Instructables has posted a step-by-step guide to creating your very own dot-matrix display out of not much more than a collection of LEDs, a few wires, some resistors, and a microcontroller. The ...

However, his latest video uses some a MAX7219 to create a 600 character scrolling LED sign. You can see a video of the thing, below. Spoiler alert: not all characters are visible at once.

And this "quantum dot LED" display tech being researched by QD Vision may be what does it. How does it work? The secret is in the electroluminescent colloidal quantum dots. I won't tell if you don't!

QLED advances how LED backlighting and color filtering work, while 4K (UHD) is determined by the number of pixels on the panel. As such, QLED technology can be used on 4K, 8K, or any other ...
