Columbia engineers invent a flat lens that exclusively focuses light of a selected color—it appears entirely transparent until they shine a beam of light with the correct wavelength onto it, when the glass turns into a lens.

Researchers have designed smart, colour-controllable white light devices from quantum dots, tiny semiconductors just a few billionths of a metre in size, which are more efficient and have better colour saturation than standard LEDs, and can dynamically reproduce daylight conditions in a single light
Why can microLED technology can help narrow the energy gap in electronic devices? The first slide shows the battery gap- Ahmed (Intel) has collected data by year showing that power demand of phones far exceeds the power supply level of batteries, creating a "battery gap" which ...
As microLEDs inevitably shrink in size, the micro-bumping requirements for the microLED dies becomes more challenging. Direct wafer-based printing based on gravure offset techniques offers a promising solution in this regard. Indeed, this is another field where printed electronics can play a role.
The three themes are closely linked since QDs can be digitally printed as color conversation materials atop blue microLEDs to enable wide color gamut RGB uLED displays without requiring a separate transfer step for each color.. This is an important technology as it simplifies the manufacturing step for microLED and thus removing a major hinderence.
Phosphors or QDs for color conversion in LCD and microLED ? Which will win? This is an evolving technology space to watch. Here, it is shown that phosphor technology is evolving, enabling not just red but also green narrowband color conversation with small particle sizes compatible with microLEDs
