Double-Sided Outdoor LED Billboards: Layout & Scope

Tim Teknik DOIT VISION

A double-sided billboard needs two face schedules and one schedule for shared equipment. Give each face a name tied to a site direction. “East face” and “west face” stay clear on drawings, media playlists and spare-part orders even when the cabinets are identical.

Count the cabinets on each face

Untuk standar Square 960 layout five cabinets wide by three high, each face measures 4.80 × 2.88 m. The example uses back-to-back display faces; the space and structure between them are separate design dimensions.

Jumlah Satu wajah Two identical faces
Kabinet 15 30
Area aktif 13.824 m² 27.648 m²
Dimensi aktif 4.80 × 2.88 m Two faces, each 4.80 × 2.88 m

A supplier quoting 13.824 m² and one quoting 27.648 m² may be pricing different quantities for the same site. Check the face schedule before comparing unit prices.

Decide whether the faces run together

If both directions show the same campaign, specify whether schedules and brightness changes should also match. For separate advertisers, request independent content routing and schedules. Have the controls supplier label outputs by face and demonstrate that replacing one playlist leaves the other unchanged.

Resolve the space between the backs

Show both cabinets in section, including frame members, cable entry, drainage and the route for heat to leave the assembly. Confirm which face gives access to power supplies and receiving cards. A module that comes out forwards does not by itself make the space between the faces serviceable.

Opposite faces may have different exposure. For example, only one side may need the standard Square high-brightness option. Identify that face and its corresponding electrical load; do not average two different builds into a single cabinet specification.

Price repeated items separately from shared work

List cabinets, modules and face-specific distribution by face. List any shared support, controller, network connection or site mobilisation once, with its coverage stated. Leave enough detail for the installer to identify what happens to the working face when the other is isolated for maintenance.

FAQ (Pertanyaan Umum)
Is a double-sided billboard one cabinet or two display faces?
Describe the intended assembly on the drawing. The example uses two faces made from standard Square cabinets, mounted back to back on a project-specific support. A request for fifteen cabinets can therefore mean fifteen per side or fifteen in total. Give a separate grid for each face and identify any shared enclosure explicitly.
Can both sides show different content?
Yes, provided independent playback and signal routing are specified for the ordered system. Name the two outputs by site direction, identify who manages the playlists and say whether the faces need different operating schedules. Include a commissioning check that changes content on just one face while the opposite face continues its scheduled playback.
Is the quoted area per face or for both faces?
The quotation should state both. For the five-by-three example, the visible area on each side is 13.824 square metres and the combined equipment area is 27.648 square metres. Dimensions for the structure, cladding or advertising permit may use another boundary. Keep those dimensions separate from the active LED area on the purchase order.
Can a double-sided screen be serviced without a rear corridor?
It depends on how every replaceable part and connection can be reached. Ask for the service section showing module removal, control-box access and cable disconnection on both sides. If an internal part needs access between the faces, resolve that route before the structure is released, rather than assuming front-removable modules solve it.
Does sharing a frame reduce power consumption?
Sharing a frame changes the mechanical arrangement. Screen power still depends on what is installed and how each face operates. Size the supply against the selected equipment and its simultaneous operating assumptions. For an energy estimate, model the schedule and brightness of each face separately, then add any shared equipment once.
Is the price twice that of a single-sided billboard?
Cabinets and other face-specific items can be counted twice for identical faces. Structure, control, freight and installation may be shared, separate or partly shared, depending on the design. Compare quotations line by line against the same face schedules. Simply doubling a single-face price can both miss a second system and double-count shared work.
