Samsung is investigating combining quantum dots with OLED for televisions

Samsung is again developing OLED technology, the company has confirmed. In a research project, the company is trying to combine the quantum dot technology it uses with its QLED TVs with OLED, possibly using blue OLEDs.

The CEO of the Visual Display division confirms to ZDNet that Samsung is developing OLED televisions again. He also reports that Samsung wants to combine quantum dots with microLED technology. It was already known that Samsung sees a future in quantum dots and microLED, but that the company is again investigating the use of OLED was not yet confirmed.

Samsung got rid of OLED in 2016 because LG owns the patents on the use of white OLEDs. As a result, Samsung had to limit itself to the use of RGB OLEDs, the quality of which deteriorates because blue, green and red do not wear evenly.

In February, the rumor appeared that Samsung had shown OLED TVs with blue OLEDs during CES. Samsung would use a quantum dot layer and color filters to display red and green. Samsung denied this rumor. Compared to red and green, blue OLEDs are the weakest link in terms of lifespan and efficiency.

But Samsung has invested in the company Cynora, which is developing the OLED technology thermally activated delayed fluorescence, or TADF. Cynora began manufacturing blue tadf-oled emitters in late 2017 that would negate the shortcomings of blue oleds, OledNet wrote. Incidentally, LG also invested in Cynora and the company wants to produce green and red TADF emitters at the end of 2018 and the end of 2019, respectively.
