Led Video Wall Sourcing - Factory sourcing support for led video wall

led video wall

A led video wall brief has to name the room, the viewing distance, and the cabinet geometry before a factory number means anything. Led Video Wall Sourcing records those open items and sends the same sheet to more than one plant. The desk does not assemble modules and does not publish a warehouse count.

Configuration Pixel pitch, cabinet size in millimeters, and whether the wall is fixed or rental.

Quantity Cabinet count or square meters, plus spare module percentage still marked unknown if you have not chosen it.

Destination US city, receiving dock limits, and the Incoterm you want quoted.

Files Elevation, power single-line, and the control diagram if one exists.

What a first quotation may include, exclude, or leave open

Use this ledger to stop a headline cabinet price from hiding flight cases, spare power supplies, or on-site commissioning. Nothing below is a published rate.

Ask to include

Cabinets or panels named by the proposed model
Receiving cards and power supplies listed on the bill of materials
The control interface the supplier says is required for that model
Export packing described for the stated quantity

Treat as excluded until written

Steel structure, trim, and architectural cladding
Front-service tools that are sold as a separate kit
Content players, fiber converters, and venue processors
Union labor, lift rental, and local electrical permits

Still pending

Brightness in nits and the test pattern used
Indoor or outdoor ingress protection for the exact cabinet
Refresh rate at the gray scale you care about
Delivered cost after freight, duties, and spares

Four desks share one handoff

Procurement, engineering, operations, and quality do not need four different walls. They need four question lists that meet on the same model number.

Procurement

Lock quantity, currency, Incoterm, and the US destination. Ask whether spare modules are priced per cabinet or as a whole-order kit. A target budget stays optional and is not a confirmed factory figure.

Engineering

Match pixel pitch to the closest viewer, not to a brochure photograph. Record input voltage, phase, and the control interface. A specification deviation belongs in a column next to the requirement, not in a footnote that never gets compared.

Operations

Mark service access as front, rear, or both, and the clearance in millimeters. Note ambient temperature and whether the wall runs all day or only for events. Throughput here means how fast a failed module can be swapped, not a production-line rate.

Quality

Request a factory acceptance test tied to the proposed cabinets, plus the certificate scope if a UL, ETL, or FCC file is offered. A family datasheet does not transfer those marks to another pitch.

Write the open fields with units before anyone compares sheets: refresh at 1920 Hz or 3840 Hz, an indoor screening band of 600 to 800 nits, an outdoor screening band of 4500 to 5500 nits, IP54 versus IP65, and seam repeatability of 0.1 mm only if the drawing names that tolerance. Rated power belongs in watts per cabinet at a stated nit level, for example 180 W or 450 W. Duty cycle belongs in hours on, for example 14 hours on and 10 hours dark. Noise level, if the room is a studio, is a decibel question, often checked near 25 dB or 40 dB at 1 m. Commissioning scope might be 2 days or 5 days and must say who attends. A spare parts list of 5 percent or 8 percent of modules is a buyer choice, not a default. Preventive maintenance at 6 months or 12 months stays on the supplier sheet. A 2.6 mm pitch and a 3.9 mm pitch are different questions, as are a 500 mm cabinet and a 1000 mm cabinet.

Power, signal, and cabinet questions

Which input voltage should the quotation repeat?

Write the site voltage, frequency, and phase, such as 120/208 V, 60 Hz, three phase, if that is what the room actually has. Ask the supplier to restate the utilities requirement for the exact proposed power supplies. A 100-240 V label on a family sheet is a question, not proof that your panel string is compatible.

How should brightness be compared?

Ask for nits, the white-point or test pattern, and whether the figure is calibrated or peak. Outdoor and indoor numbers are not interchangeable. If the test basis is missing, leave the cell blank instead of copying a catalog peak.

What does pixel pitch fail to tell you?

Pitch describes diode spacing. It does not set viewing distance by itself, and it does not set the working envelope of the steel. Pair pitch with cabinet millimeters, seam tolerance, and the closest seat.

When is a receiving card part of the wall?

Only when the quotation names the card, the backup path, and who supplies the processor. A control interface mentioned in marketing copy can be an accessory line. Put it in the included column or the excluded column before you compare totals.

Can spare modules be assumed at a fixed ratio?

No ratio is stored here. State the spare count you want, or mark it unknown. Consumables such as masks, magnets, and data cables should be listed separately from the spare LED modules.
