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 specification for anything better.
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 myopia occurred in 2008 when they studied a particular group of people who had a genetic form of myopia that’s very severe. They discovered a gene mutation that was causing the myopia." As a result, they patented glasses that blur your peripheral vision, and a trial has shown them to be more than 50% effective at reducing myopia.
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.
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 color LEDs onto the same panel is not cost effective. Red microLEDs are also not yet as bright as blue and green.
There was a push towards micro liquid crystal panels with laser illumination to create holographic images with depth. There are several startups still pursuing that, but the image quality isn't very good at the moment.
The latest advancement has been in the optics with moving to pancake lenses to reduce the length of the optical path from the display to the eye. The Meta Quest 3 has a smaller form factor than previous generations because of this.
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 Hz display. Liquid crystals can be modulated at KHz speeds, but you're not going to find associated driving circuitry to do that. It's not easy, and there's no demand for it.
A TI DLP DMD can modulate at those high speeds, and there's readily available driving circuitry for it. However, it's a small reflective based display designed for projectors, and you would then need a light source to reflect off of it.
MicroLEDs would let you increase your pixel pitch with fast modulation frequency, but the display area is still small at the moment because of low yields. You also need a custom chip to drive the microleds at the required high framerate.
Ended on a hand of: K J A A Q and did not receive the Jacks or Better $1 payout. According to a brief search about the rules of video poker, a pair of aces is considered better than a pair of jacks.
I'm a VR/AR developer, and here's my experience with trying to buy a Magic Leap 2 to check it out:
See the PR announcement that they're shipping. Go to their web site. Click "Where to buy". Go to the first link to "Insight US". Place an order. Get a call from a representative to confirm the order. Ask the representative to clarify that Magic Leap 2 is in stock and shipping. They responded "yes."
Wait a few days. Check on the status of my order: "Stock: 0", and the estimated ship date is just an automated date that increases by 3 whenever current date equals estimated ship date. Call up Insight US to ask is it in stock or not. They admit it's not in stock and won't be available until maybe December/January.
Call up Magic Leap (they surprisingly have a phone line to call) and ask their sales representative if anyone has stock. They respond they don't know and to try the second supplier. Ask them what the supplier's phone number is to confirm stock. They say they don't know and that supplier only communicates through e-mail. Supplier responds via e-mail, "of course we have stock! Place an order to get an estimated ship date." I'm doubtful.
So there you have it. Magic Leap 2 shipping now, maybe?
Wow, thanks for posting that link! I was able to find his paper, "The End of Myopia", and glasses patent which describe his theory of myopia progression and preventative solution. The patent describes a pair of glasses with tiny dots (<1 mm in diameter) spread uniformly across the lens except in the central 7 mm diameter. The dots reduce the contrast of your peripheral vision which inhibits axial eye growth, and the clear region allows the wearer to see normally in the center of vision.
The theory is that children are naturally far sighted which creates blurrier/lower contrast central vision and sharper/higher contrast peripheral vision. The brain interprets the higher contrast peripheral vision as a sign the eye is too short and far sighted, and the eye begins to grow. As the eye grows to the appropriate length, central vision experiences higher contrast and peripheral vision experiences lower contrast, and the eye stops growing.
If you degrade the peripheral vision's ability to experience higher contrast at all with these glasses, then the brain will never see a need to grow the eye.
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 haircut is unsat!"
I loved to ask my grandmother about this because she recalled listening to the original broadcast. She said the station would take commercial breaks to interrupt the story, and they reminded listeners it was a fictitious broadcast when taking these breaks. She didn't believe that anyone could be fooled by it, at least not to the extent that was reported.
