A display comprises a display surface formed from a plurality of display modules arranged in proximity, each display module comprising a plurality of light-emitting elements configured to collectively display one or more of video, graphical, or textual information, and a support array onto which the plurality of display modules is mounted to form the display surface. The support array comprises a plurality of tension members, a plurality of support members arranged in an array, each of the plurality of support members comprising a mounting face and each being supported by at least one of the plurality of tension members. Each of the tension members is suspended either from a support structure or another one of the support members, and each of the display modules is coupled to the mounting face of one or more of the support members.

An adjusting mechanism for tile display screens and a tiled display device are provided. The adjusting mechanism for tile display screens is configured to adjust a gap between two adjacent tile display screens, and includes first support plates, a second support plate, and adjusting fixtures. The first support plates are used to fix the tile display screens in one to one correspondence and are movably connected to the second support plate. Each adjusting fixture is operable to be connected between two adjacent first support plates and includes two adjusting members in threaded connection. A threaded connection length between the two adjusting members is adjustable so that the gap between at least two tile display screens is adjusted.

A display system includes a first display coupled to a roller and a second display coupled to the roller such that the first and second displays can be rolled about the roller for storage and transportation and unrolled from the roller to form a large area display. The second rollable display can be rolled about the roller with a rear surface of the second rollable display in direct contact with an outer surface of the roller and the first rollable display can be rolled about the roller with a front surface of the first rollable display in direct contact with a front surface of the second rollable display. First and second flexible films, first and second source printed circuit boards, first and second flexible cables, and first and second control printed circuit boards can be located inside the roller.

A device substrate comprising a substrate, a first pad, a second pad, a plurality of first power lines, a plurality of second power lines, and a plurality of control units is provided. The first pad is disposed on the first side of the device substrate. The second pad is disposed on the second side of the device substrate. The second side is opposite the first side. The first power lines are electrically connected to the first pad. The second power lines are electrically connected to the second pad. The control unit is electrically connected to at least one of the first power line and the second power line. The first pad does not overlap the second pad in a first direction perpendicular to the first side or in a second direction perpendicular to the second side. A display panel is also provided. A tiled display is also provided.

The display device may include a display panel and a frame diposed on a rear surface of the display panel. The display device also includes a plurality of binders fixed to the rear surface of the display panel and disposed between the display panel and the frame, and a plurality of coupling members penetrating through the frame and coupled to the plurality of binders. Therefore, the flatness of the display panel attached to the plurality of binders may be improved by adjusting the locations of the frame and the plurality of binders. Also, the display panel and the frame may be easily attached and detached using the plurality of binders and the plurality of coupling members.

An inverter system for a drive train of a motor vehicle is disposed in a multi-part housing. The inverter system includes a control board which can be connected via control cable connections to control lines, DC link capacitors, power semiconductors, control units, and current transformers. The housing is formed with an electronics level, a power level and a connection level. The interior of the housing has a plurality of zones in which different conditions prevail with regard to temperature and/or EMC shielding.

Disclosed in the present specification is a display device using semiconductor light emitting element, the device comprising: a display module including semiconductor light emitting element; a frame on which a plurality of the display modules is arranged; a first connection member which fixes the display module onto the frame on a rear surface of the display module, and which provides planar fluidity; and a second connection member having a magnet provided on a side surface of the display module, and applying attractive force to adjacent the display module. Therefore, provided in the present specification is a display device having a structure that is improved to minimize the gap between respective display modules.
