Abstract

A display device for an information handling system includes a flexible display screen, a display holder, and a sliding frame component. The flexible display screen is able to be adjusted in between multiple sizes. The display holder includes first and second foldable portions located on distal ends of the display holder. The sliding frame component adjusts the size of the flexible display screen. The sliding frame component includes first and second sliding frames, and a gear. The first sliding frame includes a first adjustment component, and the second sliding frame includes a second adjustment component. The gear is located in between the first and second adjustment components, and guides the first and second sliding frames.
