UK-based Excyton is happy to announce that it will showcase its novel TurboLED OLED architecture and technology at the 2023 Displayweek event (May 23-25, Los Angeles, California). Excyton has been accepted to participate at the 2023 I-Zone event.

TurboLED is a game-changing technology that offers a dramatic boost to the performance of displays. In a TurboLED OLED display, each pixel comprises deeper and lighter color red, green and blue emitters to maximize performance - in fact Excyton has shown that the TurboLED architecture leads to a 50% reduction in power consumption, a 3X improvement in emitter lifetime and an increased color gamut. TurboLED displays are especially suited for demanding applications, such as IT displays, automotive displays, gaming monitors, AR/VR headsets, smartphones and wearables.

The Fraunhofer FEP research institute announced that it has developed the world's highest-density OLED microdisplays, reaching a PPI of 10,000 with a pixel size of only 2.5 um. The Fraunhofer will demonstrate a 0.18" 1440x1080 (monochrome) OLED microdisplay next week at Display Week 2023.

The new microdisplays were produced on 300 mm wafers, using a 28 nm backplane process. The Fraunhofer explains that most OLED microdisplays to date are produced on 200 mm wafers, using CMOS processes ranging from 90-250 nm. The institutes new technologies enables the the performance increase in OLED display processing. 

Apple's interest in OLED displays for future iPad tablet device is not secret, and many analysts estimate that the first such device will be released in 2024.

One of Apple's requirement is for superior performance for its tablets compared to smartphone AMOLED displays - and so developers are relying on a tandem OLED structure. According to a new report from Korea, LG Display is developing another unique technology for Apple's iPads.

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.

Kopin Corporation announced today it has received new orders for its OLED microdisplays and silicon backplane products. These new orders come from new customers.

Kopin says it has started to ship 720p dual-stack 0.49" OLED microdisplays to a new customers, for thermal imaging viewfinders. The company also received a new order for its 2K OLED backplane wafer.

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.

Organic-TFT backplane/emitter developer Mattrix Technologies has demonstrated a new AMOLED display prototype that is based on an amorphous-silicon (a:Si) backplane.

Mattrix believes that its proprietary vertical, organic light-emitting transistor (VOLET) pixel technology can dramatically reduce OLED production costs and improve display quality.

UK-based SmartKem develops a new class of flexible high-mobility OTFT display backplane technologies. The company provides customized solutions involving molecular synthesis, electronic prototyping and on-site technology transfer support.

As Smartkem is developing new backplane materials for OLEDs, ePaper and mini-LED devices, we discuss its technology and business with the company's CEO and chairman, Ian Jenks.

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%.

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.

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.
