Metasurfaces Enable Directional Emission And Enhanced Efficiency In MicroLED
A significant development in MicroLED technology has come out of a collaboration between Lumileds and Eindhoven University of Technology. The research team has successfully demonstrated a novel approach to improving MicroLED performance by integrating metallic or dielectric metasurfaces directly into the LED structure, resulting in dramatically improved light directionality and efficiency. This development addresses two critical limitations that have hampered MicroLED development: their relatively low external quantum efficiency (EQE) and their characteristic Lambertian emission pattern, which disperses light in all directions rather than concentrating it where needed.

Optimising Green LEDs For Near-Eye Applications
A common approach for producing commercial, high-current LEDs involves the inclusion of pre-well layers – these superlattices, featuring low-indium content layers, are inserted before the active region to aid strain engineering. However, research by a team from China has shown that removing these pre-layers ensures a better performance for green microLEDs for near-eye applications, as their absence trims piezoelectric polarisation fields in quantum wells and suppresses Auger-Meitner non-radiative recombination.

Enhanced And Directional Electroluminescence From MicroLEDs Using Metallic Or Dielectric Metasurfaces
Micro light-emitting diode devices (microLEDs) have the potential to lead the next generation of displays. However, their integration for achieving high brightness is severely limited by the challenge of their low external quantum efficiency (EQE). Another limiting factor of such devices is their Lambertian emission, which requires secondary optics to beam the emitted light in defined directions. To address these limitations, we introduce metallic and dielectric metasurfaces to improve light outcoupling efficiency and control the emission directionality of blue LEDs with micrometer size.

Improving The Air Stability Of Flexible Top-Emitting Organic Light-Emitting Diodes
Flexible organic light-emitting diodes (OLEDs) are promising light sources for biomedical applications. However, the use of these flexible devices has been restricted by their short shelf lifetimes due to poor ambient stability. Here, a long-lived flexible OLED is fabricated by replacing air-sensitive metals such as aluminum and alkali metals used as n dopants with silver. In addition, to achieve stable and efficient flexible OLEDs, we tuned the optical cavity length to the second-order interference maximum. The device design has simple encapsulation and leads to an improvement in the air stability of flexible OLEDs, which show a shelf lifetime of greater than 130 days, whereas the conventional structure exhibits degradation after only 12 days.

What Is Tandem OLED And How Does The Display Technology Work?
Tandem OLED may sound like Apple just invented another marketing term, but it’s actually an industry-standard technology that we should soon see adopted across the consumer electronics industry. Here’s what it means and why it’s a step up from conventional OLED. Tandem OLED refers to the use of two organic light-emitting layers, stacked on top of each other. The technology combines two layers of OLED pixels, each with its own red, green, and blue (RGB) subpixels. These layers work together or in “tandem,” allowing them to achieve higher brightness levels without stressing the organic materials nearly as much as a traditional, single-layer OLED.

Next Generation OLED Emitter Development – Industry Update
OLED emitter materials are the heart of the OLED device and the materials that make the most impact on the performance of the OLED display. Most OLED displays utilize red, green, and blue emitters. The efficiency of the current state-of-the-art commercial red and green OLED emitters is excellent. It is, in fact, close to 100% internal quantum efficiency (IQE), which means that you cannot improve much on the efficiency of the emitter itself (there's still work to be done on getting the light out of the device). Blue OLED emission is a completely different story - current commercial blue emitters suffer from very low efficiency, around 25%. This means that three-quarters of the energy goes to waste.

MicroLED is a technology that lights up screens on TVs and smartwatches. It uses very tiny LEDs, which are so small they act as individual pixels. This means each tiny light can turn on or off independently, creating images without the need for a large lamp behind the screen. Unlike OLEDs, MicroLED doesn't have organic parts that can wear out over time, making it last longer. This tech promises brighter and more high-contrast pictures than ever before. Since there's no need for backlighting, devices with MicroLED displays can be thinner too. And because it bypasses organic components, viewers won't see the same kind of image burn-in that affects OLED devices after extended use.

Patterned Surface Energy In Elastomeric Molds As A Generalized Approach To Polymer Particle Fabrication
We present a generic fabrication scheme to produce polymer microparticles with engineerable, complex shapes. The polymer particles are made from polyethylene glycol based hydrogels using a poly(dimethylsiloxane) (PDMS) molding technique. A simple surface treatment is used to pattern the surface energy of the PDMS molds, engendering the recessed wells in the molds with a higher surface energy than that of the surface. The contrast in surface energy causes hydrogel precursor to wet only the inside of the molds, creating isolated particles after curing with UV light.

Patterning Technique
Frequently used patterning techniques include nanolithography, nanoimprint, and micro/nanoprinting. Nanolithography uses lights, charged ions, or electron beams to transfer a geometric pattern from a premade photomask to a photoresist layer, which is coated on a thin film material or the bulk of substrate. The technique then uses a series of posttreatments to chemically engrave the transferred pattern into, or allow the deposition of new material in the transferred pattern upon the target material.

Thermomechanical Properties Of Elastomeric Stamps For Micro-Transfer Printing Applications
Micro-transfer printing (MTP) enables mass-transfer of wafer-level chips having lateral dimensions ranging from 3 x 7 um to 650 x 650 um to a nonnative substrate. This is accomplished with an elastomeric stamp containing micrometer scale posts that have been precisely defined using photolithography. MTP is highly parallel and is capable of transferring tens of thousands of devices in a single MTP operation. Transfer yields and placement accuracy, however, are dependent on the performance of the micrometer structured elastomer stamp.

MicroLED Explained: The Best TV Technology You Might Never Own
The basic concept behind MicroLED is that screens are built using LEDs so small (usually under 50 micrometers) that they represent individual pixels in the image. That's compared with the usual LED TV situation where far bigger LEDs are used in a backlight to light many hundreds or thousands of pixels at once. You don’t have to be Einstein to realise that making a screen where each pixel is its own light source gives you a self-emissive type of display, opening the door to peerless levels of local contrast, colour and general light control. Which should add up to gorgeously natural, detailed, and refined images.
