i love the Focus Samoled+no LCD ghosting - Focus General

if you get a chance to try an HD7 for yourself and compare the lcd with the focus you will see some Ghosting on the HD7 when flicking the screen in the Home and App screen much like comparing a 60hz lcdtv to a 120hz lcdtv
i thought the tmobile display i played with in the store was defective because i could clearly see a ghosting effect which has been confirmed by friends of mine who own the HD7
now that pentile display driver is easier to bear with

Screens: LCD vs AMOLED

The one thing I wish the EVO had going for it is an AMOLED screen. I'm coming from a Nexus one with said screen, and it's gorgeous. Almost useless in direct sunlight, but gorgeous. Now their was an early Sprint ?Coming Soon site claiming the phone had an AMOLED screen http://www.androidguys.com/2010/03/28/sprints-htc-evo-4git-sizzles/ ---but this was prob an error. My question is: is their a huge, noticeable, difference in the two types of screens? EVO owners, give me your opinions!

Just had a live evo in my hands, and the screen is a beaut. I wouldnt worry about it not being AMOLED at all.
The screen is really a great screen.
I really don't notice much of a difference in colors / contrast / etc when compared to the ZuneHD, maybe it's the higher resolution / size that makes it look just as good.
meh, on the whole, AMOLED is all hype no show
AMOLED is trash I have a Nexus and an Evo and in direct sunlight my EVO is noticeable, AMOLED drains battery, LCD saves, colors are sharper but not brighter on AMOLED, brightness all the way up they both match up but the nexus(AMOLED) has a sharper scene
all in all not a big differ and Evo screen (IMO) has a better screen
1- colors are the same but sharper in AMOLED
2- direct sunlight LCD wins
3- colors are both bright
4- LCD battery saver
just a few details!
I thought that the amoled was more efficient.. so better than lcd

Phone Scoop comparesEvo screen to Nexus One Amoled
See below for review comparing the Evo screen to the Nexus One Amoled
Here is the link to the full article.

Screen
The screen on the HTC Evo 4G was, at times, a bit disappointing. Under medium indoor light, the screen is crisp and clear. Text looks sharp and legible and the dark, contrasty interface looks polished. Outside, the Evo 4G couldn't hold up to bright daylight. This made it tough to use for normal email and calling tasks, and nearly impossible to use the camera, since you have to tap an onscreen button to take a shot. In almost every way, the screen fared better than the AMOLED display on the smaller Nexus One. It was a bit brighter with warmer colors and much better outdoor performance. But it could still stand some improvement.

Incorrect, AMOLED has no back light and consumes roughly the same power that a TFT LCD uses just on the TFT portion of the screen. The TFT Portion of a Active Matrix OLED screen controls light on a PerPixel basis, illuminating each OLED pixel at whatever color is required vs LCD where the current is constantly on(except in a pure 0 0 0 black pixel) and controlling the Liquid Crystal portion rotating the LC to whatever degree to allow the backlight(A large % of the consumption) to shine through at a given color. And because of AMOLEDs aforementioned lack of back light it uses significantly less power.
I'm also confused as to what you mean by "color sharpness" Are you talking about the actual edge sharpness of an image or the color reproduction.
In which case the color reproduction on a AMOLED is more SATURATED not specifically more accurate, though the increased saturation makes the image appear better on average because most people enjoy over saturated images. The contrast ratio, which is the ratio of black to white, e.g. when a TV says it has a 3,500:1 contrast ratio then the luminance of a pure white pixel 255,255,255 is 3,500 times higher than that of a pure black 0,0,0 pixel. AMOLED displayes typically have a much higher contrast ratio due to the lack of a back light and the fact they can produce much "deeper" black pixels.
AMOLED actually bugs me, not only are they useless in direct sunlight(which I find myself under quite often) but it feels like colors are often OVER saturated, like the reds and oranges on my friend's Incredible look awful while I've never had that with my Hero, some colors on mine might be washed out but I'd rather have that than have a giant hodgepodge of colors on an AMOLED.
Another thing to consider is AMOLEDs "burn in". That means that pixels that do not change on the screen for a long time tend to burn in and show permanent shadows. This happens on the status bar a lot since it is nearly always displayed and unchanging.
Here is a thread of NexusOne owners documenting it.
http://forum.xda-developers.com/showthread.php?t=673513
As of last week I just switch over from At&t to Sprint wireless. I had two lines on my contract, wifey with the Samsung Moment and myself with the HTC Hero just to hold me off until the Evo release.
From what I thought isn't the Samsung Moment screen also uses the Amoled technology and the Hero is LCD?
Side by side comparison from low brightness to 100 percent, the Hero display looks so much better quality wise compare to the Moment. Hero seem more saturated and crisp whereas the Moment IMO seem much more dulled. Especially in the setting menu with the black background, the Moment is kind of like greenish black whereas the Hero is spot on black. Outside I'm having a very difficulty time navigating around Moment (brightness all the way up) whereas the Hero is still manageable.
By any mean I'm no expert in this display stuff but this is just my own little comparison of what I've seen between the two display.
Anyone know if the Evo screen is transreflective? A related question would be, is it even possible for AMOLED to be transreflective?
I compared my Evo screen with my old Hero screen and the Hero was a little brighter and with darker blacks. Even between LCDs there are differences.

[Q] Dell AMOLED vs HTC HD7 LCD?

Everyone has been raving on the DVP's screen, but having had the HD7 while waiting for my DVP to arrive, I've gotta say - I have mixed emotions!
While the colors are substantially better side by side...anyone notice how pixelated the DVP's screen is on text and such? The battery indicator is a good example of what I'm talking about...
I think I might actually prefer the LCD of the HD7 better, despite the lesser black level and color saturation.
Anyone else have any thoughts?
I see what you are talking about... I didn't realize this before you mentioned.
AMOLED in VP is a little bit too much saturated and the HD7 is a wee bit too washed up
A middle ground would have been awesome.
Maybe SLCD or SAMOELD hits that middle ground. My friend is getting the Captivate, will compare this side by side and let you know.
I have a slight blue tint on my whites at certain angles. I dont see a big difference in the two screens, but i expected more from the AMOLED.

I think that was my big let-down. I had (probably overinflated) high expectations of the AMOLED. I didn't see much on the net talking about it, and in fact, most reviews talk about the sharpness of the display, so I was confused if it was just my unit?
I *WAS* able to find a couple of sites that talk about AMOLED having sub-pixels vs a standard LCD/SLCD, and therefore it's not as good for small text or sharpness...
I must say, though, I love the keyboard, and I'm still going to keep the DVP over the HD7 - just a little surprised at the lack of impact from the screen, considering what they've done to build this device (gorilla glass, etc).
I agree with you on the fact that the AMOLED on the dvp has noticeable pixels more than the HD2 that I have. What’s even more sad is that they have the same resolution yet HD2 has a larger screen – Thus I should see more pixels from the HD2, however, this is the opposite.
Why does the DVP have noticeable pixels? Can anyone compare this with the Nexus One and see if they are the same?
Pen-tile matrix effect, probably what you are seeing here. However I cant see what scenario would occur to make me prefer the washed out screen of the HD7, just too darn low quality for me.
Its the nature of the AMOLED screens, my Focus had the same thing. However, overall, I find the screen on the DVP far, far superior to the HD7.
it was my understanding this is more a fault with windows phone 7 as it does not use 16m colours like the display can do.
Personally owning both.. the DVP has a MUCH better screen. Especailly if you change brightness to high.
ive never see an amoled screen before, but coming from the HD2, i was very disappointed.
i guess the hype of amoled screens made me have high expectations which were too high by the time i saw a real amoled screen.
Now that I have a DVP in hand all I can say is the difference is clear, the Dell's AMOLED screen is superior. Maybe some are being swayed by the size but for someone who has had an HD2 for almost 9 months the size is not really a factor and the lack of colour, dim lifeless screen is just no competition for the AMOLED on the Dell.
HD7 Advantages
+Noticeable advantage in color accuracy
+Larger screen offers better spacing on keyboard (portrait)
+Good black levels while inside optimum viewing angles
+/-Brightness is more than adequate (auto brightness is a little conservative though)
+/-Decent viewing angles (No issues during regular use)
HD7 disadvantages
-/+Decent viewing angles (Poor viewing angles make kickstand less useful)
-Slightly less responsive (my opinion)
-Lacks sharpness while viewing pictures (not sure why but they aren't as sharp as the rest of the time with the HD7)
-Color saturation could be better
Venue Pro Advantages
+Excellent contrast with fantastic black levels
+Slightly more responsive touchscreen (my opinion)
+Good brightness
+Excellent color saturation (somewhat oversaturated though)
+Perfect size (my opinion)
+/-Sharpness (pixels aren't noticeable during normal use)
Venue Pro Disadvantages
-/+Sharpness (some users may notice more pixelation)
-Very high color temperature (extremely unusual coming from a calibrated display)
-Can't use the brightness to your advantage without battery drain
-Keyboard felt a little cramped coming from the HD7
I miss the color accuracy of the HD7 but love the size and responsiveness of the Venue Pro. The HD7 gets a bad reputation because of viewing angles but during normal use this is a non-issue and possible advantage with curious onlookers (there will be plenty). It offers better black levels and shadow detail than the iphone 4 but gets hammered for viewing angles. The Venue Pro offers fantastic build quality, an almost perfect size (my opinion) and a more responsive touchscreen (my opinion). It has a very high color temperature but offers superb black levels and color saturation. It is also sleeker than I had anticipated from all the comments saying that it is a beast.
Sorry for the double post
Samsung has bastardized AMOLED with pentile imo. It prolongs display life but the tradeoff in picture quality is too great. There are AMOLED's with normal subpixels, and they look fantastic (Cowon S9, Zune HD, etc).

That's a great point - the ZuneHD I have looks amazing! Still loving my phone, though...
Zoom Sharpness?
I purchased the DVP to have something that will show my pictures a little more accurately than the LCD I have on my HD2 (the slightly extra saturation is better than the washed out look on the HD2) but I now find that there is no sharpness to the images when zooming in.
I have a photo of the lights of Chicago at night and when at the full screen zoom level, it looks ok but zoom in and it is a blurry mess. My HD2 is very sharp when zoomed.
In the Zune software I have tried full size pictures compressed by Zune, pre-compressed images with Zune left on "Original" with no compression and nothing seems to make the images better when zoomed.
Anyone else seeing this problem? This could be a deal breaker for me as far as AMOLED screens go unless it is a WP7 problem. I would love to see how my images look on a Droid device with AMOLED.

I agree with you. Images seem way too pixilated. I mean, I can actually see them which is so sad when I compare it to the HD2. When I am going to do is wait for WP7 to be release on the HD2 by Cotulla and then compare if it the OS or specifically the DVP.
Has anyone seen another amoled screen before in real life? This is my first time I’ve seen an amoled screen. I am not impressed…. At all. Lol but the colors are lovely. Image quality drops, while color saturation grains points
If you read the Cnet phone screen shootout you will see that the HD7 has some pixelation on images of text when zoomed. I have also seen some softness and pixelation on my wifes HD7 when zoomed in. This only really seems to be when viewing images so I would guess it is OS related and not specific to the Venue Pro.
I own a Nexus S and DVP and the dell is getting returned today. Main reason is android is a better fit for me but close second is NS screen is head and shoulders better. No pixelation like I had on dvp.
I think I had a lemon too my dvp was freezing quite a bit.

I find this odd. I had a Focus and an Epic 4G - both have the same screen as the Nexus S - and they had the same pixelation issue as the DVP. It has to do with the AMOLED screen.

Amoled or super lcd?

I heard that only at first Htc used Amoled display for Legend, and later on Super lcd. How to check the type of our scrren (display)?
Sent from my HTC Legend using XDA App
read the specs on back of the white box the legend was in
I just know about AMOLED Devices.
The switch from AMOLED to SuperLCD has been done at the Desire and as far as I know not on the Legend
I am very satisfied with display on Legend. Is there any significant difference (better or worse) with S-LCD?
well i compared it with a SLCD htc desire and i think the AMOLED is much better
Legend only uses AMOLED anyway, don't worry about it
S-LCD almost the same that amoled, only maybe contrast have some little difference
if i'm not mistaken
s-lcd
Super LCD is much nice when reading text and websites AMOLED is better for watching video,
SLCD is much sharper but isnt stand out bright and over saturated like AMOLED which is fuzzy and soft around sharp corners like text
look here and it shows you actual pictures were you can see the difference

Note though that the Desire AMOLED had a PenTile arrangement which seems to account for the marked difference in the shift to SLCD. The Legend's AMOLED screen uses a conventional RGB arrangement so probably wouldn't have suffered the same comparisons had it also moved to SLCD.
This page has a good breakdown of the differences.
http://jtra.cz/stuff/android/htc/desire-vs-legend/display/index.html
Yes, you are all right. I have bought desire z and I can see the difference. S-lcd is much sharper, but amoled has much better contrast - black is really black

Some webshops often say that the black HTC legend is equiped with LCD and the silver one with AMOLED. My collegue has a black one, I have a silver one and both have amoled.
You can easily see the difference when you tilt them. Amoled's colors almost don't change (even if you're almost at 180°), LCD's colors go weird...

Oh, Thanks ! Is that the simple way to tell ?
My new Virgin Mobile Canada Legend's box says AMOLED but I think the box is lying. Wonder if I can sue somebody, LOL, jk. I guess HTC may be at partial fault too since their spec page claims AMOLED: http://www.htc.com/www/product/legend/specification.html
I recall some article quoting an HTC rep saying the "backward" move to LCD would save power, but then tests (and common tech sense?) showed that was a lie. I originally was disappointed at the loss of AMOLED, but from what I've read though, I'd prefer LCD if given the choice, simply due to the better legibility. On the down side, LCD takes more power, doesn't have the deeper blacks and colors, and may be a bit harder to see in the bright outdoors.
Bell supposedly dropped the Legend because of the AMOLED supply issue. AFAIK all of the later (after last summer or there-abouts ?) Legends are LCD. Would be nice if we could tell via serial numbers or something.
My Legend's colors start going weird somewhere around 170 degrees or so (just a rough guess). So I guess I have LCD ?
You could also take a cheap microscope and look at the screen. The difference is startling. Amoled will be made up of a lot of lines, more red than blue (I think). LCD would look completely different

With the screen on and white, right ? I tried this with a jewelers loupe and see lines about twice as high vertically as horizontaly (with the phone speaker up and mike down). It looks like there are thin red lines and thicker green lines that are somewhat blue-ish.
Would there be any difference in device drivers loaded ? I see a driver in dmesg with "oled" in the name.
This microscope diagnostic method will not work on Legend and it has an RGB matrix - the Desire LED had pentile matrix.
All you have to do is display a mostly black screen (the android settings menu is a good example), find a dark environment and look at the display. An SLCD will seep light from black areas where an LED will be an almost perfect black.

i can notice his display has slight better screen in the menu like smoother or something but on the legend view aspect is higher than on the desire....

Just got my Focus

So my HD2 touch screen decided to die on me and my work has been trying to get me to jump on their AT&T plan. I was hoping to hold out until the HD7S showed up on AT&T (which I now think it never will) but since it's not available I went with the focus.
After using the phone for a few days I really like it. The sound quality is better than my HD2 (running WP7), call quality is excellent (but the focus gets HOT compared to the HD2) and I really like the camera quality. Pictures look really good.
So the bad - and this part confuses me. People were raving about the screen quality of the phone, that the super AMOLED screen was incredible. I think it's terrible! The pixels are the size of waffles compared to the HD2 (yes I am exaggerating). Yes I can see the screen in sunlight better but that's it.
I wanted to get the opinion of some focus users. Do you think the picture/screen quality is good on the phone?
It's certainly not an outright deal breaker but I might jump on the HD7S if it comes out within the next month.
So to recap: Love WP7, love the focus sans the screen and hate AT&T
Mate, I own a Focus now too.
I owned WP7 phones in this order: LG Optimus 7, Omnia 7, Samsung Focus.
One of my friends has a HD7 so I can say I've seen the first phones closely. I think one of my first posts here were about the quality comparison between these phones.
To summarize it, put side by side, the phones are:
Screen size:
HD7>Omnia7=Focus>Optimus7
Screen quality (I know it's subjective but I'll detail later)
Omnia7=Focus>Optimus7>HD7
Battery
Optimus7=Omnia7=Focus>HD7
Phone build quality:
Omnia7>Optimus7>Focus>HD7
Sound quality (overall)
all seemed about the same
That's my impression.
Now about the screen. Put side by side any LCD (Optimus7/HD7) screen with the same thing on alongside Omnia7/Focus and you can't miss the difference. Also, if you're complaining about the size, I can do that too. I can't use only one hand to tap all across the HD7 's screen, I need to use my other hand as well, while on the other phones I can do it with one hand.
To summarize: The contrast, brightness, colors, legibility is simply better on Amoled than on LCD.

The contrast is better and so are the colors but I have to say that's it. At least when comparing the HD2 and the Focus. I am watching netflix, looking at pictures and reading web pages side by side and the HD2 picture is more crisp and text looks better.

That's because Focus screen, which is Super AMOLED, currently uses Pen Tile subpixel arrangement that have half the number of sub pixels as normal LCD screens. It could be problematic to some but not noticeable to others (like me). Next generation Super AMOLED Plus will double sub pixel count and a few other quality improvement.
If you can overcome this subpixel deficient issue, the screen visual quality, especially the contrast, is next to none. Some might argue that the color is too satuated.
I personally will take contrast over pixel counts. Can't stand the forggy screen. That's why I only buy Plasma TVs vs LCD TVs. Die hards would willing to spend $3000+ for a used (no longer in production) Pioneer 50" Kuro plasma TV over any fansy new TVs today because they know how to cheerish the superior black level (and hence the contrast) or a Kuro TV that none of today's HDTV can match.
Also, be careful of screen burn in. Don't let bright text display on the screen too long. OLED screens are very suspectable to burn in because the pixels have a very limited life span.
I hear you on the contrast - I own a 50" Panasonic plasma that I will be hard pressed to part with. I like how the picture looks compared to most LCDs.
I just looked on AT&T's website and they are showing the HD7s on the list of wp7 phones with a coming soon tag. That just happened today so maybe they really are getting it soon. It's got a really nice super LCD on it and once it's in the store I will compare the focus and it closely and get the one I like best.
One point that may keep me on the focus though is the camera is a lot better. I took some low light pictures on the focus and they came out great. On the HD7 - not so great. Maybe the HD7S will be better but we will see.

How good the HD2 is - comparison

I flashed WP7 on my HD2 and set it to match my Focus them and layout. I always knew my HD2's display was good but now I have proof of how good. To me it matches the color richness of SAMOLED but doesn't have the ugly pentile look. It certainly looks better than the HD7 I had.
The focus seems a bit clearer, but something I've noticed with every amoled and super amoled panel is there is always a blue tint to it.

Yeah...in the picture it does look slightly clearer. I don't know why because I took two shots and that one was the better of the two and in person the HD2 screen is just perfectly clear. But the color production is what stuns me. To me it looks identical...except for maybe the black depth.
I have noticed the blue'ish tint you are talking about on my Focus and have commented that my iPhone 4's display is better than SAMOLED for color accuracy, viewing angle and quality. At the extreme viewing angle is where I see the blue'ish tint mostly and it is absent on the iPhone 4 display. Yet the iPhone 4 display has just as sharp a viewing angle. So it puts it above SAMOLED.
I had an HD7 when they first came out on T-Mobile and thought it was the stuff. Since flashing WP7 on my HD2, I am so amazed at the picture quality my HD2 puts out that I would much rather have the HD2 display in my HD7. I just got done with a little Angry Birds play ...the first time on my HD2 with WP7...and the colors and vividness of it just floors me. I've played Angry Birds on it a lot with Android. But WP7 Mango must be handling the display better because it just purely looks gorgeous.
I decided to take a look at the light theme and low and behold, it looks better on the HD2.
