LG Touch Overlay Kit 55-Inch 10-Point IR Multi-Touch

The LG KT-T550 is a 55-inch infrared touch overlay kit that adds interactive capability to existing LG displays or compatible large-format screens. The 10-point multi-touch system enables multiple simultaneous inputs across the display surface, essential for collaborative work in education and corporate environments. Infrared (IR) touch technology requires no calibration and works through protective glass or anti-glare overlays without loss of image clarity.

Touch response time measures 9 milliseconds for single-point input and extends to 15 milliseconds for 10-point simultaneous contact—fast enough for interactive presentations and real-time applications. Touch accuracy remains within 1 millimeter across the full surface. The kit includes aluminum mounting brackets and anti-glare glass optimized for the 55-inch form factor. Operating conditions are 0 to 40 degrees Celsius and 10% to 80% relative humidity, covering standard office environments and classroom spaces. Weight is 9.7 kilograms.

Ideal for: Interactive classrooms, corporate presentation spaces, and control room monitoring stations where a standard display must become touchscreen-enabled.
