Thanks to xda-developer members we can now confirm SLCD and AMOLED device's screens can be swapped.
Currently the only known way to do this is to replace the whole motherboard.
Because it seems the connectors look the same but will not work when switched to another screen type.
Other ways are yet to be discovered.
I recommend you only to try swap if you really have to, otherwise stick to the one you currently own because the difference isn't that big.
Here I uploaded a pair of instruction videos of assembling and disassembling the device:

'HTC also claims new SLCD displays have “approximately five times better power management” than older LCD technology'.
AMOLED has better viewing angles than LCD & SLCD but LCD/SLCD shows better results in direct sunlight.
you can buy one, but I dont know If it would still work (connectors..)
heres one, http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260646947638&ssPageName=STRK:MEWAX:IT
hope this help! good Luck!
Quick question: I thought the SLCD's were the better screens between the two types?

who told you that lol amoled has much better colour definition and much better black definition, its also less power hungry
Amoled has awesome contrast and unbelievable dark blacks. In addition the colours are more saturated and look better in general.
HTC had to change to SLCD Panels because Samsung cant produce AMOLED screens fast enough (Samsung needs to produce them for Galaxy S too!).

Thanks hehe, I'll try it out if I feel like spending money on this experiment.
I'm also not sure if it has the same connectors. Have to research that.
Anyone here knows if it works or has tried it already?

Ah I see. Makes me glad I have the Amoled version.
lol, and I read on multiple reviews that SLCD was the better screen when it comes to power consumption

The AMOLED draws less power when displaying mixed-color and dark images... as soon as about 40% of the screen is white, traditional LCD (and I suppose SLCD even more) is superior in power consumption. In fact, when displaying a page that's mostly white (like black text on white background), AMOLED draws 2x-3x MORE power than LCD.
In addition, the pentile matrix on our Desire AMOLEDs makes text look like it's gone through a meat grinder (jagged edges, not sharp at all), and the colors are all neon-y. Not to mention the pink tint at low brightness...
The SLCD has far more realistic colors, is color-stable at basically all brightnesses and produces sharp text. Oh, and for my use (surfing the web, reading eBooks), it uses a LOT less power.
Check out the Froyo Battery Use thread over in the Desire General forum for more info, there's a ton of background information in there.
But the AMOLED screen stays perfect in heavy sunlight right?
Or do you think I should forget to replace it and just stay with the SLCD.
AMOLED is piss poor in direct sunlight!!

More like the other way around, although tbh the difference is slight.
Well I have done extra research on this. Seems, over all AMOLED is better. SLCD suffers from light bleeding from the edges.
I used my phone in direct sunlight today - wasn't perfect - however I could clearly read the screen and make out the text on it, etc.
If you can, I so go with AMOLED.
Edit: I have yet to notice the pink tint issue? And text looks clear and perfect to me.

The status LED bleeds through like crazy on both versions anyway... what's a little LCD backlight bleed?

Why go with AMOLED? Because you can barely read it in sunlight? Because backlight bleed trumps far lower power consumption, sharp text and realistic colors?

Compare it to screenshots (you can take them directly with the SDK) on your PC and you'll notice right away. All the greys are pink when the brightness is low...
Both have their pros and cons.
The SLCD is sharper, because of RGB Subpixels, has maybe better battery life with white backgrounds. The colors are more natural.
SLCD has a worse contrast (no true black). It also has worse viewing angles. The colors are more natural but less vibrant, and more vibrant colors just look better on a phone, so the colors are worse for me
AMOLED has a super contrast and real black. It has a better battery life with black backgrounds, which most mobile operating systems are optimized for in my opinion (or is the settings dialog white?). The colors are gorgeous. They are very vibrant, which means they don't represent the true color value, but who cares, it just looks better Who has an AMOLED screen? It's something new, unique, something special.
AMOLED is less sharp, because of the pentile cheating, no RGB subpixels.
Pink color: That's because of the pentile technique and is easy to fix with proper color profiles, which was done with the release of Android 2.2. So no visible pink at low brightness any longer.
Sunlight: In the images and videos none of them performed better. Both are readable in direct sunlight. None good.
HTC was forced to change to SLCD.
So both are almost equal. SLCD is a normal display type most phones have.
The only real disadvantage AMOLED has, is the pentile technique.
Else, it's my preferred display type, especially because I just wanted to have an AMOLED screen. The black and the colors are just impressing. I don't care if hte colors are natural or not, they have to look great, which AMOLED colors do. Especially photos look superb.
If I compare the Desire AMOLED display with the AFFS+ (similar to IPS, just better, it's the best you can get on a laptop) Display of my tablet PC, then I see a huge difference in the colors. Sure, the laptop display shows me the true colors, but they just don't look that nice. The black is not as black and the colors, like red, are not that vibrant. It looks somehow boring.
AMOLED was one important reason why I've bought the Desire.

I've always read that a black screen on a LCD display used the most power because every pixel is effectively on (blocking light) while white shown on a LCD uses less power because all the crystals are allowing light through... It would make sense, though, for AMOLED to use more power with white because every pixel is on.
But maybe this only applies to large format displays? (i'll look for sources)
Found quite a few sources just searching google for "LCD use less power with white" (including a scientific american article). But there's a current thread about the n900 where they talk about this specifically: http://talk.maemo.org/archive/index.php/t-59872.html
@Upspin
You're right, of course - both have their upsides. I just don't understand why you'd want your screen to show "unreal" colors. Might look better when you're just looking at the homescreen or icons, but what about watching video or looking at photos? I hate the way people (skin tones) look on my AMOLED Desire
As for battery life, there really is no contest when it comes to things like web browsing. Since most web sites use dark text on bright backgrounds, the power consumption with AMOLED displays goes through the roof... CyanogenMod has added color inversion to the browser to help, but that makes the scrolling in the browser choppy, and I like Dolphin HD

You just have to understand how a LC and an AMOLED Display work. Both work totally different.
On an AMOLED each pixel emits light on their own. Thus, dark pixels consume zero energy, red 1/3, green 1/3, blue 1/3 and white all of them combined. With the pentile technique it's not 3*1/3, but a bit different, not that important.
A LC, just as the name implies, consists of Liquid Crystals. The easiest structure is TN (Twisted Nematic). The principle is simple. You have a white background source, which consists of blue, red and green light. Together it appears white, easy. This background light is on, the whole time, regardless if you display black or white content on the display. But how do we get colors and black and white? Now you just have to place a (1) polarizer, (2) an array of Liquid Crystals, and a (3) second polarizer, which is rotated by 90 degree in relation to the first, in front of this light source.
To keep it easy we use a TN structure.
Without any voltage applied to our LC, the light from the background source passes the (1) first polarizer and gets linearly polarized. Then it passes the (2) LC, gets rotated by 90 degree by the twisted molecules and passes the second polarizer, and you see white light.
With voltage applied, the molecules in the LC get rotated, so they aren't twisted any longer. Now light passes the first polarizer and gets polarized again, passes the LC without getting rotated this time, thus gets blocked by the second polarizer and it appears black to you.
So finally:
A LCD has an always on background light. However, black needs more power because you have to apply a voltage to a liquid crystal, and a leakage current causes the power draw. White however needs less power, because you don't have to apply any voltage.
However, I think this effect gets really interesting if you have large displays or a high number of pixels.
Several magnitudes more power consuming is the background light.

Yup, true. I have to life with this drawback. Not that huge in my opinion, because battery life is fine for me. I recharge every day, regardless how full/empty my desire is, so really, I don't care that much if it consumes a bit more or less.
But nice tip with the color inversion mod, great for night browsing.

I need all the battery life I can get - almost never make it through a full day
I'll just stay with the SLCD if it doesn't make a really big difference anyway.
Recharging your phone every day? I always wait till the battery is drained almost completely then recharge till 100% full because that is supposed to be better for your battery.
Might just add a poll just to see ratings between what favors people the most hehe.
When i have googled i have found SLCD screens actually consume power blocking bright light...Hence bright wall papers ect are advised rather than dark wallpapers which are recommended for AMOLED.
Is That right???
And my question is i have an SLCD version so using apps like Screen Filter drains more battery??
More correctly, on LCD, the consumed power is independent of screen content. It doesn't matter whether your background is dark or light.
(Unless dynamic contrast is used, where (in case of only one (logical) backlight) the brightest area on the screen would define power consumption. But I never heard of the Nexus S doing that.)
For Screen Filter: The app itselft and applying the filter to every frame will use some power, but I don't think it will be much. But since you don't profit from it anyway, I would get rid of it.
thanks mate will practically test it without the screen filter....and let u know..
for black background SA will save power, however, for white and colorful background, SCLCD will save power.
So, it just so so, not that much different.
In the smartphone market the majority of displays are either AMOLED or LCD, but many people don't know that the wallpaper color you choose, yes, wallpaper, can actually make a difference to your smartphone battery life depending on the type of screen with which your device is equipped. Pure black wallpaper, or a dark-colored background in general, can actually save you a significant amount of battery life.
Display tech explained: LCD
LCD stands for Liquid Crystal Display and it's the same kind of technology you'll find in your televisions, monitors and so on. As the name suggests, Liquid Crystal Displays are actually crystals, and as such, they don't emit light of their own but rather transmit light from a light source behind them.
This means that even if you're looking at black on your smartphone or tablet screen, it is actually black lit up from behind. Therefore, LCDs don't really display "true" black
Display tech explained: AMOLED and OLED
Next, AMOLED. AMOLED stands for Active-Matrix Organic Light-Emitting Diode and it is also used for televisions screens but more notably, for smartphones. OLED displays are similar, but do not use an Active Matrix.
Samsung displays, for example, are usually AMOLED: the Galaxy S5, Galaxy Note 3 and Galaxy Note 4 all use an AMOLED display. The LG G Flex 2 uses a Plastic OLED display and the Google Nexus 6 also uses an AMOLED screen.
As the name implies, the screen is made up of organic material that actually produces light when a current is passed through it – electroluminescence. Because AMOLED displays can be lit up pixel by pixel like on the Moto X, black is "true" black because there is no back-lighting.
This also means AMOLED displays are easier on your battery because every pixel is not always lit up.
Battery life: AMOLED vs LCD
AMOLED
You can probably see where this is going: if you have an AMOLED display then you can actually save some battery life by using black wallpapers, or generally darker wallpapers and themes.
little experiment and figured out that you can save about 6% battery life/hour at 20% brightness by using a black wallpaper on an AMOLED display, and about 8%/hour at full brightness.
These results are based on an always-on screen, but the basic theory is sound even if the figures are not exactly set in stone. Another tester using a different method came up with a general 18% saving all day.
LCD
What about LCD battery saving wallpaper, I hear you ask? Sorry, LCDs rely on back-lighting, so there's nothing you can do to save battery there.
The only thing you can do is set your device settings to Battery Saver mode and try not to turn your screen on all the time. Keep your display brightness as low as possible and your screen timeout nice and short.
The good news is you can have the brightest colored wallpaper and themes imaginable and it won't make a difference to your battery. Just think about that when you look at the gloomy screens of AMOLED owners clinging to extended battery life (just don't stray too far from a charger while you gloat).
Other battery life tips for AMOLED screens
There are other things AMOLED owners can do to maximize their battery life too, like setting as many app themes to be as dark as possible.
If you can change the appearance of a bunch of apps you use frequently (or download a different app that does the same thing but that does allow appearance customization), you can save even more battery life.
After all, we don't spend all day on our home screens but more time in apps. You can also set your text and email preferences to be black background and white text, depending on your device and chosen apps.
The easiest way to figure it out for yourself is to fully charge your device as is and wait until it's almost totally dead and look at how much of your battery was used by the display. Just go into your Settings menu and look under Device Settings for Battery.
Make a note of the percentage your display has used up, then, while recharging your phone, switch to a black wallpaper and repeat the cycle to see the difference.
Great app :good:
Folks,
any experiences whether, on this device, a dark theme does save energy / battery power consumed by the display? I know dark themes do help on AMOLED displays but have no idea about the Moto G which apparently has an IPS panel built in...
TIA,
Kristian
nope, you already said it yourself. amoled turns off iindividual pixels(with their own backlight) giving almost perfect black levels and ofcourse battery saving.
ips panels only has one big backlight, that means even if the whole screen is dark you still see light shining through.
so you cant save power with ips panels
