Embodiments of an enclosed coating system according to the present teachings can be useful for patterned area coating of substrates in the manufacture of a variety of apparatuses and devices in a wide range of technology areas, for example, but not limited by, OLED displays, OLED lighting, organic photovoltaics, Perovskite solar cells, and organic semiconductor circuits. Enclosed and environmentally controlled coating systems of the present teachings can provide several advantages, such as: 1) Elimination of a range of vacuum processing operations such coating-based fabrication can be performed at atmospheric pressure. 2) Controlled patterned coating eliminates material waste, as well as eliminating additional processing typically required to achieve patterning of an organic layer. 3) Various formulations used for patterned coating with various embodiments of an enclosed coating apparatus of the present teachings can have a wide range of physical properties, such as viscosity and surface tension. |
