Overview

The OneScreen Touchscreen TL7 Education 55 is a 55-inch 4K UHD interactive display for classrooms and small meeting rooms. Its 40-point zero-bonding infrared touch layer has 1.5 mm accuracy, and it runs Android 11 with 8 GB RAM and 64 GB storage. An OPS slot and USB-C with 65W power delivery suit Qatari schools, training centres and compact boardrooms.

A 55-inch 4K panel sized for close-range teaching

The TL7 Education 55 is a 55-inch LED interactive display with 4K UHD resolution (3840 × 2160) in a 16:9 format. Brightness is rated at 400 cd/m², the viewing angle at 178°, and the refresh rate at 60Hz. A blue light filter and an ambient light sensor that adjusts screen brightness are built in, and displayed colours reach 1.07 billion through 10-bit processing. The size suits a standard classroom or meeting table where viewers sit close enough to read fine detail.

Touch, processing and software

Touch uses zero-bonding infrared technology (Gen 2) with 40 touch points, an accuracy of 1.5 mm and a response time under 7 ms. The panel runs Android 11 on a quad-core ARM Cortex A55 processor (up to 1.8 GHz), with 8 GB RAM and 64 GB storage. The series software includes OneScreen Write for annotation, OneScreen Central for managing panels from one place, and LearningHub and QuizWiz for lessons. The glass has a Level 7 MoHS anti-glare, anti-fingerprint finish, and two stylus pens with anti-bacterial coating are supplied.

Ports and connectivity for everyday lessons

Side: 2x HDMI-In, 1x HDMI-Out, 1x VGA-In with VGA audio input, 1x RS-232, 2x RJ-45, 2x USB 3.0, 1x USB 2.0, 3.5mm audio output and an OPS PC slot.
Front: 1x HDMI-In, 1x USB touch port, 2x USB 3.0 and 1x USB Type-C with 65W power delivery.
Wireless: Wi-Fi 6 (2.4 GHz and 5 GHz), Gigabit Ethernet and Bluetooth 5.2.

The front connections suit a teacher who arrives with a laptop and needs to connect quickly. The OPS slot lets a school add a computer module instead of running a separate PC.

Planning the installation in Qatar

Plan the wall before the panel arrives. The standard mount is a VESA 400 x 200 flush wall mount. The panel weighs 57.54 lbs net and 75.95 lbs shipping, so two people should handle it. Power is rated 100 to 240 V AC at 50 to 60 Hz, with typical consumption of 160 W and maximum of 320 W, a range that covers Qatar's 240 V, 50 Hz mains. The source data for this model does not give an operating temperature range, so confirm room conditions with the SmartRooms Qatar team before mounting it near sun-facing windows or in spaces without air conditioning.

Where it fits in Qatar

A primary school in Al Sadd or Al Rayyan fitting out classrooms where teachers annotate lessons and play video on the same screen.
A training centre in the Industrial Area running short technical courses, with a laptop connected at the front of the panel.
A company meeting room in West Bay or Msheireb where a small team reviews documents, and a 55-inch screen keeps the room compact.

Questions about Touchscreen TL7 Education 55

Who is the TL7 Education 55 designed for?

It suits classrooms, breakout rooms and small meeting spaces where a 55-inch screen is the right size. The 4K UHD panel in a 16:9 format shows text, maps and video clearly, and 40-point touch lets teachers write directly on the screen. Schools in Doha, Lusail and Al Khor often choose this size for one display per room.

How does the 55-inch model differ from the 65-inch and 86-inch versions?

Each size has its own panel and wall mount. The 55 uses a VESA 400 x 200 flush wall mount, the 65 uses 600 x 400, the 75 uses 800 x 400 and the 86 uses 800 x 600. Typical power draw is 160 W for the 55, compared with 200 W for the 65, so the smaller model is easier to fit into classroom power budgets.

What touch technology does it use and how accurate is it?

It uses zero-bonding infrared touch (Gen 2) with 40 touch points, 1.5 mm accuracy and a response time under 7 ms. Two stylus pens with anti-bacterial coating are included. The 1.5 mm figure matters when a teacher writes small labels or draws diagrams in a maths or science lesson.

Which devices can I connect to it?

On the side there are 2x HDMI-In, a VGA-In with audio input, HDMI-Out, RS-232, two RJ-45 ports, USB 3.0 and USB 2.0 ports and an OPS PC slot. On the front there is an HDMI-In, a USB touch port, two USB 3.0 ports and a USB Type-C port with 65W power delivery, useful for a teacher's laptop at the start of a lesson.

Does it run Android, and which software comes with it?

Yes. It runs Android 11 on a quad-core ARM Cortex A55 processor (up to 1.8 GHz) with 8 GB RAM and 64 GB storage. The series software includes OneScreen Write for annotation, OneScreen Central for managing panels from one place, and LearningHub and QuizWiz for lessons. Confirm app availability with SmartRooms Qatar before ordering.

Can it support Arabic and English lessons in one school?

The source data for this model does not list language options, so ask SmartRooms Qatar to confirm Arabic menu and keyboard support before ordering. The data does confirm the 4K display, Android 11, Wi-Fi 6 and Bluetooth 5.2, which matter to schools that teach in both languages and share one display across subjects.

Is it suitable for a classroom in Doha where the wall faces the afternoon sun?

Choose a wall away from direct sun and glare. The panel has a Level 7 MoHS anti-glare, anti-fingerprint surface and an ambient light sensor for adaptive brightness, which helps, but the data does not list an operating temperature range. Ask SmartRooms Qatar to confirm the room conditions before mounting on a sun-facing wall.

Does the power supply suit Qatar mains?

Yes on voltage and frequency. The panel is rated 100 to 240 V AC at 50 to 60 Hz, which covers Qatar's 240 V, 50 Hz supply, with typical consumption of 160 W and maximum of 320 W. Confirm that the supplied power cable's plug fits BS 1363 (Type G) sockets in your room before installation.

How heavy is it and what do I need for wall mounting?

The panel weighs 57.54 lbs net and 75.95 lbs shipping, so two people should lift it. It uses a VESA 400 x 200 flush wall mount pattern. A site survey, which SmartRooms Qatar offers free, can check the wall structure and mounting plan before drilling in a school or office in Al Rayyan, Lusail or Msheireb.

What warranty and certifications come with it?

The panel has a 3-year standard warranty, with options for advanced hardware or extended warranty. Listed certifications are RoHS and FCC. Products are covered by the manufacturer's warranty, and SmartRooms Qatar can confirm which warranty option is included in your quotation.

How do government bodies or schools buy several units?

Multi-room projects are usually bought on a purchase order (LPO) or through government tenders, including Monaqasat. SmartRooms Qatar can issue one quotation covering all 55-inch units, with each unit's accessories listed: HDMI cable, power cable, USB touch cable, Type-C cable, two stylus pens and a remote. Payment by bank transfer, cheque or purchase order is accepted.
