The present teachings relate to various embodiments of an ink composition, which once printed and cured forms an organic thin film on a substrate such as, but not limited by, an OLED device substrate. Various embodiments of the ink compositions comprise polyethylene glycol di(meth)acrylate monomers, mono(meth)acrylate monomers and multifunctional crosslinking agents.

Di- and mono(meth)acrylate based organic thin film ink compositions

Ink compositions formulated for inkjet printing the hole injecting layer (HIL) or hole transporting layer (HTL) of an organic light emitting diode (OLED) are provided. The ink compositions comprise fluorosurfactants that prevent uncontrolled spreading of the printed ink compositions. Also provided are methods of inkjet printing the HILs or HTLs using the ink compositions.

Fluorosurfactant-containing ink compositions for inkjet printing

The present teachings relate to various embodiments of an ink composition, which once printed and cured forms an organic thin film on a substrate such as, but not limited by, an OLED device substrate. Various embodiments of the ink can be printed using an industrial inkjet printing system that can be housed in a gas enclosure, which gas enclosure defines an interior that has a controlled environment maintained as an inert and substantially low-particle process environment. Patterned printing of an organic thin film on a substrate, for example, but not limited by, an OLED device substrate, in such a controlled environment can ensure a high-volume, high yield process for a variety of OLED devices.

Organic thin film ink compositions and methods

Ink compositions formulated for inkjet printing the hole injecting layer (HIL) or hole transporting layer (HTL) of an organic light emitting diode (OLED) are provided. The ink compositions contain fluorosurfactants that prevent uncontrolled spreading of the printed ink compositions. Also provided are methods of inkjet printing the HILs or HTLs using the ink compositions.

Ink compositions comprising polythiophenes and aprotic organic solvents that are formulated for inkjet printing the hole injecting layer (HIL) of an organic light emitting diode (OLED) are provided. Also provided are methods of inkjet printing the HILs using the ink compositions.

Polythiophene-containing ink compositions for inkjet printing

Ink compositions comprising polythiophenes and methicone that are formulated for inkjet printing the hole injecting layer (HIL) of an organic light emitting diode (OLED) are provided. Also provided are methods of inkjet printing the HILs using the ink compositions.
