OLED Encapsulation

An organic light-emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current OLEDs are used to create digital displays in devices such as television screens, computer monitors, and portable systems such as smartphones and handheld game consoles. Rigid OLED displays are encased in a glass sheet because glass is a durable barrier and is easy to handle. For the next generation of flexible OLED displays, the glass sheet is replaced with a transparent Thin Film Encapsulation layer.

Deposition Methods for OLED Encapsulation

Denton’s unique, patented Plasma Ion Beam CVD technology can deposit both inorganic and organic layers in a single system whereas two separate systems are used in limited production today. The Phoenix PIB-CVD linear ion source can control both ion energy and ion current density, the key to being able to deposit organic and in-organic layers in a single system. This source can be scaled to 2 meters in length, making it suitable for depositing on large area sheets of plastic or very thin glass. The source is also easy to maintain, making the Phoenix PIB-CVD a perfect solution for high volume production needed to commercialize flexible OLED displays.
