Overview

A 55-inch screen that keeps the view behind it

The LG 55EW5P-M is a transparent OLED display built for places where a solid screen would block the view. With 43% transparency, the panel shows content while people, products and interiors remain visible behind it. It is a practical choice for a shop window, a hotel lobby or a showroom where the display should add to the space rather than close it off.

Specifications that shape the purchase

Buyers comparing this model with conventional signage should look first at the panel and the environment rating. The key figures are listed below.

Panel: 55-inch OLED, 16:9, native 1920x1080 (FHD), 120Hz refresh rate
Brightness: 200/600 nit (APL 100%/25%, without glass)
Contrast ratio: 200,000:1, with 10-bit colour depth
Protection glass: 3.0mm, chemically strengthened, anti-reflective film, shatter-proof
Operating range: 0 to 40 degrees C, 10 to 80% humidity
Power: AC 100-240V, 50/60Hz, built-in power, typical 70W, maximum 230W

The panel supports portrait and landscape mounting. Inputs include one HDMI and one DP, with a DP output for daisy-chaining the signal to a second unit. Control is available through RS232C, LAN, IR and USB 2.0 Type A ports. Software compatibility covers SuperSign CMS, SuperSign Control+, SuperSign Cloud, Mobile CMS and Connected Care.

Where it fits in Qatar

A jeweller on a busy street in Doha can run product films on the glass while the shop floor stays visible from outside. In West Bay, a corporate lobby can overlay visitor directions and sponsor messages on a glass partition without blocking the reception desk. A showroom in Lusail or The Pearl can use the display to present a product in front of the furniture or fittings it sits among.

What to plan before ordering

The head weighs 14.1 kg and the signage box 2.6 kg, so the wall or frame needs proper load planning. The head measures 1237.6 x 717.9 x 86.5 mm, and the design includes M4 screw holes at all rear corners, a tiling bracket and wing brackets. A free site survey from SmartRooms Qatar helps confirm the fixing points and power route. Because the rated operating temperature tops out at 40 degrees C, a window-facing position in Qatar summers needs an air-conditioned, shaded or sheltered environment; confirm the location with our team before installation. The package includes a DP cable, LAN cable, RS232 cable and a remote with batteries.

Questions about 55EW5P-M

What is the LG 55EW5P-M used for?

The LG 55EW5P-M is a transparent OLED signage display that shows content while keeping the area behind it visible. It suits shop windows, hotel lobbies, showrooms and reception areas where a solid screen would block the view. Its 43% transparency lets the room or product on display remain part of the visual message.

How transparent is the screen and what does that affect?

The panel is rated at 43% transparency, measured under SET conditions. Dark content appears to float over the background, while bright content reads more strongly. Content choice matters, so plan layouts with plenty of contrast and clear text. Our team can review your artwork against the specification before you order.

Can it be installed in a shop window exposed to Doha summer sun?

The rated operating temperature is 0 to 40 degrees C with 10 to 80% humidity. Qatar summer heat can exceed 45 degrees C outside, so a window-facing position needs an air-conditioned or well-shaded environment. Confirm the exact location with the SmartRooms Qatar team and request a free site survey before deciding on the mounting point.

Does the LG 55EW5P-M support portrait orientation?

Yes. The source data lists both portrait and landscape operation. Portrait mounting suits vertical product displays, directional signs in corridors and narrow shop frontages in Msheireb or Al Sadd. Specify the orientation in your quote request so the bracket and content layout can be planned together.

Which connections does the display provide?

The inputs include one HDMI port with HDCP 2.2/1.4, one DP input with HDCP 1.3, one RJ45 LAN input, one RS232C input, one IR input with an external IR receiver and two USB 2.0 Type A ports. Outputs include DP, audio, RS232C and LAN, allowing a daisy-chained signal to a second unit.

Can several units be linked into one transparent wall?

Yes. The product can be installed as a single unit or as a larger transparent wall, and it includes a DP output for daisy-chaining the signal. Each unit needs its own mounting plan, power point and content feed. A wall of several panels in a Lusail showroom or West Bay lobby should be planned during the site survey.

How is content managed and which software is compatible?

The display runs webOS 7.5 with 16GB internal eMMC memory. Compatible software listed in the data includes SuperSign CMS, SuperSign Control+, SuperSign Cloud, Mobile CMS and Connected Care. Features include local content scheduling, group management, fail over, local network sync, status mailing and wake on LAN, which help organisations manage several screens.

How heavy is the panel and what does mounting need?

The head weighs 14.1 kg and the signage box weighs 2.6 kg, with a packed weight of 30.0 kg. The rear has M4 screw holes at all corners, and tiling and wing brackets are included. Because the panel is large and transparent, the wall, frame or glass structure must be checked for load and alignment during a free site survey.

Does the power supply suit Qatar mains?

The power supply is rated for AC 100-240V at 50/60Hz with built-in power, so it covers Qatar's 240 V, 50 Hz mains. Typical consumption is 70W and maximum is 230W. The power cord is included; the SmartRooms Qatar team can confirm that it fits the socket planned at your site before installation.

What comes in the box?

The package includes a remote controller with two batteries, a power cord, quick start guide, IR receiver, regulation book, RS232C adapter, MCX harness cables, a DP cable of 2 m, a LAN cable of 1.5 m, an RS232 cable of 1.5 m, an LC cable of 3 m, screws, cable rubber, cable caps, tiling brackets and signage box wing brackets.

Is a site survey needed for a lobby installation in Lusail?

Yes, a site survey is strongly recommended. It checks the glass or partition strength, the wall fixings for a 14.1 kg head, the power route and the room temperature. SmartRooms Qatar provides free site surveys, so we can recommend mounting options and cable paths before you place the order.

Can a government or school buyer order this through an LPO or tender?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, with payment by bank transfer, cheque or purchase order. Products are covered by the manufacturer's warranty. For a school or ministry ordering this display, send the quantity, mounting location and tender reference when requesting a quote.
