[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.
Regard Malcolm

well, I don't know which one is better, but on the normal box (white and tall with a full size desire on it) it says at the back.. Specifications Display 3.7-inch AMOLED touch-sensetive screen
hope this helps! good luck!

AMOLED is way better
has better battery life

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.

Is it this simple to tell the Difference

Hi all.
See the below post for pictures of the differance with the screens and boxes. Also details of them.
I didnt and possibly am stuck with the Sled version.

To bonit2,
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.

Odinbear said:
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 ?!

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...

To check if my Desire is AMOLED or SLCD

I have checked on my Box,
specifications are :
Modèle : A8181
Affichage : Ecran tactil 3,7 pouces
there is no specification for the kind of screen AMOLED or SLCD.
any idea ?

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?
thanks

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..

Ah, nice Odinbear, that's some good info you got there.

Happy to help

Cheers, BigMango.
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.

[Q] SLCD and AMOLED... something weird is going on here...

OK, check this out. I rooted my Incredible, and I had problem after problem with rooting because of what I THOUGHT was an SLCD issue (I lost all function of my touch screen whenever I flashed a ROM or kernel, even if they were compatible with both screens). After 3 days I finally found a combination that worked.
My husband wanted me to root his phone, and I wanted to physically see the difference in speed between rooted and stock while doing a Web search. Well, when I put the two side by side while on Google, there was a blatantly obvious difference in the screen color. My screen had a pink tint and his was crispy white, to the point that it almost hurts the eye to stare at.
So, I downloaded the "mirror" app (which is just a black screen that shows your reflection) and yep, sure enough, I had a bit of brightness on mine, and his was just black as night.
Both of our phones had the 003 under hardware, which is suppose to mean the screen is SLCD, but mine is clearly AMOLED.
I am thinking, since they were both refurbs sent as replacements, that I got a phone that was originally produced with an SLCD screen but it got replaced with an AMOLED.
Could this be the reason that when I flashed a ROM I had no touch screen function? Could there have been an incompatibility issue between the original hardware and the replaced screen that got triggered by trying to flash a ROM?
This is kind of blowing my mind right now...

Interesting twist..
I'd think that just after rooting & first reboot to recovery of first (your?) DInc, whether or not you saw CWM would indicate screen type.
On the other hand, that variable is complicated by which Unrevoked version was used - SLCD had no recovery built into Unrevoked until recently.
Curious to know how this shakes out.

I may be mistaken but
AMOLED screens give a grayish hue not pink due to blacks being their true color, just like slcds true color is white so their blacks are gray
So that being his would be black as night due to it being Amoled and true blacks
While yours is slcd because its grayish
A better way to test is to find a vibrant picture to compare, and yes this is obvious
The phone that has a duller yet clearer picture is SLCD
The phone that has the.more vibrant picture is Amoled
And its to my understanding that if u mix up sense/aosp kernels the one function you lose is touch so maybe u mixed up the wrong kernel

I used unrevoked 3, which is suppose to be compatible with both... although I got lazy once and tried to flash a ROM through ROM manager. It prompted me to install clockwork, and I read that no issues were had doing that, so I did it... and of course I got the black screen /white lines. I had to update my recovery image through hboot. This tells me I have an slcd, which confuses me all the more... not unless I am confused, and my husband is the one with the amoled screen. Either way, it is strange because there is an obvious difference in screen appearance, but both hardware versions say 003.

That is what is so confusing. The white on my screen has a washed out /dirty appearance next to his, and yet his screen was black black and mine had a dark gray /purplish hue when looking at an all black screen.... yet I had the black screen /white lines when I "updated" clockwork. This plus the loss of screen function tells me for sure that I have slcd, but the display /colors tell a different story.
Like you said, amoled whites are washed out, and slcd blacks are grayish, yet my screen displays both properties.
I wish this was something I could capture properly on camera...

[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?

[Q] Difference between Desire(s)

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?

How to know IF AMOLED OR SLCD?!

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.
http://184.72.239.143/mu/59498a86-75ee-c9c6.jpg

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.
