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.
PCB layers are the copper layers within a printed circuit board, laminated between or onto layers of conductive material. These layers are stacked to enhance the functionality of electronic devices. This article explores the concept of PCB layering, the various types of layers, and their benefits.
Flexible electronics have enabled the design of sensors, actuators, microfluidics and electronics on flexible, conformal and/or stretchable sublayers for wearable, implantable or ingestible applications.
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

How to overcome the traditional limits of LDS (laser direct structuring) to metallize 2D and 3D objects made from all kinds of surfaces?
It is incredible to see the progress that organic semiconductors (OSC) have made over the past 15-20 years. Ian Jenks explains in this short 5-min presentation how they are removing the long-existing barriers to adoption of OTFT technology.
Gallium-Indium-Tin is an interesting material for stretchable electronics. It can be formed into a non-toxic RoHS-compliant gel and applied to almost any substrate to form stretchable conductive metallizations and circuits.
Screen printing never ceases to advance and is entering into ultrafine line printing territory. FERNANDO ZICARELLI explains in this short 5-min talks important considerations to achieve fineline printing and further push the resolution down:
Quick turn PCBs are designed, fabricated, and assembled swiftly, ensuring tight schedules and deadlines are met, even for high-volume orders. This article investigates the quick turn PCB process, highlighting its benefits, stages, and how it guarantees quality within a short turnaround time.
Here, the additive nature of the process means that the production process is environmentally friendlier and does not involve etching chemicals. Furthermore, the digital nature of the patterning (inkjet printing) means that designs can be changed faster.
We first discuss emerging and existing applications for ultra fineline screen printing, outlining how evolution of screen printing can unlock various electronic applications. Next, it will review other printing technologies extending the linewidth resolution to sub-micron range
Printed Circuit Boards (PCB) form the backbone of electronics, while Printed Circuit Board Assemblies (PCBA) complete the circuit with components – this article explores the differences, roles, and implications in hardware design and manufacturing of PCBA vs PCB.
