Both GFF and GG structured PCAP touch screens have cover glass on top of the touch sensor with OCA (Optically Clear Adhesive) in between.
- The GFF touch sensor has two layers of films stacked together with OCAs in between.
- The GG touch sensor uses a double sided ITO glass.
Protective films are provided underneath the touch sensor. Below shows an illustration of the two different structures and lists of some of our standard touch screen sizes. Please note that the PCAP touch screen is the top cover of the interactive display device, very often with specific technical requirements and aesthetic preferences. Please contact us for your specific project needs. 
For VT-A series GFF touch screens: TS=0.425mm, TUO=0.125mm, TUF=0.125mm, TBO=0.05mm, TBF=0.125mm.
