For OLED

FLAT ITO Films

Transparent conductive films with smooth surfaces

Overview

For organic thin film devices, conductive films with a smooth surface are best.
We provide films that can be used even without polishing.

Features & Strengths

Point1 Smooth surfaces

Flat films realized by controlling grain size

Point2 No polishing necessary

Reduces polishing process required for smooth film, improving cost and yield

Applications


Illumination

Create comfortable spaces with natural colors and gentle light

Specifications

Superior Patterning and Resistance Value

Flat ITO film has a uniform domain structure, creating smooth patterned edges. In addition, we have achieved low resistance equal to standard ITO films and low membrane stress, meaning low stress on the substrate as well.
In addition, we have achieved flatness equal to polished surfaces and no polishing is necessary after the film is applied, meaning one less process to deal with. This also means freedom from the concern of residue or damage after polishing.
