*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

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

If you have two horses, one drinks 5 liters of water per day no matter what is doing, and other drinks 2 liters doing nothing and 10 if runs all day in full gallop, which one drinks more?
Consider you need additional 200 liters everyday to clean them and stables. Does it matter at all which one drinks more?

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..

Google chose to stop selling Nexus One instead of putting LCD monitor to it.
This decision says a lot.

Sorry, but I don't think the AMOLED shortage had *anything* to do with Google shutting up shop on selling the Nexus One!

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.

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 !!

AMOLED screen is a bit yellowish.

Anybody notice that their screen is a bit yellowish? If yes, is there a fix or should I go to service center?
Appreciate any response. Thanks!

That's something new ! My was pinkish before, but isn't anymore...

I guess this has to do with the calibration. As a graphic designer I know that screens should be set to a warmer spectrum (yellower) to display colours more naturally.

Mine is a bit yellowish too and my colegues have those that are a bit pinkish. I thought I was the only one with yellowish amoled BTW in Gmail app gray color looks gray, unlike on pinkish amoled. I kinda like it this way. If anyone finds out this is a hardware flaw please let me know.
Cheers!

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?
Thanks

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] Desire display issue

Hey guy,
So a friend of mine had a strange problem with his htc desire
Last night while reading some stuff his displayed color changed,
first thing i noticed was the rly pinkish tint, everything was slightly pink Oo
noticed this Thread but that wasnt the issue here
hope u guys can see sth, it seems its only 8bit color depth, 256 color
since some pictures are getting some rly ugly "blocks" in it
Well my question is, is the display broken? should he get a new one?
can a new rom fix this problem?
Thanks in advance
Kemo~

Try resetting brightness to auto.

we did that already, the pink tint increases with lower brightness
we also did a hardreset of the phone nothing changed
When i take a picture with ddms.bat it looks normal
its rly strange :/

Is it an LCD (slcd) or AMOLED Desire?

Its an amoled
Sent from my HTC Desire using XDA App

The AMOLED screen on the Desire has more red pixels (not quite right, but the easiest way to put it) then blue or green. What this means, is that the screen of the Desire is inherently tinted red. This is mainly more noticeable when the brightness is at low level as the color spectrum on a screen uses light to adjust the colors. With less light, the red has more of a bleed through effect and becomes noticeable. I really don't notice it unless it is at VERY low light or I have the screen with a white background and next to a device with another high end type of display such as the iPhone 4 or the Galaxy S which don't have the bleed through effect... well, with red anyways... they have the effect with blue.

Strange... I've seen oled displays look like that after only a year but that's in very rare cases. They wear out but not just like that if it happened almost insantly.
Did you look at the display just when it happened, did the other colors just sort of fade away or did they go in a snap?

it happend in an instant, an no i didnt have a look at it when it happend
but it seems the display is broken
well he gonna replace it, lucky he still has warranty =)
Thanks guys for the replies
Cheers

How's the screen on the Desire?

Hey guys, just wondering how good the screen on the Desire is. I've heard some pretty bad things about it and was wondering if the "pixel problem" actually affects the display.
How are HQ youtube videos/regular videos? How is picture viewing? How's the phone while in bright sunlight?

Well.. talking of the screen.. I'm having the AMOLED version.. first generation Desire's.. It's actually very clear.. although, I'm having a similar 'problem' ? With some light angles.. I see a pattern of very small dots in the AMOLED screen.. those are not dead pixels.. but in the glass I asume. Anyone having similar stuff ?

A8183 with SLCD here.
Screen is awesome! I have moved from a HTC Touch Diamond 2 to this. Great screen.
I haven't tried Youtube, as I have a computer for that. Pictures are as good as any phone I have seen, including the iPhone 4. Bright sunlight can be an issue, but much better than my TD2, which I can only assume has an LCD, not an SLCD.

The screen is great! I haven't noticed the pinkish tint that some people reported, i think it was fixed. Mines the Amoled version

I've had both AMOLED and SLCD and can honestly say that neither screen will detract from the wonders of the Desire.
The AMOLED display has amazing viewing angles (IE from every possible angle, it looks great), blacks are black, and colours are fantastic.
With the SLCD display, colours are more 'natural' (less vibrant, which can sometimes, though not to me, seem overwhelming). That is about the only thing i can think of that is better than the AMOLED in comparison. A downside is that blacks are backlit, and look a dark dark blue-grey. This bothered me greatly to begin with, but I have become accustomed to it now. Also, the viewing angles are nowhere near as gooda as the AMOLED display.
In sunlight - neither display is better than the other, and both are pretty terrible at maximum brightness. But then again, I don't really make it a habit of using it in the sunlight.
Pictures look great on both, and so does video, with the exception of dark scenes, where the blacks on the AMOLED look fantastic, and no so fantastic on the SLCD.
At any rate, neither suffer from any problems that affect usability in the way you describe.
Oh! And in response to the comment about the dots: I think they are part of the touchscreen circuitry. I can see them in certain angles, too.

Very nice screen indeed, the AMOLED version at least. Kind of annoying in direct sunlight though

I have a pvt1 1st generation desire with an amoled screen, and have never had a pixel problem :-D

I have the amoled disire, the display is fantastic unless you're beneath the midday sun

I actually prefer the slcd screen on my desire to the super amoled on my dads sgs. the colours just look to in your face on the sgs, and much more natural and easier on the eyes on the desire

The screen is amazing! Although the touch part of it is horrible.
