MicroDisplay Claims Progress Toward Elusive LCoS 127
zajaco0 writes "USA Today posted an article that talks about the LCoS (liquid crystal on silicon) technology that is being researched for the next thin, big-screen TVs. Big companies invest millions of dollars researching this technology and none of them seem to be making any headway. The companies who have this project on their failed list include Hewlett-Packard, Toshiba, Intel, and Philips. MicroDisplay seems to be making some progress though, says the company's CEO: 'After 22 designs, 320 man-years, a 50% staff of Ph.Ds, and $50 million, you end up with a design that works.'"

But if the new LCoS units are really expensive and thus become the "must have" for wealthy techno-geeks, then the sales of televsions from the current technologies should suffer as a result, which in turn should lower their prices.

On a related note, Toshiba's SED making progress (Score:5, Informative)
Apparently things are going well enough with the new factory that Toshiba is stopping plasma-panel production, and staking its future on SED TV's.
SEDs are like CRTs, in that they use electron guns to shoot electrons across a vacuum at a phosphor scren to generate light. The difference is that SEDs have a semiconductor-based electron emitter at each pixel. This allows the screen to be flat, shallow (a few centimeters) and relatively lightweight, while preserving the fast response, brightness, and wide viewing-angle of regular CRTs. Also, somewhat surprisingly, SEDs are significantly less power-hungry than plasma panels or even big LED screens.
Toshiba and Canon have built a factory to start building these TVs, and apparently they are going to be trickling into the market toward the end of 2005. I can't wait!

But CRT's aren't perfect. (Score:2)
However, CRT displays do have a couple of major downsides:
1. They tend to use a LOT of power--a 19" CRT display uses about 3-4 times the power of an LCD of similar diagonal size for viewing area.
2. There is considerable trial and error in fiddling with the monitor geometry controls to get the display to look just right. With LCD's, plasma, and soon SED's, such problems usually don't exist.
Re:On a related note, Toshiba's SED making progres (Score:5, Interesting)
Previously mentioned power consumption is a little more interesting. When Sony made JumboTron stadium displays, they found that the CRT mechanism is an astonishingly efficient way of turning electricity into colored light with the characteristics they wanted. JumboTrons are huge arrays of tens- to hundreds-of-thousands of little CRTs. What makes normal CRTs such power hogs is that the electrons have to be accelerated agressively to fly the distance from the back of the tube to the phosphors, and 2/3 of the electrons hit the shadow mask, and so that energy is wasted.
Similarly, in LCD screens, in the best case 2/3 of the light of the backlight is wasted by the color filters (all the green and blue light is always blocked by the red pixels, for example) and typically at least 5/6th of the light is wasted (if the pixels are half-on).
For the SED, every electron generated lights up a bit of phosphor, and only those pixels that need to be lit have any power usage at all.
Again, it'll be great if they can actually be produced in quantity. Apparently they are planning to ink-jet print the electron-emitter array, so that shouldn't be too expensive. I'm sure that the first few years of production will be as expensive as plasma screens, but hopefully that price will come down. We'll see.

1080p chips will need to interpolate 720p broadcasts, and they will look crappy. You have three standards that matter in HDTV (there are more, but only three are actively being used):
EDTV, 480p: Most stuff produced pre-HDTV get shown as this, and the TV networks are trying to convince us this is "HDTV" so they can create multiple chennels on each slice of the spectrum. Bad networks!
720p: Most sports are broadcast like this, because the progressive image handles rapid movements far better. Sports are what is really driving HDTV's, because nobody has step up to offer HDTV porn, and do you really want them to?
1080i: Those gorgeous landscapes PBS etc broadcast are likely done in this, since there is about 1/3 more vertical data. But fast movement gets motion blur as the odd lines out show the old location, and the new lines show the new locale. Icky.
So let me know when they introduce a 2160p panel. Light three pixels for 720p, two for 1080i, (or better yet, line double the resolution up). The tech exists, and the panels aren't that big a part of the expense...

That's the problem. Native resolution on the Cinema HD is 1200 veritical pixels, 120 too many. So you can either sacrafice 10% of the screen and run it natively, or you can interpolate those 1080 pixels onto those 1200, so about half the native pixels are actually showing two "blended" pixels. The quality of the resulting image can vary considerably. You would think the result might be better with 720p, where every
