Teardown of unreleased LG Rollable shows why rollable phones aren't a thing

A teardown of LG's unreleased Rollable reveals a highly complex motorized mechanism that expands the frame.

The device uses two motors on a geared track and includes multiple motors, spring arms, tracks, and a screen that loops around the back.

That internal complexity would have increased manufacturing costs and raised durability concerns, which likely prevented a commercial launch.

Other companies also demoed rollable concepts but none released a rollable phone; LG instead ended its phone business with the Wing.
