QD-OLED displays - Page 12

In February 2018 it was first reported that Samsung Display is developing TV panels based on hybrid quantum-dots and OLED architecture (QD-OLED). Samsung later confirmed it is developing such technology, but with no immediate plans to commercialize it.

ETNews now reports that Samsung is now working to establish a pilot 8-Gen line for QD-OLED production. ETNews says that Samsung is collaborating with both Canon Tokki and Kateeva to develop the production equipment - apparently the OLED layers will be evaporated using Canon's machines while the QD filters will be deposited using ink-jet printing equipment made by Kateeva. Samsung aims to finalize the production line by the second half of 2019.

In February it was reported that Samsung is developing a hybrid Quantum-Dots OLED technology for its future TVs. This report was soon denied by Samsung's Visual Display Business VP, Han Jong-hee, who said that Samsung is sticking to its two-track strategy for premium TVs, namely QD-LCDs and Micro-LEDs.

Today Samsung's Han Jong-hee again says that Samsung has no plans to produce an OLED TV any time soon - but he does confirm that the company is researching a way to combine QDs with OLEDs. According to our information, Samsung's main R&D initiative use blue OLED emitters and blue light to white light conversion using quantum-dots, combined with color filters (QDCFs) to add red and green colors.

Last week we reported that ETNews claims that Samsung is developing a hybrid Quantum-Dots OLED technology for its future TVs.

Today Yonhap News reports that Samsung Visual Display Business VP, Han Jong-hee, denies this story, saying that Samsung sticks to its two-track strategy for the high-end TV market, developing both QLED (quantum-dots enhanced LED LCDs) and Micro-LED TVs. Han further says that Samsung will start selling its Wall Micro-LED TV in August 2018.

ETNews posted an interesting article, claiming that Samsung Display is developing a new TV technology that combines OLED emitters with quantum-dot photo-luminescence materials. The basic idea is to use blue OLED emitters and then convert the blue light to white light using quantum-dots combined with color filters (QDCFs) to add red and green colors.

This seems to be a rather complicated design, but it could be much easier to produce compared to a true RGB OLED TV, as there is no need for precise OLED patterning. This is similar to LG's WRGB OLED TVs which use a white OLED source (made from yellow and blue emitters) and color filters on top.

Hyperfluoresence and TADF OLED emitter developer Kyulux and quantum-dot developer Nanoco announced that the two companies will co-develop a future-generation hybrid OLED / QLED display technology that combines Kyulux's hyperflourescent emitters and Nanoco's heavy metal free quantum dots (CDQDs).

Kyulux and Nanoco say that future displays based on this technology will have superior qualities compared to existing displays - high degree of brightness, energy efficiency, color purity and low cost.
