The present disclosure discloses a bidirectional flipping mechanism for flipping a TV cabinet and a flip TV cabinet. The bidirectional flipping mechanism includes a driving unit mounted on a mounting base for driving at least one of a first flipping member and a second flipping member to respectively pivot around a first pivot shaft and a second pivot shaft with respect to the mounting base, and thus when the bidirectional flipping mechanism is applied to the flip TV cabinet, an upper part of a vertically placed laser TV on the support plate and the top of the support plate can be as close as possible to the top plate of a cabinet body of the flip TV cabinet, so as to reduce a total height of the cabinet body and avoid a large gap between the support plate and the top plate.

An adapter plate permits an arm mount with a single abutment plate to support two monitors. The adapter plate includes a first hole, a second hole, and a third hole. The holes may be part of a first set of holes, a second set of holes, and a third set of holes, respectively. Each of the sets of holes is preferably configured in a symmetric pattern compliant with VESA standard configurations for flat panel monitor mounts. One set of holes aligns with the abutment plate on the arm mount and the other two sets of holes align with the two monitors respectively to receive support members, such as bolts, therethrough to couple the two monitors to the single abutment plate on the arm mount.

The operator desk includes at least one work top having one main work surface with a longitudinal main extension. The work top is attached by at least one leg arrangement extending between the desk top and a base foundation; at least one first set of display monitors arranged on a mount supported by at least two supporting legs and having one lower side facing towards, and one upper side facing away from the base foundation. The supporting legs with adhering first set of monitors are movable along a first extension. The operator desk further includes at least one light-emitting element contained in a casing attached to the upper side by at least one mounting arm. A central control device adjusts the mounting arm so that the light-emitting element maintains a desired position along the first extension when the supporting legs with adhering display monitors are moved along the first extension.

A kit for aligning and fixing within a first tolerance range a support structure for a tiled display wall. The support structure comprises a plurality of channel profiles arranged vertically, and a plurality of frame assemblies configured to be arranged in a first row of frames. The kit further comprises a plurality of bottom supports to be aligned within a second tolerance range larger than the first tolerance range, and configured to be fixed to the channel profiles, a plurality of top supports configured to be fixed to the channel profiles, and supporting means comprising a plurality of spring loaded suspension blocks configured to be attached to the bottom supports, such that, when the frame assemblies are laid on the supporting means, the supporting means support the frame assemblies while aligning and fixing the frame assemblies, within the first tolerance range, to the top supports.
