AGC Glass Europe develops TIREXtreme glass for multi-touch screens

The Belgian manufacturer wants to respond to the growing demand for touch coverage screens with FTIR technology with this multi-touch infrared sensing glass for screens larger than 20 inches and up 120.

TIREXtreme incorporates innovative infrared multi-touch sensing technology developed by ACG Glass Europe for screens larger than 20 inches or transparent structures that, although it has the same aesthetic properties as colorless glass, It has an infrared absorption of almost thirty times more than colorless float glass thanks to its special composition.

This technology is based on infrared transmitters and receivers arranged around the edge of the glass., so that the infrared light travels through the glass in an upward and downward direction by transverse reflection. Any contact with the glass surface (like the pressure of a finger) generates a disturbance that the receiver detects and, therefore, activate the system.

For this, the glass must have high infrared transmission power. Regarding the most adopted capacitive technology for smartphones and tablets of less than 20 inches, Infrared internal reflection makes it possible to create multi-touch systems with touch screens. 15 a 120 inches at an affordable price.

This is a solution especially suitable for manufacturers who want to take advantage of FTIR technology., which allows touch pressure to be detected more accurately and offers a better appearance, less vulnerability to scratches and greater compaction than conventional IR technologies, in which you usually have to place an infrared frame in front of the screen.

In addition to this multi-touch technology, TIREXtreme is an ideal material for applications that require a transparent substrate with high transmission power in the near-infrared spectral region.. The glass is sold in thicknesses between 0,55 y 4 mm. (with dimensions up to 3.21x 6 m.) and maintains its properties even when it goes through manufacturing processes such as bending or tempering (chemical or thermal).
