bfries writes "Sharp Corp, Japan's largest maker of liquid crystal displays (LCDs), unveiled a screen Tuesday with microprocessor circuitry applied directly onto the glass, enabling it to function like a computer. It uses Sharp's continuous grain silicon (CGS) technology and should be used on some products in 2005."

Troll Tuesday in effect!!! (-1)

Trolling Stones (587878) | more than 11 years ago | (#4503443)

At subway, you get a sub prepared anyway you like, by the friendly, efficient staff. Choose from mouth-watering veggies, succulent meats and cheeses, and a variety of freshly-baked bread. Why not stop in today and pick up some subs for the whole family to enjoy. I suggest the Italian BMT, piled high with genoa salami, pepperoni, ham, and provolone cheese. Top it with lettuce, tomato, onion, and pickles, a few spritzes of italian dressing, and a dash of salt and you've got a meal fit for king. Subway: eat fresh!

g to the oatse
c to the izzex
fo shizzle my nizzle click here [jareddispatch.com] to dispatch Jared and his formerly overweight goons to crack down on Subway if they don't honor the $3.49 Troll Tuesday deal. Make sure you provide the store number and address. Mine is store number 5839. Don't believe me about the concept of the jared dispatch? Yahoo has an article about it here [yahoo.com]

Note: I've gotten a few comments that the link to Jared Dispatch doesn't work. I think the site got taken down because of abuse of the service. Although the site got taken down, I still highly reccomend Subway and their high quality subs. To show my appreciation, here is a link to Free Subway Coupons. I had to redirect it through Yahoo's site redirector, because my of the filter at work. Anyways, here is the link! [yahoo.com]

The Blimpies here where I work sells a hearty 6" sub with chips and a medium drink for $4.50. You can also get a small 4" sup with chips and a medium drink for only about $3.00.

I will inquire today if they have a Troll Tuesday discount, but it's hard to beat a $3.00 lunch.

Thank you for taking the time to mod this down.

How's it look. (5, Insightful)

FreeLinux (555387) | more than 11 years ago | (#4503485)

I'm curious about how these screens look. One of the issues with LCD is the screens appearance. They are often hard to view unless at a precise angle, if you wear glasses, especially polarized glasses, they are even harder to view. Touch screen films make them harder still to view and now they are embedding the actual circuitry in the display. What's the viewing like?

Heat dissipation (5, Interesting)

mortis_aeturnus (606421) | more than 11 years ago | (#4503493)

Glass is a very very poor heat conductor. Having anything running at a very low temperature on this would pale any laptop overheating horror stories. This would definately limit the power of the processor you can use. This would make a nice (and slower than 4.77mhz) palm top but nothing more.

Re:Heat dissipation (2, Interesting)

TheEnglishPatient (173496) | more than 11 years ago | (#4503543)

It depends upon your point of reference. Compared to a metal it may be a poor conductor but in a house the glass is one of the biggest causess of heat loss. Why do you think a winfdow feels cold in winter?

Oculus Habent (562837) | more than 11 years ago | (#4503632)

Brain fart... (5, Interesting)

Gruneun (261463) | more than 11 years ago | (#4503664)

What if the screen was made up of two pieces of glass, with water being passed between them? Water is obviously a proven way to transfer heat and it would be invisible to the user.

Re:Brain fart... (1, Informative)

mortis_aeturnus (606421) | more than 11 years ago | (#4503901)

The problem is the rate at which heat transfers in and out of glass. A heat source wrapped in glass will retain more heat because there is more of a resistance to heat flow.
Having a water medium will only serve to buffer the heat. Heat must escape somewhere. If you insulate water with more glass then the only effect of the water would be a longer time before the circuits overheat since the water only acts to store heat.
It is better to be able to siphon off heat directly from circuit elements, coating the glass with a better heat conductor than air, or reducing the impedence of the circuits.
By the way, having an Athlon in your system can very well boil the water (even with the applied pressure of the container).

Re:Brain fart... (4, Insightful)

Gruneun (261463) | more than 11 years ago | (#4504195)

Heat must escape somewhere.

My suggestion was meant to be more along the lines of the water-cooling (with a radiator) that is popular among the overclocking crowd, not just a static pool of water. A display like this could be mounted on a wall, with the pump and radiator in a separate location, connected by a hose.

Re:Picture of the product... (0)

Anonymous Coward | more than 11 years ago | (#4503794)

I think it says Z80 on caption of the foto. If it is indeed a Z80 it wont have too many transistors (20k - 100k max?, don't remember) and also a much bigger footprint than the original chip. these things will therefore not have the heat density of a modern processor, but you would also need a sliding door to fit in a P4. But for apps that don't need a P4 - like a truly portable display with just display decoding logic and 802.11, or a PDA application?

Seriously though - I can really see this sort of technology being used on phone booths (if it can be made cheep enough not to matter if its vandalised now n then) to make them display moving images while still being able to see through the glass to see that theres someone inside

It reminds me of a scene from The Time Machine where the hero blokey was talking to the hologram-type-librarian who was shown walking around "inside" pieces of glass...

Transparency (1, Interesting)

Anonymous Coward | more than 11 years ago | (#4503573)

i'm interested in how they get the microprocessor transparent. if you can't use the same space for c and lcd, then there's no reason for this combination

Re:Transparency (3, Insightful)

Oculus Habent (562837) | more than 11 years ago | (#4503847)

There's plenty of reason.

If Palm could make a PDA with one piece of glass instead of glass and PCB, it could save money.

Every LCD I've seen on a shelf or in a picture has a casing on it. If that space had extra glass with a microprocessor embedded - your LCD screen could be higher quality for less money.

If you want to go to the extreme of the clear hand-held computer, you will probably still have an area to hold it by and maybe even some buttons for using it, which will provide space for circuits.

Nice for HUDS (1)

Re:Nice for HUDS (2)

ari_j (90255) | more than 11 years ago | (#4503716)

Some HUD's don't project the image onto a surface, but actually project the image into your eye. I've seen a HUD built into eyeglasses frames, and it worked by creating a virtual screen of pixels on one retina that subtended some 30 degrees of the eye's field of view. Its screen was pretty cool, consisting of a row of fibers that vibrated back and forth at a known period and a timer that sent the right row of data to the fibers at the right time.

Re:Nice for HUDS (1)

MattCohn.com (555899) | more than 11 years ago | (#4503752)

Nope. Close, I'll give you that, but not there yet. I saw no mention of a Heads Up Display in the atricle, so I'm assuming they havn't worked on that little problem of focas. Imagine trying to read one of these things, and then trying to look through it... you can't do both at the same time. It's the eqivilent to holding your hand a foot from your face and trying to be able to read something on the wall and the writing on your hand at the same time WITHOUT re-focasing.

Digital Photos (5, Insightful)

Jezza (39441) | more than 11 years ago | (#4503599)

Well they're talking about ultra-high resolutions for things like photographs, and maps. Of course this is going to need huge storage and processing abiliy if they're going to reporduce photographic quality on anything larger than a really small display. I'm guessing that the display would probably be most useful if it could dynamically change resolution perhaps displaying several resolutions at once, to combine video (HDTV perhaps) a computer output at a "normal resolution" (90dpi or so) and a photo quality section (say 300dpi or better).

The abiliy to offload some of the processing on the display would be very helpful. I can see that being a very useful display. Still the idea of storage on the display sounds like Minority Report to me. Very cool.

Re:Digital Photos (0)

Anonymous Coward | more than 11 years ago | (#4503911)

Well, I want my computer output at at least 200dpi or so, personally. That way an A4 sheet will be readable when displayed life-size on my monitor.

Currently, I'm stuck at 120dpi, which means borderline bearable (akin to an 80s dot matrix with a brand-new ink ribbon) if I use a 1:1 zoom ratio [I'm careful to set up my DPI in X correctly, using the DisplayWidth and DisplayHeight options, so that applications written by the clueful know that there are so-and-so many pixels to the inch on my display]

1 GHz limit (5, Interesting)

Anonymous Coward | more than 11 years ago | (#4503609)

Reading up on the CGS link, it looks like the technology has a medium-imposed 1 GHz hard upper limit, since it's not really a single silicon crystal, but a set of crystals ("grains" in MatSci speak) in which some effort is made to blur the lines between the grains (hence "continuous"). My guess is some sort of annealing process. The grain boundaries become
a problem at 1 GHz.

Glass is a Liquid... (-1)

Anonymous Coward | more than 11 years ago | (#4503867)

Glass is a highly cooled liquid. Over time anything on it will warp as the glass changes shape - "melts" for want of a better word. This feature is often seen in very old windows where the glass at the bottom has thickened due to the "melting" process.

Re:Glass is a Liquid... (2, Interesting)

klocwerk (48514) | more than 11 years ago | (#4504069)

Actually this is a common fallacy.
Glass is a crystalline structure, and does not warp with age.
The old windows which people often point to as being thicker at the bottom, are that way because the glass itself was irregular, and was installed with the heavy part at the bottom as it is more stable that way.
Or so I've been informed by a professional glass-blower who should know such things...

Re:Glass is a Liquid...Maybe..maybe not (2, Interesting)

rdean400 (322321) | more than 11 years ago | (#4504123)

Look here for a discussion...Is glass liquid or solid? [ucr.edu]

The crux is that glass's structure is not clearly solid or clearly liquid. The explanation for the windows that have thicker bottoms than tops is that the old processes for making glass involved blowing a large bubble and then spinning it. The glass had non-uniform thickness, and was typically installed with the heavy end down.

IBM announced this new process [itworld.com] last year, which I understood would be a more cost effective way to make LCDs that the velvet rub. Is anyone using this process yet in manufacturing?
