Eyestrain, blue light and the future of work-at-home business! Here is a suggestion that may or may not have been proffered elsewhere, in similar or partial form, as presented in this essay.
Chapter 1: Bundled Fiber
A three dimensional array of bundled fiber, possibly square strands, if practicable for production, otherwise round as normal fiber optic strands, forms the screen for this TV notion.
In production, very narrow layers of mirroring LCD are distributed at pixel distances along the length of each fiber, parallel to the viewer. Three color RGB lasers reside at the terminus of one side or perhaps both sides of each strand in the 3-dimensional array. This means the light for any particular mirror passes through the length of the strand from the side of the screen. Each strand has a segmented backing LCD layer that can be turned on and off in sequence with the mirroring LCD layers along the fiber. Microscopic gold filaments run through the screen allowing turn off/on activation of LCD mirrors in both planes in sequence to produce an image. Gold can be strung extremely thin, so this is not quite as expensive as it might seem. Perhaps other metals or substances could substitute as long as they are thin enough so as not to interfere with the image. When the LCD layers are off, the fiber would be transparent up to the current turned on mirroring surface, allowing the laser to shine to the target pixel.
Once a pixel laser light burst occurs you would have a reflection back effect that would be muted by the constant turning on of each LCD mirror in sequence as the beam illuminates pixels across the screen, moving ever closer to the laser source. This could be a problem, or it could be canceled out to the human eye in viewing against the backdrop of the entire image. The eye is always looking at a symphony of light bursts fixed on the eye for its fifth of a second duration. It might also work better if the laser reverses, lighting pixels closest to the laser first and moving to the end of the strand.
Now the image is projected left to right, front to back, or perhaps both left and right and front to back from left and right elements. This is done quickly enough for the human eye to see all illumination as one image using a more natural illumination (we suppose) than typically gotten from an LCD screen. The side lasers would likely not be LED lasers.
Starting in pixel array (0,0,0) and sequencing back through pixels (0,0,n), the first parallel mirror in the strand is activated with the backing mirror activated at the same time. Each backing mirror is deactivated as the next backing mirror is activated through the depth of the array. So the eye sees the first layer then the second and so on in depth illumination until the end of the depth row is reached. Below/or above on (1,0,0) and the following x-axis optical cables, this is happening simultaneously. The illumination goes on all the way to the right of the screen or to the middle of the screen if lasers are arranged on both sides. The eyes see one 3-dimensional image without back lighting. Might this have a more benevolent effect on the eye, if the correct lasers are used off-screen? For a printed screen, only the surface layer would have coloring and the rest of the array would be monochrome white or black or some other pagination color. Perhaps we could use 7 color lasers to get a more natural mix of colors, if the expense were not too great. To avoid great expense, by breaking up the output of a larger laser beam such that only part of it passes to the particular strand at the right time, large lasers could be used to service multiple strands of optical cable. In effect, an LCD mirror grid would operate in sequence at the laser output as well, allowing the appropriate light only to each strand at one time. (This might cause some overheating problem that would need dealing with at the laser apertures.) Some curving surfaces could be used to get the red, green or blue light to the particular fiber strand. Alternately, nanotechnology will allow manufacture of lasers that are not LED in nature, and might give a better optimal light control than LED. On the other hand, LED lasers may work just fine as they are in this type of configuration without back lighting.
I am assuming that this sequencing of depth lighting will not have a distorting effect upon the human eye. I am not positive that it will not. The effect on the human eye of a two dimensional screen is firmly established. Otherwise this uses the same technique of mixing color to achieve an image as regular television. I would suppose when reproducing real images in 3-dimension, you would simply use multiple television cameras synchronized in time, in a Cartesian grid coordinate pattern, that would then be stored in such as a manner as to reproduce the image. The synthesizer would need to know precisely where the cameras were and the angle of the lenses at time of recording. These cameras would be standard television cameras without any of the usual holographic techniques. My array of cables should be able to reproduce this using standard television techniques with the exception that there would be the depth overlaying, which I hope will not cause visual distortion in the human brain. If it does, you can scrap this idea as useless.
It is a question whether the surface of the screen will need LCD mirroring to block the beam moving to its target pixels. Probably the surface will need LCD mirroring. The whole effect is based upon light scattering from the depths and across the screen. A pure ray of laser cannot be seen by the eye without scattering when not in direct line of sight, but there will likely be scattering down the strand in transmission. Perhaps all this scatter would cancel out to the viewer’s eye, perhaps and likely not. There is the question of the depth of rays coming at the eye from the Cartesian z-axis. Obviously, the pixels would have a real time delay in light transmission time to the eye. But there would be the mixing intensity that might have to be controlled in a manner other than when an eye views real light coming from surfaces on a object that are closer and farther away. This could be checked out empirically, if opticians do not know the answer deductively. I do not know the answer deductively.
There will be great overhead cost in production, but modern mass production techniques might still get the cost down to realistic pricing. And a richer world through better technology can afford higher prices if the product is worth it to the benefit of human health. Without health we have nothing.
Things get quite curious when the dilettante spends his time thinking up ways to make things better. Just the other day the idea came to me that a supersonic biplane might have better fuel efficiency than one wing. Are not biplane wings often thinner than single wings? And supersonic planes typically have thinner wings to reduce sonic vibrations. So I thought the wings would need to be set so as to eliminate the supersonic drag, to produce the effect of superior lift. I was thinking lift fuel savings. I checked the Internet to see if anyone else thought of supersonic biplanes. They have and it is under serious consideration. Oddly, to me at least at the time, the problem is that they have less lift than single wing aircraft. They save fuel by reducing sonic drag disturbances more efficiently. Huh! So will my 3-dimensional TV cause more eyestrain in supposing that it will cause less eyestrain? Or be a complete blur? Before embarking on the idea, this matter should be cleared up to avoid a fiasco.
Using work-at-home sites would be great for getting extra work from the elderly at conditions suitable for their weakened condition, greatly alleviating the burden of retirement benefits on society. The elderly are best left working at a reduced rate commensurate with their weakened condition to keep them from wasting away before their time and stressing out the young financially. Of course, the young would benefit from at home work as well. You eliminate traffic congestion, the need to dress up and shower under pressure, more time for sleeping, better able to get a meal in if you oversleep, better able to deal with small children and work at the same time. Improved utilization of the workforce would allow larger housing units for offices separate from kids, but able to monitor kids with cameras and microphones or just within earshot. Older kids could study at home, and work part time with the parents to help mom and dad pay the bills, a family working unit similar to a family farm. This is good for society. Anything that helps this is a benefit. Improved video monitors are important in this respect.

My current biography and contact links are posted at . My writings include essays, poetry and dramatic work. Though I write poetry, my main interest is essays about the panoply of human experience and knowledge. This includes philosophy, science and the liberal arts. Comments, reviews and critiques of my work are welcome. Thank you for reading my book.
A preface states the intent of the essay. Chapter 1 lays out the 3-D pixel bundle that forms the screen. Lasers send down light to a given turned on mirror with a turned on backing mirror. This creates a light burst at that pixel determined by RGB lasers on the screen sides. The next LCD mirror turns on and the next pixel receives a light burst. Light scatter is the source of illumination to the human eye. This works down a z-axis (depth) as well as across and up and down (x & y-axis) as with a normal TV image. Some problems with the human eye watching this image are mentioned, whether it is actually a good idea, and the cost of the project is brought up as well. Some comments on the benefits of superior screens for at-home work are mentioned, how they will help pay for an elderly population and make a superior work environment for the young, a family high-tech farm business, in effect. Hope you enjoy the short read.
