Transparent Conductive Coatings For Glass

Coatings
#949 & #949 AR

General Description

ECI offers a variety of transparent conductive film designs for glass substrates. These films are commonly used for RFI/EMI shielding, static control, and liquid crystal display fabrication.

ECI #949 is an indium-tin oxide (ITO) coating that offers superior durability and excellent transmission in the visible region. The resistivity can be varied from less than 20 to over 10,000 ohms per square.

ECI #949 can be deposited through a mask to create patterns and combined with other films to meet specific requirements. Index-matching films can be deposited between the ITO and the glass substrate to attenuate internal back-reflections that can reduce contrast and overall transmission. Silicon dioxide overcoats can be deposited over the ITO to provide electrical isolation or enhanced durability.

ECI #949AR is a special low reflection transparent conductive design that offers first surface reflectivity of less than 0.5% across the visible spectrum and resistivity of less than 40 ohms per square. This design is used on displays and instrument windows that demand RFI/EMI shielding with excellent light transmission and contrast enhancement.

This family of films is extremely durable and stable under various temperature and humidity conditions. All coating designs meet or exceed the severe durability requirements of MIL-C-48497.
