Organic thin film ink compositions and methods

This is a special ink designed for printing very thin, organic layers, especially for making parts of OLED screens. It's made mostly of a specific type of plastic-like liquid, polyethylene glycol dimethacrylate or diacrylate, mixed with a smaller amount of pentaerythritol tetraacrylate. When printed with an inkjet and cured, it forms the desired film.

Why it matters: OLED display technology has matured and become ubiquitous since 2015, increasing demand for high-volume, cost-effective manufacturing methods like inkjet printing.
