Anti-static protection for in-cell liquid crystals and etc

Inorganic High-Resistance Transparent Conductive Films

Transparent films with a resistance greater than 1kΩ/sq have upturned conventional wisdom. Realized via Geomatec's unique technology that uses no organic material, the films also preserve durability

Overview

As a leading company in the field of transparent conductive films and ITO films, Geomatec has upturned conventional wisdom with transparent conductive films that are not only highly transparent but also have superior durability, thanks to our unique technology that makes no use of organic matter.
Contributing to in-cell liquid crystal touch screen displays for high-performance smart phones and more, our high-performance thin-film technology will continue generating breakthroughs for the entire globe and lead to better products for our customers.

Features & Strengths

Point1 Achieving transparent conductive films with high resistance of 1kΩ/sq without the use of organic materials

Although transparent conductive films have always been known for low resistance, Geomatec has used its knowledge of thin-film material development and world class skill with the sputtering method for film coating to eliminate the use of organic materials and increase resistance further.

Point2 Maintaining superior durability compared to one made with traditional coating methods

Traditional coating methods for transparent conductive films have use organic material, leaving a need for improvement in areas that affect reliability, such as surface hardness and resistance to heat. Geomatec solved this problem with unique technology that employs the sputtering method and uses non-organic material.

Point3 Free control of sheet resistance values

Control of sheet resistance values within the range of 1kΩ/sq - multiple TΩ/sq. Even with high resistance, the films still retain the transparency (transmittance rate) expected of transparent conductive films.

Manufacturing examples

Sheet resistance values Transmittance*
Example 1 800 kΩ/sq 98.1%
Example 2 33 MΩ/sq 98.2%
Example 3 3 GΩ/sq 98.5%

*Transmittance for 550 nm wavelengths measured with glass reference

Applications


In-cell liquid crystal touch panel displays

Using inorganic high-resistance transparent conductive films to manufacture in-cell liquid crystal touch panel displays provides the twin benefits of a slimmer device and greater touch sensitivity.


Small cameras, etc. Transparent heaters covering microscopic areas

These heaters can be applied to products, such as small camera lenses, that require heating without loss of transparency. Transparent heaters can even prevent frost and dew condensation over microscopic areas, maintaining clear visibility.

*For example, when heating a 100 mm corner region to above 30℃ with a working voltage of 48V, the resistance of transparent conductors can be held to several hundred Ω/sq, but when heating a microscopic corner region of 5 mm to above 30℃ with a working voltage of 48V, a transparent conductor resistance of several hundred kΩ/sq becomes necessary.
