Brand: LG
SKU: lg-55tnf5j
Availability: Discontinued

Overview

The LG 55TNF5J is a 55-inch open-frame touch display for kiosks, and LG has discontinued it. Its in-cell touch layer allows a slim, narrow-bezel frame and recognises up to 10 simultaneous touch points, while webOS 6.0 runs signage content directly on the panel. It suits banks, hospitals and government service points in Doha that need to replace or extend an existing kiosk. Request a quote for a current equivalent or compatible replacement.

What the LG 55TNF5J is

The LG 55TNF5J is a 55-inch open-frame touch display from the Kiosk Touch TNF5J series. LG has discontinued this model, so this page is written for organisations that already run one, buyers comparing it with newer kiosk displays, and anyone who needs a replacement that matches an existing installation. SmartRooms Qatar can quote a current equivalent or a compatible replacement.

Touch built into the panel

Most touch screens bond a separate sensor film over the glass. On the 55TNF5J the touch function sits inside the display itself, which allows a slimmer frame and a narrower bezel: 9.1 mm on three sides and 16.1 mm on the fourth. Without an extra film layer, the image avoids the milky appearance that film can add. Touch registers objects from 6 mm in diameter, is rated at 3.5 mm ±0.5 mm accuracy and recognises up to 10 points at once.

Panel and display performance

Resolution: 3,840 x 2,160 UHD on an IPS panel
Brightness: 450 nit with a 1,000:1 contrast ratio
Colour: 10-bit, 1.07 billion colours, NTSC 72% gamut
Viewing angle: 178 degrees horizontal and vertical
Orientation: portrait or landscape, with installation tilted up to 45 degrees face-up

Connections, software and power

The display provides two HDMI inputs supporting HDCP 2.2/1.4, an RJ45 LAN port, RS232C and IR inputs, a USB 2.0 Type A port and an audio output. Touch data travels over a USB 2.0 Type B link. webOS 6.0 with 8GB of internal memory includes local content scheduling, group management, fail-over, Wake on LAN, SNMP and HDMI-CEC control, and it supports SuperSign CMS, SuperSign Control and Signage 365 Care. The built-in power supply accepts 100-240 V AC at 50/60 Hz, which covers Qatar's 240 V mains. Typical draw is 127 W and maximum 170 W. Mounting uses a 300 x 300 VESA pattern, and the head weighs 16.8 kg and measures 1231.8 x 709.6 x 39.2 mm.

Where it fits in Qatar

In a Doha hospital, the display can sit at a registration area for self-service check-in, provided it is inside an air-conditioned space, because its rated operating range is 0 °C to 40 °C. In a bank branch in West Bay, it can present service information or a self-service menu to customers waiting in line. A shopping centre in Lusail can use it for interactive wayfinding, with content managed from a central office. Summer temperatures in Qatar regularly pass 45 °C, so the unit should not be placed in outdoor kiosks or in lobbies without climate control.

What to plan before ordering

Before ordering a replacement or an extension, compare the existing opening with the body dimensions, check the 300 x 300 VESA pattern and the 16.8 kg head weight, and map the network and cable routes. SmartRooms Qatar offers free site surveys, professional installation and delivery to all 8 municipalities of Qatar. Purchase orders (LPOs) and government tenders are accepted, and the product is covered by the manufacturer's warranty. Send the model number and site details, and request a quote from SmartRooms Qatar for a current equivalent or compatible replacement. Quotations usually follow within one working day.

Questions about 55TNF5J

Has LG discontinued the 55TNF5J?

Yes. LG has discontinued this 55-inch touch kiosk display, so it is no longer in the current LG range. If you already run one or need to replace a failed unit, SmartRooms Qatar can quote a current equivalent or a compatible replacement. Send the model number with your site details, and a quotation usually follows within one working day.

What is the 55TNF5J designed for?

It is a 55-inch open-frame touch display for kiosks and self-service points where visitors touch the screen directly. Its UHD IPS panel and 24/7 operating rating suit public-facing points in banks, hospitals and government service halls that run through the working day.

How does the built-in touch layer differ from a film-based touch screen?

Touch is built into the display rather than added as a separate film sheet. This allows a slim design with a bezel of 9.1 mm on three sides and 16.1 mm on the fourth, and it avoids the milky look that film layers can add. Touch accuracy is rated at 3.5 mm ±0.5 mm, with up to 10 simultaneous points.

Can it be mounted at an angle on a kiosk counter?

Yes. The display supports portrait and landscape orientation and can be installed tilted up to 45 degrees face-up, which suits counter-height kiosks where users look down at the screen. Mounting uses a 300 x 300 VESA pattern. Confirm that the frame can carry the 16.8 kg head before fixing it.

Will it cope with Qatar's summer heat, for example in an outdoor kiosk?

No. The rated operating temperature is 0 °C to 40 °C with 10% to 80% humidity, so the display must sit in an air-conditioned space. Qatar's summer temperatures can exceed 45 °C, so outdoor kiosks and lobbies without climate control are not suitable. Confirm site conditions with the SmartRooms Qatar team before installation.

What power and cooling figures should I plan for in Qatar?

The built-in power supply accepts 100-240 V AC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 127 W and maximum is 170 W, equal to 433 and 580 BTU/hr. Use these figures when sizing a booth enclosure or calculating the air-conditioning load for a small office.

Which devices can it connect to?

It has two HDMI inputs supporting HDCP 2.2/1.4, an RJ45 LAN port, RS232C and IR inputs, a USB 2.0 Type A port and an audio output. Touch data goes to the computer over USB 2.0 Type B, and the manufacturer lists Windows 10 for touch support. Check your computer's ports before ordering cables.

Can it play content without a separate media player?

Yes. webOS 6.0 with 8GB of internal memory runs signage content on the display itself. Its tools include local content scheduling, group management, fail-over and screen rotation, and it supports SuperSign CMS, SuperSign Control and Signage 365 Care. A retail operator in Msheireb could update content across several screens from one office.

How can a school or government office manage several units?

The display supports Wake on LAN, SNMP and status mailing, which help an IT team monitor units from a central office. These features suit a school in Al Wakrah ordering several units, where a purchase order (LPO) can cover the order and delivery reaches all 8 municipalities of Qatar.

Does the on-screen menu support Arabic?

Yes. The on-screen display languages include Arabic alongside English, French and many others, which helps bilingual Arabic and English teams. Specify the menu language needed for each unit when you request a quote.

What is included in the box?

The package includes a 1.55 m power cord, a 1.8 m USB Type A to Type B cable, a remote controller with two batteries, an RS232C gender accessory, an IR receiver, a user manual and a quick start guide. Review the accessory list with the SmartRooms Qatar team when you define your order.

What should I check before ordering a replacement?

Measure the existing opening against the 1231.8 x 709.6 x 39.2 mm body, confirm the 300 x 300 VESA pattern and the 16.8 kg weight, and note the network and cable routes. SmartRooms Qatar offers free site surveys and professional installation, and purchase orders and government tenders are accepted. The product is covered by the manufacturer's warranty.
