State of the AMOLED industry and future fabs

This is a premium OLED-Info article

When Samsung started producing AMOLED displays in 2007, AMOLED technology was at a very early stage, immature, and Samsung took a huge risk. A few years later, this risk was rewarded with a successful display business and a boost to the company's smartphone business that was the first to adopt AMOLED displays.

Fast forward to 2016, and today Samsung is still the king of AMOLED displays, with a market share of over 95% in small/medium AMOLED panels. If we look at OLED TV production, then LG Display is the only commercial producer at this stage. But Samsung and LG are not alone - several companies in China and Taiwan already started mass producing AMOLEDs, and others have announced plans for large AMOLED fabs. In this long article we'll list all of these AMOLED producers and developers (over a dozen) - and details their current production capacity and rumored and confirmed production plans.

CPT aims to produce IGZO OLEDs in a 6-Gen fab it is building in China

Aug 27, 2016

Taiwan-based Chunghwa Picture Tubes (CPT) is building a new 6-Gen fab in China, with an investment of about $1.85 billion. Digitimes reports that CPT plans to produce IGZO backplane OLED panels in its second phase.

The first phase production is scheduled to begin at around June 2017 (construction will be completed by the end of 2016 and equipment installation will begin in Jaunary 2017). The first phase will produce a-Si LCDs, with a monthly capacity of 30,000 substrates. Digitimes did not say when is the second phase planned, and what kind of capacity will be allocated to OLED displays.

ITRI developed a foldable AMOLED display, to transfer the technology to CPT

Jun 03, 2016

Researchers from Taiwan's ITRI developed a foldable AMOLED display - which fold both inwardly and outwardly.

ITRI will transfer this new technology to Chunghwa Picture Tubes (CPT) in Q4 2016. CPT will start trial production at its pilot 4.5-Gen AMOLED fab (currently used to produce glass-based rigid AMOLEDs in small volume). In August 2015, CPT signed a technology-transfer agreement with ITRI for its flexible OLEDs.

FlexEnable and CPT's OTFT flexible AMOLED prototype shown in video

Dec 16, 2015

A few months ago, FlexEnable and Chunghwa Picture Tube (CPT) demonstrated a full-color flexible AMOLED display that uses FlexEnable's OTFT backplane. FlexEnable today published a video showing the display in action:

This glass-free display is still a prototype (as you can see there are many defects) - but it's a great demonstration of a truly flexible display. It operates at 60Hz and is only 125 microns thick.

CPT expects to mass produce flexible AMOLEDs by 2017

Aug 28, 2015

Earlier this month we reported that Taiwan's Chunghwa Picture Tubes (CPT) signed an agreement with ITRI for a technology transfer for flexible AMOLED and touch panel integration. Today we hear that CPT expects to start mass producing such flexible touch AMOLEDs by 2017.

CPT has an existing pilot 4.5-Gen AMOLED fab (used to produce AMOLEDs in small volume) - and reportedly they will either convert this line to flexible AMOLED or somehow integrate it with ITRI's 2.5-Gen flexible AMOLED line. CPT will also aim to use IGZO backplanes for AMOLED production.

CPT to achieve flexible AMOLED mass production with aid from ITRI

Aug 06, 2015

Taiwan's Chunghwa Picture Tubes (CPT) signed an agreement with ITRI for a technology transfer for flexible AMOLED and touch panel integration (specifically ITRI's FlexUP flexible substrate technology - which is owned by FlexUp, encapsulation technology and flexible touch sensor technology).

CPT aims to use these technologies to achieve flexible OLED mass production "as soon as possible". Earlier today we posted that ITRI is set to demonstrate a 7" Full-HD foldable AMOLED prototype soon. ITRI and CPT has been cooperating on flexible OLEDs since 2012.

FlexEnable and CPT demonstrate a full-color OTFT flexible AMOLED display

Jun 02, 2015

FlexEnable and Chunghwa Picture Tube (CPT) demonstrate an OTFT full-color flexible AMOLED display manufactured by using FlexEnable's low-temperature process and CPT's RGB OLED technology.

The glass-free prototype display (which you can see above) is a full-color AMOLED that operates at 60Hz and is only 125 microns thick. This is a great achievement, but it's not clear whether CPT aims to commercialize such displays any time soon.

CPT shows flexible and transparent AMOLED prototypes

Sep 07, 2014

Chunghwa Picture Tubes (CPT) had some pretty interesting prototype OLED displays shown at the Touch Taiwan 2014 trade show last month. We do not have any information regarding how close are these prototypes to commercialization.

So first up is a flexible AMOLED display. This panel is 4.8" in size and 720x240 resolution (158 PPI). The company did not reveal any more technical details. The company also showed some simpler flexible PMOLED panels, demonstrating their sealing capabilities by immersing them under water (see image below).

CPT starts small-scale AMOLED production, may collaborate with AIV-BEX on OLED development

Oct 18, 2013

In 2012 we reported that CPT (Chunghwa Picture Tubes), a Taiwanese LCD and CRT producer, started developing AMOLED panels and established a small-sized pilot line. Today our sources indicate that the company actually started small scale AMOLED production. I don't have a lot of information on CPT's line at this stage.

AIV-BEX also announced that a delegation from the company visited CPT's AMOLED line earlier in October. It seems that the two companies are in talks about a possible technical collaboration. AIV-BEX plans to construct a 4.5-Gen line that uses Oxide-TFT backplanes (CPT is also developing this technology, although the current production line is not using iGZO) and ink-jet printing for the organic material deposition AIV-BEX's line will have a monthly capacity of 30,000 sheets and the plan is to begin production in 2014.

CPT shows an AMOLED based smart glass HMD

Sep 01, 2013

Taiwanese CPT is showing a new prototype smart glass HMD that uses an AMOLED microdisplay. This Google Glass like product is "ready to ship":

CPT is using a 0.5" 800x600 (SVGA) microdisplay with a display area of 10.13x7.61 mm. It simulates a 15" display from 2.5 meters. As far as I know OLighTEK (a Chinese-based OLED microdisplay maker) is the only company that ships 0.5" SVGA OLED microdisplays so it is likely that they are the display supplier. CPT is also developing AMOLED displays, but as far as I know they do not produce OLED microdisplays.
