3D LCD Display

Powerdog writes "After 10 years of lab work, Sharp has developed a 3D LCD display that works without glasses. They expect to use the displays in games at first, and expand into PCs and TVs. Production begins in a few months and products using them should be shipping in early 2003. Naturally, I just bought two 2D LCD displays for my home office two weeks ago."

More than a mouthful

Double D's are more than enough on my LCD screen, thank you.

It does bring a whole new meaning to 'pop up ads', doesn't it.

3d displays cannot work

[PhysicsGenius]

Let me enlighten you on a few vision science basics.

Objects are perceived as the same distance away when light takes the same amount of time to traverse from each of the objects. Therefore you can imagine the world as a series of concentric spheres about your eyes, each sphere representing a "plane" of distance. In order to create the illusion of 3d on a 2d surface, it is required that the light traversal time be increased for those parts of the scene that are to be perceived as "deep". The problem is, while there are ways to make light go slower, the thickness of a sheet of paper (or even a computer monitor) isn't enough space in which to do it.

Therefore, until some fundamental hurdles are overcome, 3d computing is only a pipedream.

Are you really an idiot or just pretending to be one?

In other news, it has been discovered that rockets could not possibly operate in space because there would be nothing for them to push against.

I nominate "Physics Genius" for most egregious misnomer of the year.

Re:New business plan?

[Latent IT]

When you actually *make* something, it's not a mystery business plan. You say, wittily:


1. Create 3D LCD that works without glasses.
2. ???
3. Profit!!!


In this case, ??? can be expressed as:

"Sell 3D LCD for more than it cost to manufacture it."

Okay?

Good idea, but no dice.

Sharp has developed a 3D LCD display that works without glasses

I applaud Sharp's achievements in this exciting area of optical technology, but if the display only works without glasses, this eliminates a good percentage of computer users who, like myself, have to wear glasses.

Re:What would you use it for?

[avalys]

For displaying spinning renderings of the Death Star, silly!

Software

[Anonymous Coward]

Yes, you're right, but you forgot one significant detail: the software solution.

If you have a sufficiently efficient 3d card that has an incredibly low latency, you can emulate the long light traversal time by simply just sending the light from the deep objects *later*. This probably would require the logic to be integrated to the LCD screen itself because the signal latency in the vga cable from the sound card to the monitor in itself is too high. I'm unsure whether Sharp used this in their monitors, it'll be interesting to see when they give out more details.

Will this 3D display be ruggedized?

[TyZone]

I hope they're going to put some solid transparent material in front of the screen. I mean, dealing with fingerprints is already irritating, but all the LCD screens *I* have used would suffer significant damage if people repeatedly tried to reach *through* them.

You know, like, to grasp the rounded, perky ... uhhhh ...

Looking after you buy

[Anonymous Coward]

Naturally, I just bought two 2D LCD displays for my home office two weeks ago.

You are reading about monitors when you just bought two? Don't do that, you will only cause yourself heartache and grief.

When I make a major purchase, I research the hell out of it for a while, buy it, and then don't look at the market until I need to replace it. You will always find a better deal after you buy something, especially with computer hardware.

I'll actually be impressed when I can walk around the image and see different angles.

Mom, I can see up this Britney's skirt!

Henry Taylor Thomas, you get out of the TV projection area right this minute or you won't get to watch anymore MTV!

Great, something else to fight over.

[dohnut]

The screens can only be seen in 3-D from certain angles and distances, however, and a "sweet spot indicator" -- a small bar at the lower end of the screen -- appears solid black when the viewer is at an optimum position for 3-D.

Get out of the sweet spot runt!
MOOOOMMMMMM!

Already done

[PunchMonkey]

Sharp has developed a 3D LCD display that works without glasses.

I have a 3D LCD display at home that works great with or without glasses.

Now what would really be cool, is a 2D LCD display... I mean, sure they're already pretty thin.....

oh wait.... I'm supposed to read the article first, aren't I?

LCD display? Liquid Crystal Display display?

michael, you're going on The List, along with people who say "SAT Test" and "HIV Virus" and "GUI Interface" and "ATM Machine" and "NIC Card".

Check your math

2 x 2D = 4D
4D > 3D
