Most LED display problems are fixed in minutes with a screwdriver and the spares box — because LEDs are the component least likely to fail. The killers, in order, are power supplies, water, connectors, and configuration. Below: a three-minute triage, a twelve-row diagnostic table to bookmark, and each failure explained with the bench evidence [...]
If you're asking how to become an LED screen distributor, the honest answer is: you don't need a warehouse on day one. You need two or three customers who will actually buy, roughly $3,000–8,000 for demo units, and the willingness to service what you sell. Everything else — territory, exclusivity, price tiers — gets [...]
A led display factory audit is four checks in sequence: desk verification of the business license and certificates, a live video walk of the production floor, a sample tested against the quoted BOM, and one day on site before any container order. Each gate costs less than the loss it prevents. Run all four [...]
Take your wall's width times its height, divide by one panel's area, round up. A 4.8×2.7m wall is 12.96m²; a 500×500mm panel covers 0.25m², so 51.84 rounds to 52 panels. That is the whole LED screen size calculator — and also, usually, the wrong number. No grid builds 52. The formulas are the easy [...]
An OEM LED display partnership means you sell screens built in our factory under your own brand, in your territory, with our name kept out of it. We build, test, certify and back the hardware — you sell, install and service it. This guide covers the economics, the OEM/ODM/white-label differences, the channel-conflict question, and [...]
A street light pole LED display is a dual-face advertising screen bolted onto light poles that already line every arterial road. Budget $1,800–3,500 per pole FOB, $2,800–5,500 landed and installed, and expect $150–400 gross monthly revenue per screen in most markets. This guide covers approval risk, per-pole economics, the engineering that decides year five, [...]
How many nits an LED screen needs depends on what its light is fighting. Indoors: 600–1,200 for lobbies and churches, 1,500–2,500 behind street-facing glass. Outdoors: 4,500–6,500 roadside, 5,500–7,000+ in direct sun. Buy 20–30% above the number, because every panel dims from day one — and anything else is a guess you pay for twice. [...]
A typical indoor LED video wall runs $650–1,000 per square meter, or $60–93 per square foot, for P3 panels FOB from a Chinese factory. The same wall, quoted turnkey by a US integrator, lands at $400–900 per square foot. Same panels, up to ten times apart. The difference is not the screen. It is [...]
An LED poster display is a 600×1800mm portable screen on wheels that shows your promotions at 1,500 nits — roughly three times brighter than an indoor LCD — and updates over Wi-Fi, USB or optional 4G cloud in minutes. Expect $700–1,100 FOB for a P2.5 unit. It replaces the printed A-board that goes stale [...]
Rule of thumb: minimum comfortable viewing distance in meters roughly equals pixel pitch in millimeters. P2.5 works from about 2.5 m, P3 from 3 m, P4 from 4 m. Closer than that, you see pixels. Farther away, finer pitch mostly buys a smaller number on your quote. Here is the p2.5 vs p3 [...]
A church LED wall for a 300-seat sanctuary should run $19,000–32,000 all-in at factory-direct pricing — not the $40,000–150,000 that shows up on most US integrator quotes. The panels inside both numbers are often the same hardware. What changes is how many hands touch the project between the factory floor and your stage wall, [...]
A standard 500mm five-face LED cube display costs $600–1,400 FOB Shenzhen, depending on pitch — the same style of unit retails at A$1,760–7,348 in Australia. Compact 320–400mm cubes run $400–700 factory-direct; custom builds past 800mm start at $1,800–4,000+. This guide breaks down what those numbers buy, the corner engineering that explains quote gaps, and when [...]
