I have the Samsung wave and it uses the same screen technology and I can tell that it does not have true blacks pixels are still lit, I can easily tell that its on and totally off there is a very faint trace amount of light produced..
[Galaxy S I9000 General] El Mono:
Since I first got this device and turned it on I have been impressed with the display. I am kind of partial to AMOLED diplays and am, thus, a bit biased. What surprised me was that it "appeared" sharper than the display on the Nexus One. Considering it is slightly larger and at the same resolution I just assumed that it wasn't using the PenTile arrangement - yet it appears that it does in fact use the same subpixel arrangement as the screen on the Nexus One. My point is... now I've forgotten my point. Basically that I am more than satisfied with this display.

As far as the black issue is concerned I have no idea. There must be some reason considering that was one of the supposed strengths of this technology (i.e. true blacks and lower power consumption).

El Mono
[Galaxy S I9000 General] scrizz:
wait so why would you display an image if you want to save battery?

really

How many of you have measured how much power is being used up when the display is displaying a true black image(measured with multimeter, or other measuring device)

How many of you have made sure that the glow is not caused by a residual charge in the display?

How many of you know how much time it takes for the "glow" to leave an OLED panel when power is not being applied?

just some food for thought

;)
[Galaxy S I9000 General] android53:
The thing is, amoled screens were advertised as having true blacks and having the pixels off when displaying black. this is clearly not the case
[Galaxy S I9000 General] Pika007:
It's not an issue with the technology. The screen doesn't have a back lighting panel, so i think it's more of a problem of what shade is default defined as "black" in the system, or something with any current running through the screen.
[Galaxy S I9000 General] android53:
Well considering the screen doesn't turn off when displaying a 100% black bitmap image, its safe to say that the say that the pixels NEVER turn themselves off during use when displaying black
[Galaxy S I9000 General] scrizz:
Could be the screen isn't calibrated properly, or they lied to us about the tech(wouldn't be the first time).
[Galaxy S I9000 General] ml78:
While its not "true black" it is defenently beyond what any backlit screentype can do regarding blacks.

Except perhaps for the retina display forged by god himself :-)

But I agree that if Samsung states True black then it should be able to do that.
[Galaxy S I9000 General] alovell83:
I was going to ask yesterday, but I was feeling lazy. Can the display, ever be true black without local dimming anyways? Without local dimming an LED is going to have these glows everyone talks about, and I think there might be some confusion on consumers parts, but that's just me trying to bring up a point that hasn't been mentioned yet. I'd guess this is less than 50% chance at being correct, but it's a thought nonetheless.
[Galaxy S I9000 General] ml78:
OLED screen... Each pixel is an Led so Yes it can go black. Explained a few posts back.
[Galaxy S I9000 General] robert_tlse:
Sorry, there is no "except" in this case, since god said "let there be light" and put a backlight in there :D
[Galaxy S I9000 General] Pika007:
While the color levels and balance on Apple's retina display are great, blacks are what you'd call avarage for an IPS panel, with the unique purple glow only ips panels tend to have.

Best balck levels on LCD displays are found on S-PVA panels.
[Galaxy S I9000 General] android53:
far too expensive for apple to use them though. god forbid they make less then £300 profit per phone
[Galaxy S I9000 General] coocood:
If is real true black,the contrast ratio would be infinite.

As samsung said the AMOLED ratio is 30000:1,there must have a litte light in black.
[Galaxy S I9000 General] Mithent:
It's just really odd though - it's not that there's some limitation of the technology which prevents true black being displayed on an AMOLED. Quite to the contrary - all it has to do is to not turn the pixels on.

Backlit displays can aspire towards blocking all the light output and producing something increasingly close to true black. An OLED already starts from the point of displaying true black, so it can only get worse! It's admittedly not a huge problem (except for NoLED) but it's strange that the contrast ratio would be worse than it could be.
[Galaxy S I9000 General] RyanZA:
I have no idea if this is correct:

Each pixel has to be sent a trickle of power to keep it active so that it can be instantly turned on when required. (This assumes there is some kind of delay for cold-booting a pixel)

Another slight possibility is that the pixel's are daisy chained together in some way that requires all pixels remain slightly charged for electricity to pass through the grid to turn other pixels on...

Another option is that the pixels work similar to a capacitor, and retain some charge even when turned off while they very slowly radiate out some light. In this case, they are not actually using any of your phone's battery.

Or.. it could be a software issue, where it is not sending the command for the pixel to turn off.

How would you test this? I have no idea!
[Galaxy S I9000 General] mike.sw:
I'm not a screen expert, but couldn't it be due to the reflections of light that omitted from screen elements and the protective layer of the screen?
[Galaxy S I9000 General] scrizz:
Lol let's read some AMOLED:

Technical explanation

An active-matrix OLED (AMOLED) display consists of OLED pixels that have been deposited or integrated onto a thin film transistor (TFT) array to form a matrix of pixels that generate light upon electrical activation, which functions as a series of switches to control the current flowing to each of the pixels.

Typically, this continuous current flow is controlled by at least two TFTs at each pixel, one to start and stop the charging of a storage capacitor and the second to provide a voltage source at the level needed to create a constant current to the pixel and eliminating need for the very high currents required for passive OLED matrix operation.

http://en.wikipedia.org/wiki/Active-matrix_OLED
[Galaxy S I9000 General] El Mono:
I've read some of the descriptions of OLED's and their attributes, and that black's are better because it requires no power when the pixel if off - it seems to make sense to me. But what if - and this will probably sound really dumb - in the "real" world slight illumination in the black region of an image "looks" aesthetically better, hence, the slight illumination of the pixels in question. Just a thought.

El Mono
[Galaxy S I9000 General] RyanZA:
From the wikipedia post, it sounds like each pixel has it's own capacitor :o which I guess bleeds off power even when it's turned off (there is no way to fully force discharge a capacitor afaik). So the slight light bleed you can see could be left over power in the capacitor?
[Galaxy S I9000 General] Prankey:
Seems you have a PhD in flat panel displays ;) Guess you did it before LED displays went to production... That was nice - "LCD/TFT/AMOLED/SAMOLED/etc" all at once, in the same league (guess we left plasma here)... have backlight :D . Sorry just having fun, could not control my laugh at the logic you were presenting - "a backlight to display a bright light" hahaha. Apologize, no offense though :)

:eek: Please think before writing...
[Galaxy S I9000 General] Prankey:
Ryan - that sounds true to me. Guess it will take some more time for LED technology to mature to be able to completely switch off pixels selectively and not "bleed" any leakage current (remember seeing such effect in other LED based applications like sound level meters of the past and the displays on elevators which have slight charge even when supposed to be completely off).
[Galaxy S I9000 General] android53:
If this were true we would see the same thing when putting the phone to sleep
[Galaxy S I9000 General] oswade:
Exactly what I was thinking.
[Galaxy S I9000 General] Schmich:
I guess at least the black we see, even if on, will use very little power unlike other colours.
[Galaxy S I9000 General] EarlZ:
Since the OP is basing his discussion on the NoLED application here is what I think of the subject matter.

When using the NoLED application to display a few red pixels, the author claims that he is only allocating power to the red pixels that are on and even turned off the drivers for the touch screen to avoid it from hogging too much power, now in theory that should ONLY consume power for those said number of pixels right? But what we are missing is that if even if the drivers for the touch screen is disabled for that time and only a couple of pixels are lit, the device it self IS already out of standby mode.. if anyone is able to make a home screen that shows only the same red pixels with NoLED and has the very same functions disable im pretty sure the power usage will be 1:1 with NoLED and the imitation home screen.
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] flinx:
Bought a T mobile HD2 (unlocked) second hand with energy rom installed.

Got it home & I find that the wifi & bluetooth are not working.

It picks up the network signal fine & the data connection is working fine.

But the wifi turns on & will not pick up anything.

The bluetooth it seems does not discover & is not discoverable.

I suspected it may be somthing to do with the rom so I loaded up a stock T mobile rom with the same results.

I have updated the radio with the same results.

The phone has Hspl loaded & I am wondering if I could do a complete cleanout of everything including Hspl & reload a completly vanilla stock Rom would that help.

I have fiddled with all the settings for both wifi & bluetooth & still no results.

At this point I need help!!!!
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] johnerz:
Run a task 29 then the stock rom of your choice, check the radio installed is compatable with the rom, hard reboot after completing the rom flash (its a good idea to do that first as well in case you don't need to run a 29 or flash)
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] Dryke:
I've the same problem ...I suppose.

I used a Touch Pro in the last two years and Energy ROMs since September 2009. I never had problems with Wi-Fi an Bluetooth.

Recently I bought a HD2 and tried Bloutooth and Wi-Fi only after 1 week.

So, both the Touch Pro and the HD2 got the same ROM (Energy ROM) flashed , each by its own version, but two days ago I discovered WiFi not working (DISCOVERED, because I never tried it before)

The problem seems an extremely poor signal seen on the on screen meter, only if I'm close to the router (1-2 meters!) I couldn't establish a real connection, because the HD2 loss the signal every 30-40 seconds.

Bothered about this I tried with Touch Pro: the result is the same!

So I concluded: "It's the ROM!". Strange (never had problems with Energy ROMs) but possible. I flashed the stock ROM on the HD2: the issue remains. So I thought about the RADIO, and I flashed the RADIO 2.12.50.02 (compatible with ROM). The issue is still here.

I used Task 29 before another flash, then I tried an Artemis ROM with RADIO 2.12.50.02... nothing changed. (note that I tried almost every different settings about Wi-Fi,from BsB tostandard enhance settings)

Last (related?) issue: when I try a hard reset, the progress bar starts to "move" but after 3-4 seconds (about a third of the bar) the bar disappears and I got the "Press VolUp button" message. Then the phone has the first boot... but I wonder if the HR is complete, because it seems yes.

Finally I came to this thread and... another doubt: what about BT?

I tried both the Touch Pro and the HD2 Bluetooths but they can't connect or recognize each other (every "Find" and "Visible" options activated)

I didn't try yet with Touch Pro (flash etc.) but I am very bothered and dubious about it.

Cooked ROM Energy Leo 1 Aug

WIFI & Bluetooth

Thus far I have run task 29

Reinstalled a stock T-mobile rom

But no luck wifi & bluetooth still not working properly.

Decided to go right back to the very beginning & uninstalled HSPL by loading the stock Rom from the SD card

Stock rom would not upload & i am getting the SPL 1.42.0000 Screen plus "Upgrade Rom code error please try again"

The question I have now is which is the proper stock Rom for this T mobile HD2 & how do I find that out?

You are not alone. I am experiencing the exact same problem and have yet to find an answer.

Task 29 didn't help and reflashing the radio the traditional way (even with the stock rom) doesn't seem to overwrite whatever is causing this problem.

Would uninstalling the hspl do anything? I am running out of ideas.

Also, when I use the quick search option, which should show me google results when I select to search on the web, it shows me telcel results.

I assume it's a telcel thing, maybe they did some changes to exclude some services.

How can I re-activate those services?

Do I need to install the respective ".apk"? If so, which .apk should I install? Because the services are there and running.

[Droid Incredible General] ejkeebler:
I have about 10-15 apps I always end up installing for every new rom. I was wondering if I could just use this method to create an update.zip so I could just load it from recovery after I load a rom. I tried and for the most part (swype excluded) the apps installed ok, but i noticed if I wanted to remove them I could not. I am guessing its because I put the apk in the system/app folder. can i put it in another folder to make it appear just as if it was installed from the market? I don't see any apps installed anywhere else to be honest?
[Droid Incredible General] themaker00:
I'm not to sure about the update script but I just use Titanium Backup to reinstall all my apps. Just download it from marketplace and run a app backup. So after I install a new Rom I just redownload titanium from the market place and restore all apps. Then I can uninstall an app or delete it from the backup. Not really sure if this helps you but trying to help others out.
[Droid Incredible General] TNS201:
If you did something like this you would lose all data associated with those apps such as settings, game saves, etc. Best thing is Titanium backup. Also if you installed the apps without going through the market, you wont get updates.
