Curved TVs Nothing But a Gimmick 261

Lucas123 (935744) writes "Currently, the hottest trend from TV manufacturers is to offer curved panels, but analysts say it's nothing more than a ploy to pander to consumers who want the latest, coolest-looking tech in their home. In the end, the TVs don't offer better picture quality. In fact, they offer a degraded view to anyone sitting off center. Samsung and LG claim that the curve provides a cinema-like experience by offering a more balanced and uniform view so that the edges of the set don't appear further away than the middle. Paul Gray, director of European TV Research for DisplaySearch, said those claims are nothing by pseudo-science. "Curved screens are a gimmick, much along the same lines as 3D TVs are," said Paul O'Donovan, Gartner's principal analyst for consumer electronics research."

      Curved TV's aren't better? I can't believe it!

      The odd bit is at the end of TFS where they say that curved TVs are a gimmick like 3D TVs. There is a big difference, 3D TVs actually give an appearance of 3D when viewing 3D content, (all the brain-and-eye confusing tricks and deception notwithstanding). Every reasonably normal sighted person can see the 3D effect, most just don't think its worth the price (or the headaches).

      Curved TVs on the other hand provide a picture that is indistinguishable from normal flat screens, EVEN when you see them side by side in the store.

        • I don't own a curved TV, nor am I interested in defending the concept, but one thing I do notice with flat TVs is that even matte displays are prone to reflecting at least some fixed outside light source to the viewer. I can't help but wonder if a curved screen would reduce this.

          I have a window that reflects off of a matte display and is annoyingly visible on the screen during the day. The only way to get rid of it is to either put a heavy blanket over it or to turn the tv in a very uncomfortable angle.

            If you have a glossy flat TV, then there will be one particular angle where light hitting will reflect right at you and annoy the crap out of you. For a curved TV, there the light will reflect off different parts of the screen for a wider range of angles, thus annoying you even more.

          • A curved TV will make it far worse. Instead of a single reflection on the flat plane, the reflections will follow the curve.

        • Only if use use a Monster cable between your cable box and your TV.

          I wouldn't say that. Like 3D, nobody is really going to get any value for their money out of a curved TV. Like 3D, it's a desperate grasping for some way to get people to buy a new TV before the old one dies.

        I've spent some time watching a Samsung curved TV, and it certainly is distinguishable from a flat screen. The picture does seem to have a bit more depth. Less accurate, but interesting and enjoyable. I'd liken it to a hifi system. You can have one that is extremely realistic, or you can have one that has an "exciting" sound, and there is a place for both.

        Maybe it's like 4k. Some people can see it, some apparently can't. I'm sorry you couldn't.

      Then why are the screens in a real-life cinema flat?

      The answer, of course is that the camera (either film or digital) uses a flat sensor. Taking a picture with a flat sensor, and then displaying it on a curved screen, is just distorting the image. So the consumer thinks they're cool - but in reality they are watching an inferior picture.

        The picture is inferior, but that doesn't mean that the effect isn't enjoyable. In any case you got it wrong. The reason cinema screens are flat is so that everyone in the cinema can see them reasonably well. Curved screens only really work for one or two viewers.

    Samsung and LG want curved TVs to become all the rage because the only way to currently make them are using OLEDs and they own many of the patents for OLED screens. With that said, the Samsung OLED television got a glowing review from Consumer Reports - basically the only downside to the TV was the cost which is sure to come down in the future.
    • OLED doesn't really need curves to promote it though, the superior display quality and power efficiency will sell OLED once it is cheap and durable enough.
  • Don't get me wrong, I think they're a gimmick too...

    But why do movie theaters do it then?

    Isn't the *near* edge of the screen distorted for off-center viewers, and the far edge of the screen closer to perfect?

    Again, I think it's largely a gimmick, and wouldn't use it as a sole or major purchasing decision. For two otherwise equivalent (including price or at least a VERY small discrepancy) TVs, I might choose the curved one. Then again, I would be sitting in the sweet spot.

      Per the internets, the curving is done in movie theatres to help avoid the pincushion effect from the projector. Since we are talking about TVs and not projectors, the pincushion effect is irrelevant.

      Curved television displays aren't "largely" a gimmick-- they're just a gimmick.

    • Proportionally less curve in a movie screen as compared to the size of the room and the viewing angles. And yes, the screen is distorted for viewers seated towards the sides - but again. due to the lower proportional curvature, more of the screen remains clear (and the "sweet spot" in the center is wider).
    • I think the curve in movie screens mostly is to match the focal "plane" of the projector lens.

      The curved TVs look too curved to me. If they only had a slight bit of a curve, it might be interesting.

    First, I sit about 9 feet from the TV, not 16.5, so the curvature will be wrong anyway. Second, the price difference is already more than I am willing to pay for the whole TV.

    As TFA points out, only one person in the room would get an optimal view anyway.

    Finally, if the whole problem is just a bit of geometric distortion, couldn't it be mostly fixed by performing the opposite transform on the image before displaying? That would allow you to optimize for your actual viewing position and come up with a happy average for everyone in the room, or turn it off.

    I'm guessing they'll avoid my suggestion like the plague since it doesn't make the TV look expensive enough.

    • First, I sit about 9 feet from the TV, not 16.5, so the curvature will be wrong anyway.

      If you want to sit 9 feet away from a 4k display, you'll probably need a 120 inch screen. For 16.5 feet away, you'll want a 225 inch screen. By choosing an absurdly close viewing distance, you are depriving the set manufacturers of tens of thousands of dollars. Shame on you!

    This is actually a good idea for a computer monitor for one person. Any reasonable two monitor setup is going to be at some angle instead of completely flat anyway, it seems to me that a monitor with a large curve that you sit 1-3 feet from would be a pretty sweet idea (in particular make it so that you can fit multiple together). You might even be able to make a monitor that is adjustable (the screen is made of gel).

    Also I bet it is pretty much just as easy to built a curved one as a flat one, so there is no reason to expect a big price increase.

    A few months ago I started using a 4k panel as my primary monitor. Wonderful, I absolutely love it, with one* slight annoyance - At a distance of 2ish feet (rather than TV-viewing distances of 10+ feet), the edges have enough of an angle that the foreshortening becomes distractingly noticeable.

    If we could get a decently priced panel (c'mon, Big Names, Seiki has proven you can do it, quit trying to get $2500 for the same thing they list for $499!) with a slight curve to it, it would significantly improve the experience when used as a monitor. For TV, maybe not so much; but monitors, yes.

    Cinema screens are curved because cinema projectors use an anamorphic lens, and the curved screen is necessary to cancel that distortion out.

    TV screens are not being projected on with an anamorphic lens. There is equal spacing between each pixel on a TV. So making a TV screen curved simply ADDS the distortion that curved cinema screens are designed to prevent.

    This is the worst part though:

    The slight curvature also reduces visual geometric distortion. When you watch a perfectly flat TV screen, Soneira explained, the corners of the screen are farther away than the center so they appear smaller. "As a result, the eye doesn't see the screen as a perfect rectangle - it actually sees dual elongated trapezoids, which is keystone geometric distortion," Soneira wrote.

    WHAT? The screen is a rectangle, so our eye sees it as a rectangle, just as it would any other rectangular object! The visual cortex of our brain makes sure of that. How can someone who works with TVs not understand basic concepts of human vision?

    • And I have no idea where he gets "dual elongated trapezoids". I assume he's TRYING to describe what a rectangle would look like in a fisheye lens (which, again, is not how humans see things), but that shape would have curved edges. "dual trapezoids" is a very poor (and irrelevant) approximation.

Yes, our brains can "correct" the image and overall, it still looks like a rectangle; but at the same time, any content shown on the far sides of the panel look noticeably squished.

      • A road approaching the horizon is further away in the Z direction. A rectangular screen, seen from a direction perpendicular to its surface, is not. You may want to google "perspective projection". (Although of course our eyes are not a normal perspective projection, since our retinas are curved, and the image is flipped. Good thing we have that "visual cortex" thing I mentioned!)

      They eyes don't see it as a rectangle. But we don't with our eyes, we see with our brains.

      In a theater, the screen covers a much larger percentage of your field of vision, and the difference in distance to the center vs the edges can easily be several feet if the screen is flat. This is enough to be noticeable. In the living room, the difference will be millimeters, and you'd need a ruler to detect it.
