The RLG-AT series is a screen terminal for networked content publishing, built two-faced: 1920×1080 on each side, with the A and B faces running identical or independent content — and, depending on configuration, at different brightness per face. Standard brightness is 450 cd/m² with 350 and 700 cd/m² factory options; contrast is 1200:1 (43″) or 1300:1 (55″), viewing angle 178°/178°. A quad-core RK3288 Android 5.1 system (Windows/i3/i5/i7 optional) plays from HDMI, LAN, Wi-Fi, USB or TF card; content is published remotely from PC, tablet or phone with cloud management and real-time material monitoring, and playlists support full-screen and 2/3/multi-zone split layouts mixing image and video. The 2 cm-thin body hangs from the ceiling, stands on the floor, mounts on a wall or sits upright — the mounting style is coded in the model suffix (B/D/L/T).

Is this the right display for your project?

Plain-language guide — based only on what this product actually does.

Street-facing shop windowsHang one unit in the glass: the outward face works passers-by while the inward face sells to customers already inside — two campaigns, one device, no window space lost to a screen back.

Jewelry & premium retailThe 2 cm profile hangs beside showcases without crowding them; per-face brightness plans let the window side run brighter than the counter side.

Airports & transit retailFleets of hung units along concourses publish from one cloud console — split-screen playlists mix flight-side promos and brand content, with real-time monitoring of what each face is playing.

Not the right pick if you need…

Glass that catches direct sunlight most of the day — specify the 700 cd/m² build, or consider an outdoor-rated signage unit instead
Single-face wall or totem advertising — the Indoor Digital Signage line does that for less
A display you can see through (transparent showcase glass) — that is a different product family; describe your cabinet and we will advise

Engineering note: Face brightness is fixed at production — 350, 450 or 700 cd/m² — not switchable on site, so match it to the glass: shaded arcades do fine at 450, sun-touched frontages should specify 700. Confirm the mounting suffix (B/D/L/T) against your shopfitting plan before ordering, and note the operating humidity rating is 65%.

Double-Sided Window Display FAQ — RLG-430 / RLG-550

Can each side show different content?

Yes. The unit has two Full HD 1920×1080 faces that can play either the same loop or two different playlists — one aimed at the street, one at shoppers inside. Both 43″ (RLG-430) and 55″ (RLG-550) sizes work this way, with 178°/178° viewing angles per face.

Is it bright enough for a sun-facing shop window?

Standard brightness is 450 cd/m² with 1200:1 contrast and 92% color saturation. For windows that catch direct daylight you can order the 700 cd/m² option; for dimmer interiors a 350 cd/m² version is also available. Choose the brightness at order time — it is a factory option.

How do I update the content remotely across several shops?

The built-in Android 5.1 player (quad-core RK3288, 2 GB RAM, 8 GB storage) supports cloud publishing over the RJ45 10/100M port or Wi-Fi, and an optional 3G/4G module covers sites without fixed internet. You can also load media locally via 2× USB 2.0 or a TF card up to 64 GB.

What are the installation options?

Four mounting codes cover the usual retail cases: wall-mount (B), ceiling-hung (D), upright (L) and floor-standing (T). The hanging body is only 2 cm thin, so a ceiling-hung unit floats in the window without blocking the view. Pick the mounting code when ordering.

How much power does it use and what supply does it need?

Maximum draw is ≤80 W per unit on a wide-range AC 100–240 V, 50/60 Hz input, so it runs on 110 V and 220 V grids alike. The operating range is 0–60 °C, which tolerates heat build-up behind glass in a sunny window. Response time is 6 ms.

Can I get more memory, storage or a Windows version?

Yes, several factory options exist: RAM upgrades from 2 GB to 4 GB, storage from 8 GB to 16 or 32 GB, and the Android 5.1 platform can be replaced by Windows with i3/i5/i7 processors. There is also one HDMI input if you prefer to feed content from an external player.
