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.

Merck - printed red, green and blue OLED efficiencies are now comparable to vapor-processed ones

Apr 21, 2017

Merck is going to discuss its latest soluble OLED material performance at SID DisplayWeek 2017 next month. Merck will detail the printed device efficiencies, voltages, and colors.

According to Merck, the efficiencies of its soluble OLED emitters are now comparable to state-of-the-art vapor-processed devices. Merck will also suggest a move from an evaporated blue common layer device architecture to a printed blue.

LG Display is developing higher image quality OLEDs for broadcast monitors

Apr 21, 2017

LG Display announced that it developed an OLED display with a higher image quality and high color uniformity. LG Display says it is aiming to use these new OLEDs in broadcast monitors.

LGD says that the new displays feature a "Real Black" image. LG Display used various OLED and TFT compensation technologies to achieve this high uniformity and better image quality. LG Display will provide more information at SID DisplayWeek 2017 next month.

The EU launches a €4 million project to develop efficient hyperfluorescence TADF OLED emitters

Apr 21, 2017

The EU launched a new project called HyperOLED with an aim to develop materials and matching device architectures for high-performance, hyperfluorescence TADF OLED emitters. HyperOLED is coordinated by Merck, and the project partners include MicroOLED and the Fraunhofer IOF institute. This three years project received a €4 million grant from the EU.

These OLED emitters will be realized by combining TADF molecular hosts with novel shielded fluorescence emitters, targeting saturated blue emission of very high efficiency at high brightness. The project will also achieve efficiency gains through molecular alignment to enhance light outcoupling.

Samsung's Gen-7 A4 flexible OLED line to be ready by Q2 2018

Apr 20, 2017

According to reports from Korea, Samsung has started construction of a new flexible OLED fab, which will be called the A4 line. This will be Samsung's first Gen-7 line as the company is aiming to expand its technology gap over its upcoming OLED competitors who are all building Gen-6 line.

A Gen-7 line substrate is 1870x2200 mm in size - as opposed to 1500x1800 mm for Gen-6. This means that you can produce more displays per substrate and price per screen is lower. Scaling up evaporation OLED production is not so easy, but it seems that Samsung managed to solve its technologies hurdles - mainly the FMM metal masks and the LTPS annealing process.

Innolux is assisting Sharp with its 4.5-Gen OLED pilot line construction in Japan

Apr 20, 2017

In 2016 Sharp announced that it will invest $570 million in its OLED business, with plans to construct two 4.5-Gen OLED pilot production lines in Japan (or maybe China?) with plans to start low volume production in 2018.

Sharp is owned mostly by Foxconn, who also owns Innolux, and reports in 2016 said that the Foxconn aims to integrate Sharp and Innolux's display business, focusing on OLEDs and IGZO technologies. Innolux's honorary chairman now says that Innolux is indeed cooperating with Sharp on OLED R&D, and the Taiwanese company is supporting Sharp's 4.5-Gen OLED factory construction in Japan.

Red Gate: is there a problem with Samsung's latest OLED panels?

Apr 19, 2017

Samsung started shipping its Galaxy S8 and Galaxy S8+ phones in Korea, and some of the first customers are complaining that the display have a reddish tint - which did not go away even after correcting the color display settings. This issues was quickly labeled as "Red Gate"... will Samsung face a new crisis?

Samsung itself says that there are no quality issues - and that the problem can be adjusted. Customers are welcome to replace their device, though, at service centers in Korea.
