On March 27 the MicroLED Industry Association will host a private webinar on perovskite materials for the microLED industry. Perovskite materials hold great promise for the solar industry and in recent years we are seeing promising signs for the adoption of perovskites the display industry.

The upcoming Seminar will feature four world-leading speakers, and will also be open to a Q&A session. We will learn more about the state-of-the-art perovskite research and development, with a focus of course on applications in the microLED industry - for both perovskite QDs and PeLEDs.

According to reports, Kateeva started to ship quantum dots inkjet printing equipment to Samsung Display, for the production of QD-OLED panels. It appears as if Samsung is interested in producing 8K QD-OLEDs, and its current inkjet printing supplier, Semes, is not ready with printers that support 8K QD deposition.

Kateeva announced that it has designed a new system, called the YIELDjet Jarvis, that supports 8.5-Gen substrates and can indeed enable 8K TV deposition. Kateeva says that the Jarvis system has the ability to print using solvent-based RGB inks or nanoparticle inks with its proprietary ink recirculation system to ensure uniform particle distribution.

Toray Research Center (TRC) is now hosting online webinars focused on display technologies. TRC, who supplies technical analysis and support for R&D and manufacturing, invites you to attend the online lectures at no cost, to learn more about OLED, microLED and QD technologies and analysis of OLED devices.

The webinars include recorded presentations, which will be available online up until to November 22. You can register for the webinars here.

The webinar will include three different presentations:

• OLED dopant ratio for efficient emission
• Laser-based processes for microLED production, analysis method to evaluate chips after transfer
• Degradation analysis of QD-LED devices

In the next two weeks, Toray Research Center (TRC) is hosting online webinars focused on display technologies. TRC, who supplies technical analysis and support for R&D and manufacturing, invites you to attend the online lectures at no cost, to learn more about OLED, microLED and QD technologies and analysis of OLED devices.

Esteemed US-based A/V retailer Value Electronics conducted its latest annual TV shootout, with very interesting results. It is not a big surprise, but OLED TV won the first places in both the 4K and 8K shootout.

In the 4K category, VE tested five TVs, out of which 3 were OLED TVs: The LG G2 OLED TV, Samsung S95B QD-OLED, Samsung QN95B (QD miniLED), Sony A95K QD-OLED and Sony's X95K mini-LED. The winner of this year's shootout was Sony's A95K QD-OLED.

TechBlick announced a new virtual event, the industry's first event focused on miniLEDs, microLEDs and Quantum Dots displays.

TechRadar posted an interesting article that reviews Samsung's latest miniLED TV (QN85B Neo QLED, to be exact) and compares it with LG's OLED TVs.

The miniLED TV is excellent with high brightness, excellent color performance and a very good design. But at the end of the day, the image quality is not as good as the quality you get from an OLED TV, especially as the display suffers from blooming/haloing and non-consistent black scene performance.

This article was extracted from the Perovskite for Displays market report.

Given perovskites materials' unique optical properties, these materials are being intensively researched for both photovoltaic and display applications (as well as several others). In this article we will take a look into the possible application areas in the display industry that can benefit from perovskite materials.

Perovskite QDs

Perovskite-based QDs (PerQDs) are considered a viable Cd-free alternative for display applications, with high PL quantum yields, wide wavelength tunability and ultra-narrow band emission. The main advantages of PerQDs are:

• Low cost
• High performance
• RoHS compliance (despite the lead content)

According to reports in Korean media, Samsung is developing a new process which will allow it to reduce the thickness of its QD-OLED panels.

The current QD-OLED design uses two glass substrates, one for the TFT backplen (and the OLED frontplane materials), and one for the QD conversion layer. The new plan is to remove the QD glass substrate, and inkjet print the QDs directly on the OLED TFE encapsulation layer.
