Sinora: Samsung Display buys OLED technology from Germany

,We make OLEDs better“That was the motto of the company Signora, with headquarters in Bruchsal in Baden-Württemberg. Samsung’s display subsidiary is clearly convinced of their work on materials to improve organic light-emitting diodes and, according to Bloomberg, to Signora. Equivalent to 300 million US dollars.

Although the acquisition has not yet been publicly announced, noted Bloomberg writer Mark Gurman is apparently certain that that his sources are correct, According to these, Samsung Display is said to have paid approximately US$300 million for Signora GmbH and thus acquired its technology for OLED displays, but not its employees.

TADF emitter for more efficient display

Specializes in the development of Signora types of blue and green emitting materials Thermally Activated Delayed Fluorescence (TADF) Distinctive and introduced a fluorescent blue emitter in March 2020, which is said to work 15 percent more efficiently than the previous ones. The company marketed the new material under the name Cyblue Booster, After the presentation in January 2021 SayUltimateGreen, A red counterpart has not yet been presented, but is also possible on this basis.

,TADF technology can be used efficiently for red, green and blue all OLED colors, a feat not achieved by any other technology so far.‘ Sinora explained on its website, adding: ‘TADF combines the benefits of phosphorescence (high efficiency) and fluorescence (lifetime)“. Should reduce the power consumption of high efficiency OLED displays compared to previous solutions.

The pixels of such an RGB OLED display consist of a blue, a green, and a red subpixel. LG, on the other hand, relies on white OLEDs and WOLEDs with color filters. With Samsung’s new QD-OLED technology, only blue OLEDs are used as the backlight; Here quantum dots are used as color filters to generate green and red light.

Only technology has captured

Samsung and LG had previously invested in Synora. as OLED information Reportedly, Synora recently ran into financial difficulties and laid off its entire workforce a few weeks ago as part of the transaction. So Samsung only gets technology from a company that has over 700 patents on its flagships.
