Product Overview

The LG LAT140GT82 is a 14 mm pixel-pitch transparent LED film that adheres directly to glass for see-through digital signage. With 53% transmittance, it lets the view behind it remain visible while displaying content, and reaches up to 2,100 nits for storefront-grade visibility. The self-adhesive film mounts without complex construction and supports curvatures up to 2,000R concave and convex. It runs LG's webOS smart signage platform.

Product Description

This LAT-series film uses R,G,B 3-in-1 SMD LEDs at a 14 mm pitch with 53% transmittance, allowing it to blend into existing glass facades and windows while remaining transparent when off. Brightness is rated up to 2,100 cd/m² with a 100,000:1 dynamic contrast ratio, and the LG Control Manager solution lets operators schedule brightness by timeline for optimal output through the day. The film is self-adhesive for direct application to window glass and can be expanded vertically or horizontally by adding more film, or trimmed to fit the install area. Connectivity includes HDMI, DisplayPort, DVI, USB, serial, and Ethernet. The webOS platform supports SCAP and is compatible with HTML, CSS, and JavaScript for web-based content development, while optional ConnectedCare provides cloud-based remote monitoring and fault diagnosis.
