Samsung reports its financial results for Q2 2022. The company says that its QD OLED monitor displays were "well received in the market", and the company is raising its expectations for the QD TVs which will be released in Q3.
Samsung further says it is stabilizing the production yields of its QD displays.
QD developer Nanosys announced a partnership with functional polymeric film developer Nanjing Bready Advanced Materials Technology. The two companies started mass producing the world’s first line of completely air-stable, barrier-free, laminated quantum dot film components.
Nanosys says that the new xQDEF laminate film offers high quality QD color and brightness - in a lower-cost package. Nanosys hopes that the new film will unlock new markets for QD displays. Tier-one consumer electronics brands including Hisense, TCL and Vizio are expected to launch display products based on the new components in H2 2022.
Samsung Display announced that it has managed to increase its QD-OLED production yields to 75%. Previously it was estimated that its yields are around 30-50%.
According to the report, SDC's employees are not optimistic regarding its QD-OLED competitiveness with LG's WOLED and RGB OLED structures - and not just because of the low production yields. Initial reviews of the QD-OLED panels say that the contrast is now as high as other OLED displays with ambient lighting, and there are color issues due to the unique pixel arrangement. It is estimated that even with increase production yields, SDC will refrain from further QD-OLED investments until it will see market reaction.
Researchers from Japan's Hiroshima University developed a new technique to create efficient silicon quantum dots from recycled rice husks. Rice husk is a good source of high-purity silica (SiO2) and silicon powder.
The researchers created SiQDs that luminescence in the orange-red range with a high luminescence efficiency of over 20%. From the QDs the researchers created LEDs based on ITO glass substrates, using spin-coating to process the SiQDs.
According to reports in Korean media, Samsung is developing a new process which will allow it to reduce the thickness of its QD-OLED panels, by removing one of the two glass substrates - the one used for the deposition of the quantum dots conversion layer.
Samsung hopes that this will enable it to reduce production costs, and also reduce the thickness. Theoretically, a single glass substrate could also lead, in the future, to flexible or even rollable QD-OLED panels.
