Substrates are used to provide rigidity to resistive touchscreens. A two layer resistive touchscreen design has a conductive glass substrate which provides both rigidity and electrical functionality. A three layer design may use a rigid glass or a plastic substrate to provide support.
TPI offers substrates made of glass, polycarbonate, acrylic and other plastics. These substrates are available in a wide range of thicknesses and properties.
Standard glass is used in cost sensitive commercial applications. Chemically strengthened and heat tempered glass provide superior strength compared to untreated glass. Strengthened glass substrates are suitable for industrial and military applications where a touchscreen’s mechanical strength and durability is a must. Thermal and dimensional stability of glass makes it a suitable substrate where touchscreens need to operate in a wide range of environmental conditions.
Standard and strengthened glass substrates are available in the following standard thicknesses in both conductive and non-conductive versions:
- 0.04″ [1 mm]
- 0.06″ [1.5 mm]
- 0.08″ [2 mm]
- 0.093″ [2.36 mm]
