Abstract: A display frame includes a frame body defining a receiving space with an access opening facing forwardly, a holding tray adapted for holding a flat panel device, like a tablet PC, and movable relative to the frame body between an extending position where the holding tray extends forwardly and outwardly of the opening, and a retreat position where the holding tray retreats into the space, a front profile frame movable relative to the frame body between open and closed positions, and a linkage pivoted on the front profile frame and coupled to a key which is disposed on the holding tray such that when the linkage is moved in response to the movement of the front profile frame, the holding tray is moved between the extending and retreat positions.
