Double-sided indoor LED poster 640×1920 mm
One cabinet, two screens: the double-sided LED poster has an independent 640 × 1920 mm screen on each face, so people see it from both sides of a walkway, lobby or store floor. The die-cast cabinet has front service, the LEDs are GOB-coated and a stand is included. Six pitches from P1.25 to P3.076 give 208 × 624 to 512 × 1536 pixels on each face, with brightness from 500 nit. Assembled at our Shenzhen assembly factory, shipped EXW / FOB Shenzhen.

What is a double-sided LED poster?
A double-sided LED poster has two screens back to back in one cabinet, each 640 × 1920 mm and each with its own resolution, so a single poster serves two directions of foot traffic. It is the answer to a poster standing in the middle of a passage where a single-face poster would show its back to half the audience. Some buyers call this format a double-sided pylon; it is direct-view LED, not an LCD kiosk.
What is different about this cabinet
Two independent screens. Each face is its own screen, for example 256 × 768 pixels per face at P2.5. Content is prepared and loaded for each face.
The die-cast principle. Magnetic modules come out from the front with a suction cup, with no rear cover to open. Die-cast aluminum, with GOB over the LEDs.
Stand included. The poster ships with its stand.
Stands alone. The two faces are one finished unit; a double-sided poster does not daisy-chain with other posters. For a wall made of posters use the die-cast LED poster, 640 mm.
Resolution and pitch: choose the picture quality
Every poster in the range has the same screen size: 640 × 1920 mm, 960 × 1920 mm or 1280 × 1920 mm. What changes with the pixel pitch is how many pixels fill that size. At P2.5 a 640 × 1920 mm poster shows 256 × 768 pixels; at P1.25 the same poster shows 512 × 1536 pixels, four times as many. More pixels give sharper text, cleaner edges and let viewers stand closer. The cabinet decides how you service and move the poster. The pitch decides how the picture looks. On a double-sided poster the resolution below is for each face.
| Pitch | LED | Resolution (per face, 640 × 1920 mm) | Pixels in total | Viewing distance |
|---|---|---|---|---|
| P1.25 | SMD1010 | 512 × 1536 | 786,432 | from 1 m |
| P1.538 | SMD1212 | 416 × 1248 | 519,168 | from 1.5 m |
| P1.86 | SMD1515 | 344 × 1032 | 355,008 | from 2 m |
| P2 | SMD1515 | 320 × 960 | 307,200 | from 2 m |
| P2.5 | SMD2121 | 256 × 768 | 196,608 | from 3 m |
| P3.076 | SMD2121 | 208 × 624 | 129,792 | from 3 m |
The poster is not chained, so there is no joined-screen size: it is two faces of 640 × 1920 mm each. At the same pitch the resolution equals the single-face die-cast 640. Choose the pitch from the nearest viewer on either side: for 2 to 3 m P1.86 to P2.5, for closer reading P1.538.
Where it is used
Shopping centers and malls. A freestanding poster in the middle of a walkway, readable from both directions; P2.5 (256 × 768 px) for viewers from 2.5 m.
Hotel lobbies and conference foyers. Program and wayfinding for people arriving from either side.
Airports, stations and waiting halls (indoor). Information visible from both sides of a passage.
Showrooms and restaurants. A menu or promotion that works from either side of the aisle.
Exhibitions. One poster serving two stand aisles.
Control and options
- NovaStar control + Mean Well power supplies: the default set.
- Huidu or Colorlight control: a lower-cost option.
Receiving cards and controller are matched to one brand, so name your system when you ask for a quote. Content loads over Wi-Fi, LAN or USB (4G Optional), and the poster then plays on its own, with no computer connected.
Optional: alternative LED brands; built-in speaker; hanging rings; 4G module; flight case (double-sided case); wooden crate; OEM logo, labels, packaging and documents. Power supply can be changed (Optional).
Daisy chain
Not available on this poster. Each double-sided poster is a finished unit with two independent screens. To build one large wall from several posters, use the die-cast LED poster, 640 mm and chain it.
Packaging and shipping
A double-sided poster ships in a standard cardboard box with foam inserts (included in the base price); the stand is packed separately. A flight case for a double-sided poster and a wooden crate are Optional. The packing list for your order states the weight and size of every piece. See packaging and shipping. We sell EXW / FOB Shenzhen.

Questions about this poster
Can the two sides show different content?
Yes. The two faces are independent screens, so each face can show its own content.
Do I need a mirrored version of my artwork for the second face?
Each face is an independent screen, so prepare the artwork for each face the way you would for a single-face poster.
Which pixel pitch suits people walking past at 2 to 3 meters?
Work from the nearest viewer: the minimum viewing distance in meters is roughly the pitch in millimeters. For people passing at 2 to 3 m, P2 or P2.5 is the usual choice (320 × 960 or 256 × 768 pixels per face); from 1.5 m look at P1.538 or P1.86. Both faces have the same pitch.
Is it two posters glued together?
It is one cabinet with two screens on one stand, supplied as one unit.
Can I put two of them side by side?
You can stand them next to each other, but they do not daisy-chain into one picture. To show one picture across several posters, use a chain of die-cast 640 posters.
What resolution does each face have?
The same as a single-face 640 × 1920 mm poster of that pitch: 256 × 768 pixels at P2.5, 344 × 1032 at P1.86, 512 × 1536 at P1.25.
Is the second face as bright as the first?
Both faces use the same modules and the same pitch, with brightness from 500 nit.
How do I change a module?
From the front, with a suction cup, as on the die-cast 640.
How much power does it use?
At P2.5 the poster uses up to 400 W/m² at maximum and about 135 W/m² on average, counted on the screen area you run. Power depends on the pitch and the content, and the quotation gives the figures for your configuration. Power supply can be changed (Optional).
Where do people usually put it?
In walkways and lobbies where people pass on both sides. Where only one side is seen, the single-face die-cast LED poster, 640 mm is the simpler choice.
