Nanosys expects to show working emissive QD-LED displays by the end of 2019

HDTVTest posted an interesting interview with Cadmium-Free QD developer Nanosys CEO and president Jason Hartlove. In this long interview Jason discusses the company's technology and recent achievements.

Jason reveals that the company is working on emissive Quantum Dots displays - and he expects to have a full-color monitor-size QLED display prototype ready by the end of 2019. Jason says that they hope to show these display prototypes in private demos at CES 2020.

Hisense's new ULED XD technology uses dual LCD panels to achieve high contrast

China-based Hisense announced a new technology that the company says will enable its LCDs to compete with OLEDs in high contrast. The so-called ULED XD panels use two LCDs panels, on on top of the other. The inner LCD is a monochrome (geyscale) FHD LCD that is used to block the light on low brightness images, and on top of it is the usual 4K full-color LCD.

This is basically a way to achieve a high number of 'local dimming' zones for an LCD display (over 2 million such zones, in fact). The TV itself is very bright (over 2,900 nits) and reportedly offers a great image quality and an almost perfect contrast. HiSense it will release its first ULED XD TVs later this year in China. Apparently SkyWorth is also demonstrating a similar technology at CES.

Perovskites show great promise for QDLED displays

Truly emissive Quantum Dots LEDs is a potential next-generation display technology, that's been under development for many years. In the past years, we've seen great interest in perovskite materials and perovskite-based Quantum Dots, while still at an early stage of research, are showing great promise. Our sister site Perovskite-Info published an interesting article by Ossila that discusses the merits and current status of pQDs.

We have recently published a guide to perovskite materials, technology and industry which we consider a valuable source of early stage information for anyone wishing to keep up with the latest trends in our industry.

Samsung unveils new Micro-LED TV prototypes at CES 2019

CES is only starting tomorrow, but companies are already unveiling some of the new products and prototypes. Samsung is showing two new Micro-LED TV prototypes, a 75" consumer TV and a large 219" professional signage display.

Samsung did not reveal any details or commercialization plans for its new 75" MicroLED-TV. The company is reportedly close to release a hybrid QD-OLED TV in 2019, but it would seem that Samsung hopes that Micro-LED panels will be the company's next-gen flagship TV technology.

Business Korea: LGD delays the construction of its P10 fab

Towards the end of 2015 LG Display announced that it plans to build a new OLED fab (P10) in Paju in a $8.7 billion investment. The P10 was supposed to produce both LCD and OLED displays (mostly OLED TV panels, but also mid-sized flexible OLEDs), and production was planned to begin towards the end of 2018.

In 2017, we heard reports that LGD decided to cancel the LCD production at the P10 fab and focus exclusively on OLED displays. A new report from Business Korea confirms this report - and says that LG also decided to postpone the production at the P10 as the shift to OLED technologies is challenging - especially as LGD intends to produce OLEDs on 10.5-Gen substrates for the first time at the P10 fab.

The Washington Post mistakenly blame OLEDs for low battery life in 2018 smartphones

The Washington Post's Geoffrey A. Fowler posted an interesting article in which he details how new smartphones are under-performing older ones in terms of battery life. Geoffrey puts 12 smartphones to the same test, and checks which ones dies first.

It is interesting that the new 2018 smartphones under performs similar smartphones released in 2017. Geoffrey's conclusion is that new display technology - high resolution OLEDs, are the culprit. The main reasoning behind that is that the iPhone XR (with its LCD display) performs better than the iPhone XS, even though the XR has a smaller display.

Are OLED smartphones better for your eyes? NTHU researchers say yes

Excessive exposure to blue light has been linked to many health issues - including cancer, diabetes, heart disease, obesity and insomnia. Children, especially, have delicate retinas that are highly susceptible to the dangers of blue light.

Researchers from Taiwan's National Tsing-Hua University, led by Prof. J.H. Jou, have been advocates of candle-light OLED lighting for a long time, as part of their fight against the hazards of LEDs and white light. In 2015, the researchers published a call out to consumers to be aware of the hazards of LEDs and to governments to enact new rules to enforce light-based products to show the light spectrum.

DSCC: flexible OLEDS carry a 5X premium over LTPS LCDs

Display Supply Chain Consultants (DSCC) estimates that a 6" flexible OLED Module (with a touch layer) costs around $78 (and will drop slightly to $76 by the end of the year). Meanwhile the price of a similar rigid OLED is around $26 and an LTPS LCD is around $16.

LCD producers have lowered the prices dramatically in the last two years (from $29 in early 2017 to $16 today), and rigid OLED producers have been forced the lower their prices as well (from $42 in early 2017 to $26 today).
