How to know IF AMOLED OR SLCD?! - Desire Q&A, Help & Troubleshooting

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.

*SLCD or AMOLED*

As you all know, the new batch of Desire for Telus will come with SLCD.
androidpolice.com/2010/07/15/htc-desire-headed-to-canada-on-telus
I'm not from Canada so just wondering should I wait for SLCD to available worldwide or just grab the current AMOLED.
The main concern of mine is AMOLED with pinkish issue.
Anyone can tell me which is better ? Please to explain to me as I'm totally don't have any knowledge regarding SLCD & AMOLED.
Many thanks

I think it comes down to personal preference. I kind of like the AMOLED screen, and mine has a very soft neuance of a pinkish hue. But nothing that is annoying or anything. The SLCD is as you know the secondary preference of HTC, but it seems to be as good as the first choice..
I genuinely think if I wasn't a member of this forum and read pretty much everything about the desire, I wouldn't have noticed the pinkish tint to grey colours... That's just me, it really isn't bad and certainly not a deal breaker. For how often that colour even shows up, its not worth concerning yourself about. If you want AMOLED over an SLCD screen which I think is probably wiser seeing as it was HTC's first choice then get one now.. All I can say is the screens beautiful and full of colour, not having seen SLCD screens I can't say if it will be any different but unless its an improvement, then get an AMOLED one

Can't agree more. Haven't seen a SLCD live but I really like the shiny colors and this is enough reason for me to choose AMOLED over lcd I really don't care about the slight pink effect and anyway it's almost gone in 2.2.
I'm really happy with my desire
Regards
If you don't notice anything wrong with the screen on a Desire with amoled screen then don't bother with the canadian version.
Some people are just more geeky and uptight about these things.
Personally the oversaturated colors was the first thing I noticed when I saw the phone in a shop without having read about the issue on the internet.
Amoled: The colors is punchier and fuller, the blacks will be deeper.
This sounds really good and most people dont find the oled on the desire bad
at all. Because of the type of amoled they used on the desire the screen wont
seem as sharp as a hvga screen should be. If you want to see amoled screen
done right, check out the samsung omnia hd, just perfect.
Lcd: The colors arent as full but after having had a tp2 for 6 months i think it looks really good anyway. Any lcd screen with hvga resolution will appear alot sharper than the one on the desire. Also i found while the colors werent as deep as on a oled i found the color spectrum to appear wider than on desire. Dont know if thats true that just the way it appears to me and what I prefer.
The Slcd they will use on the canadian Desire will be a lcd with a
ips panel. ips panels arent normally used on cell phones but alot of
graphics artists use them on lcd monitors when doing photo work.
I think theyre supposed to show colors more accuratley than
tn or pva panels.
I know the viewing angles on them are really good,
like 160 degrees. The downside has been that they don't have quite as
fast response time as tn or pva panels but it isnt a big deal if youre
not a twitch fps player.
Also, I read that SLCD drains more power than AMOLED.

It is a contradiction. If colors are deeper then spectrum is wider. Amoled can display colors which LCD can't, and which doesn't even exists in any normal (sRGB) picture

I don't think that the colors are deeper and the color spectrum or color space is the same thing, maybe im wrong. I found the colors the desire screen showed were deeper, by deeper i mean more intense and fuller, as one should expect from a oled display. To me, the colorspace didnt seem as wide as on my tp2's lcd screen. That's my personal impression of it. It could be because of the pinkish hue wish also might add to the oversaturation of some colors. I found the color red specially to be oversaturated wich gave me the impression of the colorspace not to be so wide.
It's true that Amoled can show more colors than lcd, at least when oled
is done right.

You know what, im not sure that I can. I was pretty sure that ive read somewhere that S-lcd is the buzzword for Samsung's and Sony's joint venture for creating newer generation lcd displays with ips panels.
But now that I look for it im not so sure. I was certain i read an post on Engadget where they clearly stated that it was ips panel but I cant find that now.
There is one source vaugley explaining it here:
http://androidcommunity.com/htc-for...ft-lcd-from-amoled-due-to-shortages-20100625/
But it says:
"But, the big question is: what is Super TFT LCD? Well, you’ve actually heard of it before, because it has a nickname that’s come up recently in the news (after the announcement of a certain tablet). Super TFT LCD’s nickname is IPS. Which, yes, became “famous” thanks to Apple’s iPad tablet. It provides a wide viewing angle, and provides very clear images — even if the colors aren’t as “distinguished” when compared to an AMOLED display."
But the source of those news is:
http://www.oled-display.net/the-sma...tc-must-switch-the-display-from-amoled-to-lcd
Wich really doesnt say anything about being an ips panel
If the SLCD is even vaguely readable in direct sunlight, go for it. Because the AMOLED isn't, I don't care what people claim.
If it's an IPS panel, the I'd be very tempted to give 'SLCD' a try.
But whenever I pick up another phone since getting my Desire I notice the muddy, bleeding blacks that OLED eliminates.
It's official now. Wondering any review which is better..

That video kinda makes me feel good about having an AMOLED screen.
There's no screens named SLCD. S-LCD is the COMPANY that makes the screens wich will replace AMOLED-screens on HTC DESIRE. S-LCD is a joint venture between Samsung and Sony. According to wikipedi, S-LCD makes S-PVA panels (wich is even worse than IPS). The video showing the "new" screen on desire is clearly a S-PVA panel.

Patterned vertical alignment and super patterned vertical alignment (S-PVA) are alternative versions of MVA technology offered by Samsung's and Sony's joint venture S-LCD. Developed independently, they offer similar features to MVA, but with higher contrast ratios of up to 3000:1.....
PVA and S-PVA offer the best black depth of any LCD type along with wide viewing angles. S-PVA also offers fast response times using modern RTC technologies.
Source: Search Wikipedia for TFT LCD
I've had a new HTC Desire with S-LCD in my hand for a while, along with my old Amoled one.
It's surely a lot better than my old LCD (Touch HD).
What impressed me is the clarity of the display, the whites, the good contrast compared to old LCD and the fact that (I think) the phone is lighter.
Of course blacks and contrast are miles better on amoled.
But where it failed me, is better readability in direct sunlight. It's more or less the same as amoled, which is (for me) average. I can live with that, but I expected the S-LCD to compensate more for its shortcomings.
All in all, I feared worse, but I would take amoled any day.
according to my box, I have the amoled screen.
Must say I'm pleased with whatever it is !!

[Q] Amoled or Slcd screen

Hi
newby here been doing a lot of reading and just found out that there are two types of screen for the htc desire amoled & slcd.I'm waiting for a new desire to arrive in the next couple of days and was wondering if the new slcd screen was any better of worse than the amoled one.The reason for asking is that the desire is advertised as having an amoled screen and if its better then perhaps i should return it without opening the box as it would be not as descrided in the description of the phone.Can any tell me where to look on the box to see which type of sceen it is or is there no difference in the 2 screens worth bothering about.
Thanks in advance.

Nope, according to what has been reported in the news and what HTC is telling everyone, the Desire now has a better battery life thanks to the new SLCD screens.
AMOLED:
+ better contrast and black levels (makes for a better looking picture)
- can't see anything on the screen when used outside or when the sun is shining on the screen
- lower battery life
SLCD:
- a little lower contrast (but still looking great and much better than standard LCD).
+ can see the screen outside in sun light.
+ better battery life.
As far as I'm concerned, a phone I can't use outside due to a useless screen is of no use to me; so I choose the SLCD over the AMOLED. Of course S-AMOLED (as found on the Samsung Galaxy S) would be the best of both worlds (great contrast and you can use it outside).
SLCD is supposed to have at least 5 times better battery life than normal LCD, I don't think AMOLED can say that.
In reality the noticeable differences between the 2 screens will be little to none, however on paper SCLD does edge it.
Here's one comparison:
http://blog.gsmarena.com/htc-desire-with-s-lcd-screen-meets-one-with-amoled-they-go-head-to-head/
In short: The SLCD allows for better battery life and improved sunlight readability, while the AMOLED produces more vibrant colours.
Hi thanks for info mines arrived and it looks like its the s-lcd screen with whats on the box no mention of amoled ,but if the battery life is better then maybe that is the way to go if there's little to chose in the display side of the screen.Just got to diside wheather to open the box and get on with it or ship ai back as no as described ie no amoled screen.
Thanks in advance.

Welcome to the site. Didnt see your post as must have been updating mine when you made yours.
Will be trying the update tomorrow so its a case of "suck it and see"
Once done will re-post on sucess/failure.

Hi, I know this sounds stupid. But can you post a copy of the back of the box showing the difference, I have included a screen shot of my (I assume) Super LED box.
Until reading this forum I was about to try the Froyo update but have seen that there are different versions for the different screens, and without this forum would have tried the *Wrong Version*.
If this version info is wrong let me know as dont want to **** the phone up.

Hi! my first post here.
not to add more to the confusion but i have the same print in the box as yours and mine is still AMOLED display.
At first i thought it was SLCD and having nothing to compare it with, i bit the bullet and root using the one for AMOLED. no display blackout and all went well.
my guess is that the print in the box was to prepare for the roll out of the S-LCD even if there are still AMOLED display on stock.
of course you may have a real S-LCD so good luck.
I have the amoled screen and i can ALWAYS read my screen outside and very easily too.
Why do some people keep misinforming others that amoled screen is unreadable outside or in the sun ?!
Sent from my HTC Desire using XDA App
Hi!
I already test both Desire with Amoled and S-LCD and forget S-LCD...If you try Amoled first you will never go back trust me.
I love Amoled. You will never see the differences if you don't use it, and forget youtube comparative videos because you will not be able to detect the real differences...
For me Amoled it's much better and if you want to save baterry just work with sync settings...Why sync gmail contacts, facebook contacts, weather... every 1 hour?
Amoled or S-Amoled but only on galaxy I think for now...

If amoled is not specified in the specs it's SLCD.
about screen
the same situation, bought a phone in mediaworld and back on the box says "schermo sensibile al tocco da 3.7 polici" this means that the sensitive ekranb 3.7. diagonal. this also means that the screen SLCD?
then you can link tyknut where indicated as do root for SLCD screens?

I rang the freephone number for the UK and spoke to tech support.
They asked for the IMEI number and told me that I had the Amoled screen.
However my packaging "Didnt" have the amoled wording on it, and was told that the packaging had been changed before the screens had and some people had the "wrong" boxes.
So if you want to know what you have, just ring them and they will tell you.
Also if you got your phone before the middle of July it "Should be Amoled" again tech support (UK) words, cannot say for elsewhere.
Hope that clears things up. Lol..

Sometimes its so easy to get lost in the detail of making a problem difficult that the simple answers get overlooked.
I have always found HTC tech support (UK) very helpful and believe that most of them are members of this site LOL..
If theyre not they should be.
I cracked my screen and i dont have the box...... so how would I tell without opening it up, which one I have?
Just if I have to open it up and let it sit there for 3 weeks Id forget how I would put it back together
If you got your Desire after August (I think) or September then it would be SLCD otherwise it's AMOLED.

[FYI] AMOLED or SLCD - HTC response

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.
http://pocketnow.com/android/how-to-tell-if-your-htc-desire-has-slcd-or-amoled-screen
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.

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.
ie:

Without a magnifying glass though its difficult to be certain.
Do what I did:

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

Shall I swap for an SLCD?

I'm sure similar questions have been asked already but I find myself in a fairly unique position whereby my old phone was SLCD and Three UK replaced it with an AMOLED Desire under warranty. I can now either keep this one or complain and get it replaced. Which would be the better option in this scenario?

Depends on you, AMOLEDS draw approx 3x more power when displaying white pixels, has a higher chance of getting a burn-in, but they use virtually no power when displaying black/ dark colours. SLCDs performs better under sunlight when compared to AMOLEDs, and they don't use Pentile matrix.
I would never do it... Images looks more beautiful on the AMOLED, believe me...

Since you live in the UK where there is not much bright sunlight, you may as well stick with the AMOLED.
Engadget recently did a comparison of the SLCD and AMOLED desires and the AMOLED one came out with the better battery life. If I had both in my hands I would just pick the one which has the most honest colours.
The colours aren't really of much concern. There seems to be a slight pinkish tint on the AMOLED but it really isn't that bad. Nor do I care about seeing it in sunlight (I live in the UK). The only thing that slightly bothers me is the fuzzy text, but since I don't have them both side by side I can't do a proper comparison. What do others think of the layout of the pixels on the AMOLED display as compared with the SLCD?

Having held them both side by side today I would still pick the amoled, the low black levels make for am immense movie watching and e- reading experience ( white text on a black background is really restful foot the eyes to read) the only time text trading is a problem is the SMALLEST red text on a black screen, so hardly ever!

Hmm... I guess I'll just go to a Three store tomorrow and compare for myself. I'm very picky about this sort of thing and I don't want to have a phone I'm not happy with for the next 1 1/2 years or so. In a way I could be considered lucky being able to pick, but I find it's usually more of a misfortune in my case.
Anyway, thanks for the help.

[Q] Amoled Screen getting Yellow-ISH?

Hello,
I do deeply apologise if I am making this thread on top of some that already exist, I tried to do search, but did not find anything exactly like my problem...
Well, here it goes. I have the old version of HTC desire with Amoled Screen(I am pretty certain about it) but suddenly, I dropped my beloved on ground, and it fell flat on screen... digitizer and screen protectors were absolutely fine, but the inner screen cracked and liquid thingie got out, so after few days, I ordered repair on HTC, despite 85pounds worth repair, and 3weeks waiting, I finaly got my phone back... but there is something wrong with it...
I have read over the internet some talking about dust stuck between screen and digitizer, I have read something about digitizer not working as supposed etc. but my issue is different, the screen is Yellowish?!? Did some google search, and found that SLCD screens are yellowish, and AMOLED blue-ish, fair enough, did some research and checked differences, and NONE of the SLCD screens were that yellowish as mine, so took drop of water on screen to use it as zoom to find out if I have SLCD or AMOLED, according to engadget.com, I got another AMOLED screen, which makes me kinda happy(black is really black, viewing angles are good etc). but the color... I would not mind much, but its sooo yellow, that whats supposed to be blue is having slightly greenish color now... I can attach some pictures if you need, but I have nothing to compare with other than my LCD display on PC. I will actualy check tomorrow with some people from work who got Desire as well.
I also found one thread on this forum, that one lad was replacing the screen for himself, and that he found the problem is on some filters thingie(I dont understand such things that much, and I would not be able to fix it by myself) that was turning his screen yellowish as well...
So my main question is, could possibly the phone leave the HTC repair center in England with this kind of fault? Where the screen is yellow-ish and actualy turning colors of pictures different way?
Nothing is 100% perfect and we're all human, so yes, there is room for error. Take it back and say you don't like it. As far as explaining it to you, I have no bloody idea at all. If I was you I would take it back. Whilst we're on the topic, how do you know if you have an AMOLED or a SLCD screen?
I hope its nothing against rules, here is the best way how to know what display you have:
engadget[dot]com/photos/spot-the-difference-htc-desires-slcd-versus-amoled/#3354740
just focus on the bricks, if they are like on old phones, then you have SLCD, if they are like on wall, its AMOLED, the AMOLED has build its basics little zigzag, but SLCD is straight, just like on LCD screen on PC - you can easily notice while browsing the net and displaying straight vertical line, if its thin enough, you will see little edges on it
Other than that, I dont think there is anything else(appart from how bright colors are on Amoled) that would say you have AMOLED or LCD
I had a look but it was hard to tell how they were lined up. It seemed that they're all like a wall, I'm pretty sure but need a microscope lol.
It is easier to tell if you look at something that is blue or red, rather than white or green. If it is amoled it will have diagonal lines or a diamond pattern with black dots in them. Lcd will be entirely smooth with only horizontal and vertical lines.
Ok, so I have seen a friends amoled screen now, and I have changed my opinion now, the yellowish, and he has blue-ish color.. so mine screen looks way better and has way more contrast, so I guess I'll keep this as it is, and just get used to it... I dont want to use nokia 6070 any longer
You might be interested in the colour calibration that comes stock with e.g. Cyanogenmod if you have rooted the phone. There you can change the balance between R G and B to obtain a more natural white.
Normal cautions regarding rooting apply.
Gotta root first, since the phone came back from repair completely wiped out

Or you could put on a pure black background and see if the blacks are black! If you can see backlight then it's LCD.
True, that's a way how to find out as well, but I wasn't that certain with this since I didn't have different phone to compare..
Btw, phone rooted and runing gingerbread ATM, pretty happy with it, and screen settled down and colors are good again...
Just about the gingerbread, is there a hope for having sense on it before official launch? Or do we have any official news from HTC about gingerbread coming on desires?
