SCHOTT Xensation® Cover ITS

Chemically strengthened alumino-silicate glass sheets for innovative integrated touch solutions

Xensation Cover AG ( anti-glare)
Xensation® Cover ITS is produced using SCHOTT‘s unique microfloat process.
Having firmly established Xensation® Cover as the world‘s strongest alumino-silicate glass for conventional touch sensor technologies, SCHOTT is proud to offer the same outstanding cover glass performance characteristics now adapted for the rapidly emerging integrated touch technology market, facilitating the combination of touch sensor and cover glass into
one while maintaining an impressive level of mechanical and optical performance.
OGS technology enables touch panel or display makers to offer lighter and thinner touch solutions while at the same time reducing the complexity of the process chain.
Xensation® Cover ITS (Integrated Touch Solution) is now available as a full sheet, ion-exchanged specialty glass that enables integrated touch through TCO deposition on large glass sheets. The performance benefits of Xensation® Cover ITS support the design and implementation of innovative, next generation devices using integrated touch technologies such as One-Glass-Solution (OGS) with an unprecedented level of durability and reliability. This enables touch panel makers to offer lighter, thinner touch module stacks as well as reducing the complexity, and enhancing the efficiency, of their process chains.

Key benefits of Xensation® Cover ITS

  • Outstanding impact strength enables integrated touch modules with excellent damage resistance and reliability.
  • High scratch resistance and tolerance for superior aesthetic appeal and durability.
  • Custom-sized ion-exchanged sheets designed for easy and efficient cutting using industry standard equipment.
By designing special ion-exchanged, full glass sheets that can be easily and efficiently cut after ITO sensor deposition, SCHOTT enables touch panel manufacturers to produce lighter, thinner touch modules protected by the strongest cover glass available on the market today.

Xensation® Cover ITS - bringing unprecedented durability and reliability to the industry’s most innovative integrated touch-based devices.
