Terms,
precisely explained.

An LED wall is a modular screen made of thousands of individual light-emitting diodes that is self-illuminating without backlighting, enabling higher brightness and more flexible formats than an LCD display.

Kiosk systems are standalone interactive terminals with touchscreens that provide self-service functions in public or semi-public environments – from ticket purchases and ordering to check-ins.

COB (Chip-on-Board) is an LED packaging technology where the individual LED chips are bonded directly onto the substrate and covered with a protective resin layer — it enables finer pixel pitches, higher robustness, and wider viewing angles than older SMD technology.

MicroLED refers to self-emissive displays made of microscopically small inorganic LEDs (edge length < 100 µm) that provide deep blacks, extreme brightness, and a very long service life without burn-in, all without backlighting or organic OLED materials.

An outdoor display is a screen engineered for permanent outdoor use with an IP protection rating (at least IP65), high-brightness panel (≥ 2,500 nits), active climate control, and UV-stable materials — built for years of 24/7 operation in wind, rain, frost, and sun.

Transparent LEDs are LED modules with high light permeability (typically 65–90%) that display image content on glass surfaces, shop windows, or architectural facades without completely blocking the view through the surface.

A touch table is a horizontally installed multitouch screen (typically 43–86 inches) with toughened glass, designed for multiple simultaneous users in workshops, showrooms, museums, and conferences.

Pixel pitch refers to the distance between the centres of two adjacent pixels on an LED wall in millimetres and is the most important metric for image sharpness, minimum viewing distance, and investment costs.

Smart Glass is a glass pane with an embedded film whose transparency can be electrically switched between milky-opaque and crystal-clear — within fractions of a second and without any mechanical components.

PDLC (Polymer Dispersed Liquid Crystal) is the most widely used smart glass technology, in which liquid crystals dispersed in a polymer matrix allow light to pass through when AC voltage is applied and scatter it when no voltage is present.

Nits (cd/m², candela per square metre) are the SI unit for the luminance of a display — they describe how much light a screen surface emits in a specific direction and are the decisive metric for readability under various ambient lighting conditions.

A Digital Signage CMS is the central software used to create, schedule, distribute content to locations, and monitor the status of a screen network — typical examples include easescreen, BrightSign Network, OptiSigns, Samsung VXT, and Lumiplan.

Digital signage refers to centrally controlled display networks in public or semi-public spaces that broadcast content in a location-specific, time-controlled, and data-dependent manner via a Content Management System (CMS).

DOOH (Digital Out-of-Home) refers to ad-financed digital screens in public spaces whose advertising slots are marketed with second-by-second precision, data-driven, and increasingly programmatically via platforms such as Vistar, Hivestack or Broadsign.

Wayfinding refers to digital or analogue guidance systems that help orient people in complex buildings or public spaces — from railway departure boards to interactive hospital touch kiosks.
