Factory sourcing support for led video wall
Procurement workflow
An outdoor led video wall decision fails when sun, rain, and service height are added after the indoor pitch has already been copied. This workflow keeps weather, structure, and evidence on the sheet before a plant is asked to price the face.
Every cell is a question for the supplier of the exact model. A public product-family page can suggest the shape of the question. It does not fill the cell.
| Topic | What to ask | Who answers |
|---|---|---|
| Pixel pitch and brightness | Pitch in millimeters, nits, test pattern, and whether the figure is maintained or peak | Proposed supplier, on the model datasheet |
| Weather | Ingress protection, operating ambient temperature, and any coating or mask note | Proposed supplier, model-specific |
| Power | Input voltage, frequency, phase, redundancy, and wattage basis | Proposed supplier, then buyer electrical review |
| Structure | Cabinet weight, hanging or pedestal interface, and service access | Supplier data plus the buyer's structural engineer |
| Control | Receiving cards, processor, and backup path in or out of the quotation | Supplier bill of materials |
| Acceptance | Factory acceptance test scope and which certificates, if any, name this model | Supplier quality file, reviewed by the buyer |
Standard cabinets reduce documentation when the face is rectangular and the brightness target is modest. An application-specific mask, curve, or high-nit requirement adds lines. Choose the path by writing the constraint, not by calling one path advanced.
Only as a screening hint. The quotation must restate nits for the proposed cabinets and the test basis. Headline rating versus stated test basis is the dispute to keep visible: a peak number can win a slide and still lose the sunny hour you care about.
Overall face size, cabinet module map, power entry, and the service side. Ask for clouds where the offered depth conflicts with the structure. Do not treat a rendered night photo as a drawing.
One row per clause: your requirement, the offer, and whether the gap is accepted, rejected, or still open. A specification deviation buried in an email will not survive the next revision of the price sheet.
Quantity, currency, Incoterm, freight responsibility, spare modules, and commissioning days. Delivered cost is those lines together. A lower cabinet figure with the lift, the cases, and the spares excluded is a different purchase.
Close the outdoor sheet with numbers the supplier must restate: control interface by processor name, working envelope with 800 mm lift clearance or a catwalk width, duty cycle as night hours, throughput only if a crew rate is real, rated power in watts at the nit figure, noise level if the face is near a residence, commissioning scope of 2 days or 5 days, consumables, a spare parts list, preventive maintenance at 6 months or 12 months, and repeatability of the mask seam if the drawing gives 0.1 mm. A standard rectangular face can stay on a catalog cabinet. A curve, a high-nit mask, or a 20 m viewing throw is the application-specific path. Lowest cabinet price versus comparable lifecycle scope is the commercial dispute: spares, freight, and lift time change delivered cost after the unit column is aligned.
Cross-check equipment names, price scope, and the procurement brief before you send the outdoor sheet.
Describe the face, the files you hold, and the items still unknown. No file upload is attached to this form. Put pixel pitch, brightness target, ingress questions, quantity, destination, and lead time in the requirement text.
