Sharp Develops Triple Directional Viewing LCD 220

morpheus83 writes "Sharp Corporation and Sharp Laboratories of Europe, Ltd. (SLE) have developed the Triple Directional Viewing LCD, a display that controls the viewing angle so that the display can show different images from the left, right, and center simultaneously. Using proprietary parallax barrier on a standard TFT LCD, the screen splits light in three directions — left, right, and center — and displays three separate images on the same screen at the same time. So connect three computers to the LCD and from the center you see Windows, Linux from the left and MacOS from the right."

      According to Sharp's PR [newlaunches.com], one possible use is as a dashboard display in your car:
      So while driving you can see the GPS navigation your kid at the backseat can enjoy Ace Combat on his PS2 while your wife in the passenger seat checks out tourist sites and restaurants all in full-screen view.

      That makes a certain amount of sense to me; with viewers essentially strapped in place, you can make sure everybody sees exactly the perspective they're supposed to. Also, in those circumstances, you aren't going to demand especially high resolution--as long as you can make out the information presented, you're OK. (Admittedly, the kid in the backseat playing on his PS2 might want better resolution, but that's his problem. In my day, if we wanted to play PS2, we had to actually get out of our car and walk inside.)

      They also mention the possibility of using it for displaying multiple ads in public, so that the ad you see varies depending on whether you are coming ("You're just a few feet away from Joe's Cafe!") or going ("Turn around! You just missed the best restaurant in town!").

        Depending on the relative price of the thing, you could also use it to have 3 monitors by placing 2 mirrors instead of actually buying 3 monitors. Assuming one of these could be cheaper than 3 normal monitors, you place it in front of you, then place an attacheable mirror at each side, and bang! 3-head fraging!! ;)

          And getting the system to render the left and right views mirror-imaged so they come out correctly in the attached mirrors is just a software problem.

          Actually, I'd be surprised if they didn't already sell privacy barriers for laptops that double as screen protectors when the laptop is closed, with a bonus panel for the top to cut down on glare from overhead lighting. The closest I've found is this laptop hood [dpreview.com] (scroll down) that folds like those collapsible windshield sunscreens.

          You know, if they made them in yellow, you'd look like you're about to be eaten by a Pac-Man.

        • well, for a laptop, cheaper would not be my key, the space savings.
          IE you have a 15" screen, a 15" mirror. It collapses down to a 15" form factor for transport, but you have a 30" (ok well 15" + 15*sin(45) = 26") widescreen monitor.
          (or just use a 17" mirror.)

          but your viewpoint would have to be absolultly fixed in relation to the computer for the mirrored screen to be affective.

      • There's no bleed. I've seen the 2 view versions, and they're fine. Thinking about the technology there's no reason to think there would be bleed (assuming you're sat in the correct place), since you've effectively got an LCD grill which is presumably capable of being just as dark as the LCD's used to make black normally. In fact, since they're not expected to be anything other than black or white, they might actually be better at it.

        • That's what I meant about Seconds-Per-Frame as opposed to Frames-Per-Second with GPS. If that refreshed once ever three seconds, it would probably go without notice. Hell, most of the OEM installs flip to a static screensaver after a 15s or so while driving, since even watching a moving map is of questionable safety, thus effectively dropping the necessary refresh on that panel to zero.

    I'm shocked no-one has mentioned this yet. It's useful for ads. As you walk past an LCD your angle changes, thus exposing you to three distinct moving pictures. People are drawn to moving pictures - we're psychologically hard-wired for it. I suspect we will see these in the entrance to stores, at eye-level, because as we walk past the store, we will be drawn to the changing images and moving patterns. It's 10 seconds of attention that wasn't there before.

    Imagine walking past a video-game store. As you walk past an LCD advertisement you see three different video games depending on your angle. Two of which may not be interesting. But that third, may. All done with one screen, saving money.

    The compactness of one video-screen emphasizes the efficiency. Instead of having to avert our eyes to see another image we focus on the single screen, thus avoiding a clutter of LCD's, which has the school-of-fish impact, where we can't focus on any of them.

    And, of course, everyone if fascinated with optical effects.
