FYI - Can HTC tell whether your phone has an AMOLED or SLCD screen?
Short answer:
No.
Longer answer:
I bought my phone from Orange and thus the box comes Orange branded. Therefore, it doesn't say on the box whether than phone is AMOLED or SLCD (referred to as multitouch or something like that). I contacted Orange who haven't got a clue and just told me is AMOLED by reading their stock description. I contacted HTC UK and gave them the serial number of the phone. They said that at this present time there was no way for them to decipher whether I had an AMOLED or SLCD screen. There may be in the future but at the moment there is not.
The one bit of interesting information HTC could provide is that 90% of their stock is AMOLED and 10% is SLCD.
The reason I looked into this is because I can't really tell from the videos online what screen I have. There are some murmurings that all SLCD phones are bootloader 0.83 (what I have) but unfortunately not all 0.83 phones are SLCD.

Already read that. And I'd say it's actually pretty difficult to tell unless you have their exact screenshots.
And a magnifying glass!
The box for mine said "3.7-inch touch-sensitive screen", but it has the 0.75 HBOOT, so I really need to find a magnifying glass to check it.

If it's so hard to tell why bother?
It really is easy to tell
Go into a dark room and go into the settings menu (which has a black background colour). If the black is lit at all or slightly grey, you have SLCD. If it is totally black (and I really mean no light at all) you have AMOLED. I have both and it really is easy to tell them apart in by the contrast of the settings menus, not so easy otherwise.

that's not entirley correct. I have Amoled, and even in a dark room, it's not 'totally' black.

Because there are some rooting methods that require you to know whether you're on SLCD or AMOLED... Having said that there are workarounds but it would be nice to know which method before I start.
As for the dark room idea, I'll try it. Thanks.
I'm 99% sure mine has an AMOLED screen because the bootloader was 0.80 (before the 2.2 upgrade)
My box didn't mention AMOLED on the box (so it could have been either)
One thing I have noticed is that a block of white against a darker background appear to have a slight pinkish toothcomb on the left edge of the white block (eg the HTC clock widget that's usually on the main home screen.
I believe this is a sign of the pentile arrangement of pixels that you get in the Desire's AMOLED screen.

Without a magnifying glass though its difficult to be certain.
Do what I did:
http://forum.xda-developers.com/showpost.php?p=7257878&postcount=10
Take a picture of the phone with a macro zoom camera. The pentiles become easily distinguishable.
i had both amoled and slcd side by side and all i can say is that the difference is huge...
if open your browser and set text size to large and than browse to xda forums... with amoled you won't be able to read clearly without zooming in, but on slcd you will be able to read and see everything clearly..
other than that amoled is brighter and has more contrast but slcd has a lot more clearer picture, that is easily visible when you put two phones side by side
for me slcd is a lot better.

A work colleague has just received his Desire and one of the first things he did was compare it to mine. He has an SLCD screen and I have AMOLED. When placed side by side the difference is gobsmackingly obvious. On the SLCD text appears far smoother, although the colours do appear to be washed out.
I agree that the SLCD is better, but I will say that I am more than happy with my AMOLED screen.

Ok, I exaggerated a little. I actually have an AMOLED Legend and an SLCD Desire. Just for my own sanity I checked again and the Legend AMOLED screen does have totally 100% blacks, even in a completely dark environment. I assume an AMOLED Desire would be the same and hence as easily identifiable.
If you think about it, AMOLED will always produce complete blacks as each pixel is not even powered for black output. The light you report to see on an AMOLED screen can only be explained by reflection. If your screen emits light from 100% black areas then you have SLCD.

Well,one easy way is to put it next to your computers monitor while it shows a black image.The phone should be in the settings menu.If both seem about the same colour,you have an SLCD.If the monitor's picture seems grey while the phone's is pitch black,it's AMOLED.
I hope it helps those who don't have two devices to compare.
I have both the AMOLED and SLCD Desire. It's a clear difference. Mine has no bleeding around the edges. But It's clear to see the SLCD when the Call screen is on. The AMOLED is a lot blacker where as the SLCD is more gray than black.
The colours are also a lot more vibrant and alive on AMOLED, the SLCD looks washed out. The brightness is also higher on AMOLED.
You dont need magnifying glass. Droplet of water on screen will do.
I will be getting a Desire tomorrow or the next day and I don't know whether I'll get AMOLED or SLCD, so I want to know, are their quality worlds apart? Would it really make a difference to have either one of those? Is one better? How does both of them compare to iPhone 3GS's screen?
To the average person both are very very similar and you would not notice a difference without knowing there was two sorts of screens.
Chances are you won't get a choice of which to get, it just depends what is in stock.
Stat wise SLCD takes it on paper as being the best, but only marginally.
Honestly it really doesn't matter which you get, unless you compare two devices side by side you won't even know.
Because of the pentile matrix on the AMOLED, I would go with the S-LCD. The AMOLED is said to be over saturated in dark environments, and unable to read in the sun. I'd rather have balanced colors inside and readable screen outdoors. Also, the S-LCD have a real 800x480 resolution
Had both side by side for a while.
They are absolutely equal in bright sunlight. That said, people suspect that some amoled screens come out of the factory better than others.
Blacks, contrast and bright colours are absolutely better on the amoled
Bright whites and overall colour balance is probably a bit better on S-LCD
Pixel smoothness and small text readability is a bit better on S-LCD. That said, after you have amoled for a while you will realize that unless you keep your nose touching the screen, your vision will process the amoled screen the same way as the S-LCD. Takes some time though.
Battery usage: we made -accurate- -measured- tests, of the battery drain in milliamperes/milliwatts. They came out very close, the main difference is obviously that amoled display is optimized for displaying dark stuff. Overall I think you save a bit of battery with amoled, but anyway the results were that:
- on low-medium brightness (inside) amoled is almost always better. If you are displaying all white screen, they are closer
- on medium brightness it depends on what you are displaying (light vs dark) but there is not a lot of difference, although amoled tends to save a bit more
- on high brightness (outside) amoled almost invariably drains more than S-LCD, except when the screen is very dark. When displaying almost completely white screens at max brightness, amoled loses big time compared to S-LCD, but that is the only situation where this big difference happens.
One last noticeable difference is colour temperature, but that also varies from handset to handset. Amoled tends to be a bit on the warm side (at least on mine) and S-LCD on cool. The old 'problem' of the pinkish tint is gone with the froyo update, those few displays still affected by it could be counted as defective.
Oh and by the way, here almost invariably if the box doesn't say 'amoled' you are getting a S-LCD screen. I have to admit I was very surprised at first by the quality of S-LCD and mistaken it for a differently calibrated amoled for some minutes. Blacks are good, but not close to amoled, if you go into a dark room you should notice
My Desire is rooted and I've installed the AuraxTsense 8.3 Rom.
The Desire of my GF is'nt rooted.
We note a very big difference in the brilliance color: the white is a little bit yellow on my phone and in general, with the same settings, my phone is less brilliant.
Should this caused by the rom?
thank for all the suggestion
No, it's the difference between AMOLED and SLCD screens.
how can I check this? is there any "code" or whatever similar to recognise?
No code, as far as i know you have to do it visually.
Read this, I think the best way is to check how the pixels are aliened.
Another alternative: show a black image in fullscreen and darken the room. If you cant see your phone it's AMOLED as black = real black. if you can still see the screen and it's just very very dark you have SLCD.
A bit more technically speaking: on an SLCD screen the illumination comes from the backlight which is always on and "filtered" out. Unfortunately that can not be done completely - every TFT monitor has exactly the same problem. On an AMOLED screen black means no illumination hence no light.
dang. i dont know that desire got two type of screen. live in the hole so long.

the original version of the desire was shipped with the samsung amoled screen, after samsumg realised they had an awsome mobile screen they decided to "F" HTC in the "A" and tell them they couldnt produce the amount HTC wanted, so HTC went back to the Sony S-LCD screen
Or simply look at the box, if it says "3.7 inch AMOLED touch-sensitive screen", you got AMOLED, and if it says "3.7 inch touch-sensitive screen", you got a SLCD.

That's weird. My box says 3.7 inch touch-sensitive screen. However, when I compared it to the desire HD's slcd display, it shown all traits of AMOLED.(true black etc.) Wonder why is that so?

I don't have the incredible in my possession yet, but I heard they started using SLCD on the newer incredibles. Is there an easy way to tell which screen I have?
Go to Settings: About Phone and look for the hardware revision. 002 is AMOLED, 003 is SLCD.
Alternately, go into a dark room and load up an image with a lot of black in it. If it's completely pitch black in the black areas of the image, you've got AMOLED. If you can see some light bleeding through in those areas, it's SLCD.
Also, if you're getting a brand new phone then you have almost no chance of getting AMOLED at this point. The only real way to get AMOLED anymore is with refurbished or used phones.
I actually might prefer SLCD. I heard SLCD is closer to the top, thus things are clearer? I have a fascinate right now and I've gotten over the amoled hype...not a fan of oversaturation.
Hi.
Before anything. I don't have the original screen of this DESIRE.
I have the phone, I know it works because I can use Screencast with it and it makes sounds when I turn it on. It works 100%.
But since I don't have the original LCD I don't know If I have to replace it with an AMOLED LCD or with SLCD screen.
1-. These are not interchangeable, right?
2-. S/N is SH08GPL03124 P/N is 99HKZ041-88 , it's PB99200 T8181 EU Desire.
Best Regards.
For me it says on the box.

Have you got the box? If it's amoled it will be written on it. I doubt a slcd could fit an amoled and viceversa, so even if the screen has been replaced it will still be of the same kind it was shipped with. If you can't find the box then you can still tell wether it's amoled or not by simply looking at something black on the screen: if it's amoled black colour isn't displayed, so it's the same as when it's turned off. Otherwise if you have a slcd black will look less intense, more bright.

http://antondnagy.wordpress.com/2010/08/23/how-to-tell-if-your-htc-desire-has-slcd-or-amoled-screen/
This is how I test if my desire was amoled or SLCD. Firstly we must understand one of the amoled's feature which is "True black". This means the black color displayed on screen is extremely strong.
So, go to your room at night and switch off your lights. Click on settings page. You should see like as if the white texts are floating on air with a slight tinge of your hand's figure. Since the settings page, applications menu page is pure black, the blackness must be strong enough that it will blend in with pitch dark.
On SLCD however, its a different story. If you try SLCD with the above scenario, you can see a back ground lighting effect. You cant miss it. And the black color is not as strong as AMOLED's. Colors on AMOLED are more vibrant and strong compared to SLCD. However on SLCD, pictures look sharper because pixels are more dense per dot.
There is a youtube video that demonstrates exactly what I explained above. Placing two HTC desire (one AMOLED , and one SLCD) side by side for comparison. Search in youtube for AMOLED vs SLCD OR place "d5daNfccSiA" on the youtube link replacing the text after ?v=
Thanks for the answers...
I don't have the box and I don't have the screen of the phone! It was cracked and the last user removed it and dropped it to the trash.
Is there any way to know with only the serial number or manofacture date?
Best Regards.
Yes there is, if your device is manufactured before 27 July 2010, and if you did not purchase it as 2nd hand but from a retail store.. it is most likely that your device is AMOLED.
Read HTC announcement : here. HTC stopped using AMOLED in their phones and was announced on 27th July 2010. However it will take some time for retail stores to finish their old AMOLED stocks before selling the newer SLCD stocks. You can estimate from here...
Hope this helps answer your question
Put a drop of water on the screen to magnify the pixels. If you can see pink "teeth" around the edges of the pixels then your display is AMOLED. These are what cause the AMOLED screens to have a pink-ish hue to them.

So I am coming from an LCD screen to the Nokia's Amoled screen and I am curious on Amoled screen is the white supposed to be a "rainbow" color? Like on my LCD screen White is well WHITE no other colors bleeding through. On this amoled screen I am see like a rainbow of colors behind the white like reds, blues, etc it's till white sort of but not as crystal white as the LCD.
Is this by design and something I should get used to? I thought Amoled was supposed to be better...

Whites on Amoled appear to be off-white. It's been this way with every Amoled device. I've never seen it to appear "rainbow" colored.
Amoled produces richer more saturated colors and outstanding black levels.
LCD and SLCD is a lot brighter than Amoled (hence the crystal white) but the black levels do not compare.
Before my 900, I was an SLCD fan. But Amoled with the clearblack looks like SLCD on steroids. Minus the lower white levels. Of course this is just my opinion.
So it's possibly just the ultra saturation bleeding through the "whites" that give it the "rainbow" effect. I don't know how else to to describe it. White is simply no white but like a multi spectrum white with other colors bleeding through.
Looking at mine right now the white looks pretty darn white.
The thing I have noticed is for instance when I bought a samsung focus I was torn between it and two HTC Devices... I forget the names. Both were SLCD. I just COULD NOT get past the washed out look of the HTC devices over the samsung.
The nokia is even richer in color than the samsung.

Agreed - I've had the Focus, HD7s, and now the Nokia 900 and the Nokia is so far my favorite. I feel I should point out that the 'Nokia Blue' theme is sharper than the default windows phone blue theme, making the other devices appear washed out when in fact it's the correct color.
But the ability to use the device outdoors was a huge factor in my selection, certainly.
I like all the colors in the amoled except white. White really looks washed out compared to LCD screens and this is the only disappointment I have with amoled screens.
the benefits of an amoled are color saturation, deep rich blacks, and energy consumption on non-white backgrounds
SLCD create more "accurate" colors, that some see as washed out - generally are a bit brighter (lumens) and more white whites
the amoled produce off whites - if you compare the two, but you should not really notice it on an amoled unless you compare it to a true white
also, off angles can produce a slight blue hue to the whites
to each his own - I prefer the amoleds blacks (with the WP7 metro themes), to the washed out colors of an SLCD - but that does not mean you or someone else will too
could it be that your screen might be dirty?
i know on mine if i have some water or oil on the screen it will create a prism effect, which will rainbow the colors, especially with a white screen.
personally i haven't seen whites get a rainbow effect, but they are a little dim, which could be partly due to the screen tech (amoled) and could also be the hardware dimming them intentionally to save on battery (white is a battery killer on amoled screens)
but the inky blacks and pop of color from amoled makes me not really care, as the screen looks brilliant.
and the clearblack display on the nokia is great in the sun.
rainbow colors are only suppose appear on pentile displays. this phone has a true rgb screen so i dont see why

AMOLED does not inherently have dim whites. Samsung just programs a dimming condition into the firmware on some its AMOLED panels that make it dim the brightness based on the % of white pixels on the screen (as a sneaky way to improve battery). The Focus S has an extra setting that lets you disable this, but the L900 does not have that setting.

I see. Bummer
A dim AMOLED screen also helps prolong the panel life span a lot. AMOLED screens are extremely prone to burn in. Avoid extreme brightness and avoid leave screen on for extended period.
Just remember this: it is very easy to bump up a screen's brightness (brighter back light on LCD) but it is extremely difficult to produce true blackness on a screen. The strength of AMOLE is the true black because it has no back light. Each pixels emit light. Darker black = higher contrast. No LCD can ever match the black level of an AMOLED screen.

i wouldnt keep saying that lol, htcs IPS SLD 2 can almost match against the blacks of a super amoled and has better colors all around without having to be pentile. unless you were to compare side to side you would be completely happy with the blacks on the one x.
edit: http://www.engadget.com/2012/04/05/htc-one-x-vs-one-s/ compare the blacks, barely a difference unless you were looking hard
i would go with the ips slcd 2 anyday considering no burn, great viewing angles, great battery life especially whites and cloes to as good battery life on blacks, visable outdoors, realistic looking colors/not over saturated, etc. its a balance between good blacks, and good whites. still wouldnt touch the one x though

I most definitely have. from samsungs first amoled screens the behold 2. and both gens of galaxy s.
and i take it you have used the one x? no? since its the only phone with the IPS SLCD "2". not talking about regular SLCD, i have the amaze and the blacks look like crap.
almost every reviewer that has had their hands on nearly every android handset has stated its the best screen they have seen. just my 2 cents.
LCD is growing, OLED is still failing with screen burn.
also, im no htc fanboy (anymore). i really want the lumia 900 actually
Any reviewer says SLCD2 is better or equal to AMOLED has no clue what they are talking about. For the most part, they equal high brightness to better display. Read those reviews carefully. They are probably the same idiots who prefer LCD TVs to Plasma TVs. They made no scientific measurements of the contrast ratio of the screens. So, basically they are simply talking out of their a**.
Yes, LCD has more accurate colors. But it can never have better or equal blacks. There is no way to make LCD panel to block backlight completely.

I guess almost every reviewer that has reviewed this phone talks out of their ass, technobuffalo, engadget, phonedog, telegraph? lol, nearly every review that i have read said that. people who love the galaxy s 2, and both aaron from phonedog and john from technobuffalo used the note as their daily and preferred the one x screen.
just because the blacks are one notch off doesnt mean it's not superior. considering it will have better battery life, much more accurate colors, sharper images (when compared to pentile especially), no screen burn (plasma tvs have that horribly, so id stick with my lcd tv). blacks arent the most important color on a phone lol, and i never said they are better or as good. they are pretty damn close though. especially for being a LCD. after seeing screen burn on plasma tvs and oled screen its hard to say id rather have one. people who want a little bit more black screens are okay with screen burn?
and horrible whites?
also, people who dont stay in a cave all day. the ones who go out side, ips is far superior lol considering you have grea viewing angles and its completely viewable outside.
compared to the galaxy nexus the blacks almost looks exactly the same.
i would rather have amoled screen on wp7, but on android i would probably rather have the sld2

look at this photo: http://i43.tinypic.com/2wn7jfd.jpg
you can barely tell a difference between the menu dots and the bezel. opposed to other lcds. it could be comparable to amoled defintely.
outside photo with low brightness: http://i44.tinypic.com/ipqgzs.jpg
still compeltely visible
overal its all about personal preference, but im sure saying that the new screen is comparable and would even be hard to choose from even over super amoled. i was about to ditch LCD honestly (my amaze has horrible blacks) before seeing this screen. too bad its not in other phones.
Screen quality better be left to those know how to compare, e.g. those who review hdtv for a living. lmao the stuff you quoted above.
Remember, contrast ratio = brigest / darkest. The slight difference in black level significantly changes the contrast ratio. Not so much on brightness.
Yes, there are magic coatings on LCD screens that make them appear dark then actually is. The problem is such coating could cause black crush or false contour. Of course those phone reviewer didn't test those important aspect of PQ of a panel, did they?

Not really something to even think about. OLED hasnt been seen on a mobile devices over WVGA resolution WITHOUT pentile, we all know pentile sucks. colors, sharpness, etc. we have HD screens with IPS completely sharp, great colors, etc. just my 2 cents
http://i-cdn.phonearena.com/images/articles/48137-image/100-Crop-Red.jpg <- pentile
you dont need to review tvs to know if a mobile screen is good or not. these people have had their hands on nearly every android/wp7/blackberry/wm6 handset. pretty sure they have some say, especially for engadget always hating on every company besides apple then says the one x has the best screen they have seen lol.
both AMOLED/SAMOLED, and IPS SLCD have 16m colors. except the IPS has better viewing angles, no screen bleed, able to see the screen outside, whites to look blue, etc. you dont need to be a reviewer to know which is better.
unless your like everything on your phone to be black, and nothing but black then i dont see the point of saying oled is better just because the blacks are a notch better..
on different OS i would prefer different types of screens. LCD would be crap on wp7 i think unless you used whites a lot. we have yet to see IPS SLCD on wp7 i dont ever think we will. on android though i and other people like having high resolution, good looking colors, etc. cant have that with amoled unless you like pentile. wvga doesnt cut it with android anymore
take a look at the nokia 701, has lcd with clearblack and the blacks look great one it.
FYI, iPhone 4/4s has IPS screen and yet it looks hazey and has the lowest contrast ratio among almost all smartphone screens. IPS maybe better than other LCD screens. But it is still LCD screen. It is physically not possible to completely block the backlite. Otherwise, we don't need local dimming technology on high end LCD TVs anymore.
