Projective Capacitive Touch Technology 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 (also latex gloved) & stylus-pen. IPS Technology IPS technology offers higher contrast darker blacks & much better viewing angles than standard TN technology. The screen will look good no matter from what angle you look at it. Ball-drop-test proof The ball-drop-test uses a half-kilo steel ball which is dropped onto the touch screen from a height of 1.3 meter. If the touch screen surface remains unaffected the monitor passes the ball-drop-test for high impact resistance & durability.IP65 The IP code classifies & rates the degree of protection against water intrusion. IP65 means that the monitor is protected to water splashes against the enclosure from any directio.
