How Should an LED Display Factory Acceptance Test Be Specified?

Quick answer

Specify the factory acceptance test as a written method attached to the purchase order, not as a verbal promise to test the wall. The method should name the exact model and pitch being supplied, state the content that will be shown, state how defects are recorded and how cabinets are identified, and state what evidence the supplier must provide. Planar Komodo Series is offered as Komodo 0.7, Komodo 0.9 and Komodo 1.2, with the specification table listing pixel pitches of 0.75mm, 0.9375mm and 1.25mm for those models, so a test written against a family name rather than a named model can end up checking the wrong product. Ask the supplier to confirm the test scope in writing before production starts, and make acceptance a comparison against that agreed method. (planar-komodo-series-brochure-3-2026)

Anchor the test to the exact model, not the series name

A factory acceptance test is only meaningful if it is written against the product you are actually buying. Planar Komodo Series is offered as Komodo 0.7, Komodo 0.9 and Komodo 1.2, and the specification table lists pixel pitches of 0.75mm, 0.9375mm and 1.25mm for those models. A test plan that says only Komodo Series does not tell the factory which pitch, cabinet resolution or module to assemble and check. (planar-komodo-series-brochure-3-2026)

The same principle applies across a range. Planar Cobra Series is listed as Cobra 0.6, Cobra 0.7, Cobra 0.9 and Cobra 1.2, and Planar describes each as a named model with its own pixel pitch. Ask each bidder to write the exact model name and pitch on the acceptance test line of the order, and to confirm that the test will be performed on that model rather than on a similar unit from the same family. (Planar Cobra Series | Planar)

Model-specific drawings underline why this matters. The Komodo 0.7 module overview drawing shows a module with 9X attachment magnet. That is a drawing for one named model, so treat module-level fit and handling as model-specific and ask for the drawing that belongs to your ordered model when you write the test. (komodo-07-outline-rev_c-1)

Agree the content that will be shown during the test

A factory acceptance test that runs only a supplier demo pattern tells you very little about your wall. Ask the supplier to run your own content during the test, including the material that places the greatest demand on the display, and record in the order which files or sources will be used. Planar describes the Komodo Series as intended for the most visually discerning indoor applications, so the test should reflect the intended indoor use rather than a generic loop. (Planar Komodo Series | Planar)

Content also determines which performance claims you can reasonably check. Planar Komodo Series is described as delivering superior color uniformity and wide viewing angles, and the brochure states a DCI-P3 color gamut at 95% or above for color accuracy. If those properties matter to your project, ask the supplier to include content that lets you look at uniformity across the wall and colour at the angles people will actually view from, and write that into the test method. (planar-komodo-series-brochure-3-2026)

Where the wall will carry high frame-rate sources, say so in the test scope. The Planar Komodo Series brochure states that the series supports high frame-rate sources up to 120Hz. Ask the supplier to confirm in writing whether your ordered model is being tested with the source types and frame rates you intend to use, so the test covers the signal path as well as the panel. (planar-komodo-series-brochure-3-2026)

Record defects and cabinet identities in a way you can act on

Agree before the test how a defect will be recorded: what counts as a defect, who logs it, where the position is noted on the wall map, and what photographic or written record accompanies it. Ask for the record to identify the cabinet and module position rather than describing a fault as somewhere in the middle of the wall. Planar Komodo Series drawings use defined sheet titles such as KOMODO 0.7 MODULE OVERVIEW and KOMODO 0.7 8X6 MOUNT LAYOUT, which shows the level of positional reference a supplier can work to when identifying parts. (komodo-07-outline-rev_c-1)

Cabinet identities should be settled in the same document. Ask the supplier to confirm how cabinets and modules are labelled and serialised, and require that the labels on the shipped units match the cabinet map used during the test. Keep the cabinet map and the test record together so that a defect logged at the factory can be traced to a specific unit after delivery. (komodo-07-outline-rev_c-1)

Where the wall uses a controller and switch, include them in the identity record. The Planar Komodo Series brochure lists a Megapixel HELIOS controller and a Megapixel HELIOS switch alongside the display, with the switch described as having 12 x 1Gb/2.5Gb Ethernet video output ports. Ask the supplier to state which controller and switch are in scope for the test and how they are identified in the handover record. (planar-komodo-series-brochure-3-2026)

State the acceptance evidence the supplier must hand over

Decide in advance what counts as evidence that the test happened and what the result was. Ask for a signed test record naming the exact model, the content shown, the positions checked, the defects found and their disposition, and the identity of the person who performed the test. Planar states that information on its product pages is subject to change without notice, so the acceptance record should capture the configuration actually tested rather than relying on a brochure. (Planar Cobra Series | Planar)

Ask for the documents that support the configuration. The Planar Komodo Series specification table lists certifications including NRTL UL 62368-1, TUV Rheinland, FCC Class A, CE EN62368-1, EN 55032 Class A and EN55035, WEEE, and CISPR 32/2015 for that series, and lists a 3 Years warranty. Treat those as named-series entries and ask the supplier to state which certificates and warranty terms apply to your ordered model, with copies supplied as part of the handover. (planar-komodo-series-brochure-3-2026)

Include the operating and storage conditions the supplier is committing to, so the test record can be read against them. The Planar Komodo Series specification table lists an operating range of 0°C to 40°C, 32° to 104° F, up to maximum operating temperature, 10-80% relative humidity, non-condensing, and a storage range of -10° to 60° C, 14° to 140° F, at 10-85% relative humidity, non-condensing. Ask the supplier to confirm the equivalent figures for your ordered model in writing. (planar-komodo-series-brochure-3-2026)

Make the test a condition of the order, not a favour

Write the factory acceptance test into the purchase order as a defined stage with a defined output. State that the test method, the content list, the defect record format and the handover evidence are agreed before production, and that shipment follows a completed and signed test record. This turns acceptance into a comparison against your written method rather than a debate after the wall arrives. (planar-komodo-series-brochure-3-2026)

Keep the test scope proportionate to the product. Planar describes the Komodo Series as a premium indoor fine pitch LED video wall range featuring COB MicroLED technology, and describes the Cobra Series models as ultra-fine or fine pixel pitch LED video walls engineered for demanding visual environments. A test written for a fine-pitch indoor wall should reflect that intended use, and the supplier should confirm in writing which checks apply to the model you ordered. (Planar Komodo Series | Planar)

Finally, agree what happens if the test finds defects. Ask the supplier to state in writing how a defect is dispositioned, whether the unit is reworked or replaced, and how the reworked unit is re-tested before shipment. Put that remedy in the order so the factory acceptance test has a defined outcome rather than ending in an unresolved list. (komodo-07-outline-rev_c-1)

Factory acceptance test decisions and the evidence to request

Frequently asked questions

Can the factory acceptance test be described as testing the series rather than a named model?

No. Planar Komodo Series is offered as Komodo 0.7, Komodo 0.9 and Komodo 1.2, and the specification table lists pixel pitches of 0.75mm, 0.9375mm and 1.25mm for those models, so a test written against the series does not identify which product is being checked. Write the exact model name and pitch into the test line of the order. (planar-komodo-series-brochure-3-2026)

Should the test include the controller and switch as well as the display?

If they are part of your order, include them in the identity record. The Planar Komodo Series brochure lists a Megapixel HELIOS controller and a Megapixel HELIOS switch alongside the display, with the switch described as having 12 x 1Gb/2.5Gb Ethernet video output ports. Ask the supplier to state which controller and switch are in scope for the test and how they are identified in the handover record. (planar-komodo-series-brochure-3-2026)

What should happen if the factory acceptance test finds defects?

Agree the remedy in writing before the test. Ask the supplier to state how a defect is dispositioned, whether the unit is reworked or replaced, and how the reworked unit is re-tested before shipment. Planar Komodo Series drawings use defined sheet titles such as KOMODO 0.7 MODULE OVERVIEW and KOMODO 0.7 8X6 MOUNT LAYOUT, which shows the level of positional reference a supplier can work to when identifying the affected part.
