Researchers have developed a LCD display that moves its liquid crystals for the best image quality

Virtually everyone has used an LCD display of some sort from a computer display, phone display or a portable gaming device to your HDTV. The problem inherent in the design of an LCD screen is viewing angles tend to be narrow for the best image quality.

Wayne Cheng and Chih-Nan Wu, a pair of Taiwanese researchers, have developed a LCD display that offers users a way to get better image quality regardless of the viewing angle.

The prototype display developed uses a small camera beside the LCD screen to track the users head and adjusts the liquid crystals inside the display for the clearest possible image.

The next stage in development of the new LCD display is to miniaturize the camera portion of the display by going to an infrared sensor that tracks the user by the position of their eyes. This would allow screens of this type to make it into smaller portable devices.

The one drawback to this technology is the system only functions for one user. This would not be viable for use on an HDTV where more than one person could be watching at once.

With more and more hospitals in the United States moving to digital X-rays, this sort of technology can benefit doctors and surgeons who are using LCD displays to make medical diagnoses.

you're saying that doctors simply glance at an xray from an obscure angle and make a diagnosis on that?

if i were the doctor i'd be sat in front of it so as not to get sued and fired for bad calls and such

i don't see how it's useful in this scenario..

Agreed, but in practice, the "Professor" has the screen and counts the money while the JUNIOR doctors look at the screen from an angle and do all the ward-work.

Don't forget surgeons in a surgery room. They would benefit from a screen that follow them so they can see a clearly from different angles.

last time I checked there was more then one person in a surgery room.

Last time I checked relaying information takes longer than reading it first-hand.

Uh...maybe you didn't get his post, but multiple people viewing means multiple angles, the "detector" camera would have trouble, wouldn't it, sunshine?

This would be great for when I lay down and watch movies.

LCD Window

I’ve long imagined you could use a display as an electronic window in an otherwise windowless room or area. For example in a basement or the cargo area of a van you could mount an LCD on the inside wall and a camera on the outside to provide an image. The one caveat would be that the viewer would see a static angle “out the window” unless there was a mechanism to change the camera angle as the viewers position changed.

I think this tech could make my magic window possible. Of course this is probably an answer to a question that no one but me asked.

That's cool, but it's just a static image without a camera or variable angles.

W/o parallax effects (the background shifting w.r.t. the window-frame as you traverse the room) it's weak on realism; that would be "difficult" to do for multiple viewers wandering the room.

The link's creators have an amusing feature: they've placed "virtual windows" where the fireplace's chimney should be obstructing the outdoors view in a classic house/fireplace. :)

Anyway, virtual windows go way back to at least the Starship Enterprise with its forward view-screen.

since this only works for one viewer, why not just rotate the entire display so the viewer always has a orthogonal view?

That's the engineering solution, these researchers are looking for a scientific one.

(Don't worry, I'm a scientist too.)

Assuming it could one day "lock" onto the logged-in user (retinal scan?) it would be a very cool for all visible light to only be seen by said user and no one else. Combine it with 3-D display technology... hmm, I just had a nerdgasm.

... better go wash up.

this seem slike a very crude way to address the viewing angle problem..

I agree. Its not a solution. Its a workaround to the problem.

...see this technology allow LCD to properly rescale to various resolutions...then again, I guess that'd require the crystals to be able to change size as well

Yeah... whatever

This can be great for very specific uses, but for normal use, and IMO, they will have to do better to get wider viewing angles because this is interesting, sounds nice and all but it is just a hack, maybe a pretty one, but a hack in the end.

Normal PC users won't care too much about the viewing angles, LCD TV users who watch TV in family won't be benefited by this (unless they put on many cameras and layered LCD panels so that each panel re accommodates its pixels to suit everyone's taste, though you'll always have a "maximum number of watchers" :D

This technology doesn't make a whole lot of sense. The primary person watching the display will most likely be directly in front of it. The extra viewing angles are really for the secondary viewers.

Interesting, but...

I don't know the details about LCDs' technology, but wouldn't it be easier to just make curved pixels or something like that to enhance the viewing angle? I mean, this camera thing sounds iffy at best. Surely there's a way to just make the viewing angle better all the time without moving parts.

my laptop already has 150 deg horizontal viewing angle, who is going to try to read at a 75 deg angle anyway?

there is absolutely no need for this technology. technology already exists to make viewing angle a non issue. sure the better screen costs more, but do you think this wouldn't? I cant believe people get paid for nonsense like this.

Interesting but...
