Both Asus and Philips announced new gaming monitors based on Samsung's QD-OLED panel. First up is the Asus PG32UCDM, that uses a 32" 4K (3840x2160, 16:9) 240Hz VRR 1000 nits (HDR peak) QD-OLED panel. The PG32UCDM makes use of a graphene film for heat dissipation.

The Philips Evnia 49M2C8900 is a high-end gaming monitor, that is based on an ultrawide 49" 240Hz VRR 5120x1440 QD-OLED panel. Other features include Adaptive-Sync, NVIDIA G-SYNC and AMD FreeSync support, HDMI 2.1 VRR and a 30 W  audio system. The Philips monitor will ship in September 2023, for around $2,100.

Researchers from MIT have devised a new method to precisely assemble arrays of quantum rods, using scaffolds made of folded DNA. Using this method, the orientation of the rods can be controlled, which is a key factor in determining the polarization of light emitted by the quantum rods array.

The method starts by attaching the quantum rods to diamond-shaped DNA origami structures, built at an exact size required by the device. The structures are then attached to a surface, where they fit together "like puzzle pieces". 

Poland-based QNA Technology, a quantum dots developer and producer, raised $4 million in its latest financing round,and the company is now preparing to apply for a listing at the Polish ASO NewConnect stock exchange for early stage companies.

QNA was established in 2016, and is focused on blue light (400-490 nm) emitting, heavy metal-free quantum dots. The company optimizes its QDs for two applications: electroluminescence display devices (QD-EL) and for microLED displays devices based on UV microLEDs.
