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.

China-based Red Magic announced a new gaming monitor, based on a 49-inch QD-OLED panel (produced by Samsung Display). The Magic Realm full specification is a 49" 240Hz 5120x1440 curved (1800R) display, and it offers FREE-SNYC and G-SYNC compatibility and built-in 5W speakers.-

Red Magic did not yet reveal the price or release date of its QD-OLED Monitor.

In January 2023, Samsung unveiled the Odyssey OLED G9, featuring a 49-inch 5120x1440 240Hz 0.03 ms GtG response time ultra-wide QD-OLED panel.

Samsung now officially started accepting pre-orders for the new monitor, pricing it at $2,199. Samsung will start shipping the monitor on June 25.

Canon announced that it has developed new perovskite quantum-dot inks for use in next-generation displays, with improved durability and potential for application in high-image-quality displays.

Canon's new perovskite quantum-dot inks are cadmium free, and thanks for Canon's proprietary technologies, the QDs feature protective shell that enables high lifetime and efficiency. Canon's QDs are about 20% more efficient in light converstion compared to standard QDs, and cover 94.4% of the BT.2020 color gamut - higher than regular InP quantum-dot inks (that usually cover around 88% of the same color gamut).

China-based BOE has demonstrated a new 4.7" AMQLED display prototype, a self-emissive QD based panel.

The panel offers a resolution of 1440x2560 (650 PPI), a color gamut of 85% BT2020 and a high contrast ratio (rated at 10,000,000:1).

Samsung Display demonstrated its latest QD-OLED displays, in TV format (77-inch) and also in monitor formats. SDC's QD-OLED panel display won the SID Display of the Year award, and is indeed an impressive display. The company's latest QD-OLED panels offer new OLED materials, new optimized algorithms, and a maximum brightness of over 2,000 nits.

Besides the 77-inch TV, Samsung also showed 34-inch QD-OLED monitors, and 49-inch QD-OLED monitors with a ultra-wide aspect ratio (32:9).
