The Realme 10 smartphone offers a 6.4-inch 90Hz 1080x2400 Super AMOLED display, a MediaTek Helio G99 chipset, 4/6/8 GB of RAM, 64/128/256 GB of storage and a microSDXC card slot.

The Realme 10 will ship by November 11, starting at $230.

According to ETNews, Apple approved LG Display's LTPO AMOLED displays for the iPhone 14 Pro, and so LGD starts to ship displays to Apple - what has been an exclusive supply by Samsung Display.

The iPhone 14 Pro has a 6.1" 120Hz 2000 nits 1179x2556 LTPO AMOLED display, while the 14 Pro Max has a larger 6.7-inch 1290x2796 panel.

According to UBI Research, Samsung Display has decided to produce QD-OLED panels at its upcoming 8.7-Gen A5 production line. The company IT display strategy will be to produce QD-OLED panels for monitor application (27-inch displays, at first) and tandem RGB panels for smaller IT displays (tablets, laptops).

Samsung is looking for design wins with Apple for both its display architectures - the larger QD-OLED panels for Apple's monitors and the smaller sized panels for its tablets.

The Polar Ignite 3 is a smartwatch that offers a 1.28" touch 416x416 AMOLED display, a 192 Mhz chipset, GPS, Bluetooth, a heart rate sensor and a sleep tracker.

The Ignite 3 will ship soon for $329.99.

Japan-based Dai Nippon Printing (DNP), the world's leading OLED FMM mask producer, is investing about 20 billion Yen (about $140 USD million) to expand the production capacity at its Kurosaki plant situated in Kitakyushu City.

DNP says that the new FMM line is expected to begin production in the first half of 2024, and will produce large-area FMM masks, suitable for the 8-Gen lines now being commissioned by the OLED industry to enhance production for IT displays. This new capacity will more than double DNP's FMM production capacity.

The LG UltraFine 27EQ850 OLED Pro monitor is based on a 27" 4K OLED dipslay (likely produced by JOLED) and offers a 60Hz refresh rate, 99% Adobe RGB and DCI-P3 color gamuts and a brightness of 200 nits.

The 27EQ850 is now shipping for $2,000.

The 27EQ850 is quite similar to LG's 27EP950B monitor , but with lowered brightess and no VESA DisplayHDR™400 certification, but is is cheaper by $1000.

KT&T, established in 2020 as a spin-off from INT Tech with an investment of $143 million, has developed an OLED microdisplay that achieved a brightness of 12,000 nits, which is the highest brightness OLED microdisplay ever developed.

The new panel is based on KT&T's own uNEEDXR technology, which is a direct-emission (no color filters) design. The display achieves very high brightness and high efficiency.

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

Researchers from the University of Cambridge, led by Dr Alex Gillett, have studied the effect of host materials (the dielectric environment) on the performance of TADF OLED emitters, and specifically how the dipole moment of the host material can affect the rISC rate of the TADF component.

The researchers tested several TADF OLED materials, and in some of these materials, the effect of different host materials can be quite dramatic. It is believed that commercial TADF devices could benefit from tuning the host and emitter combination to achieve higher performance, including a better efficiency roll-off as conversion of triplets into singlets can be accelerated.

Huawei's Smart Vision VR Glass is a headset that offers a 120-inch virtual screen, and is based on dual FHD OLED microdisplays with 480-nits of brightness. The headset connects to a smartphone or computer and does not include any CPU, storage or battery.

Huawei will start selling the Smart Vision VR Glass in December 0222.
