Abstract
OLEDs (organic light‐emitting diode) are one of the prevalent display technologies and their penetration in the consumer electronic market is fast growing. As a reliable and cost‐effective deposition technique for polymeric planarization layers, inkjet printing has been successfully applied to the mass production of flexible OLED displays. In this paper, we present the concept that for today's common ranges of process layer thickness, the quality and consistency of the deposited polymeric film can be agnostic to the selection of drop volumes. However, printer flexibility in terms of drop size and printhead support is critical to meeting the full range of current and future processes adopting the proven inkjet printing process. Applications utilizing the state‐of‐the‐art Kateeva inkjet printing systems are presented to demonstrate our study and for the reader to be able to assess if inkjet technology could be advantageous for a particular OLED application.
