My frustration aside, I have to say the future for mobile handsets looks amazing. 3D XGA screens? Who would have thought...

But again, you'd think phones would get thinner and smaller, but with these new demanding hardware, more power and processing speed will be needed, and so it's unlikely phone's would be as light and thin as one would think by then.]]>Aug 6th 2008 1:29PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/Aug 6th 2008 1:15PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/Aug 6th 2008 1:18PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/

If you want to have even more images available (so you can look at the object from different angles, say) then the loss factor gets even worse. A 1024x768 image divided up to provide eight different viewing angles is only 128x96.]]>Aug 6th 2008 1:17PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/Aug 6th 2008 1:21PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/
The lense wouldn't divide the resolution of the image. That would cause the dimensions to change, as you stated to a tiny 128x96.]]>Aug 6th 2008 1:30PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/
So, a 1024x768 image split up eight ways would be 128x768, with each image horizontally compressed into the 128 pixel width.

The real question is: will they have a corresponding lenticular lens on top of the phone's camera, to allow you to do 3D video chat? That would be neat to try out.]]>Aug 6th 2008 1:44PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/Aug 6th 2008 1:54PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/

Higher resolutions just improve dithering, diagonals, and fine lines after that.

I don't know if it is as true for moving pictures, though. It is surprising how bad individual still frames of a DVD can look, for instance. You just don't have time to spot the flaws. Though, certainly, a good HDTV looks better than a good SD set, and 35mm and IMAX look better yet.]]>Aug 6th 2008 4:14PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/
Before someone brings it up: the only reason why many color printers need higher resolution is that those use dithering (or error diffusion) to mix millions of colors out of 3-5-7 different ink colors. Color displays work differently so they don't need higher resolution to create true colors.

I'm trying to figure out the point of your post. You feel no one should make a display that is higher than XGA resolution? I would hate to have to use an XGA PC monitor or TV.

Or are you really worried that companies are going to start releasing 500ppi TVs and monitors? If so who the f cares? I think it would be great to have a display that was so detailed my eyes were not able to discern every bit.. it would kinda be like real life!]]>Aug 6th 2008 3:34PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/
You're used to the common, but not near so correct, usage of resolution for the image size in pixels, which naturally should be larger with larger sizes, keeping more or less constant linear resolution if the viewing distance is constant, and more or less constant angular resolution in any case.]]>Aug 6th 2008 4:41PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/
You are wrong. The word "resolution" is often used incorrectly. For simplicity many companies started using "resolution" for describing the size of pixel array but it's completely inaccurate.
There is no such thing as VGA or XGA resolution. Those are image sizes and they don't tell anything about resolution. Resolution means pixel density, with the unit "points per inch" or ppi(dpi). For a typical computer monitor the resolution is around 100 ppi, about third-fourth of the human eye resolution in the typical viewing distance.

A quote from wikipedia:

"Note that the use of the word resolution here is misleading. The term "display resolution" is usually used to mean pixel dimensions (e.g., 1280×1024), which does not tell you anything about the resolution of the display on which the image is actually formed (which would typically be given in pixels per inch (digital) or number of lines measured horizontally, per picture height (analog))."]]>Aug 6th 2008 4:44PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/
Instead of answering my question you are acting like you are correcting me. You aren't correcting anything.. read the damn questions. I was trying to figure out how you were using the term.

My question is still unanswered. Are you seriously worried that companies are going to start releasing 500 ppi TVs? Why would that be a bad thing. Why wouldnt you want a display that made you eyes the limiting factor like in real life? I'm sorry to burst your bubble, but that will be how it is one day.. theres no reason to stop increasing resolution. Higher resolution can lead to a lot of great things besides tiny text that must be read with a magnifying glass... oh hey look this article is an example of one of those things.]]>Aug 7th 2008 9:43AMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/
Well I think I answered my own question. You seem to think pixels are too valuable to waste. This was your comment on the article about Japan's plans to improve HDTV. I see why you were low ranked there.
Don't worry man I promise there is no shortage of pixels in the world. Just because you apparently have terrible vision does not mean the world should stop making higher resolution displays.

Oh yeah.. and I also ran into numerous posts made by yourself using the term resolution incorrectly. You actually used it in the same way everyone in the world uses it, and no one was a big enough twat to correct you because that is the way the word is commonly used.

This article is actually the first time you have ever used the word resolution correctly so I feel I was completely justified in asking for clarification on how you were using the word.]]>Aug 7th 2008 11:16AMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/Aug 6th 2008 1:27PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/Aug 6th 2008 1:50PMhttp://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/http://www.engadget.com/2008/08/06/seiko-epsons-500ppi-3d-display-for-phones-how-dense-is-dense-e/
