Overview

The OneScreen Touchscreen TL7 Business 55 is the most compact model in its series, a 55-inch 4K UHD interactive display with 40-point infrared touch and Android 11 built in. It runs on 8 GB RAM and 64 GB storage, includes an OPS slot for a PC module, and carries a 3-year standard warranty. It suits huddle rooms and small classrooms in Doha and Lusail.

What the 55-inch TL7 Business is built for

The TL7 Business 55 is the smallest panel in the OneScreen TL7 Business range, a 55-inch 16:9 display with a 4K UHD resolution of 3840 × 2160 pixels. It fits rooms where a full-size board would overwhelm the space: a huddle room on a floor of a West Bay office, a small seminar room at a training centre in Education City, or a primary classroom in Al Wakrah where pupils sit close to the screen. The panel carries a 400 cd/m² brightness rating, a 178° viewing angle and a 60Hz refresh rate, so content stays readable for people seated at the sides of the room.

Touch, computing and the software a meeting room needs

Touch uses zero bonding infrared technology (Gen 2) with 40 touch points, an accuracy of 1.5 mm and a response time below 7 ms. That accuracy matters when a teacher writes small text with a stylus or when several people annotate the same slide. The unit runs Android 11 on a quad-core ARM Cortex A55 processor (up to 1.8 GHz) with 8 GB RAM and 64 GB storage, so its whiteboard and annotation tools work without a separate computer. An ambient light sensor adjusts brightness to the room, and the manufacturer's OneScreen Central software is designed to manage several panels and devices from one place for IT teams.

Connecting laptops and other sources

Two HDMI inputs on the side and one on the front, plus an HDMI output
A front USB Type-C port rated 65W PD for charging a laptop during presentations
Wi-Fi 6 on 2.4 GHz and 5 GHz, Gigabit Ethernet and Bluetooth 5.2
An OPS PC slot, two side USB 3.0 ports and two RJ-45 ports
An RS-232 port for control, plus a VGA input with audio for older sources

In a Doha meeting room that connects with teams abroad, the front Type-C port and the touch USB make it simpler to run a laptop and other sources from one table. Two stylus pens with an anti-bacterial coating and a remote control are supplied, which helps when several presenters share the same panel.

Planning a 55-inch wall installation in Qatar

The panel weighs 57.54 lbs and measures 50.04 x 30.47 x 3.43 inches. It is specified for a VESA 400 x 200 flush wall mount, so the wall and fixing points should be checked for load and alignment before the bracket goes up. The power input is 100-240V AC at 50-60 Hz, which covers Qatar's 240 V, 50 Hz supply. Typical consumption is 160 W and the maximum is 320 W, so plan the socket position and cable route in advance. The source data does not give an operating temperature range for this model, so confirm the room environment with the SmartRooms Qatar team before placing the panel near a window or in a lobby exposed to dust and summer heat above 45°C.

SmartRooms Qatar supplies the TL7 Business 55 to all eight municipalities of Qatar, offers professional installation and free site surveys before any wall work, and issues quotations usually within one working day. Schools and offices buying several units can order against a purchase order or a government tender. Request a quote with your room dimensions and wall type, and we will confirm the most suitable mounting plan.

Questions about Touchscreen TL7 Business 55

Who is the OneScreen TL7 Business 55 best suited for?

It suits organisations that need an interactive display for small rooms rather than a lecture hall. In Qatar that usually means huddle rooms in Doha and Lusail offices, small training rooms, and classrooms where the screen sits at one end of a table. The 55-inch 4K panel gives a clear image at close range without taking up much wall space.

What screen size and resolution does it have?

The panel measures 55 inches diagonally, with a 16:9 aspect ratio and a 4K UHD resolution of 3840 × 2160 pixels. It uses an LED backlight rated at 400 cd/m², a 60Hz refresh rate, a 178° viewing angle and a blue light filter. The surface has an anti-glare and anti-fingerprint treatment, which helps in rooms with bright overhead lighting.

How accurate is the touch for handwriting and annotation?

Touch uses zero bonding infrared technology (Gen 2) with 40 touch points, an accuracy of 1.5 mm and a response time below 7 ms. This is enough for writing, underlining and marking up slides, whether one presenter or several are at the board. Two stylus pens with an anti-bacterial coating are supplied with the unit.

Does it need a computer to run presentations and whiteboard tools?

No. It runs Android 11 on a quad-core ARM Cortex A55 processor with 8 GB RAM and 64 GB storage, so its built-in whiteboard and annotation tools work without a separate computer. A laptop or PC can still be connected for applications that need one, through HDMI, USB or the OPS PC slot.

Which ports are available for connecting laptops and other sources?

The side panel has two HDMI inputs, one HDMI output, a VGA input with a VGA audio input, two USB 3.0 ports, one USB 2.0 port, a 3.5mm audio output, an RS-232 port and an OPS PC slot. The front adds one HDMI input, two USB 3.0 ports and a USB Type-C port rated 65W PD for charging a laptop during presentations.

What networking options does it include?

It offers Wi-Fi 6 on 2.4 GHz and 5 GHz, Gigabit Ethernet (1000M) through two RJ-45 ports, and Bluetooth 5.2. Wired Ethernet suits classrooms and offices that receive content from a central network, while Wi-Fi 6 suits rooms without fixed cabling. Confirm your network design with the SmartRooms Qatar team before installation.

Which wall mount does it need, and how heavy is it?

It is specified for a VESA 400 x 200 flush wall mount. The product weighs 57.54 lbs and measures 50.04 x 30.47 x 3.43 inches, so the wall and fixings should be checked before fitting. SmartRooms Qatar offers professional installation and free site surveys for wall-mounted panels across Qatar.

Will it work on Qatar's 240 V mains supply?

Yes. The power requirement is 100-240V AC at 50-60 Hz, which covers Qatar's 240 V, 50 Hz supply. Typical power consumption is 160 W and the maximum is 320 W. Plan a dedicated socket near the mounting point, and confirm cable routing during the site survey.

Is it suitable for a classroom in a school in Al Wakrah?

It can suit a classroom where pupils sit close to the screen, and the 55-inch 4K image helps with reading text, diagrams and maps on the board. Schools in Al Wakrah, Al Rayyan or Doha fitting out several classrooms can order against a purchase order. Each wall should be surveyed first, because the mount needs a flat, sound surface.

Can it serve a huddle room in a West Bay office where teams work in Arabic and English?

A West Bay huddle room where a team switches between Arabic and English documents is a good fit for the two HDMI inputs and the built-in Android environment. The source data does not state Arabic language support for the on-screen software, so confirm the language settings you need with SmartRooms Qatar before ordering.

Can it be placed near a window or in a lobby during the summer?

The source data does not give an operating temperature range for this model, so confirm the environment with the SmartRooms Qatar team before installation. Avoid positions in direct sunlight on glass frontages, and avoid lobbies exposed to dust storms. Indoor, air-conditioned rooms with stable temperatures are the simplest setting to plan for.

What warranty comes with it, and how do I request a quote?

The unit carries a 3-year standard warranty, with options for an advanced hardware warranty or an extended warranty. To request a quote, send SmartRooms Qatar the room size, the wall type and whether you need LPO or tender paperwork. Quotations are usually issued within one working day, and a site survey can be arranged before installation.
