The OBFILM425-110 is a versatile 42.5″ interactive touch film engineered for mid-size commercial and public-facing displays. Delivering enhanced 110P sensitivity for responsive touch performance, it transforms ordinary glass, acrylic or LCD surfaces into a clean, edge-to-edge multi-touch interactive screen without overlay bezels, making it ideal for museum exhibits, self-service kiosks and collaborative walls. Built on dual PET layers with criss-crossed nanowire grids forming a nano-capacitive sensing matrix activated by finger contact, the film offers under-2mm touch accuracy, under-2.5ms response time and over-90% light transmission for crisp, vibrant visuals. Optimised for mid-size commercial touch applications and typical shop-window glass, it supports glass installations up to 8mm cover-glass thickness. Compatible with rear projection, Obeytouch Adhesive Screens and standard LCD monitors, the film adheres to the back side of glass walls, shop windows or display enclosures and connects via USB or RS232 controller (driver confirmation required on non-Windows platforms). It supports up to 20 simultaneous touch points and works with Windows, Linux and Android. Because no external components sit on the window surface, the installation remains 100% safe and vandal-proof while preserving a fully transparent, unobstructed view. Supplied with a matching controller board, cabling and installation guide, and CE/CB/EMC certified, the film is widely used as the input device for consumer electronics and all-in-one touch computers.
