DISPLAY DEVICE AND FOLDABLE ELECTRONIC DEVICE

Smart overview of the Invention

The patent application describes a display device designed for foldable electronic devices, such as smartphones. The device features a display panel with distinct areas: a first area, a foldable area, and a second area. These areas are supported by respective plates and a flexible thin-film layer that connects them. The foldable area allows the display to bend around a folding axis, enhancing the device's portability without compromising screen size.

Technical Components

Key components include a first and second plate located on the rear surface of the display panel, separated by the folding area. A flexible thin-film layer is crucial, comprising three portions: one covering the first plate, another covering the second plate, and a third connecting these portions across the folding area. A guide overlays part of this thin-film layer and the second plate, facilitating smooth transitions between folded and unfolded states.

Adhesive Elements

The design incorporates adhesive elements to secure different parts of the device. A first adhesive element attaches the flexible thin-film layer to the first plate. Additional adhesive elements are used between the guide and the second plate, ensuring stability while allowing necessary movement during folding. These adhesives may include double-sided tape or optical clear adhesive, chosen for their specific properties.

Functional Dynamics

The device's functionality is enhanced by its structural dynamics. When transitioning between states, the flexible thin-film layer's portions adjust relative to each other. For example, in an unfolded state, certain layers align on the same plane. The design also includes a step difference compensator to manage changes in thickness across different sections of the display panel.

Design Flexibility

While specific embodiments are detailed, the patent allows for modifications within its scope and spirit. The described elements can vary in arrangement or composition to suit different applications or improve performance. This flexibility ensures that innovations can be integrated without departing from the core invention principles.
