ITO on PET

Patterned ITO

Sheldahl offers value-added processes to compliment our Sheldahl® brand Indium Tin Oxide (ITO) coated polyester film products. This includes the ability to pattern ITO and print ink circuitry which is done in a highly efficient, hands-off roll-to-roll format. Patterned ITO is ideal for Multi-Touch or extremely high node densities, and preferred for applications where maximum clarity is desired

Typical applications for Sheldahl’s patterned and printed ITO film include: projected capacitive touch sensors, transparent capacitive switches, flexible displays, and flexible photovoltaic solar cells.
