New Substrate Tech Creates System LCDs

timothy posted more than 11 years ago | from the just-toss-the-cpu-in-there-too dept.

Science 129

smartalix writes "Sharp Microelectronics has recently developed a new LCD substrate technology called Continuous-Grain Silicon (CG-Silicon), that enables device integration on a scale previously impossible. The technology enables the creation of System LCDs that integrate all driver and operation circuitry -- including digital logic, LCD driver, power supply, I/O interfaces, and signal-processing circuitry -- onto the glass itself. Eventually even the device's CPU will be included on the substrate. A key SLCD feature is the ability to dynamically control the resolution and color depth, providing output in multiple-resolution modes while lowering overall power consumption. A 3.7-in. SLCD created with CG-Silicon had a power consumption of 14 mW for color VGA, 8 mW for color QVGA, and 2 mW for monochrome QVGA. The first commercially available product that incorporates the System LCD architecture is Sharp's Zaurus SL-C700 PDA, recently released in Japan."

Baloney Detection Kit

Warning signs that suggest deception. Based on the book by Carl Sagan "The Demon Haunted World". The following are suggested as tools for testing arguments and detecting fallacious or fraudulent arguments:

Wherever possible there must be independent confirmation of the facts.

Encourage substantive debate on the evidence by knowledgeable proponents of all points of view.

Arguments from authority carry little weight (in science there are no "authorities").

Spin more than one hypothesis - don't simply run with the first idea that caught your fancy.

Try not to get overly attached to a hypothesis just because it's yours.

Quantify, wherever possible.

If there is a chain of argument every link in the chain must work.

Occam's razor - if there are two hypothesis that explain the data equally well choose the simpler.

Ask whether the hypothesis can, at least in principle, be falsified (shown to be false by some unambiguous test). In other words, it is testable? Can others duplicate the experiment and get the same result?

Additional issues are:

Conduct control experiments - especially "double blind" experiments where the person taking measurements is not aware of the test and control subjects.

Check for confounding factors - separate the variables.

Common fallacies of logic and rhetoric

Ad hominem - attacking the arguer and not the argument.

Argument from "authority".

Argument from adverse consequences (putting pressure on the decision maker by pointing out dire consequences of an "unfavorable" decision).

Appeal to ignorance (absence of evidence is not evidence of absence).

Special pleading (typically referring to god's will).

Begging the question (assuming an answer in the way the question is phrased).

Observational selection (counting the hits and forgetting the misses).

Statistics of small numbers (such as drawing conclusions from inadequate sample sizes).

Misunderstanding the nature of statistics (President Eisenhower expressing astonishment and alarm on discovering that fully half of all Americans have below average intelligence!)

Inconsistency (e.g. military expenditures based on worst case scenarios but scientific projections on environmental dangers thriftily ignored because they are not "proved").

Non sequitur - "it does not follow" - the logic falls down.

Post hoc, ergo propter hoc - "it happened after so it was caused by" - confusion of cause and effect.

Meaningless question ("what happens when an irresistible force meets an immovable object?).

Excluded middle - considering only the two extremes in a range of possibilities (making the "other side" look worse than it really is).

Short-term v. long-term - a subset of excluded middle ("why pursue fundamental science when we have so huge a budget deficit?").

Slippery slope - a subset of excluded middle - unwarranted extrapolation of the effects (give an inch and they will take a mile).

Confusion of correlation and causation.

Caricaturing (or stereotyping) a position to make it easier to attack.

Suppressed evidence or half-truths.

Weasel words - for example, use of euphemisms for war such as "police action" to get around limitations on Presidential powers. "An important art of politicians is to find new names for institutions which under old names have become odious to the public"

QVGA [handera.com]

QVGA is an emerging standard for Palm Powered devices. Traditionally, Palm Powered devices have featured 160 x 160 pixel screens. QVGA screens feature a resolution of 240 x 320 pixels. The QVGA standard was originally adopted for the HandEra 330. New products with built-in QVGA technology are anticipated within the coming year.

QVGA-aware applications include support for a high-resolution bitmaps, additional fonts, and a collapsible 'virtual' graffiti area. Optionally, they can also support landscape and portrait screen rotation.

Re:QVGA? (3, Informative)

SeanAhern (25764) | more than 11 years ago | (#5090118)

No. If the original poster is correct about QVGA being 240x320, then it's not the same.

The Clie with the graffiti area displayed is 320x320. If you collapse the graffiti area, the display is 320x480.

So the Clie would essentially be 2 QVGA displays stacked.

google says: 240x320 or 320x240

I am guessing that it stands for qurater vga, where vga is 640x480.

I think what is happening is that marketeers have decided that the average joe consumer doesn't lke to look at math problems when making a purchase so they have done away with numbers when talking about resolutions. These range from uxga, which i *think* refers to 1600x1200 down to qcif which i *think* is some god awful tiny resolution somewhere around 50x100. This leads to increadible amounts of confusion when purchasing products such as digital cameras, PDAs, laptops, and anything else using pixels. Personally I avoid any product labeled w/ letters instead of numbers ... I have a degree in math ... I LIKE NUMBERS!

Wait a minute, most math (after about the 6th grade) is done with letters of various types (you know, like x = y), and when you use up all the letters in your own alphabet, they start throwing in letters from other alphabets. If you stay with math long enough, they just make up symbols.

Re:QVGA? (1)

Alan Partridge (516639) | more than 11 years ago | (#5090669)

Ahh - CIF and QCIF. CIF is the Common Interchange Format, but it's not really Common at all because it defines different sizes for PAL and NTSC. PAL CIF is 352 x 288 @25fps (yep, Video CD) and NTSC is 352 x 240 @ 29.97fps. Weirdly, those same sizes are sometimes referred to as QCIF (Quarter CIF, although that could logically also mean 176 x 144 etc), implying that the 704 x 576 and 704 x 480 formats are the actual CIF sizes. These non-square pixel sizes are very much designed with MPEG1 and 2 in mind, and are still moderately well used today, despite Windows' inability to display non-square formats correctly now.

Also, what is right for the Japanese market is not always right over here. The way they use cell phones over there borders on some science-fiction movies, while companies are still trying to get online cell phone games to catch on over here.

It should be noted that the new Zaurus is already price competetive with similar high end PocketPCs (with only 1/4 the resolution) at around $700. While that's not exactly affordable to me, it compares pretty favorably with existing tech.

You need 6-7W for the backlight if you're using a CCFL (cold cathode flourescent lamp) to light the LCD, and then only for laptop screens. PDAs (and the new Gameboy Advance SP) use white LEDs, which run at low voltages and draw current on the order of milliamps, not amps.

Backward compatibility:
Most of the Zaurus SL-5500 programs that have been tested on the SL-C700 work. The SL-C700 will step down to 240x320 for older programs. However, no software has been thoroughly vetted and no guarantees can be made.

More info on power consumption (5, Informative)

hobbs (82453) | more than 11 years ago | (#5089715)

Wanting more info on this, I found: Sharp Slashes LCD Power Consumption [google.ca] which is from Feb 2001 and appears to be an announcement of the tech. I really wanted to know the relative power consumption (since my e740 pocketpc sucks power), and this articles says:
Compared to a conventional active-matrix display, which is refreshed between 60 and 70 times per second, the ULC (ultra-low-power consumption) technology only sends signals when the screen image is changed. This results in a
drop in power consumption to one-third conventional levels for moving images and one-thirtieth for still images

Re:More info on power consumption (2, Interesting)

sryx (34524) | more than 11 years ago | (#5090187)

With these screens ability to save power if less information changes maybe this will bring about a retro-revolution of cleaner simpler displays. I for one (being a computer user since MS DOS 5.0, yeah I know around here that's young) really enjoyed the simple low color depth interfaces of old graphical applications (Remember 3D Studio R3? No not 3D Studio MAX, but the original DOS version).
These applications pushed the available architecture as far and as fast as they could. Then suddenly CPU cycles became massively abundant (FPS freaks will disagree but come on, how many GHz or even MHz do you need to write a essay) and interfaces became cluttered, background images for dialogue boxes and shiny glowing graphical buttons for each individual task started popping up all over that place.
I know, I know, there where bad applications back then, but the landscape seemed more abundant with good applications. Well I should quit typing before I sound like a complete raving old fart ("back when I was a kid..." ect ect)... to late.

Actually, I'm pretty sure it can be made to. Even many conventional LCD displays can be made to do this since LCD's are basically mechanisms to block or let light through. Certain projectors work this way (with a light that shines through an LCD panel).

I remember some company making a laptop a few years ago (I don't remember the brand nor the model unfortunately) that doubled as a slide projector if you take the backplate off and put it on top of a conventional overhead projector.

So in principle, it's not impossible today to make your LCD window.

The problem was thet there is a hude varioation in speed between individual transistors. Making the worst case delay and clock distribution too painful to make the system usefull for anything.

They were at the Async confrence and they were very intrested in doing everything asynchronously. It makes sence as implementing the logic in asynchronous circuits solves both problems.

Now one way to deal with the problem is to display to goggles/glasses. But that certainly has limits. Especially when cool embeded applications like the above are being developed.

[dream]
It seems like the ideal would be something that looks and feels much like a piece of paper (but less rippable). Fold/roll it up and put it in your pocket. Then unfold it and have a nice big surface you can view, touch, write-on, etc.

Even more ideally, this tech would be embedded in such a way that you could mass-produce pieces of v-paper for cheap. So you'd use it like paper, but it would have full color display and internet connectivity.

actually this is the perfect solution for display to glasses/goggles. A transparent medium capable of displaying images and performing processing? You could have an entire computer built right on to a contact lens!

Dynamic display power management - wow (2, Interesting)

dara (119068) | more than 11 years ago | (#5089901)

The part that really interests me is the ability of the same screen to use less power depending on what you want to do. I own a monochrome PDA for battery reasons, but I'd love to be able to switch to color mode when displaying photos or color maps. I can imagine resolution changes too - QVGA (the Q IS confusing, here it means quarter, but QUXGA means Quad UXGA) might be fine for looking up an address, but for a 3" by 4" photo display, I'd want Quad XGA (320 dpi is not possible now, but someday). Then you could vary between (1/4, 1, 4) x VGA to save power.

Of course, a flexible OLED would be great if it uses no more power and is flexible to boot.

The New Zaurus (3, Informative)

yoz (3735) | more than 11 years ago | (#5089908)

One word: WANT.

Here's the press release and spec sheet [sharp-world.com] .

It's coming to the US... [linuxdevices.com] ... but Dynamism have done their own English port already. [dynamism.com] (Any stories/opinions of Dynamism?)

Keyboard doesn't look great [dynamism.com] (but at least it's better than the original tiny Zaurus one)

I've always wanted something tiny I could carry around that would give me decent QWERTY with a landscape screen capable of displaying VT100 readably (or, better, actual graphics) that could also connect to the net when I'm out and about. This looks like it (though expansion is limited to SD & CF - that's enough for WiFi and BlueTooth, though.)

Sharp Wizard OZ-770PC (2)

Wraithlyn (133796) | more than 11 years ago | (#5091016)

Check out the Sharp Wizard OZ-770PC. (Big picture [amazon.com] , specifications [sharp-usa.com] )

It's got a HUGE (for a handheld) keyboard, big enough to actually touch type at probably 50-75% normal speed, and a nice backlit landscape screen that can do proportional text and graphics (B&W only tho). A pair of AA's lasts 3-6 MONTHS in this thing.

It has 3MB of flash mem, and a genuine Z80 processor! You can code for this thing yourself in Basic, C, or even assembler, and there's lots of user written stuff to download. It's like having a complete 286-era system that fits in your shirt pocket.

Now, it's not Net enabled per se, however, it has a serial port, and there is terminal software written for it, so in theory you can connect it to a cell phone and access the Net through that.

It's several years old and discontinued, I lost mine recently and had to turn to E-Bay for a replacement. It's a really wonderful hacker's PDA though, and it has great community support. When I lost my original one, I did a bunch of searching for a modern PDA that has a similar design (large keyboard, landscape screen, clamshell case) and came up with nothing, especially for as low a price (it was $100 USD new)

Anonymous Bullard (62082) | more than 11 years ago | (#5091164)

Yummy indeed!

While I've so far managed to avoid PDAs these Zaurus guys are making it increasingly difficult to avoid the temptation.

At $700 the SL-C700 is really targeted for productivity applications, besides the usual organizer functions, but once their price drops to around $500 and they get the ability to stream broadcast quality video or TV (which I control remotely through a wireless IEEE 802.11 connection to my desktop doubling as DVR) and to (dis)play video CD/DVD discs through USB2 or Firewire-connected portable player I'm out of excuses.

Now that's the kind of remote Linux terminal I could do with.

I liked the part were a cereal box advertising display started spamming a commercial at Tom Cruise during a meal and he tosses it away. In minority rport, video displays were as cheap and ubiquitous a as paper. However, I think the inspiration was "electronic ink", a somewhat different technology.

swasson (639367) | more than 11 years ago | (#5089934)

What kind of cost increase are we looking at here? Most of the higher end (higher res) PDAs are fairly expensive to begin with. Now throw in this new "innovation" and you're looking at increasing the price of something that's already pricey.

Re:Cost? (2)

be-fan (61476) | more than 11 years ago | (#5090944)

The SL-C700 is about $500, which isn't all that bad for a product that isn't in the states yet, and one that uses such cool technology. Comparable to retail prices for the Toshiba PDAs, actually.

This is bad news... (3, Interesting)

webmaven (27463) | more than 11 years ago | (#5090075)

Crap. This means that we'll be dealing with displays that have completely integrated copy-protection mechanisms.

Even if current efforts such as Intel's HDCP [techweb.com] are flawed [securityfocus.com] , future versions of these technologies may not be amenable to cryptographic attacks, and hardware based attacks will be extremely difficult if the circuitry is embedded in the screen itself.

This falls perfectly in line with the Broadcast Protection Discussion Group's [eff.org] desire to mandate implementation of a broadcast flag that all devices must honor.

But it's also good news (2)

billstewart (78916) | more than 11 years ago | (#5090582)

... and for just about the same reason, which is that you can build communication systems with cryptographic protection that don't have hooks for wiretappers. It's really two sides of the same coin, with the big difference being who decides what features they want to include and who decides the content being communicated. If your one-piece-communicator has hooks in it that let the Department of Homeland Security listen in on your video calls, the same features can also let Joe Script-Kiddie copy the movies you're watching on it. And besides, you didn't really want to take the lame analog feed from your monitor or use a logic probe to extract the signals between your CPU and onboard video GPU or audio d/a converter anyway just to pirate movies as opposed to grabbing them digitally where you can transmit or compress them, so a device with integrated LCD and video display won't change that much.

athlon02 (201713) | more than 11 years ago | (#5091012)

how robust is the circuitry in the glass? I know on my iBook that on occasion when I try to move the screen back and forth to whatever position that I can see some slight discoloration around the area behind the screen where my fingers are pushing the screen into place. Will circuitry like this be able to handle that if it's put in a laptop? I would certainly like to think so, but am still curious about this.
