LG 55EF5F-P (Discontinued) · Replacements in Qatar

Name: LG 55EF5F-P 55-inch Flexible Curved OLED Open Frame Display
Brand: LG
SKU: lg-55ef5f-p
Availability: Discontinued

Overview

The LG 55EF5F-P is a discontinued 55-inch flexible curved OLED signage display for open-frame installs. Its 1920 x 1080 panel has a 0.6 mm top and bottom off-bezel edge, supports concave and convex curves in portrait or landscape, and tiles with LAN daisy chain control. Organisations in Qatar that own it or need a replacement should request a quote.

What this discontinued OLED signage display is

The LG 55EF5F-P is a 55-inch open-frame display from the OLED EF5 series, built on a flexible OLED panel that needs no backlight unit or liquid crystal layer. LG has discontinued this model, so this page serves organisations that already run it, buyers comparing it with newer signage, and anyone seeking a replacement. The head weighs 7.8 kg and is 12.4 mm deep without pem-nut fittings, so the frame and wall structure should be planned around that thin, light profile.

Picture figures worth checking against your brief

The panel delivers a native 1920 x 1080 (FHD) image in a 16:9 aspect ratio. Typical brightness is 400 cd/m² at APL25% and 150 cd/m² at APL100%, the rated contrast ratio is 150,000:1, and the viewing angle is listed as 178 degrees horizontally and vertically. The typical panel life is 30,000 hours. Because brightness varies with picture load, compare these typical figures with the lighting in your room during a site survey.

Connectivity, control and synchronised video walls

Inputs include HDMI, DisplayPort and two USB 2.0 ports, and the display provides a DisplayPort output with audio set to fixed, off or variable. External control covers RS232C in and out, RJ45 in and out, and an IR input. The LAN daisy chain lets one controller manage and monitor every display in a group, send data and update firmware across them together. Each unit plays its own tile through a built-in SoC, which keeps synchronised content running across the wall. The model is not OPS compatible, so decide on your media player arrangement before ordering.

Inputs: HDMI, DisplayPort and two USB 2.0 ports
Outputs: DisplayPort and audio (fixed, off or variable)
Control: RS232C, RJ45 and IR

Curvature, bezels and layout planning

The series supports concave and convex curvature in both portrait and landscape orientations. The optional Curvature Calibrator (ACC-CC-EF5E) coordinates displays with different curvatures when a layout needs it. Bezel width on flat, off-bezel units is 0.6 mm top and bottom and 6.7 mm left and right, while on-bezel units measure 5.0 mm top and bottom, 7.8 mm left and 13.2 mm right. Check these figures against the drawings, together with the included tiling set fixers and flex bars, before the wall is built.

Where it fits in Qatar

Three situations suit this model. A serviced apartment building in Lusail could use a curved feature wall in its lobby, where the panel becomes a landmark for arriving guests. A shopping mall in West Bay could tile several units to show promotions along a long corridor, with one controller managing the group. A government customer service hall in Doha could mount a unit in portrait to show queue and information content, using the Curvature Calibrator if the curve must match a counter design.

Environment matters more in Qatar than in most markets. The rated operating range is 0°C to 40°C with 10% to 80% humidity, and Doha summer temperatures can exceed 45°C. Keep the display in air-conditioned interior spaces, away from direct sunlight, windows and glass facades, and confirm the room conditions with the SmartRooms Qatar team before installation.

What to plan before you order

The power supply is listed as 100-240V~, 50/60Hz with built-in power, drawing 309 W typical and 318 W maximum on an 8 colour bar test.

Questions about 55EF5F-P

Is the LG 55EF5F-P still sold new by LG?

No. LG has discontinued the 55EF5F-P, so the manufacturer no longer lists it as a current product. If your organisation needs a 55-inch curved or open-frame signage display, SmartRooms Qatar can quote a current equivalent or a compatible replacement. Send the room dimensions, mounting plan and software you use, and our team will match the options to your brief before you commit to a purchase.

Who is this display suited to?

It suits organisations that want a 55-inch curved landmark display with OLED picture quality, such as a serviced apartment building in Lusail upgrading a lobby feature wall, or a hotel in West Bay adding a curved information screen. Because the model is discontinued, it is also relevant to existing owners who need matching units to extend an installation, and to buyers comparing it with newer models.

What resolution and brightness does it offer?

The panel has a native resolution of 1920 x 1080 (FHD) and a 16:9 aspect ratio. Typical brightness is 400 cd/m² at APL25% and 150 cd/m² at APL100%, and the rated contrast ratio is 150,000:1. Because brightness varies with picture load, compare these typical figures with the lighting in your room during a site survey before choosing content and placement.

Can it be mounted in portrait and in curved shapes?

Yes. The series supports landscape and portrait orientation, and concave and convex curvature in both. The optional Curvature Calibrator (ACC-CC-EF5E) coordinates displays with different curvatures, which helps when a curved wall must match a reception counter, a column or an atrium wall in a Doha building. Confirm the curve and orientation on drawings before the frame is fixed.

Can I use it near windows or in a hot entrance in Qatar?

Not without climate control. The rated operating range is 0°C to 40°C with 10% to 80% humidity, and Qatar summer temperatures can exceed 45°C. Install it in air-conditioned interior spaces, away from direct sunlight, glass facades and open entrances. If you are unsure about the conditions in a particular room, confirm them with the SmartRooms Qatar team before ordering.

How many hours a day can it run?

The manufacturer rates operation at 18 hours a day, seven days a week, for moving video only. The typical panel life is 30,000 hours. In a mall corridor or lobby loop that runs all day, plan the playlist so the display stays within its rated hours, and schedule static content with care.

Can several units be tiled into one video wall?

Yes. Each display plays its own tile through a built-in SoC for synchronised playback, and the LAN daisy chain lets one controller manage, monitor, send data to and update firmware on the units together. Tiling set fixers and flex bars are included. In a four-unit wall in an atrium in Msheireb, for example, the bezel measurements and cable runs would be checked first.

Is it compatible with OPS media players?

No. The manufacturer lists OPS type compatibility as No, so a standard OPS computer module cannot be fitted to this model. Plan your media player arrangement before ordering and confirm it with the SmartRooms Qatar team, so the content workflow suits your site and your playback needs.

What connections and control options are there?

Inputs are HDMI, DisplayPort and two USB 2.0 ports. The DisplayPort output and the audio output, set to fixed, off or variable, allow the signal to pass on to another display. External control covers RS232C in and out, RJ45 in and out, and an IR input. The IR receiver and RS232 cable are supplied, so the display can be linked into an existing AV control system.

Which software works with it?

The model is listed with SuperSign CMS for content management and SuperSign Control+ and Control for control and monitoring, and Signage365Care is listed as supported. A private school in Al Rayyan fitting out a corridor of information screens could manage all its content from one place. Ask the SmartRooms Qatar team to confirm the setup you need within your quotation.

What comes in the box, and what is optional?

The box includes a remote controller, power cord, quick start guide, IR receiver, DP cable, LAN cable, RS232 cable, FFC cables for the panel and signage box, tiling set fixers, flex bars, screws and tapes. The Curvature Calibrator (ACC-CC-EF5E) is an optional extra. Compare the contents with your quotation on delivery so the installation team has every part before work starts.

What power does it need, and can several units be ordered on an LPO?

It runs on 100-240V~, 50/60Hz with built-in power, drawing 309 W typical and 318 W maximum. Confirm that the supplied power cord and the sockets in your building suit BS 1363 outlets. Schools, ministries and companies ordering several units can raise a purchase order or LPO, and we can arrange a free site survey before the order is placed.
