Name: LG 55EF5G-P 55-inch Flexible Curved Open Frame OLED Signage
Brand: LG
SKU: lg-55ef5g-p
Availability: Discontinued

Overview

The LG 55EF5G-P is a 55-inch curved OLED signage panel that LG has discontinued. Its 1,920 x 1,080 OLED panel offers a 150,000:1 contrast ratio, supports portrait and landscape mounting, and can be managed in groups over a LAN daisy chain. Organisations that already run this model, or need a comparable curved display for a lobby, corridor or video wall in Qatar, can request a quote for a current equivalent.

A 55-inch curved OLED panel designed for landmark walls

The LG 55EF5G-P is a 55-inch OLED signage display from LG's EF5 series, designed to be tiled and curved rather than used as a single flat screen. Each panel has a native resolution of 1,920 x 1,080 (FHD) and can be mounted in portrait or landscape. LG has discontinued this model. This page serves organisations that already run it, buyers comparing it with newer displays, and anyone who needs a replacement for an existing wall.

Picture quality that holds up in a public space

OLED pixels produce their own light, so the panel needs no backlight and reaches a contrast ratio of 150,000:1. Brightness is rated at 150 nits at 100% APL and 400 nits at 25% APL. The panel covers 120% of the BT709 colour gamut, supports 10-bit colour depth with 1.07 billion colours, and has a 1ms G-to-G response time. A 2H hard coating and typical reflectance of 1.2% help limit glare, and the viewing angle is rated at 178 degrees horizontally and vertically.

Curved layouts, bezel widths and mounting weight

The series supports concave and convex curvature in both portrait and landscape. An optional Curvature Calibrator (CC) helps coordinate panels to a chosen curve, so a team can adjust the design on site. Bezel width changes how a tiled wall looks. In landscape with the bezel off, the top and bottom edges measure 0.6 mm and the sides 6.7 mm. With the bezel on, the sides measure 7.6 mm and the bottom 10.6 mm. The landscape head weighs 5.8 kg, the portrait head 7.0 kg, and the signage box 3.5 kg. The landscape head measures 1224.9 x 696.2 x 38.0 mm, listed with the Pemnut component.

Inputs: one HDMI (HDCP 1.4), one DisplayPort (HDCP 1.3), RS-232C, LAN and IR inputs, and two USB 2.0 Type A ports.
Outputs: DisplayPort, audio, RS-232C with IR out, and LAN, so signal and control can pass to the next panel.

Where this model fits in Qatar

A hotel in West Bay could use a curved wall of these panels behind reception, showing wayfinding and property information in portrait and landscape. A university in Education City might tile a corridor wall, where the LAN daisy chain lets facilities staff control, monitor and update every panel from one point. A transport concourse near the Hamad International Airport area could use a curved column, provided the panels sit inside an air-conditioned space.

Planning a curved OLED installation in Qatar

The operating temperature is rated at 0°C to 40°C, with humidity between 10% and 80%. In Qatar, where summer temperatures can exceed 45°C, keep units inside climate-controlled areas, away from sun-exposed windows and open-air positions. Power input is rated AC 100-240V at 50/60Hz with built-in power. Typical consumption is 309 W (maximum 318 W), or 1054 BTU/hr typical and 1085 BTU/hr maximum, which the cooling design should cover. The operation rating is 18 hours a day, 7 days a week, for moving content only, so static menus should not be the main use.

Because the model is discontinued, send SmartRooms Qatar your wall dimensions, panel count and target curve. Site surveys are free, and quotations usually arrive within one working day. Request a quote for a current equivalent or a compatible replacement, and include the expected installation area so the team can confirm fit before you buy. Supply and delivery cover all eight municipalities of Qatar, with professional installation available.

Questions about 55EF5G-P

Is the LG 55EF5G-P still sold new by LG?

No. LG has discontinued the 55EF5G-P, so this model is no longer available new from the manufacturer. If your project needs a curved OLED signage display of similar size, SmartRooms Qatar can quote a current equivalent or a compatible replacement. Send your site drawings and the number of panels with your request so the team can check fit and control requirements.

What is the 55EF5G-P best suited for in Qatar?

It suits organisations building a landmark or wayfinding feature from several panels, such as a curved reception wall in a West Bay hotel or a column in a transport concourse. Its 55-inch size and portrait or landscape mounting let you tile units into custom shapes. Because its operation rating is for moving content only, it fits animated wayfinding and advertising better than static menus.

How bright is the panel for a daytime lobby with large windows?

The panel is rated at 150 nits at 100% APL and 400 nits at 25% APL. Full-white content measures at the lower 100% APL rating, so a bright lobby facing the sun should be tested before ordering. During a free site survey, SmartRooms Qatar can review your lighting and sightlines and advise on placement before you finalise the layout.

Can the 55EF5G-P operate in Qatar's summer heat?

The source rates operation from 0°C to 40°C, with humidity from 10% to 80%. Install it in an air-conditioned lobby or corridor, not in an open atrium or a sun-exposed position where summer temperatures above 45°C could take the environment beyond its rating. The model includes a temperature sensor and a fan, but these do not extend its rated range.

How many panels can be linked in a LAN daisy chain?

The LAN daisy chain lets you control, monitor, transmit data and update firmware across connected displays together. The source data does not state a maximum number of panels per chain, so the SmartRooms Qatar team should confirm chain length for your wall before a quote is issued. Include your planned panel count in the request so this can be checked.

How does the video wall sync playback work?

Each display has a built-in high-performance SoC that plays its own video tile, so panels in the wall stay in step for synchronised content. The data also lists Tile Mode Setting, Gapless Playback and Video Tag support with four tags. A university corridor or hotel reception wall can therefore run one piece of content split across several panels.

Which inputs and outputs does the 55EF5G-P have?

Inputs are one HDMI (HDCP 1.4), one DisplayPort (HDCP 1.3), one RS-232C, one LAN, one IR receiver and two USB 2.0 Type A ports. Outputs are one DisplayPort, one audio, RS-232C with IR out, and one LAN. The DisplayPort and LAN outputs let a source or control signal pass to the next panel in a wall.

How heavy is each unit and what does mounting need?

The head weighs 5.8 kg in landscape and 7.0 kg in portrait, and the signage box weighs 3.5 kg. A curved frame of several panels needs a structure rated for the full load, with room for the signage box. SmartRooms Qatar offers free site surveys and professional installation, so mounting points can be checked before any equipment is delivered.

Does the model support curved installations, and is the calibrator included?

Yes. The series supports concave and convex curvature in both portrait and landscape orientations. The Curvature Calibrator (CC) is listed as optional in the source data, so confirm whether it is included in your quote. It helps coordinate panels to a chosen curve, which lets a project team adjust the shape on site.

What power and cooling load should be planned?

The power input is rated AC 100-240V at 50/60Hz with built-in power, which covers Qatar's 240 V mains. Typical consumption is 309 W and maximum is 318 W, equal to 1054 BTU/hr typical and 1085 BTU/hr maximum. A facilities manager should include that heat load in the air-conditioning plan for the room, particularly for a grouped wall of several panels.

Can a school or ministry buy this model through an LPO or tender?

Yes, SmartRooms Qatar supplies on purchase orders (LPOs) and government tenders, including Monaqasat. Because the model is discontinued, a procurement team should specify the required size, curvature and connectivity, and request a quote for a current equivalent or compatible replacement. Payment can be made by bank transfer, cheque or purchase order.

I already run 55EF5G-P panels. Can I extend my wall with a matching unit?

If you already operate this model and want to extend a wall, list your current panel count, bezel arrangement and curve when requesting a quote. SmartRooms Qatar can review whether a current model matches your existing frames and mounting points. Expansion is often easier to plan when the existing layout is measured before any new units are ordered.
