Indoor LED screens

Indoor LED screens are models with pixel pitch P0.93–P4 and brightness of 350–1,000 cd/m²: they are viewed from one to four metres with the lights on. The KazLedPro catalogue has 15 indoor models: 640×640 and 500×1000 mm cabinets, 320×160, 256×256 and 192×192 mm modules, and a P0.93 COB cabinet for studios and situation centres. We assemble the screens in Almaty and install them with our own crew across Kazakhstan.

This kind of LED screen is bought for meeting and conference rooms, school and university assembly halls, TV studios, receptions and retail floors. Since 2012 we have delivered indoor screens to dozens of schools, hotels, banquet halls and government institutions; case studies with photos are in the portfolio. Below: how to choose the pitch for your room, how COB differs from SMD, and why a screen replaces a projector and a panel video wall.

Which pixel pitch your room needs

Distance in metres roughly equals pitch in millimetres, so start from the nearest viewer. A meeting room where people sit two to three metres from the wall — P1.53–P2: the 640×640 cabinets pack 422,500 and 250,000 pixels per m², with no visible grain. A conference room or school assembly hall at 6–10 m — P2.5–P3, the most common choice in our projects: P3 screens totalling 100 m² at the I. Zhansugurov Palace of Culture in Taldykorgan (2023), P2.5 at Almaty International School (2022). A gym or lobby viewed from four metres and beyond — P3.91 or P4: that is how the screen in the assembly hall of Gymnasium No. 130 in Almaty was built (2021).

TV studios and situation centres take a fine pitch with a refresh rate from 3,840 Hz so there is no banding on camera: P0.93 at the Dubai Police command centre (48 m², 2023), P1.53 at the ENOC situation centre (20 m², 2022), P2 at the Eurasia TV studio in Astana (2021).

COB and SMD, cabinet and module

Most indoor models use SMD LEDs: each pixel is a separate package with three chips soldered to the board. It is a proven technology for P1.53 and coarser. The P0.93 cabinet is built differently — COB: the chips are encapsulated in compound and the front surface is solid, with no protruding packages. Such a screen tolerates touch and cleaning, gives an even black and works from one metre away while drawing 300 W/m² at peak and 100 W/m² on average.

The 640×640 mm cabinets, 65 mm deep, assemble into 16:9 and 21:9 formats, weigh 12–16 kg and are serviced from the front: a module comes off on magnets, so the screen sits flush against the wall with no recess. The 500×1000 mm cabinets are brighter (900–1,000 cd/m² for P1.95–P2.9) and suit halls with large windows; the 62 m² screen at the Aksai House of Culture (2021) is built from them. The 320×160 and 256×256 mm modules go where a precise fit to the opening matters or the budget is tight.

• P0.93 COB, 600×337.5 mm cabinet: studios, control rooms, home cinema.
• P1.53–P2.5, 640×640 mm cabinets: meeting rooms, receptions, showrooms.
• P1.95–P3.91, 500×1000 mm cabinets: brightly lit halls, stages, rental.
• P2.5–P4, 320×160, 192×192, 256×256 mm modules: assembly halls, gyms, lobbies.

Instead of a projector or an LCD video wall

A projector in a meeting room needs blackout and a lamp that dims over time; an LED screen with 350–550 cd/m² reads in daylight from the windows and has no consumables. That is how the screen in the conference hall of the Holiday Inn Almaty hotel (2025) is set up: presentations and meetings run without curtains and without warm-up. A panel video wall is divided by seams and limited by the panel size; an LED screen is a continuous canvas of any format, and a failed module is swapped on site in minutes.

The screen connects like an ordinary monitor: a laptop over HDMI through a video processor, wireless presentation, video conferencing. Indoor models run without fans, so nothing hums in the meeting room or on a recording. Operating temperature is −20…+40 °C (up to +50 °C for the 500×1000 series), ingress protection IP24–IP40 — enough for dry rooms.

What the supply includes and how we deliver across Kazakhstan

An indoor screen supply includes modules or cabinets with power supplies and receiving cards, a video processor sized to the resolution with spare ports, cabling, a wall frame or structure for your opening, installation by our own crew, commissioning with brightness calibration, operator training and documents: a screen passport with serial numbers, a wiring diagram, acts and a 2–5 year warranty card. Before installation the customer receives our electrical specification.

We ship from our Almaty warehouse; across Kazakhstan the equipment travels by freight company or in our own vehicle with the crew — that is how screens reached schools in Karaganda and Taldykorgan and a university in Turkestan. The exact set, timing and delivery cost are fixed in the contract after a survey or from your photos and dimensions.
