What Display Daily thinks: You go to work, you manage budgets, and timelines, and you work towards milestones that are months and years away. That’s the day to day of being in the display business. The best I can do is to give you hope that there is more to life than this. Sorry, that’s a little dark.
But, everyone needs motivation. There is no better example of the opportunities available to radical thinkers in a mature industry than Nvidia. We know plenty about the company at Jon Peddie Research. So, what does that mean for displays?
QDs. Let’s start there and use the literature review below as a jumping off point. If you start with the notion that QDs are a display material, you can see that there is ample evidence they are much, much more than that. So, every point of development on QDs should be leading you to look at broadening your reach and that means extending your grasp which translates into something akin to Nvidia going from GPUs to AI data center racks, or whatever you want to call them.
I expect that the first quarter of 2024 will be a sobering one for advocates of next gen display tech because the price differential is nowhere near justifiable by the performance differential. That’s a pretty basic assumption that is easily borne by the features and performance metrics of, say, OLED versus everything else.
Given that LCD and MiniLED displays can be amped up and made competitive by QDs, you may want to think of things in a different way. I develop by next gen display tech around QDs, and then leverage my QD expertise to provide material support in new markets like bioimaging. GPU to AI. Obviously that’s not a strategy but it is an approach to making a pivot.
More importantly, facing challenges in the display market that don’t really seem to be about demand or macroeconomics, rather than rigidity of the display industry supply chain, and a less than agile approach to change, display makers may want to empty their mind and, you know, be like water, change their shape.
Maybe we are an entering an era of re=tooling, so to speak, changing your production lines to make new stuff using old stuff. Is there a transition from displays to optoelectronics? Yes, I believe there is for some, certainly in the mid=tier of the industry.
When it comes to the Nvidia analogy, the company saw the limits of a mature market, a kind of quarter to quarter drudge through supply and demand fluctuations, exactly as it is happening in the display industry. The company took what it had and invested in finding every avenue of opportunity to make it something else. GPUs as parallel processing monsters for AI applications with all the software and foundation tools needed to make that happen. A completely different universe to the one inhabited by the traditional graphics market.

The Nanotech Revolution of Carbon Quantum Dots in Bioimaging
A comprehensive review of Carbon Quantum Dots (CQDs), focusing on their green synthesis methods, characterization techniques, and applications in bioimaging makes some interesting points:
- CQDs are nanometer-sized carbon-based materials (less than 10 nm) with unique properties such as excellent biocompatibility, tunable photoluminescence, and versatile surface chemistry.
- Green synthesis of CQDs is an eco-friendly and sustainable approach that uses natural and renewable resources as precursors while minimizing the use of toxic chemicals.
- CQDs can be synthesized through top-down and bottom-up approaches. The synthesis methods influence their physicochemical properties.
- The core structure of CQDs is characterized by a highly disordered carbon network with predominantly sp2 hybridized carbon atoms.
- Characterization techniques such as TEM, SEM, FTIR, XRD, XPS, Raman spectroscopy, UV-Vis absorption spectroscopy, and fluorescence spectroscopy are used to study the structural and optical properties of CQDs.
- CQDs have gained significant attention in bioimaging applications due to their tunable photoluminescence, excellent biocompatibility, and ability to be functionalized with specific biomolecules.
- The review explores recent advancements in bioimaging applications using CQDs and discusses the future perspectives of utilizing CQDs in this field.
- CQDs have the potential to revolutionize medical diagnostics and biological exploration through their application in bioimaging techniques.
