P3.91 Rental LED Display for AV Companies, 500x1000mm 16kg Aluminium Touring Cabinet for Rental Fleet Hire

A rental company buys a screen once and earns from it for years, so the useful question is not whether a wall looks good on demo day. It is how much of the year the inventory can be booked, how predictable the specification is when a quote has to be issued in an hour, and how much risk the business carries if a client asks for something the fleet cannot cover. Those are commercial questions, and the answers come from a due-diligence process rather than from a brochure.

This page is an application-focused proposal for a P3.91 rental cabinet as a fleet building block, subject to your own evaluation and to project review per job. The hardware basis is a 500×1000×95 mm aluminium-magnesium alloy cabinet of 16 kg, with eight 250×250 mm modules in a 2×4 layout at 0.5 kg each, giving 128×256 pixels per cabinet (32,768 dots) at 3.91 mm pitch and 65,536 dots per square metre.

Utilisation is driven by four variables a buyer can actually interrogate. First, the range of jobs the format can be quoted for, which depends on pitch, cabinet geometry and the content distances your clients work at. Second, the handling cost per job, which depends on weight, packing and crew method. Third, the failure cost, which depends on how faults are diagnosed and repaired and on what spares you choose to hold. Fourth, the cost of change, which appears when a client's request falls outside the fleet's capability and inventory has to be cross-hired.

None of those variables is decided by a single datasheet line, and this page does not claim a particular utilisation outcome. It sets out the checks that let a rental business reach its own conclusion before committing capital.

For fleet purposes the specification should be read as a quoting tool. A 3.91 mm pitch with 128×256 pixels per cabinet means a proposed wall can be converted into a pixel count during a client call, using N×128 by M×256 for N columns and M courses. That arithmetic keeps proposals consistent across sales staff and reduces the risk of promising a resolution the content cannot use.

The supplied figures also include brightness ≥1500 cd/m², 16-bit grayscale at 1,024 levels per channel, 256-step brightness adjustment, viewing angle 120° horizontal and 120° vertical, frame frequency ≥60 fps and a refresh figure listed at 1920 Hz. A buyer should test any of these that a contract will depend on, and should treat the 7 m nearest viewing distance as a supplied recommendation for this configuration rather than a rule for every booking.

The cabinet weighs 16 kg and each module 0.5 kg. That is a statement about mass, and it is genuinely useful when a quote has to include handling, transport weight and venue restrictions. It is not a statement about crew size, access equipment or build speed, which depend on your method statement and the site.

Likewise, 500×1000 mm describes geometry and the arithmetic of a wall, not the mechanism that joins cabinets, the way data and power are distributed, or how the hardware behaves after repeated transport. Ask the factory for the interface details, the packing specification and the handling recommendations in writing, and test a sample under your own conditions before a volume order.

Rental fleets live or die on consistency: a wall built from cabinets bought in different quarters must look like one surface to a client's camera. This page makes no claim about how a supplier achieves that. It does suggest the questions: how are modules matched within and between batches, what calibration is performed before shipment and what record accompanies it, what tolerance applies to colour and brightness across a production run, and how a later repeat order can be matched to earlier stock.

Buyers who ask those questions in the quotation stage get a written answer they can hold a supplier to. Buyers who assume consistency discover the problem at the first mixed build.

How many spare parts a fleet should hold is a business decision tied to your service-level commitments, depot locations and how quickly you can reach a job. No ratio is offered here, because the right number depends on your contracts rather than on the cabinet.

What can be stated is that service strategy should be agreed before purchase: what is expected to be repairable in the field, what returns to a workshop, what documentation accompanies a fault, and what the factory will supply as spares. Ask also for the diagnostic method a technician would follow, and test it once with your own team.

Input is AC110–220V ±10% at 50/60Hz, with DC 5V output at 40A, 60A or 80A depending on the supply option. Maximum consumption of 1000 W/m² is the figure to quote for electrical planning; average consumption appears as either 250 W/m² or 300 W/m² in the source data, so confirm the configured value rather than publishing either as fixed.

Control compatibility deserves the same discipline. Confirm that the processor and media server your warehouse already stocks can drive the cabinet, that spare processing is available for peak weeks, and that crew training stays valid across the fleet. A single control ecosystem is usually cheaper to support than two, but that is a commercial judgement for your business.

CE, RoHS and FCC documentation is available as claimed certification and should be verified against the final shipment model and each destination market; no independent third-party validation is implied. Protection is IP54 front and IP43 rear, which is fine for indoor and covered work but is not a weatherproof class, so hire agreements should state the operating limits.

Operating range is −30°C to 50°C at 15%–85% humidity, MTBF is listed at 5,000 hours and lifespan at 100,000 hours. Treat those as supplied planning figures and build your own reliability data from service records. Minimum order quantity, pricing, delivery timing and service-period terms are not stated on this page; they are commercial terms to be agreed in the quotation.

Before committing, obtain written answers on: interface and mounting details, packing and transport specification, module and batch matching method, calibration records provided at shipment, recommended spares list and their availability, power schedule based on maximum consumption, control platform compatibility, documentation set for client files, and the acceptance test used at handover.

Send your job mix, typical wall sizes, control platform and the service commitments you make to clients, and we will respond with a specification-based proposal and a pixel map for your two most common wall shapes. Commercial terms, and whether this format fits your fleet, remain subject to your own evaluation and to negotiation.

Q1: Is this cabinet suitable as a single fleet standard? That depends on your job mix, client distances and content expectations, and it is a decision for your own evaluation. The supplied specification — 3.91 mm pitch, 128×256 per cabinet, 16 kg — gives you the inputs to compare it against the work you actually quote.

Q2: Does the 16 kg weight mean a two-person build? No. Weight is one input to a method statement, not a crew calculation. Crew size, access equipment and build sequence should follow your own risk assessment and the site conditions, not a figure from a datasheet.

Q3: How many spares should we hold? That is a commercial decision based on your service commitments and depot reach, so no ratio is suggested here. What should be settled at purchase is what the factory supplies as spares, how quickly, and what repair is expected in the field versus in a workshop.

Q4: Can we mix these cabinets with our existing LED stock? Only where pitch, geometry and control platform allow a single coherent wall. Mixing pitch within one surface is visible, and mixing control ecosystems raises support cost. Send your current specification and we will tell you whether a mixed build is workable.

Q5: Is the refresh rate suitable for camera work? Refresh is listed at 1920 Hz in the supplied setting information. Camera performance depends on shutter, frame rate and content motion as well as the screen, so test with the production's actual camera package and confirm the final configuration before quoting a filmed event.
