QuantumDots-Info, a new knowledge hub to focus on quantum dots technologies for the display industry

Metalgrass has launched a new knowledge hub, QuantumDots-Info.com. Our new site focuses on QuantumDots technologies for the display industry. QDs are already used in many displays, and it is likely that the future will bring us more types of QD Displays, including QDEL, QD-OLEDs and QD-MicroLEDs that use quantum dots to convert blue light to red and green.

QuantumDots-Info brings you daily news, commentary, resources and updates about QDs in the display industry. You can subscribe to our weekly QD display newsletter here - and if you have not done so already, be sure to also subscribe to the free monthly MicroLED newsletter!

STRATACACHE to build the first MicroLED production line in the US, mass production expected by 2023

Global digital signage solution provider STRATACACHE is embarking on a project to construct a microLED display production line in Eugene, Oregon. The company aims to start production in this fab at around 2022-2023, with plans to adopt these microLED displays in its own solutions.

The new factory (E4) will be a complete microLED production line, from epiwafer (on 300 mm silicon wafers), through transfer process and to final module assembly. The company plans to produce a wide range of displays, from tablet-sized panels to large-area displays. Some of these displays will be flexible and transparent as the company sees a market demand for such technologies. The yearly capacity of the E4 is expected to start at a 1 million square meters per year.

A discussion on MicroLED efficiency - microLED displays

This article is the second article in a short series of articles that discuss the efficiency of microLED displays. Our previous article discussed the quantum efficiency of microLED chips - with a conclusion that these can be quite efficient.

PlayNitride high-brightness high-density passive-matrix wearable Micro-LED prototype (SID 2019)

This article will look at the entire microLED display, and also compare it to current LCD and OLED displays. After all one of the main advantages of microLED displays is the increased efficiency (and brightness) compared to current displays. Most people assume that indeed microLEDs are much more efficient than OLEDs and LCDs.
