RiTDisplay is a Taiwanese company, manufacturing PMOLED panels. RiT has been spun-off from Ritek, that still holds a majority stake. RiTDisplay is one of the world's largest PMOLED makers.

RiTDisplay went public in 2016, following a strong rise in PMOLED demand. The company is trading in the Taipei Stock Exchange (8104:TT)

In June 2011 it was reported that RiTDisplay is collaborating with IGNIS on AMOLED panel production on a-Si backplanes. That project never took off, though. The company is now developing flexible PMOLEDs.

In 2019 RiT signed a strategic partnership with PlayNitride and aims to start developing and producing MicroLED displays.

Taiwan forms an OLED lighting commercialization alliance

The OLED Lighting Commercialization Alliance (OLCA) was formed a few days ago in Taiwan, with an aim to make Taiwan an important OLED lighting player. The alliance will promote OLED technologies and will include members from materials suppliers to product makers.

The OLCA seems to be led by Taiwan's ITRI. Other members include Merck, RiT Display, WiseChip, Corning, Tongtai Machine & Tool and the TLFEA (Taiwan Lighting Fixture Export Association). ITRI says that more than 60 companies have shown interest in collaborating with OLCA members.

Updates from Taiwan's AMOLED makers

Taiwan has a large display industry, but in recent years it seems that it is lagging behind Korea, Japan and China in AMOLED technologies. We asked a local industry expert to check out the three main Taiwanese AMOLED companies (AUO, Innolux and RiTDisplay), and now we post on his updates.


As we reported already, AUO started producing AMOLEDs in their 4.5-Gen fab in Singapore after years of delays. According to our source, AUO is actually only producing samples. Those 5" 720p (295 ppi) panel samples have been been submitted to a company based in China. Earlier reports suggested AUO is going to supply HTC and Sony but it appears these two companies will keep using LCDs for now.

Reports from Korea claim LG Display is on the verge of a flexible OLED supply deal to Apple

Back in December 2012, rumors started to circulate about an upcoming Apple smartwatch called the iWatch. First we heard reports that it will use a small PMOLED, and later rumors suggseted Apple decided to use a plastic flexible OLED. Today the Korea Herald claims that LG Display is very close to striking a deal with Apple to supply flexible OLEDs for the iWatch.

Korea Herald says that it isn't likely for Apple to rely on a single vendor and they suggest that RiTDisplay is a strong candidate as well. But this does not seem likely as the Taiwanese company does not have the technology or capacity to produce flexible AMOLEDs similar to LGD ones. Perhaps if Apple opts for a simpler PMOLED device than RiTDisplay is a possible supplier. They also list Japan Display as a candidate, but this is even less likely.

Ignis to start producing 20" AMOLED displays in low volume beginning August 2013

Ignis Innovation announced that samples of its 20" 1296x768 (XGA) AMOLED display will be available in August 2013. Ignis will offer these samples to display makers for evaluation of Ignis' MaxLife compensation technology in their own displays (more on this below). They will sell the display for low volume, demanding applications such as medical imaging and scientific imaging.

The 20" AMOLED panels use a-Si backplane and are made by RiTdisplay. The panels are only 1.3mm thick (the complete display module is 3 mm thick). The refresh rate is 240Hz.

Apple reportedly testing iWatch prototypes with RiTDisplay 1.5" PMOLED displays

Back in December 2012 we posted a new Apple OLED rumor - about the iWatch: a bluetooth smart watch that has a 1.5" touch PMOLED, apparently made by RitDisplay. In February 2013 the New York Times and the Wall Street Journal both posted about this rumor.

Today these rumors resurfaced. This time Taiwan's Economic Times reported that Apple had made some prototypes with a 1.8" PMOLED, but decided they were too large. Now they are testing 1.5" PMOLEDs, and have ordered a thousand units from Foxconn - for internal experimentation.

Is Apple's iWatch device real?

A couple of months ago we posted about a rumor claiming that Apple is working on a PMOLED Bluetooth smartwatch. Now the New York Times and the Wall Street Journal are both posting a similar story, which actually gives this rumor some credibility. This time they say that Apple is working with their long-time manufacturing partner Hon Hai Precision Industry.

We're not sure what is meant exactly by "curved glass". We have seen devices with curved rigid glass before (for example the Nexus S). The New York Times speculates that the new iWatch will use Corning's flexible Willow glass (shown in the video below) - and so probably the whole display will be curved, maybe something similar to the prototypes Samsung unveiled at CES.

Rumor: Apple is working on a PMOLED bluetooth smart watch

Apple OLED rumors never die. This time these are rather different rumors. According to a Chinese tech blog, Apple and Intel are jointly developing a bluetooth smart watch. This new iWatch (or whatever they'll call it) will have a 1.5" touch PMOLED, apparently made by RitDisplay.

I'm usually quite skeptic on Apple AMOLED rumors, because there's still not enough AMOLED capacity to be used in iPhone or iPod devices. But ramping up PMOLED capacity shouldn't' be a problem for RiTDisplay (which used to have larger capacity than today, but they shut down some lines due to financial problems). Anyway, if this is true, it's great news for my friends over at RiTDisplay.

Ignis Innovation at SID 2012

As I already said before, Ignis Innovation's SID booth was one of the conference highlights for me. Their technology is very impressive and hopefully will enable cheaper non-LTPS AMOLED production.

In their booth, Ignis were showing 3.5" and 20" AMOLED panels that use the company's a-Si backplane compensation technology. The panels were made by RiTdisplay. Ignis and RiTdisplay have been showing these displays back in 2011. Originally they were supposed to be released towards the end of 2011, but this never happened. During SID Ignis announced that now the plan is to release these by the end of 2012. According to Ignis the 3.5" AMOLED will be cheaper than the LTPS-based competition (i.e. Samsung made panels). You can read more about these panels and RiTdisplay's plans at my RiTdisplay-at-SID-2012 post.

RiTdisplay at SID 2012

RiTdisplay is a PMOLED producer based in Taiwan that has several production lines making PMOLED panels. A few years ago it was considered the world's largest PMOLED maker, although I now hear that due to financial problems the company shut down some of their PMOLED lines (this isn't confirmed though).

At SID 2012, RiTdisplay showed several PMOLED panels, and some 3.5" AMOLED panels. RiTdisplay is Ignis' production partner for its a-Si compensation technology, which basically enables a-Si to be used as a backplane for AMOLED panels (instead of LTPS or Oxide-TFT). This should enable cheaper AMOLEDs. You can read more about this technology at my Ignis-at-SID post.

First impressions from SID 2012

Update: Here's the complete list of OLED related posts and notes from SID 2012

So, SID 2012 is now over. Personally it was a very good show, even though I hear from many exhibitors that it was slow compared to past years. There were a lot of companies showing OLED displays, lighting panels and related products, and it seems that OLEDs are starting to become mainstream. I do plan to post in-depth posts with interesting details of my talks with various OLED companies, but in the meantime, here's my own "best of SID" list.
