China-based Leyard Optoelectronics says it is starting to produce microLED large-area displays that use blue microLEDs and QD based color convestion.

Leyard uses Saphlu'x NPQD technology (it is a stakeholder in Saphlux), which makes use of a nanopore structure to deposit the quantum dots on blue microLED chips. Saphlux says that the nanoporous structure has a unique scattering effect, which enhances light conversion efficiency and the reliability of the quantum dots. The solution also provides a wide color gamut, good color consistency and high efficiency.

Quantum Dots developer Nanosys raised $50 million in its Series B funding, led by Fortress, Centerbridge and Kilonova.

The company says that the new funds will help the expansion of its QD for LCD project, and also accelerate the commercialization of its microLED and nanoLED display technologies.

DSCC says that over 500,000 QD-OLED TVs will ship in 2022, offered by both Sony and Samsung. Shipments are expected to grow and reach 1.5 million units in 2026.

The main limitation for QD-OLED TVs will by Samsung's production capacity. In 2023 the company will add 49-inch monitors and 77-inch TV panels, as SDC will start using Multi-cut Mother Glass (MMG) technology.
