3dEvo: Pre-release miscellany

BlueScreen said:
Logical and probable? Conjecture? Forgot to add a crown of thorns and last meal there Judas. There is nothing probable, logical, or conjecture about Hulu or Netflix being announced at EVO 3D launch event. Since you put on the hat of Oracle and already new that Netflix and Hulu was going to be announced at EVO 3D launch event. Judas why don't you tell me when the launch date for EVO 3D is? You don't know do you Judas? I will be posting it May 2nd.
BSOD

something he said.
 
hmm. He seems to imply that on May 2, he's authorized to tell us something that will be announced at a later date. So, likely, nothing is going to be announced officially on May 2. And if there is, then BSOD's announcement won't be much of a "leak," no?

What doesn't make sense to me is this:

If I'm an employee of a company, and I'm in the know, and my company has set an announcement date, would I come on to some online forum to give out hints and announcements ahead of the official one?

Leaks happen all the time, but people need to understand that they happen anonymously because most leaks are in violation of non-disclosure policies that all employees are bound to. For sure it's grounds for dismissal, and at worst it invites a lawsuit.

So assuming BSOD really is VP of this and that, and he's also an engineer working on Rev this and that, and he's doing us all a big favor by leaking company secrets so we all have insider info and can act upon it by investing in HTC and Sprint, and we can brag to our friends that we know something about the Evo 3D that the rest of the world doesn't.... I disagree with his leaking of info on moral grounds. Someone who does this is clearly immoral, and I have less respect for him.

Throw in the fact that he was very publicly rebutted by EarlyMon over his technobabble about fabrication processes... And I know Early's real name and can verify that he does indeed work in the semiconductor industry... and with my own understandings, and ability to research and verify what Early wrote, BSOD has no credibility in my eyes anymore.

I apologize that this really isn't on topic, but I think it still adds value, if not to open some people's eyes about common sense and what kind of people exist in the world. I won't post about this anymore.

And we're moving on, or we're going to move into a thread lock.

Let's not discuss credibility further - that ended up with bad feelings and thread locks.

Cheers, thanks!

Hmmm...thought that a phone that could see through clothing would have deviated thread back on topic.

Any who, any buddy have an idea on how fast this thing can take a PICTURE with the dedicated shutter button?

I've been in many a situations where I have <5 seconds to snap a pic of something that will make my other phone contacts faces contort into weird things so this is an important aspect of a phone for me.
 
I want this phone to take videos and images by both cameras simultanously (but not in 3d so as to produce two sepparate images/videos). Then I can play the "can you spot the differences in picture 1 and picture 2 game.

I've seen a couple of videos showing the response time. The good news is that you can activate the phone's camera by pressing (or holding?) the dedicated shutter button. It then takes about 3 secs to be rdy for pic taking.

If it requires a hold, maybe it can bypass the lock screen. But that might be a security issue.
 
Does anyone believe that the E3D is supposed to get like 10 hours of battery life on heavy use?

I've been hearing rumors.

you will have to define "heavy use" before we can help speculate and guesses.

10 hrs of on and off use; lots of games and phone and internet... yes, i think it can.

straight up.. being on the whole time;
with movies, internet radio, games, tethering...
NO.. it will not last!

Well I only use my phone for about 6-7 hours a day, so anything better than that is good for me.

you talk on the phone for 6 to 7 hrs a day????
or what do you mean?

do you mean...
you have checked your battery usage..
and it says that your phone is awake for 6 to 7 hrs a day????
 
One thing I haven't really read mentioned is, obviously the phone has a great qHD resolution, but doesn't 3D processing require the splitting of pixels two-fold, technically making any 3D application used half the actual resolution?

At least according to our eyes. At least, this is how it works with the 3DS.

Not that I'm complaining because the resolution is already significantly better than a device like the 3DS and will still appear sharper.

I thought I read somewhere that the 3DS uses rectangular pixels so that the width of the pixel is half the length. So the total resolution is 800x240. But because half of the 800 is dedicated to a particular stereo channel, the effective resolution becomes 400x240.

And in 2D mode, two pixels (in the horizontal direction) are used to represent a single square pixel, so the effective resolution remains 400x240.

I have no idea if the above is true or just a bunch of speculation gone rampant. Not sure how the Evo works, but for sure, I'm going to pull out my old loupe and see if I can figure out how the pixels are configured :)
 
There is speculation that the qHD screen on the Evo might utilize a PenTile matrix. While I find this unlikely, it's worth some attention because PenTile sucks at rendering text, and IMO, it's a gimmick for simulating higher resolutions.

Current specs say that the screen will be manufactured by Sony's Super TFT LCD (S-LCD) technology. I don't think that precludes the possibility that PenTile is used. And PenTile is no longer limited to OLED screens. The Atrix is LCD but uses a PenTile RGBW matrix shown below:

rgbvrgbw-addressable-points.gif


Clearly that kind of configuration is going to suck at rendering a crisp horizontal or vertical line. It's worse than the RGBG configuration because all 4 pixel elements are zigzagging. In RGBG, at least the greens lined up vertically.

Anyone have any sources talking about pixel element arrangement in S-LCD?

I have no insight on whether pentile will be used or not but if it's using the same screen as the Tbolt, with a beefed resolution, I think we'll be fine. The Thunderbolt screen looks amazing, totally on par or even better than the iPhone 4's with a vastly increased screen size.
 
I doubt it would use Pentile, but if it did, it would probably be a deal breaker for me.

I've taken a close look at an Epic, which uses the pentile screen and I can tell the difference.

Pentile just looks bad and it's easier to notice pixels without looking too hard which I found annoying.
 
The appealing thing about this phone is the lovely UI. Sense still bores me, I don't care for 4g but the fact that the UI incorporates the 3D animations it does make me interested in the phone...just a tad

S-LCDs are used in a lot of TVs and phones, the Thunderbolt as noted previously, as well as a lot of Evos (past the first two LCD brands we had - Epson and the original, name escapes me, it's the one in my Evo) and there hasn't seemed to have been a pentile S-LCD yet.

Info on the S-LCD brand - S-LCD - Wikipedia, the free encyclopedia

All LCDs after the old calculator-types than people have seen have been TFT-LCDs - techs for it include over a half-dozen variants. CP/VA, PVA, MVA, IPS, AVS etc, etc. Outdated, but reasonable descriptions here - TFT LCD - Wikipedia, the free encyclopedia

Please note that discussions of the word "Super" associated with S-LCD came from news blogs like Android Central (oh, what an accurate source).

Super TFT-LCD is better known as IPS.

The S-LCD company produces PVA and S-PVA type panels, not IPS so far as I know. IPS tech would have to be licensed from Samsung competitors.

So - they'll either copy Motorola's scheme to get qHD or they'll simply increase pixel density. I guess only time will tell.

PS - I must say - pentile LCD is about the goofiest snake-oil I've heard of yet in LCDs, and I've heard of a lot.
 
Novatel is the other manufacturer of our evo screens. Mine's Nova as well.

Ok, I did look into S-LCD a bit but didn't find any details that could settle the matter. Granted, there's no reason for me to think that suddenly they'd adopt a PenTile matrix. But this is the speculation thread after all.

So according to the wiki article, S-LCD is a joint venture between Samsung and Sony. And Samsung holds the rights to PenTile technology.

I was under the impression that one of the main reasons Samsung used PenTile on their "OG" AMOLED screens was to reduce power consumption of the display. Because of the arrangement of subpixels, there was less overall light output, which means less power required to reproduce the same amount of colors. But this also meant a darker screen, which I personally verified on several Epics in various stores in my area.

Now we see evidence of PenTile on LCD tech (Atrix). So we know (actually we've always known) that a PenTile arrangement of subpixels is not dependent on an OLED-based display.

Thunderbolt is still WVGA. Atrix is qHD, and it's PenTile. Why? Was it a cheaper way to make a qHD resolution screen? Will the Evo 3D qHD screen take the same shortcut?

When Samsung announced they were ditching PenTile in the Galaxy S2, I figured they realized that PenTile was a flop, so hopefully, they have the sense not to introduce it again in their S-LCD displays.

Meanwhile, this article has good info on normalizing PenTile resolution to those with traditional 3-subpixel displays. Turns out, the qHD PenTile display is the equivalent of 640x360. Worse than the current Evo. It also explains why I thought the clarity on the Epic was so poor.

Yeah, I wasn't trying to slag the issue, just to clarify the S-LCD background and some LCD terms for people in general. Apologies if it came across differently, for sure.

And yep, I noted the same thing about the Samsung-pentile connection.

Originally, I understood it was because they needed to combat some sort of light-intensity imbalance that they had with the OLED chemical formulations (OLED is beeyootch for materials science). But - it might have started out that way and the power savings was a noted side-benefit. Dunno, honestly.

In any case - you're right in that control circuitry is control circuitry and once you have it for one, it's a hop, skip and jump to the other.

Can't believe that someone actually masked out a pentile matrix for LCDs tho - that would have to be just cheating on yield (less density=higher yield on displays, fewer errors as a function of overall processes) - or - as you say, for power. (OK, you've proved it, I'm using the dummy version of "can't believe" there.)

So - it might have a better return on investment, and therefore cheaper, if yield goes up - but the new layout had to cost up-front, a bit.

Still just surprised they would do this - existing normal RGB processes are scalable and yield is known and evidently supply has been successful.
