable display. Electromagnets are integrated behind the flexible display screen to actively control and change the display's curvature and shape during operation, enabling the display to adapt to different shapes based on user needs rather than being fixed during manufacturing.

The patent replaces traditional mechanical curvature adjustment mechanisms with an electromagnetic field-based system. Instead of using physical levers, springs, or mechanical actuators to change display shape, the invention uses electromagnets to generate magnetic fields that interact with magnetic particles or layers within the flexible display structure, enabling shape control through electrical signals rather than mechanical means.

The patent applies universality by designing the electromagnet system to perform multiple functions simultaneously. The same electromagnet array controls various aspects of display shape including curvature, folding angles, and surface topology. This multi-functional approach reduces the need for separate mechanisms for each shape adjustment, thereby managing manufacturing complexity while achieving versatile shape control.

The patent implements the nested doll principle by integrating the electromagnets within or behind the flexible display structure itself. The electromagnet system is embedded in a compact arrangement where components are nested within each other, with the electromagnet array positioned close to the display surface without adding significant external bulk. This nesting approach minimizes the physical footprint and simplifies the overall manufacturing process.
