55EJ5C

What the LG 55EJ5C is built to do

The LG 55EJ5C is a 55-inch OLED display from the OLED EJ5 series, designed as a tile in a video wall or as a slim feature screen mounted flat against a wall. Each pixel produces its own light, so black areas switch off completely and the panel does not show the light bleed common on backlit LCD screens. That combination gives high contrast and a clean, deep black in the lobbies, showrooms and control areas where Qatari organisations use wall displays to present information and brand content.

The panel resolution is 1,920 x 1,080 (FHD). At 55 inches it suits content viewed from a moderate distance, such as wayfinding, dashboards, menus and presentations.

Where it fits in Qatar

A corporate headquarters in West Bay can use a tiled 55EJ5C wall in its reception to show company updates, client messages and bilingual wayfinding, with the narrow bezels keeping the display looking like a single surface. A university atrium in Education City might use a row of panels in a shared study hall to show timetables and research highlights. In Lusail, a retail flagship can place a single panel at the entrance, where the thin profile suits a glass-fronted shopfront kept inside an air-conditioned space.

Planning a 55EJ5C installation

Start with the wall. The head is only 3.65 mm deep, but the separate signage box needs its own space and a cable route to the screen, so include it on the layout drawing from the start. Dedicated slim brackets are available for video-wall work, and a wall-mount plate with screws is supplied. An optional U-Leg bracket can hold the signage box, and an optional FPC cable cover can neaten the link between box and head.

Climate is the main limit. The operating range is 0°C to 40°C with 10% to 80% humidity, while summer temperatures in Qatar can exceed 45°C. Mount the panels only in air-conditioned rooms and keep them out of direct sun through windows. Power is 100-240V~ at 50/60Hz, so the supply range covers Qatar's 240 V mains.

What to prepare before you request a quote

• Wall dimensions, panel count and the number of panels per row and column.
• Content source, such as a media player or OPS module, and the software you plan to use.
• Control needs, including whether you must integrate with an existing RS232C or LAN system.
• Room conditions, including temperature control and sun exposure.

SmartRooms Qatar offers free site surveys, so our team can measure the wall, check room conditions and confirm the layout before quoting.
