The structural diagram shows that there is a telescopic structure composed of springs and sliding bars inside the LG Rollable fuselage, which is used to control the extension speed of the reel flexible screen and lock the position. Specially, it can be deployed unilaterally or bilaterally, and can obtain about twice the visible area after full deployment.

However, for scroll screen mobile phones, the unilateral extension structure similar to OPPO X 2021 will already occupy a lot of internal space. LG's new phone is more likely to be similar to the promotional film Egg, which uses the unilateral expansion form to provide different screen proportions through two sections of telescopic structure.
