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.

Polymeric planarization layers play a pivotal role in OLED displays’ thin‐film encapsulation. With its low material consumption, deposition geometry flexibility, high throughput, and reliability, inkjet printing is the preferred deposition technology for such films.

In the past, there have been a lot of different image file formats, providing a lot of different capabilities. However, the one thing they pretty much all shared was a very limited mechanism for encoding color. Storing a color image today forces developers to take either a "lowest-common-denominator" approach by using a single standard colorspace in all applications, or by using the capabilities of ICC color management at the loss of wide interoperability.The JPEG 2000 file format changes all this with a new architecture for encoding the colorspace of an image. While the solution is not perfect, it does greatly increase the number of colorspaces that can be encoded while maintaining a very high level of interoperability between applications. This paper describes the color encoding architecture in the JPEG 2000 file format and shows how this new architecture meets the needs of tomorrows imaging applications.
