This seems like a dumb question, but why is it that SDE (screen door effect) is dependent upon resolution? It seems to me like extremely high resolutions would force SDE to be solved but that SDE could also be solved by making "fatter" pixels at the same PPI. The cheapest way to do that would presumably be some slightly diffusive layer on top of the screen that diffuses by about 1/2 the distance between pixels. This…
The diffuser will blur the image, the opposite of what you want. Higher resolution screen with upscaled input does not sacrifice clarity for blur/no SDE. Upscaled input won't have as high detail as a higher resolution input, but the performance gains of the upscaled input far outweigh the negatives.
Whenever we crumple our eyes up to squint we're creating a diffraction grating that works a treat for the myopic amnesiac I am when without my spectacles.
The ground glass of the focusing screen in my Nikon is diffuse. This particular diffusion assists with guaging the lens focus, bit only for smaller apertures than f/2.0, so that expensive 85mm f/1.4 prime lenses need autofocus. Dunno how I managed for two decades professionally before the digital switch rendered great optics practically redundant*
So what's preventing the projection of the high resolution display information into a kind of focusing screen like the old fashioned Single Lens Reflex cameras won the market with in the fifties and sixties?
Is it more physical constraints of the imposition of the display into the field of vision for infinity focus?
If long ago my amateur interest would have carried my thinking further, sadly I have no applicable reading even on the subjects, so forgive me if this is a beginner supposition in error.
I certainly see the opportunity to directly encourage the hardware development, even if the equipment will be unwieldy to use, even more so than today, for specialist fields such as fabric design and magazine printing. I have been involved in the latter for the entirety of my career, two decades of that running the company I hoped would open up enormous markets and that field even defenestrated Google in 2004, leading to the most epic narrative and pivot story if I manage to get things kicking again. * Surely there is a very good overlap between the current generation of customers for whom the budget simply isn't the obstacle, and the same customers who will allocate whatever you want to charge in the future, if you can deliver real advantages? I'm optimistic about VR, but not in any kind of short term horizon. I founded my own business on a thirty year plan.. that still could be met, and made decades one and two, kinda just the latter. Maybe this is what we all need: real long term benefit analysis and commitment. This isn't a factor of the youthfulness of the Valley to which short termism is often ascribed,when flighty CEOs are discounted, I was very young and junior by a generation and some to my co-founder, when I realized how I had found my calling. Surely the VR sector has plenty of similar thinkers young enough to put such time to their dreams?
*I kinda continue a bit in my profile, where I may be more bold soon. I welcome any feedback or inquiry, I may be less than the epitome of clarity when I come close to professional engagement with ideas I can't believe.. the industry hasn't destroyed my hopes because of politics not technology, not yet anyhow..
