In July 2023, Samsung officially launched the 83" 83S90C, the company's first TV to use LG's WOLED panels, following several years of negotiations and hesitation by the Korean rivals.
It was assumed that Samsung's total orders from LGD will be limited (as the 83-inch are expensive and not highly popular), and according to UBI, the total number of panels that LGD actually shipped to Samsung is only 'several thousands'.
Germany-based Credoxys has successfully completed its second funding round, led by deep-tech VC LIFTT and Melchers Group. The company says it will use the funds to commercialize its p-dopant technology in both the Korean and Chinese markets. The company already validated some product candidates with industry partners, and these are ready for customer qualification.
Credoxys is focused on developing novel materials for both the p- and n-sides of OLEDs and organic solar cells (OPVs). The company says its newly developed p-dopants surpass current standards by exhibiting extremely low absorption of visible light and low pixel cross-talk. The materials enable the doping of hole transport materials with deep HOMO levels, making them particularly suitable for phosphorescent blue OLEDs.
Universal Display is progressing with its blue PHOLED material, and earlier this month the company said it is on track to introduce the new material commercially in 2024. During a company seminar, UBI's Daejeong Yoon updated that according to their latest information, Samsung Display has decided to adopt a blue phosphorescence material in the second half of 2025 - a year later than expected.
Samsung is calling the new material stack B1, and it says that the new stack will increase the efficiency of its OLED device by more than 65% (which seems to be rather too much, maybe it means 65% of the power consumption of the current stack). UBI says that the blue OLED still suffers from low lifetime - the lifetime of the blue PHOLED stack is only 55% of the lifetime of its current fluorescence-blue stack, but regardless of that the company will introduce it commercially due to the power consumption efficiency.
According to reports, Kateeva's QD-OLED printing project saga is not over. Samsung Display tested the company's latest printers, but these failed the tests and Samsung Display will not but these printers. SDC planned to replace the currently-used Semes' printers, which also suffer from low performance.
Samsung Display is also not committed yet to expand its QD-OLED production lines, which means that in any case it does not need to buy new printers for production expansion. Earlier reports suggested that SDC wanted to upgrade it current capability for higher density (to reach 8K TV printing), so this may be the reason behind the testing of Kateeva's new printers.
