Rollable Display Connection Part Stress Management

The patent introduces a connection part as an intermediary component between the flexible display panel and the grip part. This connection part includes a connection polarization film that extends from the polarization film, serving as a mediator to transfer and distribute stress away from the display pixels, thereby preventing pixel bending and malfunction while maintaining structural integrity.

The patent segments the connection structure by separating the connection function from the display function. The connection part is divided into distinct components including the connection base substrate, connection polarization film, and connection upper protective film, allowing each segment to perform its specific function independently while collectively solving the stress distribution problem.

The patent merges multiple functions into the connection part: stress distribution, polarization maintenance, and structural connection. By combining the connection base substrate, connection polarization film, and connection upper protective film into an integrated connection assembly, the design achieves improved display quality while managing overall device complexity through functional integration.

The connection polarization film performs multiple functions simultaneously: it maintains the polarization state for image clarity, provides structural connection, and distributes stress. This multi-functionality reduces the need for separate dedicated components for each function, thereby improving image clarity while managing the quantity of components.
