48 Inch Commercial Ultra-wide Android Screen: RFQ Preparation Guide for Project Buyers

A single line on a purchase order — "48 inch ultra-wide Android screen, 20 units" — is usually where a project quotation starts to drift. The factory reads that as one thing, the integrator's drawing means another, and the sample that arrives does not fit the shelf. For stretched-format hardware such as the 48 Inch Commercial Ultra-wide Android Screen, the difference between a clean project run and three rounds of revisions is almost entirely what was written down before the request for quotation was sent.

This guide walks through the specifications, drawings, and commercial terms a project buyer should have ready before contacting a commercial display manufacturer, using the 48-inch ultra-wide format as the running example.

Before the RFQ: Fix the Physical Constraints

In a stretched display program, mechanical fit is the first risk, not image quality. Ultra-wide panels are long and shallow, so enclosure depth, shelf load, and cable routing decide whether the unit can be installed at all. Confirm these items on your own drawings first:

• The finished opening or shelf depth where the display will sit, including clearance for connectors and power cabling at the rear.
• How the unit is supported: shelf-mounted, free-standing, or a custom bracket. The 48-inch model is documented as supporting shelf-mounted, free-standing, and other installation methods.
• Where power enters and how far the run is, since power delivery changes once the unit is fixed in a fixture.
• Ambient conditions at the site. The documented operating range for this model is -20 to 60°C with 5% to 90% humidity, and cooling is fanless — relevant if the fixture is enclosed or near a heat source.

Getting these three or four numbers into the RFQ as a small table, rather than prose, is what lets a factory return a workable proposal on the first pass.

Reading the Panel Specification Without Over-Specifying

Ultra-wide formats have resolutions that do not map onto ordinary TV standards, and buyers frequently assume a number that does not apply. Documented for the 48-inch unit: an IPS LCD panel at 3840 × 720, brightness of 1000 cd/m², and a 1000:1 contrast ratio. Compare that against the wider family, and the practical point becomes clear — brightness and pixel layout vary across formats, so specification comparisons between sizes are not interchangeable.

Two cautions worth noting when you write the panel requirement into a purchase specification:

• Aspect ratio on a datasheet can be listed in a way that does not match the physical shape of a stretched panel. Ask the supplier to confirm the active area in millimetres and match it to your fixture drawing. The pixel count matters less for fit than the active area does.
• Brightness alone does not tell you whether content is readable in a given store. Ambient light at the exact mounting position, not the showroom, sets the requirement. State the mounting environment in the RFQ and ask the factory to advise.

Platform and Content Management: The Items Buyers Forget

For an Android signage display, the board specification drives app behaviour long after installation. The 48-inch model is built on a Rockchip RK3288 quad-core processor with 2GB RAM and 8GB internal storage, with integrated WiFi (2.4G, 802.11 b/g/n), Bluetooth 4.0, and an RJ45 network port. I/O is documented as a TF card slot, DC jack, and two USB host ports.

Before you submit the RFQ, settle internally what your content workflow actually needs:

• Who publishes the content and from where — local USB stick, local network, or remote management across sites. Remote publishing changes the network requirement and should be stated up front.
• Which apps need to run, and whether a custom Android image or kiosk-mode boot is required. Custom images and branding fall under OEM / ODM work and should be flagged in the RFQ rather than discovered at sample stage.
• Whether peripherals — a touchscreen layer, a beacon, a camera — must be enabled. Touch and add-on hardware affect both the driver build and the enclosure.

If you are running a mixed fleet, also note that ZCDISPLAY offers separate Android mini PCs, including the RK3288 industrial media player with dual LVDS and HDMI output, VESA or DIN-rail mounting, and a fanless aluminium body. Some projects are served better by a standard panel plus a discrete player than by an integrated Android screen. Deciding that before the RFQ prevents two incompatible quotations.

Commercial Terms to Specify, Not Assume

Pricing, minimum order quantity, lead time, warranty terms, and certification scope are not interchangeable between projects, and none of them should be quoted back to a client as a fixed figure until the supplier confirms them for your quantity and configuration. Put your real constraints into the request instead:

Item to supply in the RFQ	Why it changes the quotation
Total quantity plus the split by site or by phase	Phased rollout and single-shipment pricing differ; the factory needs the schedule to price it.
Target delivery date and installation window	Sample approval and production sit inside that window; missing it is the usual cause of rushed freight charges.
Destination and Incoterms basis	Ultra-wide cartons are long and awkward; freight cost depends on how they are shipped.
Certification or documentation your market requires	Compliance scope must be confirmed against the exact model and configuration before it is promised downstream.
Branding, enclosure colour, or custom housing needs	Customising the housing is engineering work, not a line-item option, and is priced separately.

For a distributor sourcing across a range of sizes, it is worth pricing the adjacent formats in the same enquiry. The ultra-wide line spans from compact bar formats to large runs — 19, 24, 28.6, 37, 42, 48, 48.5, 49.5, 58.4, 86 and 88 inch models are all listed on the site — so one enquiry covering the sizes you actually resell gives you a comparable set of numbers.

Sample and Acceptance: Write the Test Before You Order

A sample that looks good in a office is not an accepted sample. Before the first unit ships for evaluation, define in writing what passes:

• Fit test against the real fixture or shelf, at the real site, with the real cable route.
• Content test using the artwork you will actually run at full panel width, not a generic demo loop.
• Readability check at the installation position during the store's busiest lighting conditions.
• Publishing test end to end, from the person who creates the content to the screen on the floor.

Send that acceptance list to the supplier with the sample request. Both sides then know what "approved" means, and a production run does not start against an undefined standard.

A Short RFQ Checklist

• Model and size, with active area confirmed in millimetres against your fixture drawing.
• Mounting method and ambient conditions at the site.
• Resolution, brightness, and panel type confirmed against the product page, not assumed from a similar size.
• Platform: integrated Android or panel plus external player, with RAM, storage, and connectivity stated.
• Content workflow, kiosk mode, and any custom Android image or peripheral.
• Quantity, phasing, delivery date, destination, and Incoterms basis.
• Documentation, branding, and enclosure requirements flagged as engineering scope.
• Written sample acceptance criteria attached to the sample request.

ZCDISPLAY supplies these displays factory-direct for wholesale, distribution, and project integration, with engineering support from prototyping through production and quality control. If you are preparing a quotation for a store rollout or a fixture programme, the contact form is the fastest route to a specification check against your drawings — send the mounting details and quantities above, and you will spend fewer cycles on samples that were never going to fit.
