Quantum Dots - Page 6

Samsung is developing its QD-OLED TV technology and the company was supposed to hold an investment review committee on April 2019 to decide whether to go ahead with plans to start production soon (mass production by the end of 2020).

However in May we later reported that Samsung decided to delay the production - trial production will begin towards the end of 2020, with real mass production on a new 10-Gen line only at around 2023. A new report from Korea sheds some more light on Samsung's situation.

TCL unveiled that the company is developing a new hybrid display technology that uses a blue OLED emitter coupled with red and green QD emitters. All three emitter materials will be combined and printed using ink-jet printing technology. TCL calls this technology H-QLED and this could prove to be the technology of choice for TCL's future high-end emissive TV displays.

It seems as TCL believes that commercial-level red and green QD emitters will be achievable in the future, but blue QD emission will be more difficult to develop, and hence it will rely on OLED emitters. TCL did not disclose more details - but this R&D effort is being performed at the company's Juhua Printing platform.

According to reports, Samsung Display will hold an investment review committee on April 2019 to decide whether to go ahead with plans to start producing QD-OLED TV panels. If the plan is approved, Samsung will start installing production equipment towards the end of 2019, with mass production starting by the end of 2020 or early 2021.

According to earlier reports, Samsung aimed to start pilot production of QD-OLED TV panels in 2019. It's not clear whether the new reports suggest a delay or whether they only refer to the mass production step, with pilot production proceeding as planned.

DSCC says that production costs for a 55" QD-OLED TV panel at Samsung Display's 8.5-Gen fab will reach almost $800 in 2019. While this will fall to around $450 in 2022, Samsung will still lose money on every panel sold if DSCC has its price and cost estimates right.

It is important to note that most of the cost is depreciation costs - which means that in terms of cash on each panel, SDC's margins will actually be around 40%. Part of the reason for he high cost of required equipment is the need to use 12 TFT masks.. SDC is apparently looking to reduce the mask number which will lower production costs.

Samsung Electronics reported its financial results for Q4 2018, with revenues of KRW 59.27 trillion ($53 billion USD), down 10% from Q4 2017. Samsung's operating profit of KRW 10.8 trillion ($9.6 billion) was down 29% from 2017.

Samsung Display reported a decline in rigid smartphone OLED display sales - due to rising competition from LCD panels. Demand for flexible OLEDs was strong. In Q1 2019, OLED display sales will remain weak - but Samsung says that flexible OLED demand will pickup in the second half 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.

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.

According to ETNews, Samsung Display has made significant progress with its OLED ink-jet printing process technology, and the company now aims to apply this technology to produce medium-sized panels for OLED laptops and OLED monitors. Samsung may also use this process to produce smaller tablet displays.

It seems that Samsung is aiming to settle on three main next-generation OLED technologies - evaporation (FMM) OLEDs for small-sized display, ink-jet OLED deposition for medium-sized panels and hybrid QD-OLEDs for large-area OLED TV panels. It's other display technologies are QD-LEDs for TVs and Micro-LEDs for next-generation small and large area displays.

Samsung Display is developing hybrid QD-OLED TV technology, and according to estimates, the company aims to begin trial production in 2019. It seems that Samsung is managing to overcome the technical challenges and the company is preparing to start production of such QD-OLED TVs in 2019.

Last month Digitimes updated about Samsung's plans to start installing equipment by the end of 2018 and begin trial production in H2 2019. Digitimes now posted another article, revealing more details on Samsung's plans.

The OLED-Info team takes pleasure in recommending our new book - The Perovskite Handbook, which gives a comprehensive introduction to perovskite materials, applications and industry. We believe that any display professional would find that perovskite materials are an area of focus that should not be ignored.

Perovskites offer a myriad of exciting properties and has great potential for the display industry. The promising perovskite industry is currently at a tipping point and on the verge of mass adoption and commercialization and the first display-related perovskites are already reaching the market.
