high contrast P3.91 SMD1921 outdoor video wall led display screen
Product advantage:
1. LED lamps failure rate <0.0001;
we select super led tips with high brightness, broad viewing
angle(H140degree, V140degree), all the LEDs are ageing for 72 hours
before assembly;
2. Modules: we have 11 years for manufacturing led screens, both
price and quality advantages;
We use 1R1G1B pixel configuration to realise high
brightness.Modules would be aging for 72 hours, after assembly into
a screen, still aging 72 hours. so the final LEDs are aging at
least for 216 hours, up to 9 days.
3. Cabinets: Aluminum/ Iron, quick to assemble and disassemble and
waterprrof well.
4. Screen: use state-of-the-art LED drive IC-MBI5026/MBI5124,
brightness can up to 8000cd/m2, live color video and vivid image
with 256 grey level.
For outdoor led displays, all of them are IP 65 and designed to
withstand harsh environmental conditions, such as sun glare, heat,
cold, and humidity. You can see more details in the quotation.
5.Packing: Anti-shaking wooden case, which is lighter than normal
wooden case but more protective to the goods. Flight case with
wheel which is more convenient .
6. Spare parts for free: Our screen's scotoma rate is below 0.0002,
but to prevent accidental, we provide some free spare parts
according to the size of screen.
7. Warranty for 24 months: During the guarantee period, we will
send new lights with new order for small quantity. For defective
batch products, we will repair them and resend them to you or we
can discuss the solution according to situations.
8. Technology support: we have full hardware and software files
available for all you need, we are always here to service on you.
