Specification guide
An outdoor led screen panel lives in weather, sun, and a structure that must carry weight and wind. This guide lists the fields to freeze before factories reply. It is a buyer checklist. It is not a structural approval and it does not confirm that a proposed model meets a local code.
Brightness headlines are easy to copy and hard to compare. Ask whether the nit figure is for the proposed model, at what white balance, and whether it is before or after calibration. A 5,500 nit claim and a 6,500 nit claim are not interchangeable until the test basis matches. Ingress protection should name IP digits for the assembly you are buying, not for a different cabinet in the same brochure.
Prepare a Comparable RFQ
Weather duty adds layers a lobby wall does not carry. Keep them explicit so a lower module price is not mistaken for a lower project cost. The public indoor video-display pages of manufacturers, including a Daktronics indoor display family page, are useful as a reminder of which questions a datasheet can answer. They are not this desk's products and they do not transfer any rating to your outdoor face.
Finished width and height, pixel pitch, and the cabinet grid. Ask for the weight per square meter and the mounting points. Wind and attachment design stay with the buyer's engineer. The factory drawing supplies the mass and the hole pattern. The working envelope includes rear service depth if a catwalk is planned.
Input voltage, frequency, and phase, with average and maximum rated power at the brightness you specified. Ambient temperature range and any derating above a stated degree C belong on the datasheet request. Noise level of fans or power supplies matters when the face is near a window or a queue.
Current datasheet, structural connection drawing, photometric or brightness test basis, and any UL, ETL, or FCC record that names this model. ISO 9001, when offered, should name the supplier site and scope. A factory acceptance test plan, including what is photographed before packing, should be a line of its own.
Standard cabinet grids reduce documentation when the opening matches 500 mm modules. An application-specific mask, a corner, or a service hatch is justified when the architecture demands it, and it should be priced as its own specification deviation. Consumables and a spare parts list for modules exposed to sun should be counted separately from the face price.
A second procurement situation: a roadside face of about 20 square meters is being quoted by two plants. One price is per cabinet EXW and omits the power supplies. The other is per square meter FOB and includes power but not the structure. The process is to rebuild both replies onto one bill of materials, one Incoterm, and one spare-module count. The outcome is a comparable sheet the buyer can award or reject. This desk does not pick the winner and does not treat either nit rating as verified.
See the price labels, the indoor service notes, and the procurement brief for the shared evidence table.
Drawings can be described in the note and sent after the desk replies. The form has no upload field. An optional budget should state currency and whether it is per square meter or for the whole order.
