The 43″, 55″, 65″ and 84″ versions are equipped with infrared optical touch technology while the 84″ version with capacitive touch technology, following a brief explanation of the differences. The two types of touch most used in the world of Digital Signage, are the Capacitive and the Optical. The operation of a capacitive touch screen is based on a glass coated on the inner side by conductive layers that, from the moment in which the fingertip occurs (or any conductive object), it senses an alteration of the electric field. This alteration is immediately detected and managed by the management software which assigns the coordinates of the touch.

The advantages of this technology are represented by the maximum protection of the glass layer that protects the technology and guarantees greater resistance to wear over time. Another advantage of these touch devices is the remarkable simplicity of use due to the excellent sensitivity of these displays that do not require strong pressures to operate but only need a slight touch. Unlike optical touch screens, it is immune to changes in ambient light, allows the detection of the amount of pressure on the touch and allows the creation of devices with all-flat shapes.
