Touch technology – capacitive This technology uses a sensor-grid of micro-fine wires integrated into the glass that covers the screen. Touch is detected because electrical characteristics of the sensor grid change when human finger is placed on the glass. Thanks to the glass overlay this technology is highly durable, & the touch function remains unaffected even if the glass is scratched. It offers perfect picture performance & will work with human finger (gloved or not) & magnetic ball. IP54 The IP Code classifies how resistant a device is to foreign objects & moisture. IP54 means that the monitor will operate in dusty conditions & will resist splashing water. Scratch resistance Scratch resistance is essential for touch solutions used in public places & schools. This is achieved thanks to a glass overlay covering the screen. It guarantees high durability of the touch function & even more importantly the touch function remains unaffected even if the glass is scratched. VESA VESA mount compliance means you can easily mount the LFD to any mounting that complies with the VESA standard.
