Apparatus and method for separating carrier liquid vapor from ink

Abstract

Systems, apparatus, and methods are provided that include or use a chuck, an inkjet printhead, and an air knife to form a film layer on a substrate that has uniform feature sizes and avoids stacking of inkjet inks. In some systems, a gas moving device is used instead of a gas knife. The systems, apparatus and methods can be used to print layers on substrates to be used in organic light emitting devices.

Problems solved by technology

Recondensation can cause buildup of unwanted material in equipment

Such buildup on the transfer surface may result in transfer of the carrier liquid to the intended substrate, causing contamination or redissolution of the deposited film
