Amorphyx Q&A about champion performance in IGZO TFT for OLED Smartphone applications

This is a sponsored post by Amorphyx, where display industry consultant Ian Hendy has interviewed Amorphyx's CEO John Brewer

Q: Can you start by telling us a little about what Amorphyx does, John?

Amorphyx has several fundamentally new technology platforms that provide for TFT performance improvements in three areas: (1) Switching speeds, with options to move to the Tera-Hz range ultimately, (2) Power, where the IGZO AMeTFT can achieve even lower power performance than today’s LTPO OLED Pro Motion displays and better refresh range, and (3) Small transistor size.

Our technology platforms are lower cost than the alternatives, and move from amorphous and crystalline semiconductor approaches, to devices based on different effects that do not have a semiconductor at all, yet can still drive a display, drive current, deliver grey scale and switch very fast. Or they can operate a flex IC at higher clock speeds than known today.

For now, our main commercial focus is on IGZO AMeTFT which is fundamentally a potential replacement transistor for LTPS or LTPO used in modern OLED phones and has the capability to replace more highly compensated LTPO circuits in modern Smartphone displays due to enhanced stability.

RiTDisplay and SmartKem join forces to develop OTFT-AMOLED displays

UK-based OTFT display backplane developer SmartKem announced that it has signed a joint development agreement with Taiwan-based PMOLED-maker RiTdisplay, for the production of OTFT-based AMOLED display prototypes.

SmartKem's technology could enable RiTDisplay to produce AMOLED displays at a lower cost, and, more significantly, to use its own PMOLED production line without the large investment needed for an LTPS AMOLED Line. The current agreement includes a prototype display development, it will have to be seen whether it will be expanded in the future for actual production.

Samsung announces a new variable refresh rate technology for its latest AMOLED displays

Samsung Display announced a new OLED technology, called Adaptive Frequency that enables variable refresh rate in AMOLED displays - ranging from 10Hz to 120Hz. Running OLEDs at low refresh rates when possible can reduce the power consumption of the display (over all applications) by up to 22%.

Samsung Variable Refresh Rate OLED Technology testing

This new display technology was applied for the first time in the Galaxy Note20 Ultra 5G smartphone, announced earlier this month, with its 6.9-inch 1440x3088 Dynamic AMOLED.

OLET developer Mattrix Technologies announces an additional $1.5 million investment by JSR

Organic-TFT backplane/emitter developer Mattrix Technologies (previously nVerPix) announced that it has received a $1.5 million investment from JSR Corporation. This second investment by JSR is the first tranche in the company's new round (which will total, hopefully, $3 million)

JSR is a strategic investor, and has also launched a joint-development project for the development of solution-based conductive inks that will be sued in Mattrix's next-generation backplane transistors.

Samsung launches several new AMOLED devices, including the Note 20 and the Galaxy Z Fold 2

Samsung announced several new OLED devices yesterday. We'll start with the new Galaxy Note 20 which sports a 6.7-inch 1080x2400 HDR10+ Super AMOLED Plus display (which could mean this is an RGB display, not a Pentile one). The Galaxy Note 20 Ultra has a larger 6.9-inch 1440x3088 Dynamic AMOLED. The display supports a refresh rate of 120Hz at Full-HD resolution and 60Hz at QHD. According to the Elec in Korea, the Note 20 Ultra display has an LTPO backplane (which Samsung calls HOP).

Next up is the company's 2nd generation Galaxy Z Fold 2 that is an update to the original fold with a larger internal foldable display at 7.6" 1768x2208 HDR10+ 120Hz Dynamic AMOLED and also a larger 6.23" 816x2260 Super AMOLED cover display. The Fold 2 also improves the hinge design and sports an ultra-thin-glass cover (like the Galaxy Z Flip).

Coherent's display orders were up significantly for LineBeam systems and service. These systems orders are all destined to China, and the increase in service orders "reflects higher demand for OLED-equipped smartphones in Q4 2019". Orders for OLED cutting using short pulse and CO2 lasers were also up.
