Sorry if this has already been asked but anyone know if the phone has 960x540 resolution after the parallax barrier? I'm not sure if the 960x540 is the actual screen resolution and with the parallax barrier it would half either the vertical or horizontal. So viewable screen res (since u cant exactly turn off the parallax barrier) would be either 480x540 or 960x275 per eye?
This could be a potential problem for web page viewing if the page can only be displayed at 480x540 or 960x275 depending on how they align the barrier.
I remember reading that the 3D is software controlled, so the parallax barrier (which is like a fine lcd gauze) can be switched on and off in software.
So in 3D on mode the resolution will be 480X540, and off will be the full 960x540.
I am willing to be corrected on this by somebody more knowledgable!
From my understanding the parallax barrier is a static physical filter.
Based on my experience with the 3ds, which also uses a parallax barrier at 800×240 effectively 400×240 per eye, when you turn off the 3d effect it is still displaying 2 images but both images are from the same view point. The parallax barrier is still working but since both eyes are seeing the same 400x240 image you do not get the 3d effect nor the full resolution of the screen.
Im just curious if out of 3d mode (for example 2d web browsing) the phone will be able to use the full 960x540 resolution while sending 2 480x540 images, one to each eye.
that does it, I'm officially confused about it now.
My assumption knowing nothing about the technology behind it is the resolution they quote is the effective resolution in 2d, if it was half that a lot of ppl would b pissed

I'm just taking a guess here but it's probably qHD total with each eye seeing half of the pixels. From what I've seen with the cross eyed 3d pictures your mind will automatically put them together so it should looks like a normal qHD screen.

I posed this same question over at Android Central a few days ago and was informed (presumably correctly) that the parallax barrier was dynamic, meaning 2D resolution was full qHD.
That's interesting, i thought about alternating the pixels (odd pixels to 1 eye and even to the other) but when i tired it with some text on the 3ds it looked like garbage. I didn't even think about alternating the frames.
oh well looks like we will just have to wait and see. I wonder how the 3d phones that are out now get around the parallax barrier in 2d
I think the evo 3D will most likely employ the kind of parallax barrier that can be turned off, meaning 2D will be completely normal qHD. If not, surely some of the people who've had hands on experience with it would have noticed it and mentioned it by now.
I was originally concerned about the halving of the horizontal pixels for 3D content, but since each eye sees different images, it's hard to really call it half resolution. Once your brain blends the two images together, hopefully it will be hard to notice any loss in horizontal resolution. Especially in dynamic content, like movies or animations.
Funny, when I look at a Nintendo 3DS, and switch off 3D, the resolution improves significantly. I'd say it goes to full 2D resolution, without combining images from different eyes. I closed my right eye and it didn't change anything. If you leave one eye closed and switch between 2D and 3D you can see the difference.

Parallax barrier stereo displays are always half res (horizontally) when the effect is on. So ScrapMaker's point that the resolution improves when switching off the 3D effect is correct. He is not saying that the resolution improves when using both eyes while the effect is on, which it does not.
The EVO 3D likely uses the same display technology as the Optimus 3D and Nintendo 3DS, where the parallax barrier is switched off in 2D mode (and therefore no loss of horizontal resolution). Basically the display is two LCD panels sandwiched together, the front panel being the normal RGB array, the back panel being a series of switchable vertical strips. When on, the parallax barrier directs the light so the each eye is limited to odd or even columns. The display is probably made by Sharp since they've owned the patents on this arrangement for some time now.
Is that parallax barrier visible at all when its turned off? Could it possibly affect sharpness/brightness/viewing angle of the screen?

It has been confirmed that the 3D effect works in both landscape and portrait, which I don't think either of those other two support. I suppose the parallax barrier could just switch orientation along with the content being displayed. But I thought the RGB array needed to be physically aligned the same direction as the parallax barrier lines. I'd love to see how they pulled that off.
peachpuff, I've had the same concerns over loss of fidelity in 2D due to the parallax barrier layer (even when off). Let's hope there is no noticeable degradation.

If it's like the 3DS, it doesn't affect the image because the parallax barrier is between the RGB panel and the backlight. Unlike the older style parallax barriers which act like a lenticular lens and were attached to the front of the LCD panel, those were permanently in 3D mode.
However, since the Sharp screens use directed light, rather than a mask, the viewing angles of the RGB elements would have to be fairly narrow in order to cull the opposite eye's frame. But I remember seeing an LCD panel with a dynamically variable viewing angle at CES a few years back, so maybe that technology comes into play here too. Otherwise the viewing angle would suffer in 2D mode. Anyhow, pure conjecture on my part, I'm looking forward to playing with the new EVO next month and hopefully a comprehensive teardown of all the new tech in there.

I used a 3ds yesterday and I have to say that I wasn't impressed. ANY slight shift in the screen cause the whole image to distort and breaking the 3d image my brain put together (if that makes any sense). And the 3D pictures looked like they were taken through a sock. I just hope the EVO 3d is better (I'm assuming it will be) because I had a headache for a good hour last night with that thing.

So I was wondering, if you took a 3D pic with the EVO 3D, and set that pic as your background, will it still be in 3D? I know they said the Sense won't be in 3D so does that mean the phones background pic won't be either,just gallery pics? I've tries searching for an answer but haven't found one, maybe someone here knows a little more??

From what I've read it should display 3D in portrait. So, I would think they'd be smart enough to put this feature in, but if they don't, some super smattering dev will.

If the phone can display 3D in portrait mode (which would be a feat, considering what I've read about how parallax barrier works), you still have the issue of capturing a portrait 3D image. Look at how the lenses are positioned on the back of the phone. They are designed to capture the same perspective of the scene as each of your eyes does. If the phones is in portrait orientation, the captured image would be equivalent to what you see with your head tilted 90 degrees. I don't think that would have the desired effect.
So you'd probably have to capture the image in landscape to get the proper 3D effect, and then either crop it or stretch it across multiple home screens rather than rotate it for portrait viewing. But then there's the issue of the effective resolution of 3D content, which based on my research would be half the horizontal resolution (every other horizontal pixel is seen by each eye). The UI elements would need to be rendered at 270x960, with every horizontal pixel replicated for each eye. That may not be very noticeable for true 3D or dynamic content, but I'm betting static content will definitely look less clear or sharp.
Yes, I've thought a lot about this.

yes, wallpaper are landscape but is portrait for home. Unless you use home in landscape mode.
My guess is that 3d pics will be saved with a different file extension that will not be available to be used as a wallpaper. No proof, just a hunch.

like in a 3D mkv video, left and right images are different files, i think 3D images will can be saved in a two different JPEG, and a live wallpaper will can join Left and Right images to make a 3D effect.
What would you like to see/think would be cool/only possible with the Evo 3D?
1. Dual focus images: Not sure how well this would work or how well the effect would even be perceived, but independently focus each camera when taking a 2D image (obviously requires someone to figure out how to use both cameras in 2D mode). Possibly result in a easy Tilt Shift photo.
2. 10mp image: Doubt this one is even possible really, but stitching an image from each camera together.

Assuming the boxes with the 1's in them are 5mp each, a 10mp box would be made by making lines enclosing the 2 other boxes - where the X's are.
With the 2x5mp cameras, you'd only have 1/2 the data necessary to create a 10mp picture.

I think it would be cool to invert the 3-d...
To take a picture of someone's head and "pop it inside out" so that their nose was the furthest point AWAY from you, rather than the closest.
I don't know if this would be as simple as swapping the two images or not - so the right displays on the left and the left displays on the right.
Nothing like playing with someone's mind by inverting the way they think the world is and showing it to them =D
Kalah, 5mp+5mp does indeed equal 10mp. Your way of thinking is a little skewed though. The pictures would come up essentially the same way the 3d pictures will be displayed on the phone normally (ignore the - signs, they are just for formatting since the site will delete extra spaces):
111111-222222- 121212121212

111111-222222- 121212121212
111111-222222- 121212121212
The picture doesn't show a larger area, just a higher pixel density. The problem is this will only work for distant photos as they are taken from just slightly different angles.

Alright... Kindof.
You can get 10mp across, but your vertical resolution wouldn't increase. You'd get some really wide pictures.
To double the size of a photo, you have to quadruple the pixels... Not double them.
I'd love to see some great high quality 3D Augmented Reality apps that incorporate 3D. I'm sure there would be good money interactive 3D AR. I know it's cheesy and all, but those little pet games are very popular (personally not a fan). One thing that I would find absolutely fantastic is an app that allows you to draw or create cool 3D shapes in AR. When you close out of the app, all your drawings save and when you open it again you can continue creating awesome stuff and building an alternate digital reality splattered with your creativity. And it would be vital to add in a feature so you can add friends so you can share your world with them.

Again, you don't really understand what "megapixels" means. It is already width x height in the picture. Example: 1000 px x 1000 px = 1,000,000 px or 1MP
If you double one dimension, you double the MP of a photo. I didn't say you made it "twice as big." Yes, I agree that when people say twice as big they usually mean twice the height and twice the width, which is really 4x as big.

You could also do something like this (ignore "-" sign):
11111 - 22222 - 1*1*1*1*1*
11111 - 22222 - *2*2*2*2*2
11111 + 22222 = 1*1*1*1*1* -where each "*" is a virtual pixel value, which is
11111 - 22222 - *2*2*2*2*2 -approximated by taking some sort of average
11111 - 22222 - 1*1*1*1*1* -between the neighboring (left right bottom)
---------------- *2*2*2*2*2 -top) actual pixel values.
---------------- 1*1*1*1*1*
---------------- *2*2*2*2*2
---------------- 1*1*1*1*1*
---------------- *2*2*2*2*2
simplest approximation would be * = (right + left +top + bottom)/4.
Using two camera for 2d shoot can have only benefit in focus and sharpness, because 80% of picture is same on bouth cameras
The 3D is nice and all, but the dual camera seems like it ought to have real potential:
1) HDR (High Dynamic Range) photos
2) Accurate? distance measuring
3) 3D model generation
4) Facial security for lock screen - 3D based, so can't be faked with a photo
5) "Corrected" 2D photos - use the differences between dual photos to filter out artifacts? Better low light photos / night vision?
6) Action shooting (alternate cameras for faster snap shotting?)
7) "Hand" lock screen? (take a 3D photo of your hand, to unlock your phone?)
Just throwing stuff out there I haven't a clue on how to actually create any of those, or even if they're possible.

my problem isnt just moving objects. it is anything that is NOT in a certain zone. If the object being filmed is too close or too distant, it doubles (instead of 3d).
With 3d photography, there ARE limitations on distance.
Remember, a camera doesn't work like your eyes which are able to do more than just focus.
A camera lens is FIXED in a specific position and when you change your focal points the fixed position may be either to wide or, when focusing at distance, too narrow.
Movie makers and professional photographers are aware of this and can work around it. Specialized 3d photography actually uses 2 cameras in sync with a rail that separates the cameras based on the focal point.
Here's a simplified example of the rail for home use:

For what the evo and point and shoot 3d cameras do, it's just fine as long as you know the limitations of distance (both macro and >40ft or so)

I appreciate this info... but... my evo 3d is struggling with objects even > 8 feet.
is anyone else experiencing the same issue? should i take it back?
To get as close as possible to a perfect 3D experience for human eyes, a 3D camera needs its two lenses to be the same distance apart as our eyes are. Notice the 3VO's "eyes" are only 1.375" apart. My eyes are closer to 3" apart center to center. What it means is that the near and far extents of the view taken will either be hard to align for focus or impossible and thus ignored by one of our eyes or the other. Far elements won't have as much 3D impact anyway, except in contrast to near elements in the same scene. You'll notice broad distant landscape scenes aren't the choice shots as 3D samples. Pick scenes with foreground (not too close) and background (and even middle ground) elements to shoot, and your shots will turn out fine. Make sure your camera is level though. If you don't then you won't see the 3D effect until you re-create that tilted relationship between your eyes and the viewscreen.
The depth in 3d is better on the LG optimis 3d. is the a way to change the evo 3d depth to there's or to a different setting

Please for all of us. Just go get the LG.

The same 3d content viewed on both phones is going to have the exact same depth and or popout. All the screen is doing on either phone is showing two pictures, one to each eye. The same 3d source is showing the same two pictures on either phone so the 3d effect has to be the same on both.
I think you may be thinking of the camera and not the screen. The evo's cameras are farther apart and would likely make the point where objects appear to pop off the screen farther away on pics taken with the evo. However, if you view pics taken with the optimus on the evo it will have the same depth as when viewed on the optimus.
And to answer your question, you can only adjust the 3d effect in games not in any pictures or video. The games use computer generated images so the effect can be adjusted. In order to adjust the effect in pics and video you would have to photoshop the images seen by each eye which is not something the phone can do on the fly.

Everything he said. Also, with some 3d software, you can adjust the depth of field.

Really? Or are you a fanboy of htc?
Because on youtube and on some topics here, people do say the optiumus 3d has more depth with the 3d effect.
Basicly you just said that the 3ds, evo3d and o3d all have desame depths, pop out effects...?
Maybe you can explain a bit more why people are saying the o3d has a better effect?
So if you watch a 3d movie, both the o3d, 3vo and 3ds will have desame effect, depths, pop outs ect?
You made me all confused

Yes, the depth will be the same if you watch the same files on any of these devices. The screen can't change the media, only the media itself can change.
Do some reattach on how 3d stuff works and you will see what I mean.

Yes absolutely the evo 3d, optimus 3d, and the 3ds will have the exact same 3d effect when viewing the same source file, such as avatar 3d or any other prerecorded media.
What people are referring to when they say the optimus has more depth or the evo has more popout is the pictures and video created by the phone. Since the evo's cameras are father apart the two phones will create a different 3d effect even when taking a picture in the exact same location with both phones. This difference is due to the 3d cameras and has absolutely nothing to do with the screen.
The 3d effect simply cannot have any difference in depth when viewing the same prerecorded media. Do a little more research into how 3d works and you will understand this better.
people. i just asked desame at the optimus 3d section and this is what ive got:
You are referring to the differences in the cameras, not the screens. Optimus photos viewed on the evo will have the same depth as when they are viewed on the optimus. All these phones are doing is showing two 2d pictures on the same screen at the same time while blocking the opposite eye from seeing the other pic. The same 3d source will have the same 3d effect on both phones. The same source has the same two pics when viewed on either screen and therefore cannot have a different 3d effect.
Now if we are talking about different sources then of course the 3d effect can be different.

Only true if one assumes that both handsets are using a parallax barrier of the same quality which works equally effective. This doesn't seem to be the case. (3d images on the O3D are supposed to be more crisp and the viewing angle is supposed to be wider as well)

seems the optimus 3d uses another parallax barrier, so it makes the screen much better in handling 3d.
The viewing angles may well be better on the optimus but when you're in the sweet spot on the evo there is absolutely no bleed over from the other image. This can be seen be winking each eye independently. Therefore the parallax barrier isn't effecting the amount of depth in the 3d when viewed properly.
The amount of depth is determined by the source not the screen. I suspect when people say the optimus has better 3d they're either not viewing the same source on both or they're referring to viewing angles which has nothing to do with the amount of depth in the 3d effect.

How can a less crisp screen be more crisp? Hhmm

Well thanks guys but at least with the 3ds it is possible to set the depth/power of the 3d effect. Maybe the optimus is set higher then the evo3d?
And will there be a fix so the evo3d takes better 3d photos?
It seems everyone agrees the optimus3d is better in that...
Most 3d games you can adjust it. When viewing a picture tap the picture select effects and adjust the 3d alignment to your hearts content. Make it appear far away or make it popout.

3d games are very different than pictures and video. They are computer generated and therefore the 3d effect can be easily adjusted on the fly. I have two 3d games on my evo and both can be adjusted over quite a large range from off to a lot of depth.
Pictures and video are a different animal. On the evo you can adjust the overlay of the pictures, which is just sliding one pic to the left and the other to the right. Now this does change the amount of depth but on most pictures there is only one point where the image looks correct without the other image bleeding over. This feature is there to compensate for the evo's, cameras being unable to swivel like your eyes. The cameras can't go crosseyed like your eyes can when viewing something close to your face. Some images will get the other image bleeding over and this feature allows you to compensate til there is none.
The problem is everyone here seems to think some super quality screen on one beats the other. Lol.
Ignorant.
People don't even see 3d the same. Certain types of 3d may effect someone more or less than another.
The LG simply assist with focussing on the 3d content.
Thus the content appears smoother more in depth. When really as you adjust. The LG cleary does too.
That would help eliminate the card board effect somewhat.
I'm not a doctor. Technologist is more fitting.
Sometimes an analytical view can assist in providing a better understanding of a competitors technical advantage.
This technology will be used by all manufacturers soon.
Then Apple will pull a patent out their ass or some bull**** rebrand it and call it the new hotness your grandma wish she lived long enough to have.
Apple will get its way and we will all get the iPhone.
Of course by 5 years time Apple would of purchased Android.
Rebranded it.
Send it out in pieces.
Call it the new hotness you wish you would of lived long enough to have.
Sorry some dork shiet. But you get it. I think.
