Unfortunately, DisplayPort and HDMI specifications are kept private unless you're a paying member. I've successfully implemented DisplayPort 1.2 in an FPGA from specification documents I found, but I could never find the specific

There's a husband and wife team of optical scientists who have been studying myopia and theorize that high contrast across the retina signals the eye to elongate which leads to myopia. "Their big breakthrough in understanding myo

LOL, what? There are indeed 3D displays with eye tracking built in that do this. I was just at Display Week expo last week and saw a handful of new models, and they've been around for years. Innolux booth at Display Week: https:&#x2

The big push is currently towards microLED displays because of the high brightness and fast modulation speed. Yield is not yet good, and there's difficulty in growing all colors on the same substrate. Picking and placing different co

I work on VR/AR headsets where there's a drive for higher refresh rate displays to do things like multiple focal planes with the extra frames.

Standard displays are 60 Hz. You need a much higher framerate because not only do you want 60 frames a second, but you also want some number of frames per angular rotation. For 1° of angular resolution, you would need: 360°*60 Hz = 21,600

When I was in the Navy, "shipmate" was a negative term because you only heard it when someone, most likely a khaki (senior enlisted or officer), didn't know your name and wanted to chew you out. "Hey shipmate! Your hai

You can get 720p pico projectors off the shelf, but to do 8K, you have to make a custom design with faster laser modulation.

What exactly cost so much? You can build a retinal display using a $200 off-the-shelf laser projector if you turn down the power and add less than $100 in lenses. I've done it, and I've even managed to get it up to 8K resolution

In an interview, Jeri Ellsworth stated that when she was at Valve around 2012, they were exploring all types of near-eye displays for use in their eventual VR headset, and one of the displays they tested was a laser retinal projection displ

That is a failure that could potentially result in damage to the eye. MEMS mirrors have built-in angle sensors, and when these report that there's irregular or no detected movement in one or both directions, the lasers are turned off.
