Nomad05 writes "Samsung announced this week it has developed the world's first three-inch VGA LCD panel that "directly meets industry interface standards for digital still cameras." What this means is that future LCD screens on digital cameras will allow multimedia to be viewed at a resolution of 640x480. Presently, a majority of camera LCDs only display multimedia at a resolution of 320x240 — significantly lower in quality than Samsung's new LCD. In layman's terms, expect significantly brighter, more detailed LCD displays, which will enable you to review your photography more thoroughly after you take an exposure. This innovation will make it easier to spot blurry images and ensure your photo is framed properly. "

      I'm sure it won't have a positive effect, but it may not have as much of a negative effect as you'd think. Back when I was doing Palm OS programming, I kept track of the trends in Palm hardware, and most of their machines are battery-powered devices using 320x480 displays (so half this resolution). Hardware review sites would do various battery life tests on new units, including various combinations of display off and on, CPU running and idle (and therefore halted and using very little power), backlight off and on, etc. And what I remember noticing is that the LCD really doesn't take up nearly as much power as you'd think. It's mostly the other parts of the device that use up the real power.

      Also, I'm not really sure that a higher-res display will use much more power at all. Most of the power used is from the backlight, if I recall correctly, and that is going to be proportional mainly to the total area -- it shouldn't matter much how many pixels there are in that are. As for brightness increases, if this means a brighter backlight, then it might use more power (assuming all other things are equal), but with an LCD, there are two ways to increase brightness: one is to brighten up the backlight, and the other is to reduce the amount of light that the LCD blocks. The latter means you can get a brighter screen with the same backlight. If they do that, then it wouldn't necessarily increase power usage at all.

  • If you go to Intel and ask for one unit of their latest embedded processor, they'll sell you a technology demonstrator kit. It's cost more per unit than if you were buying 200,000 units, but you can actually get one. The same pretty much goes for RAM chips or USB chips or whatever. Not for displays though. For some reason you can only buy displays by the thousands, unless you buy one from someone who has already bought them by the thousands. Most of the time it is cheaper to buy some consumer electronics device which has the component you're interested in it and pull it apart.

      • The entire LCD display industry currently operates at a per unit loss, so they have to make it up in volume.

        Your statement makes absolutely no sense. The only thing selling at a per unit loss in high volumes will get you is high losses. $0 x 1,000,000 units is still $0. Worse yet, -$10 x 1,000,000 units is -$10,000,000. You tend not to stay in business with that kind of model.

          That would be false.

          You make the false assumption that cost per unit is constant regardless of volume. That is rarely the case in real life, and especially not so in the case of high-tech manufacturing.

          There are a bunch of very large fixed costs - the highlights include R&D and the construction of the manufacturing plant. If the marginal manufacturing cost is less than the selling price, then the higher your volumes, the more units there are to amortize those fixed costs. Thus larger volumes mean smaller losses.

          Presuming your marginal cost is relatively constant, then at some point larger volumes will mean a cross from red to black, or in other words profitability. But even if that point is unattainable (say for instance it is larger than the total market) you still lose less money by selling higher volumes.

    • I'm going to go ahead and assume that TFA mentions something about a backlight. But since brightness=quality in most people's eyes (compared to contrast, which actually gives a more accurate picture), they might as well just make stuff up since they have no idea what to really look for when buying stuff.

    That's assuming you don't suffer from hyperopia.

    What I'm looking forward to is a few years from now, when my 15.4" laptop screen will have the same DPI as this new panel. Of course it will take a couple gigs of dedicated VRAM, but the SVG based www of the future sure will look crisp on it!

  • VGA at 3" -> a pixel every .095mm, "a human can resolve distances of about 0.93 millimeters at a distance of one meter" wikipedia, 1000 / .93 * .095 = 102mm

    So any farther than 10cm (3.9") from the display and you cant see the full detail of the image displayed. I guess it will work.
    • it's 10 (+.2) cm (4.0"), you rounded down twice. The image will be better between 4" and 8", 1/2 vga = .190 mm using your numbers. That's about the distance where you look at a camera picture.
    • We can't see motion faster than 30fps, either, yet anyone will tell you that 60fps looks much smoother. Likewise, refresh rates higher than 60Hz on a CRT shouldn't matter, but in reality 75Hz is better.
  • What do we need that for on Slashdot?
  • Getting 640x480 on something that is only 2-3 inches wide is fantastic. If you think about it, that's about 200 dpi, which is pretty darned sharp. (Your average 17" screen is running 1024x768.)

    I'd love to see PDAs/Cellphones take advantage of higher resolution displays, too. Though I don't know how that would affect power consumption or processing power.
    • Even more stunning is the screen on the Sony UX180 [tomshardware.co.uk]. That's running a 4.5" diagonal display (about 4" x 2.25") at a resolution of 1024 x 600, which is absolutely phenomenal.

      Add to that it's Xbrite and touchscreen capabilities and I reckon it's pretty much about as good as you can get at the moment - sort of coming in at around 260 dpi. When you run Cleartype on it in Windows, the anti-aliasing is virtually invisible, it just looks like paper.

      Regarding the power consumption - AFAIK, the UX180 screen is LED
  • Sharp and Toshiba both make PDA-sized VGA screens. Maybe NEC, too. I think the Toshiba is a 640x480 screen, while the Sharp is a 480x640 screen.

    Look up the Toshiba e805 PDA. Or the Dell Axim x51v (which can be had cheaply). Both feature a 3.8" VGA screen.

    So all that's been accomplished is the screen is an inch smaller.

    I've had QVGA screens that were 1.6" in size, so they had the same DPI as this screen...

    TFA says digital cameras, and then talks about 30Hz. Display syncing is not an issue for still applications- only for video.

    What this really means is that you will be able to get crystal clear standard definition screens on your camcorder.

    Of course its a bit late. A lot of the cameras now coming onto the market are shooting HDV and soon AVC HD- many in progressive formats and without the frame sync issues of SD video. So... they can include the older 60Hz LCD's and use frame doubling in the framebuffer. They can also use higher resolution small LCD's.

    Still this is a great technology, and being able to do this should help Samsung's institutional knowledge about LCD's in general. I hope to see some of these devices used in LCD field production monitors of varying sizes.

    This innovation will make it easier to spot blurry images and ensure your photo is framed properly.

    Say what? The images that are rendered onto the tiny screen of a camera are sized down with aliasing algorithms. Although the resizing will happen at 640x480 instead, this will have little impact since we do no longer take memorable pictures at this resolution. Memory is so cheap now and I'm sure we can get four gigs under a hundred bucks soon, too. So, either way, the picture is always going to be scaled down and viewed in proper resolution once you've zoomed in a few times.

    Also, the higher resolution won't do anything at all for those of you who want to spot blurred pictures with more ease. Even if it's definitely a higher DPI, you end up watching at 3 inches which is very small, so blurred objects that appear not so sharp will appear sharp on this tiny display, simply because the blurred area will appear so small on a small screen, it won't even be noticable. Once again, zooming in is the only solution.

    Either way, I'm sure someone will come up with an algorithm that detects blurred images automatically. It may not be 100 percent proof, but that's still a lot better.

    I'm obviously trolling here, however. More DPI is always nice and I bet we can go to 1000 DPI before we stop bothering that much about it, but the arguments used in this article made no sense to me.

    • Say what? The images that are rendered onto the tiny screen of a camera are sized down with aliasing algorithms.

      Not necessarily. My Canon S80 has a manual zoom function. In that mode, the center of the screen is a 1:1 blowup of the CCD image so you can focus better.

      Either way, I'm sure someone will come up with an algorithm that detects blurred images automatically. It may not be 100 percent proof, but that's still a lot better.
