AI Technical Summary

Technical Problem

Foldable computing devices with hinges face challenges in supporting flexible displays without causing damage from sharp bends, while also maintaining a compact profile for storage and transport.

Method used

A hinge assembly with a virtual pivot link and a slidably attached display support that moves relative to the hinge attachment frame and virtual pivot link, providing additional kinematic freedom and reducing strain on the flexible display.

Benefits of technology

The hinge assembly effectively reduces strain on the flexible display, improves its longevity, and maintains a flat display surface in the unfolded state, while allowing for a teardrop profile during folding to prevent sharp bends.

Abstract

A hinge assembly rotatably coupling a first portion of a foldable display device to a second portion of the foldable display device includes a hinge spine and a hinge attachment frame attached to the first portion. A virtual pivot link connects the hinge attachment frame to the hinge spine, wherein the virtual pivot link is movably coupled to the hinge spine via a virtual pivot. A display support is slidably attached to the virtual pivot link, such that the display support moves relative to the hinge attachment frame and the virtual pivot link during movement of the first portion relative to the second portion.
