Indium tin oxide is the most widely used transparent conductor material for optoelectronic applications, but it is currently limited by high cost and inadequate performance. This will address the performance and cost issues in the transparent electrode of large-area optoelectronic applications such as touch sensors, displays, and organic light emitting diodes (OLEDs) by the development of a new metal-patterning technique that prints high-performance metal grids directly into glass and plastic.


Electroninks' new high-performance, particle-free metal inks are being used to create metal-grid transparent conductors. These high-performance grids may allow brightness uniformity and flexibility in large-area OLED devices and may also contribute to advancements in displays, touch panels, electrostatic discharge (ESD), and electromagnetic-interference (EMI) and RF shielding.
