LED screens for schools and assembly halls

An LED screen for a school, university or college assembly hall is the request KazLedPro receives more often than any other. The screen replaces the projector on stage: it is visible with the lights on, needs no blackout and works the same for morning assemblies, graduation, lectures and parent meetings. We have been building LED screens in Almaty since 2012, install with our own crew and keep a module warehouse from which warranty parts are replaced.

Our portfolio includes more than fifteen educational institutions across Kazakhstan: gymnasiums 130, 132, 133 and 153 in Almaty, schools in Karaganda and Taldykorgan, the private Shokan Ualikhanov school, Almaty International School, Tien Shan International School, KIS and NGS, the Nur-Mubarak, Yasawi and Zhubanov universities, and the Academy of Logistics and Transport. Most bought the screen through public procurement, and we know how to write a specification so the tender is not re-run.

Below: how to choose the pitch and size of an LED screen for the depth of the hall, what the school needs to prepare in terms of power and stage, how a laptop is connected, and what domestic-manufacturer status gives in procurement. A preliminary estimate can be calculated on the website by screen width and height.

Which screen an assembly hall needs

Pixel pitch is chosen by the distance to the front row. A simple rule: the pitch in millimetres roughly equals the minimum viewing distance in metres. If the front row is three metres from the stage, P3 is enough; if the audience sits two metres away or it is a lecture theatre with small-print presentations, P2.5 is used. In Almaty gymnasiums in 2021 we installed P4 built from 256×256 mm modules with viewing from four metres — enough for a hall of 200–300 seats, and noticeably cheaper than fine pitch.

Size is calculated from the stage, not from the budget. Width follows the stage opening minus the wings, the bottom edge sits above the heads of the front row, and the 16:9 ratio lets presentations and video run without black bars. Indoor models have no fans, so nothing hums in the hall during performances.

• P2.5, 320×160 mm module — viewing from 2 m, brightness 350–550 cd/m², for lecture theatres and small halls.
• P3, 320×160 or 192×192 mm modules — viewing from 3 m, the standard choice for a school stage.
• P4, 256×256 mm module — viewing from 4 m, the economical option for large halls; gymnasiums 130, 132, 133 and 153 are built this way.
• P2.6 and P2.9, 500×1000 mm cabinets — 1,000 cd/m², 13 kg per cabinet; when the screen must be taken down and moved to events.
• Outdoor P5–P10 for a facade or sports ground — as at Zhubanov University in Aktobe.

Public procurement and the domestic manufacturer registry

Schools and universities buy screens through goszakup.gov.kz, and what actually arrives depends on how the specification is written. We help draft the technical specification before the tender is announced: we survey the stage and hall, calculate resolution, brightness, power and weight, describe characteristics that can be verified at acceptance, and provide an estimate for budget planning.

KazLedPro is listed in the registry of domestic manufacturers and holds the KTP industrial certificate. For the buyer this is a lawful preference: a conditional discount on our bid price and priority under domestic-producer support rules. We submit the bid with the full package — certificates of conformity, KTP documents, warranty obligations, a record of similar school deliveries. After the award: delivery, installation, commissioning, training, acts and the screen passport. Warranty is 2–5 years depending on the model.

Laptop connection and everyday use

The screen connects to a laptop over HDMI through a video processor and behaves like a second monitor: presentations, video, a live camera feed at graduation, an online lesson. A dedicated computer is not required — any teacher's laptop will do. A schedule can be set so the screen switches on before the first lesson and off after the last one.

After launch we train the facilities manager or the IT teacher: how to upload a video, switch the source, what to do if the screen does not turn on. Service is from the front — a module comes off its magnets without dismantling the stage. Schools often order stage lighting on a truss together with the screen: this was done at gymnasiums 132, 133 and 153 and at NGS school. Light, sound and screen come under one contract and one acceptance act.

Schools and universities where our screens already work

Every site is in the portfolio with photos, and the Shokan Ualikhanov school and KIS also have video testimonials. You can call any of them and ask how the screen is doing several years on.
