thin-film encapsulation (OLED) (TFE)
Thin Film Encapsulation (TFE) is a technology that protects electronic components such as OLEDs from external influences, dust, water, air and moisture.
In general, the encapsulation of the components can be done by glass encapsulation. However, such encapsulation is extremely inflexible. The situation is different with thin-film encapsulation. As can be seen from the name, thin-film encapsulation is a multilayer encapsulation of the components consisting of a multilayer film. Alternating organic and inorganic layers. The inorganic layers typically consist of metal oxides and serve as a moisture barrier. Since these layers could become brittle in the long term and allow moisture to pass through, they are protected by an organic film, which also increases flexibility.
