Front glass is now standard for PCAP touch screens. The high quality material can be customized and refined through various manufacturing processes.

Glass is the highest quality surface material. It provides a premium look and can be customized to exact required specifications through various production processes. Glass also offers protection for applications frequently exposed to vandalism. It is very sanitary and resistant to most cleaning solutions.

Glass offers numerous possibilities but it is important that all potential features and influences are considered. We have compiled frequently used technical terms as well as relevant information and explanations below.

Float glass

The term refers to the manufacturing process (float glass process) of sheet glass. Approximately 95% of sheet glass is now produced using this method. The molten glass is poured into a tin bath, continuously floating and spreading out evenly. The surface tension of the liquid glass and tin create very even surfaces. After the material has solidified and cooled down in an annealing lehr, the glass is cut into requested shapes and sizes.

This glass is the basic material for our capacitive controls. Through various processing steps, it can be modified according to customer requirements including anti-glare properties and tempered glass.

Gorilla Glass

This is brand name by a U.S. manufacturer. It is basically a thin sheet glass with a chemically strengthened surfaced. It features a high break and scratch resistance and is currently primarily used in smartphones.

Specific characteristics

For certain areas of application, the front glass has to fulfill specific requirements such as scratch resistance or conductivity. For this purpose, the base material “float glass” can be customized and refined. The following technologies are available:

  • Single-pane safety glass
  • Laminated safety glass
  • Conductive glass (ITO or silver conductive paint)
  • Glass with anti-fingerprint coating
  • Glass with non-sparkling effect
  • Glass with mesh fabric or shatter proof film
  • Ceramic or organic printed glass (screen or digital print)
