High-brightness shop window displays: your ads visible at any time

The Barcelona LED 2-Screen Shop Window Kit (21.5" screens) is the digital signage solution designed for businesses that want to transform their shop window into a dynamic advertising medium. Its 2000 nits brightness , up to six times greater than that of a conventional television or monitor, ensures that photos, videos, and prices are clearly visible from the street, even in direct sunlight.

With a Full HD IPS panel , integrated Android 11 player , 24/7 operation and remote management from your mobile phone or the cloud, it replaces paper posters with always up-to-date ads, without printing or going to the store.

2000 nits with intelligent automatic brightness

A typical home screen emits around 300 nits and is barely visible from the outside in daylight. These high-brightness shop window displays reach 2000 nits , the recommended level for sun-facing shop windows. Their automatic brightness control adjusts the brightness to the ambient light to keep the image visible at all times and reduce energy consumption when full power isn't needed.

Industrial panel that does not darken in the sun

Conventional televisions go black when the sun heats the screen (above about 75°C). This display uses an industrial-grade LCD panel resistant to temperatures up to 110°C and high-temperature-resistant optical materials that do not warp with sun exposure. The anti-glare coating and 178° viewing angle ensure a clear image from anywhere on the sidewalk.

Clean and customizable hanging installation

The screens are suspended from the ceiling by steel cables with adjustable height , and the power cable is integrated into the suspension for a clean, cable-free finish. Their ultra-thin design (40 mm deep with a 15 mm frame) allows multiple screens to be stacked in columns or positioned horizontally.

2-screen kit for a more complete shop window

The kit includes two 21.5" displays to create an attractive layout: show multiple properties at once, a promotional video alongside the price list, or different services side-by-side. The installation can be expanded with additional units and managed from the same platform.
