Inkjet Printing of OLEDs Comes of Age

That’s two more reports out of the way, with the AWE Expo report in MDM and the Infocomm report in LDM. Added to the normal issues this week, my keyboard has taken something of a hammering! There is one special report for LDM still to be done, from the CineEurope show. From over 100 source articles to write in our CMS system, I’m down to under 10.

I’ve been training for the last couple of weeks for a bike ride in the French Alps so the view out of my window is shown below. Because of the scale of the reports that needed doing, all I have done for a couple of weeks is type, occasionally cycle up some Cols, cook and sleep. My landlord calls me ‘The Hermit’. He is also not used to visitors that arrive at his holiday cottage with their own 32″ 4K monitor! This year, he still has only ADSL with 2 Mbps, but next year fibre gets to this part of the Alps, which will boost capacity and would make production a little quicker.

Longer term readers might recognise the view as this is the fourth time I have stayed here!

We will have some more special reports as Chris was running the Samsung-sponsored event in LA this week and Matt headed over to create a report based on what was covered. Then things will slow down, with only Siggraph as a major event in August before we ramp up again with the IFA/IBC overload in September.

Our front pages this week cover the JOLED news that it is in a position to go ahead with a 5.5G printed OLED fab. As we have mentioned many times, inkjet printing has long been one of the potential manufacturing technologies for OLED. Inkjet printing is widely used in the display industry, especially for colour filter manufacture and for thin film encapsulation of OLEDs. Kateeva is one of the big suppliers and its eight years since we reported that the company could make OLEDs using its printers. One of the early advisers was from Litrex, which was acquired by CDT back in December 2001 to speed up the adoption of inkjet printing. CDT had been working with Epson since early 1998 (Display Monitor Vol 5 #9), so we are now past twenty years in trying to develop the concept. At that time, they had been working together for more than a year, so IJP of OLEDs has now ‘come of age’.

That’s a reminder of how long things can take to develop in this incredibly competitive and demanding display industry.
