The LG KT-T550 55-inch Touch Overlay Kit is a cost-effective, enterprise-grade accessory designed to instantly transform standard commercial displays into high-performance interactive hubs. Built specifically to fit compatible 55-inch LG Large Format Displays (LFDs), this overlay provides businesses across the UAE and GCC with a seamless upgrade path. Instead of replacing existing digital signage infrastructure, system integrators can deploy the KT-T550 to inject full multi-touch capabilities into meeting rooms, retail stores, and corporate lobbies.

Advanced Infrared Touch and Collaboration

Equipped with advanced Infrared (IR) touch sensors, the LG KT-T550 tracks up to 10 points of simultaneous contact with extreme precision. This multi-touch capability makes it an ideal addition to collaborative spaces where teams need to brainstorm, annotate documents, or navigate complex data interfaces together. The system architecture supports native multi-touch gestures—such as pinching, zooming, and rotating—ensuring a smooth, smartphone-like user experience scaled up to a massive 55-inch canvas.

Rugged Commercial Protection and Anti-Glare Glass

Engineered for heavy-use public and corporate environments, the overlay kit features a 3.0 mm thick tempered protection glass. This layer serves as a rugged shield, safeguarding the costly underlying LCD panel from physical damage, scratches, and daily wear-and-tear. To maintain pristine visibility under bright overhead office grids or showroom lighting, the glass is treated with an anti-glare coating. This treatment minimizes reflections while maintaining high light transmission, preserving the vibrant color accuracy and brightness of your existing display.

Streamlined Integration and Multi-OS Stability

The structural frame of the KT-T550 is designed to wrap tightly around the chassis of compatible LG display series, matching their aesthetics for a clean, integrated finish. Installation is exceptionally straightforward: the kit connects directly via a standard USB 2.0 interface. Because it draws power straight from the host USB bus, it entirely removes the need for extra power bricks behind the mount. The overlay provides extensive cross-platform compatibility, working plug-and-play with Windows, macOS, Linux, and Android operating systems to seamlessly fit into any corporate IT landscape.

No, the LG KT-T550 is a bus-powered device that connects to your media player or smart display via a standard USB 2.0 cable. It draws all necessary operational power directly through the USB port, completely eliminating the need for an external AC power adapter or extra wiring behind the wall mount.
No, the KT-T550 is precision-engineered to physically match the bezel dimensions, screw alignments, and depth profiles of specific LG commercial display series (such as the SE3B, SM5B, and UH5B lines). It cannot be reliably fitted onto standard consumer TVs or third-party monitors, as the physical alignment of the Infrared sensors must precisely match the screen's active matrix.
The overlay kit features high-grade optical glass with a light transmission rating of over 85%. While there is a microscopic reduction in raw brightness due to the physical protection layer, the integrated anti-glare treatment drastically reduces surface reflections. This ensures that text, maps, and UI elements remain perfectly sharp and legible under bright ambient lighting conditions.
For modern Windows operating systems, the overlay acts as a standard HID (Human Interface Device) compliant touch screen and is typically plug-and-play without manual calibration. For specialized layouts, portrait installations, or multi-monitor configurations, a quick one-time alignment using the native Windows Control Panel or LG's utility software is recommended to ensure pixel-perfect tracking accuracy.
The KT-T550 is built with a heavy-duty 3.0 mm tempered glass overlay designed specifically to withstand high-traffic commercial environments. It protects the fragile underlying LCD panel from scratches, impacts, and heavy finger pressure. The surface can be safely cleaned using standard industrial electronic microfiber cloths and light isopropyl alcohol solutions to maintain hygiene in public spaces.
