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.
My understanding is that display-port is quite open in that there is no per-device fee for implementing it, I suspect you still have to be a vesa "member" to get a legit copy of the spec.
Honestly at this point I consider VESA one of the good guys. At least compared to the alternative, spits, HDMI
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.
These are now commercially available and my kids wear them. It's a basically invisible pattern of dots, not a visible blur, and both have stopped the progression of their myopia in their tracks.
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.
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.
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.
This is interesting info. I guess you can get higher angular resolution if you are able to turn off the screen fast enough, and turn it on at the correct angle. Of course, you won't be able to light all voxels during the same revolution, but perhaps that is not a problem.
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.
yep, definitely a bug - seems like with when getting a winning of aces after the second deal. interestingly if you get a pair of jacks you get your winnings correctly. guessing aces are low.
