Hi Ferenc
I did some paper-pencil calculations on what we know about these displays. I put it here: https://redmine.libresilicon.com/projects/maskless-lithography/repository/43 /revisions/master/entry/JBD_uLED.txt Conclusion: it may even work.
Fantastic work! Well done!
Some questions regarding the topic:
What can we know about the uLED technology INL developed? I found not too much except it produces good-looking neuromorphic spiking behavior at very low current densities... What are the key parameters (wavelength, optical power output, resolution, defect density, uniformity, WPE)? Is this data public, or INL handles it proprietary? What about IP things (patents by INL, etc)?
It's infrared they're generating, not UV light, unfortunately, so if we could use the uLED displays from JBD we would have a head start. They're hardening polymers with a laser and use them as a wave guide for light in the infrared spectrum.
JBD's display technology is proprietary and patent-encumbered. What aspects does it have on adapting it as the basis of our stepper? What INL (or their government) will do if they realize it can be used not only as a display?
Considering that JBD is a Chinese company, not a European one, based on my past experiences, they might make the uLED display way too expensive for us to be competitive and might start developing and selling their own steppers, which will suck and their business attempt will fail. I'm much less worried about the government, when it comes to Chinese companies, they're not the same maniacs like the ones in Brussels right now trying to ban end to end encryption. Haha When it comes to INL, as well as when it comes to JBD, we first have to do our homework and select the most suitable component, after that we will have to do some guanxi building and convince them that it's better to work together and cooperate instead of trying to fuck each other over. Building up loyalty among partners is an ancient old Chinese tradition, so is fucking each other over BTW :D
