Computing device slider plate

A computing device foldable through 360 degrees, the computing device comprising:

• a flexible display supported by a first display-supporting frame and a second display-supporting frame, the first display-supporting frame comprising a first backplate opposite to the flexible display, the second display-supporting frame comprising a second backplate opposite to the flexible display, the first display-supporting frame rotatably coupled to the second display-supporting frame via a spine that comprises an outer spine plate;
• a translation mechanism coupled to the first display-supporting frame and configured to translate the first display-supporting frame relative to the spine as the first display-supporting frame is rotated relative to the spine, the translation mechanism comprising a support structure rotatably coupled to the spine, wherein the first display-supporting frame is moveably coupled to the support structure;
• and
• a first moveable slider plate biased into contact with the outer spine plate to cover at least a portion of an aperture at least partially defined by a first leading edge of the first backplate and the outer spine plate, wherein the first moveable slider plate is biased against the support structure toward the spine.
