TianMa starts producing rigid and flexible AMOLED panels at its 6-Gen fab in Wuhan

Apr 25, 2017

TianMa Micro-Electronics announced that its 6-Gen LTPS AMOLED fab in Wuhan, China, is now starting to produce panels. This is the first 6-Gen AMOLED line in China to enter production. The new fab will produce both rigid and flexible OLEDs.

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.
