  • Based on this pin configuration, there’s only two dedicated power pins, which isn’t very good for large wattages. The rest are twinax signal pairs separated by ground to reduce crosstalk.

    Usually when connectors are designed for power delivery, they’ll use bigger contacts to reduce the contact resistance (signal contacts tend to be small so you can fit more of them in the same space). I’m guessing the original DP connector form factor wasn’t made with such high power in mind, so it would make a lot of sense to use the spare signal pins for power delivery in this case. Running too much power through too few small pins can damage the contacts, by either by instant-welding the contact surfaces or by overheating the connector (see NVIDIA GPUs) ((also high voltages can cause arcing, which even in the best case will seriously degrade any connector)).

    Take all of this with a huge grain of salt cause I just learned this stuff like a month ago, and my department has nothing to do with any of it. Just though someone might find it interesting.












  • One of their older color products is a traditional B/W screen with an RGB filter over the top. The problem with this is the filter tends to make everything way darker and muted than it should be.

    They are also working on newer ACeP screens that use multiple colored dye and pigment particles in the same capsule. By swapping the colors around with specific electric waveforms, they can control what the color looks like from the front. The downside is that this color swapping often takes several seconds to produce the correct color ((also the color gamut has a lot of holes))
