LG 55EF5K-P (Discontinued) · Replacements in Qatar

Name: LG 55EF5K-P 55-inch Flexible Curved OLED Signage Display (Discontinued)
Brand: LG
SKU: lg-55ef5k-p
Availability: Discontinued

Overview

The LG 55EF5K-P is a 55-inch flexible curved OLED signage display from the EF5 series, and LG has discontinued this model. It offers a Full HD OLED panel at 1920 x 1080, a 150,000:1 contrast ratio, a 120Hz refresh rate and 0.6 mm top and bottom bezels in portrait orientation. Hotels, malls and institutions in Qatar that already run this unit, or are weighing a curved landmark wall, should request a quote for a current equivalent or compatible replacement.

Why the LG 55EF5K-P matters to buyers today

The LG 55EF5K-P is a discontinued 55-inch flexible curved OLED signage display from LG's EF5 series. It is built as an open-frame panel for architectural and landmark installations, where the screen forms part of the building design. LG has discontinued this model, so this page serves three groups: organisations that already run it and need spares or extensions, buyers comparing it with newer curved signage, and anyone who needs a replacement that fits an existing layout. SmartRooms Qatar can quote a current equivalent or a compatible replacement.

Panel facts that shape the installation

The OLED panel has a native resolution of 1920 x 1080 (Full HD) in a 16:9 format and a 120Hz refresh rate, so moving content on a curved surface stays smooth. OLED pixels emit their own light, so the panel needs no backlight layer. LG rates the contrast at 150,000:1 and gives brightness as 150 nits at 100% APL and 400 nits at 25% APL. Judge that brightness against the light in the room rather than a single headline figure.

Viewing angle of 178 degrees horizontal and vertical
1.07 billion colours with a BT.709 120% colour gamut
Typical panel life of 30,000 hours
Rated 18 hours a day, seven days a week, for moving content

Curved layouts, tiling and remote control

The EF5K series supports concave and convex curvature, and LG lists an optional Curvature Calibrator for on-site coordination of curved displays. Ask our team whether that option is available for this model before you plan a bespoke curve. For larger walls, panels can be tiled horizontally and vertically. The LAN daisy chain lets one operator control, monitor, transmit data and update firmware across the set, while built-in processing keeps each tile in sync during playback. The unit has 16GB of internal eMMC storage and runs webOS 4.0.

Where it fits in Qatar

In a hotel reception in West Bay or Lusail, a curved panel can frame a check-in wall and carry welcome content through the day. A shopping mall atrium in Msheireb can use a tiled set to draw visitors toward a central court. At a university or training centre in Education City, a curved foyer display can show wayfinding and event listings. Each of these sites is indoor and air-conditioned, which matches the unit's operating range.

What to plan before you order

Confirm that the room holds ambient temperature between 0 °C and 40 °C with humidity from 10% to 80%. Typical power draw is 309 W and maximum is 318 W, and the built-in power accepts 100-240 V AC at 50/60 Hz. The head weighs 7.0 kg in portrait and the packed unit 17.6 kg, so plan for handling by a team and a site survey before fixing to a wall. The basic kit includes FFC cables, tiling set fixers, flex bars, a remote with batteries and a 2 m DP cable.

Tell us your wall dimensions, the number of panels and your current content system, and we will confirm a current equivalent or compatible replacement. Request a quote from SmartRooms Qatar and we will return a written quotation, usually within one working day.

Questions about 55EF5K-P

Is the LG 55EF5K-P still sold by LG?

No. LG has discontinued the 55EF5K-P, so it is no longer available from the manufacturer as a new product. SmartRooms Qatar can quote a current equivalent or a compatible replacement for your site, and we will check the replacement against your mounting, power and content setup before you order. Request a quote with your current model number and the number of panels you need.

What is the LG 55EF5K-P designed for?

It is a 55-inch open-frame OLED signage display for public and commercial spaces where a curved screen is part of the design, such as hotel reception walls, retail atriums and landmark walls. Its flexible design lets integrators build concave or convex shapes in portrait orientation, and the OLED panel delivers deep blacks and a 178-degree viewing angle for visitors approaching from the side.

What resolution and brightness does it offer?

The panel has a native resolution of 1920 x 1080 (Full HD) in a 16:9 aspect ratio, with a 120Hz refresh rate. LG specifies brightness as 150 nits at 100% APL and 400 nits at 25% APL, with a contrast ratio of 150,000:1. For a bright lobby with windows, compare the 25% APL figure with the room's light level before deciding on placement.

Can it go in a hot outdoor area or a sun-facing lobby in Qatar?

Not as specified. Its operating range is 0 °C to 40 °C with 10% to 80% humidity, and summer temperatures in Qatar often pass 45 °C. Place it in air-conditioned indoor space and check that sun-facing glass does not push the room above 40 °C. The data does not list an IP rating, so do not plan it for dusty or outdoor sites without confirming with our team.

How do I connect several panels into one video wall?

Tile the panels horizontally and vertically, then use the LAN daisy chain to control and monitor all displays from one point. The HDMI or DP input can be passed along through DP output, and the built-in processing lets each panel play its own video tile in synchronised playback. The kit includes tiling set fixers, flex bars and FFC cables. A foyer wall in Education City needs its cabling plan confirmed before ordering.

Does it support portrait and landscape orientation?

The specification lists portrait orientation as supported and landscape as not listed as supported. Portrait is the orientation shown in the mechanical data, including the 701.4 x 1219.7 mm head size. If your design needs landscape panels, confirm the orientation with our team before you request a quote, so the replacement suits the wall you are building.

What power does it need in Qatar?

The power supply is built in and accepts 100-240 V AC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains supply. Typical consumption is 309 W and maximum is 318 W, with 0.5 W in power-off mode. Heat output is about 1,054 BTU/hr typical. Budget for this load across a multi-panel wall and have a qualified electrician check the circuit before installation.

Which content management software works with it?

The unit is listed as compatible with SuperSign CMS, SuperSign Control+, SuperSign WB, Mobile CMS and Connected Care. Crestron Connected is listed as supported, and it offers SNMP, Wake on LAN and HDMI-CEC for remote management. SuperSign Cloud is listed as not supported, so a cloud-only plan needs checking. Confirm your CMS version with the SmartRooms Qatar team when you request a quote.

What comes in the box?

The basic kit includes a remote controller with two batteries, a power cord, a quick start guide, an IR receiver, a regulation booklet, a phone-to-RS232C adapter, FFC cables for the signage box, a 2 m DP cable, a 1.5 m LAN cable, a 1.5 m RS232 cable, a 3 m LC cable, cabling tape, screws, a shield cover, six tiling set fixers and two flex bars. The source data lists no optional accessories for this model.

How much space and weight should I plan for?

The head weighs 7.0 kg in portrait and the signage box 3.5 kg, with a packed weight of 17.6 kg for the portrait unit. The head measures 701.4 x 1219.7 mm and is 38.0 mm deep with mounting nuts fitted, or 12.4 mm without them. The signage box measures 413 x 353 x 57.3 mm. Ask for a site survey before fixing curved panels to walls, especially in a tall atrium such as one in Msheireb.

Can a school or ministry buy several units through an LPO?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and supplies and delivers to all eight municipalities of Qatar. A school in Al Wakrah fitting out a foyer curved display, for example, can order the panels, cabling kit and installation together under one LPO once the quotation is confirmed. Payment is by bank transfer, cheque or purchase order.

How long does LG provide security updates?

LG states security update support for five years from the product launch date, as shown in its data for this model. That is a software support period, not a warranty term. Products are covered by the manufacturer's warranty, which applies separately to the hardware. For a discontinued model, check the launch date and the planned support period before deciding how long to run the panel at a government or school site.
