OLED-Info: the OLED experts

OLED-Info has been the leading international OLED publication for over 10 years, with a readership of more than 120,000 professionals a month. We provide a multitude of services to the OLED market based on our extensive and up-to-date knowledge hub and close ties with industry leaders. Our consultancy services include market outreach assistance, display brokerage, business development, financial intermediation and more.

An OLED uses organic semiconductors to create thin light emitting panels. OLEDs are used to create thin, beautiful, flexible and efficient display and lighting panels, and are the future technology of choice.

The Vivo S1 is scheduled to ship by the end of July 2019.

HiSense set to launch its dual-LCD TVs to compete with OLEDs

In January 2019 China-based Hisense announced its dual-LCD ULED XD panel, that includes an monochrome inner LCD panel that acts as a two million dimming zones layer to boost the contrast.

In a trade show in China, HiSense demonstrated this panel again, and is apparently close to launching it as a product. The model number will be U9E and Hisense plans to sell it for CNY 17,999 (around $2600) for the 65" 4K model.

Visionox confirms it supplies the prototype foldable and embedded-camera OLED displays to Xiaomi

In January 2019 Xiaomi unveiled a new prototype smartphone that uses a tri-foldable OLED display. The company did not disclose much information, but a report from Taiwan suggested that the OLED supplier for this prototype was Visionox.

In an interview with China Daily a Visionox VP confirms that Visionox supplied the foldable OLED prototypes to Visionox. He also says that Visionox supplied Xiaomi with the innovative OLED displays with under-the-screen camera (seen in the video below).

New OLED gadget: TECNO Phantom 9

The Phantom 9 is a mid-range smartphone that features a 6.39" 1080x2304 AMOLED notch-type display, an under-the-display fingerprint sensor, a Mediatek Helio P35 chipset, 6 GB of RAM, 128 GB of storage, a micro-SD slot and a triple camera setup.

The Tecno Phantom 9 will ship by the end of July 2019 in India for around $220.

Here is Panasonic's wooden-cabinet transparent OLED prototype

In April 2019 Panasonic unveiled a transparent OLED TV prototype housed in a wooden cabinet. Here's a nice video showing the display in action:

Panasonic has been showing transparent OLED display prototypes and concepts since 2016. This specific prototype was designed by Scandinavian based designer Daniel Rybakken in collaboration with Panasonic Design Kyoto.

CSoT demonstrated new OLED display prototypes and technologies at SID DisplayWeek 2019

China-based display maker CSoT demonstrated several new OLED display prototypes and technologies at SID 2019, and this great new video shows these displays in action.

First up is a 31" 4K (3840 x 2160, 144 PPI) AMOLED that was produced using an ink-jet printing process on an IGZO substrate. The peak brightness is 200 nits and the refresh rate is 120 Hz. This seems to be the same panel announced in March 2018 by Joshua Printing Display Technology (established by CSoT and Tianma in 2016). The display has some noticable defects.

Researchers use reactive ion etching to create nanostructures that boost the efficiency of white OLED devices

Researchers from TU Dresden developed a new method to extract trapped photos from OLED devices. The idea is to generate controllable nanostructures with directional randomness and dimensional order. This method is said to significantly boost the efficiency of white OLED devices. The researchers report that it is possible to achieve an external quantum efficiency of up to 76.3%.

To produce the nanostructures, the researchers use reactive ion etching, a facile, scalable and lithography-free method. In addition to these advantages, the method enables to specifically control the topography of the nanostructures by adjusting the process parameters.
