Overview

The LG 55EF5F-L is a discontinued 55-inch OLED signage panel from the OLED EF5 series, with 1,920 x 1,080 Full HD resolution, a 150,000:1 contrast ratio and support for landscape or portrait mounting. It suits organisations in Qatar that already run this model or need a current equivalent for lobby walls, atriums and reception areas. Request a quote for a current equivalent or compatible replacement.

What the 55EF5F-L was built for

The LG 55EF5F-L is a 55-inch OLED signage display from the OLED EF5 series, designed for locations where the screen is part of the architecture itself. It is sold as an open-frame head with a separate signage box, so it can be built into a wall, a column or a custom enclosure. LG has discontinued this model. This page is written for organisations that already run one, buyers comparing it with newer displays, and anyone in Qatar who needs a current equivalent or a compatible replacement.

Picture figures that matter on site

The panel has a native resolution of 1,920 x 1,080 (Full HD) at a 16:9 aspect ratio. Its self-lit OLED pixels give a contrast ratio of 150,000:1. Typical brightness is 400 cd/m² at APL 25% (average picture level) and 150 cd/m² at APL 100%, so full-white content looks dimmer than a mixed image. The rated viewing angle is 178 x 178 (horizontal by vertical), which keeps the picture readable from the side of a lobby. Typical panel life is 30,000 hours, and the rated operation is 18 hours a day, seven days a week, for moving video only.

Tiling, curves and connections

The 55EF5F-L runs in landscape or portrait. Its flat, off-bezel measurement is 0.6 mm at the top and bottom and 6.7 mm at each side, which keeps seams narrow when several units are tiled. The head is 12.4 mm deep, or 38.0 mm with the pem-nut fixings, and weighs 6.6 kg. The 55EF5F series supports concave and convex curvature, and the optional Curvature Calibrator (ACC-CC-EF5E) is the accessory for matching displays to a chosen curve. Units tiled on a LAN daisy chain can be controlled, monitored and updated together, and each display plays its part of the video in sync through its built-in SoC. Supported management software includes SuperSign CMS for content, SuperSign Control+ and SuperSign Control for control and monitoring, and Signage365Care.

Where it fits in Qatar

Hotel lobbies in West Bay or The Pearl: a portrait column or landscape wall for wayfinding and guest messages, with several units managed from one network.
Bank branches or corporate atriums in Msheireb or Lusail: a narrow-seam landscape wall of several panels for service updates, market information or brand films.
Private schools and universities in Doha, Al Rayyan or Education City: indoor screens for event calendars, campus information and learning content, with every panel updated centrally.

Planning an installation

Plan the space before the order. The operating range is 0°C to 40°C at 10% to 80% humidity, and Qatar summers regularly push outdoor temperatures above 45°C. Install the display in an air-conditioned indoor space and confirm the room conditions with the SmartRooms Qatar team before ordering. Power is rated at 100-240 V and 50/60 Hz, which covers Qatar's 240 V, 50 Hz supply, with a typical draw of 309 W and a maximum of 318 W on an 8-colour bar test. The packed head weighs 17 kg in a 1,350 x 837 x 250 mm carton, so check lift access and wall fixings. A free site survey confirms load, cable routes and sight lines before any drilling or frame building begins.

Because this model has been discontinued, the most useful next step is a quotation for a current equivalent or a compatible replacement. Request a quote from SmartRooms Qatar with your quantity, room size and mounting plan. We usually reply within one working day, and we can work with purchase orders (LPOs) and government tenders, including Monaqasat.

Questions about 55EF5F-L

Is the LG 55EF5F-L still available from SmartRooms Qatar?

LG has discontinued the 55EF5F-L, so this page covers the model for existing owners, comparison shoppers and buyers seeking a replacement. Request a quote and SmartRooms Qatar will recommend a current equivalent or compatible replacement that matches your 55-inch size, Full HD resolution and mounting needs. The recommendation is confirmed in writing with your quotation.

What is the 55EF5F-L built for?

It is a 55-inch OLED display for digital signage where the screen is part of the room design, such as a lobby wall in a West Bay hotel. It is sold as an open-frame head with a separate signage box, so it can be built into custom enclosures. The head weighs 6.6 kg and is 12.4 mm deep, which keeps slim wall builds practical.

What resolution and brightness does it deliver?

The panel has a native resolution of 1,920 x 1,080 (Full HD) at 16:9 and a contrast ratio of 150,000:1. The manufacturer lists typical brightness of 400 cd/m² at APL 25% and 150 cd/m² at APL 100%. These are typical values, so compare them with the room lighting and the content you plan to show before choosing this model.

Can it be used in portrait orientation?

Yes, the 55EF5F series supports both landscape and portrait orientation. Portrait mounting suits a vertical wayfinding panel in a hotel lobby or a tall display column in a corporate atrium in Lusail. Confirm the orientation with the team before ordering, because the bracket and content layout must match the position you choose.

Does the 55EF5F-L support curved installations?

The 55EF5F series supports concave and convex curvature in both orientations. Matching displays to a specific curve requires the optional Curvature Calibrator, listed as ACC-CC-EF5E. Include the required curve, the number of panels and whether the calibrator is needed in your quotation request, so the frame and content layout are planned together.

What gap is left between panels in a multi-unit video wall?

The flat, off-bezel measurement is 0.6 mm at the top and bottom and 6.7 mm on the left and right. The flat, on-bezel measurement is 5.0 mm top, 10.6 mm bottom and 7.6 mm on each side. For a branch video wall in Msheireb, the off-bezel figures give much narrower seams, but confirm bracket alignment with the installation team.

Which inputs, outputs and control ports are fitted?

Inputs are HDMI, DisplayPort and two USB 2.0 ports. The output is DisplayPort, with audio set to fixed, off or variable. External control uses RS232C in and out, RJ45 in and out, and an IR input. The display is not OPS compatible, so plan an external media player connected through HDMI or DisplayPort instead of an OPS slot.

Which software works with the 55EF5F-L?

The specification lists SuperSign CMS for content management, SuperSign Control+ and SuperSign Control for control and monitoring, and Signage365Care as supported. In a school or ministry running several screens, the LAN daisy chain lets one control path reach each display for control, monitoring and firmware updates, which reduces day-to-day management effort.

Will it run on Qatar's power supply and in the summer heat?

The power supply is rated 100-240 V at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 309 W and maximum is 318 W. The operating range is 0°C to 40°C with 10% to 80% humidity. Qatar summers regularly exceed 45°C, so install the display in an air-conditioned indoor room and confirm the conditions with the team.

What accessories come in the box?

The basic accessories are a remote controller, power cord, quick start guide, IR receiver, a regulation book, a phone-to-RS232C gender adapter, an RS232 cable with 4-pin connectors at both ends, four 220 mm FFC cables linking the panel to the signage box, a DP cable, a LAN cable and an LC cable. The Curvature Calibrator is an optional extra and is not part of the basic set.

What should be planned before mounting one in a building?

Book a free site survey before fixing anything to the wall. The survey checks the head weight of 6.6 kg, the signage box weight of 3.5 kg, FFC cable routes and sight lines. The packed head weighs 17 kg in a 1,350 x 837 x 250 mm carton, so check the entrance route for a school in Al Rayyan or a business park in the Industrial Area. Delivery covers all eight municipalities of Qatar.

What do the two variant codes mean?

The manufacturer lists two variant codes under this model: 55EF5F-L.AMA and 55EF5F-L.AMI. The source data does not explain the difference between them, so confirm which code matches the unit you are specifying before accepting a quotation. Quote the full code in your request so the specification is clear on both the quotation and the purchase order.
