LED screen for a shop window: purchase with installation, readable in sunlight

Short answer: which LED screen for a shop window

For a shop window that gets sunlight, you buy a complete screen from us with ICON 3.9 IP cabinets: 4,500 nits of brightness and a 3.9 mm pitch, readable from 4 m. ICON 2.6 has 800 nits and is meant for indoor spaces without sun, so in a sunlit window it loses to daylight. We install and service in Warsaw and across Poland.

This is a solution for large shop windows: the manufacturer's minimum order is 8 cabinets, i.e. 2 m² (e.g. a 2 × 1 m screen), and viewers should stand at least 4 m from the glass. For a small window with customers right at the glass, a modular LED wall makes no sense; that is a job for a high-brightness LCD display. For the 3–5 m band the configurator suggests ICON 2.9 Hybrid (4,000 nits, on request). The whole range is described on the FOS ICON LED screens page.

Brightness behind glass: why ICON 3.9 IP and not 2.6

Daylight and reflections in the glass eat up contrast. In industry practice, a sunlit shop window needs roughly 2,500–3,000 nits or more.

You adjust brightness in 256 steps, so after dark the screen does not dazzle passers-by, and the processor has a light sensor connector (automatic brightness). It can be warmer behind glass than outside: the ICON series operates up to +40 °C, and above 30 °C air conditioning is needed. Leave about 15 cm between the cabinets and the wall for cooling; we discuss summer temperatures in the window during the site survey.

Distance from the pavement: pitch and resolution

For ICON 3.9 IP the FOS viewing distance is 4 m, and the configurator selects this model for viewers further than 5 m away. Below 3 m the pixel grid shows, because the finest pitch for a bright shop window is 2.9 mm; we discuss such locations individually. Resolution depends on the screen size (128 × 128 px per cabinet):

That resolution suits a logo, a price, a promotion or a short video, not small text; prepare content at the screen's resolution.

Installation in a shop window: a permanent screen

The cabinet measures 500 × 500 × 83 mm and weighs 8 kg (32 kg of panels per m²). Dimensions grow in 0.5 m steps, and FOS supplies cabinets in flight cases of 8. We design the frame or the wall, floor or ceiling mounting after the site survey: we check the load capacity of the substrate, service access and power points. Service is done from the front, so the installation plan leaves access to the modules. Installation is carried out by qualified technicians.

Before ordering, check the rules for shop window advertising with your local municipal office, agree the installation with the owner or manager of the premises, and in a listed building consult the heritage conservation officer.

Power and control

A 2 × 1 m screen (2 m²) draws up to 1.2 kW of maximum power (600 W per m²), i.e. about 5 A at 230 V; we always design the power supply for maximum power. The picture is driven by a NovaStar VX600 Pro processor with HDMI, SDI and USB 3.0 inputs: the screen plays from a computer, media player or flash drive, and settings are retained after a power cut.

How much does a shop window LED screen cost

We price the complete set, not just the panels. According to the configurator (ICON 3.9 IP, viewer at 6 m, your own truss; net prices from the VEX catalogue, 13 October 2026), a 2 × 1 m screen costs about 46,000 PLN net, and a 3 × 1.5 m screen (18 cabinets, 768 × 384 px) about 65,000 PLN net. The price includes cabinets with spares (5%, minimum 2 cabinets, topped up to a full case of 8), a NovaStar processor, power, flight cases and ICON Led Clamp clamps for your own truss or pipe (Ø 42–58 mm). The processor is a fixed cost: for the smallest screen it is just under a fifth of the total.

The shop window frame, site survey, installation and commissioning, data cabling and delivery are priced separately. More examples: How much does an LED screen cost.

How to buy from us: configurator, survey, design, installation

• 1. Configurator. You price the screen to scale and get a net price and a PDF sheet; we reply to enquiries within 1 business day.
• 2. Site survey: 600 PLN net. We measure the shop window and power points; the fee is credited towards the project.
• 3. Design and offer. We select the model, frame, power and processor; the screen is ordered from the manufacturer for your project.
• 4. Installation and commissioning: from 3,800 PLN net. We set up the screen, connect it and calibrate colour and brightness across the cabinets.

We sell to businesses with a Polish tax ID (NIP) on a VAT invoice; 23% VAT is added to net prices. We sell screens for ownership and install them permanently; we do not offer rental.

Service and support: one partner from delivery to inspection

We take responsibility for all of it: selection, delivery, installation and service. The power supply, receiving card and HUB card form a replaceable 3-in-1 power box, and the 250 × 250 mm modules are universal. The cabinets have a 2-year (24-month) manufacturer's warranty, after which we provide post-warranty service and replacement of individual modules. The installation should be inspected at least once a year. Installation and delivery are described on the LED screen installation page.
