“…Recently, Kateeva announced the development of an ink jet printer for OLED mass production [7] for Gen 8 Fab. AUO has reported [8] on development of a FHD, 65-inch inkjet printed OLED panel using solution processable OLED materials for the hole injection layer (HIL), the hole transport layer (HTL), and the emitting layer (EML) for the Red, Green and Blue emitters. This demo with uniform pixel efficiency is very encouraging.…”

Organic light emitting diode (OLED) display technology has advanced significantly in recent years and it is increasingly being adapted in consumer electronics products with premium performance, such as high resolution smart phones, Tablet PCs and TVs. Even flexible OLED displays are beginning to be commercialized in consumer electronic devices such as smart phones and smart watches. In addition to the advances in OLED emitters, successful development and adoption of OLED displays for premium performance applications relies on the advances in several enabling technologies including TFT backplanes, pixel drive electronics, pixel patterning technologies, encapsulation technologies and system level engineering. In this paper we will discuss the impact of the recent advances in LTPS and AOS TFTs, R, G, B and White OLED with color filter pixel architectures, and encapsulation, on the success of the OLEDs in consumer electronic devices. We will then discuss potential of these advances in addressing the requirements of OLED and flexible displays for the military and avionics applications.

“…Hard to find proper fine metal mask (FMM) is the biggest issue for evaporation process . Currently, the best method to achieve high‐resolution AMOLED without FMM is printing process . However, printing process is more suitable for resolution lower than 200 ppi (pixel per inch), because the inkjet droplet volume from the nozzle head is too large and adjacent pixels are easy to be bridged .…”

A 403‐ppi (pixel per inch) real RGB active‐matrix organic light‐emitting diode (AMOLED) was fabricated without using fine metal mask (FMM). Organic light‐emitting materials were printed on array panel, with a novel process that has the advantages of low cost and high pixel density. The uniformity of the organic light‐emitting diodes (OLEDs) was improved with carefully tuning printing parameters, and good panel performance was achieved. The key to such a process was the design of the hexagonal patterning of the pixels. The image quality of the panel with this hexagonal pixel arrangement was evaluated with a bmp format Pixel Layout Simulation picture.

“…The panel was produced using a fine metal mask for red/green/blue color patterning and the dam-and-fill technology for encapsulation. Meanwhile, after numerous demonstrations, we established a stable oxide thin film transistor (TFT) platform using Gen 6 (1500 mm x 1850 mm) glass to further investigate additional advanced TFT technologies or organic material coating processes other than thermal evaporation, such as the IJP process [4]. Recently, we completed the AMOLED TV with novel cathode architecture.…”
