Is this Acrhos 101 screen defective? - Gen8, Gen9, Gen10 Q&A, Help & Troubleshooting

This lcd is really bad. In order to have decent reproduction, the screen has to be viewed at around 45 angle ( 0 - looking along the plane from the bottom, 90 - normal angle - line of sight is perpendicular to the plane of lcd, 180 - looking along the plane from the top).
At 90 degrees, the bottom 30% of the screen is dark and lighter colors disappear. Tilting the tablet from 90 to 180 degrees, the whole screen goes dark. Tilting from 45 to 0 degrees, the screen appears to be lighter, as if the brightness is being raised, but at least the colors remain.
Is this how majority of A101 tablets behave or is this tablet particularly defective?

My screen is the exact same way. It is horrible. There is only one viewing angle to get an accurate picture. I am curious to see what others are finding.

mine is exactly how you described it. not the best screen especially viewing dark images. lighter images are not as noticable

The Display Panel has an min viewing angle of 15° and avrg viewing angle of 20°.
(Got it off some forum post with the technical details of the display)
I first bought a 70 because the 101 wasnt available, got a 101 yesterday, returned it today.
The 70's display viewing angles waaayyy better.
I really don't get why Archos built the 101 which such a ridiculous display. I can't imagine any actual use for it.
Archos, what did you think!!

Muddy / dark band(s) on screen when dimmed?

Hi Guys - great phone which I've had a week or so now. Upgraded from the first Galaxy S.
Now I must admit to having very good eyesight (sometimes wish I couldn't see finer details!) and..
On white / grey images (download the various screen test apps to have a look for yourself)
The screen, when on a low brightness, is "muddy" and demonstrates a few vertical darker lines on the screen with mine showing quite a prominent one in the bottom right heading up about half way up the screen.
This is mostly visible when the brightness is at a minimum (regardless of auto or the powersaving options)
When the brightness is turned up it is barely visible, if at all... looks fantastic..
But.. at this point I preferred the screen on the Galaxy S which, when dimmed was more vibrant and didn't have this "problem"
Hands up who can see what I see? Any darker lines visible on your white / grey backgrounds? a side effect of this new subpixel arrangement? totally normal? some pixels not as bright in a row hence darker lines?
What do you guys think?
Cheers, B

Could you take a pic or something?
ASAP yes (no camera ironically so will have to ask a colleague!)
hold menu and press power button for screenshot off the device.
Yeah, mine set to minimum brightness and has some line artifacts like when LCD supplied with low voltage. (low brightness setting)
Easily noticeable when displaying grey colors.
I'm also using Screen Filter app, setting brightness even lower, some black points around 0.3cm is exposed at night.
Not sure those points are affected by anti-scratch film though.
Hola
I can confirm that I see the same "line banding" effect when using the device with low brightness. Like others have mentioned I also use the free Screen Filter app to get even lower brightness levels especially when reading stuff in bed in the near dark.
I would think this is a side issue with having the Super AMOLED Plus type screen but I guess only a Samsung tech can confirm.

65" long exposure exposing some black spots.(digitally enhanced)
Lowest brightness + Highest brightness.
Wondering those spots are caused by screen protector or defective screen or limitation of current AMOLED's.
You can see there is some current leak.(It should be bezel-like black if it is ideally off)

Not sure I understand you cpu98!
Is there a consensus we all have this "problem" - i'm on the verge of taking it back for a refund and "monitoring things"
Anyone understand the tech / spoken to Samsung?

Not sure what those black spots are... is your camera messed up? There's spots on the right even off the phone...
Also yes, pure black for SAMOLED still produces SOME light, but it's almost indistinguishable to the human eye.
Take a picture of a dark grey image on low brightness and it should show the bands the best...

That spot off the phone is on the wall not defective cam. As you can see photos are taken at different angle. And it is visible in naked eye.
Yeah I like its screen very much. That black issues are no problem in real use.
I'm very satisfied.

[Q] Odd display issue when viewing black backgrounds in dark surroundings

Hello XDA,
I've searched around for this problem a bit, and it seems this issue hasn't been brought up anywhere. If it has, then I apologize.
The S2 has an awesome display with great colors, blacks included, but I noticed this issue one night when I was watching a film on my S2. When the display is showing black/dark images you can clearly see what appears to be glue smudges all over the screen, especially along the rims. It is only noticeable when there's little to no other light in the surrounding environement. Increasing brightness seem to worsen the problem.
It is hard to describe and very difficult to capture on camera but I made an attempt. I can't post links yet it seems but here's an imageshack url:
img842.imageshack.us/img842/5420/blotches.jpg
The image was taken with a Canon 450D with 20 sec exposure (hard to focus when it's that dark I'll tell you). Edited slightly in photoshop to cut down the size.
Here you can see the general color of the screen (gray-ish) and some of the blotches of (what I'm guessing is) glue in the back. If I had to guess I suspect the blotches might come from the capacitive touch layer of the screen. Is this an issue or is it to be expected on phones like these? It's not a major problem but it's actually quite annoying when you're watching a film/youtube clip/playing a generally dark game or whatever. Should I return my device? I've used it for just about a week and a half.
Thanks in advance for any help.
i have this too, its the AMOLED display. you can turn the screen off and on and you'll see it go off n on. not the sgs, but amoleds generally. my omnia HD had this too (1st gen AMOLED)
the blacks are not 100% black i say
Im having this too, nothing to worry about this as it doesnt disturb the beautiful display of this mobile.

[Q] Diagonal Line on Screen at Top Right - MiniPro-SK17i-

I have noticed a cross line on the screen from Top to Right (Portrait Mode-below the Music Player / FM Shortcut). Though the same is not visible when at 180 degrees with eyes but visible when phone is tilted to right or left. With Lighter colors it can be noticed easily not visible with dark colors..
It has got no effect on the screen's visibility performance and no pixels seems to be dead. Only a brighter cross line.
Just curious and little worried if this is a problem and may turn grave.

Screen defect

Hello to all
As the title says it's another screen defect that this phone have
I have noticed a darker area, which make almost a perfect rectangular shape upper to left of the screen and it is visible only in some circumstances
- screen brightness need to be lower that maximum (the lower it is the higher this defect is visible)
- mostly visible on grey image (for example the market startup) see other images in the links

http://imageshack.us/photo/my-images/851/img0635ul.jpg/
http://imageshack.us/photo/my-images/864/img0633u.jpg/
not visible at all on black screen of course but when the screen is off and with a bright light (sunlight of a power lamp) in some right angles I can see some darker dots (looks to be some kind of liquid inside the screen) at the size of 5mm and also this rectangular shape (good eyes need here ) no picture for this because it is not visible with any camera
I wonder how came to this and is any possibilities to fix this such as those screen burners, could these help? or only a screen replacement?
PS: phone have no waranty
Thanks
Screen burns are permanent on AMOLED as far as I know. You'll either have to live with that or do a costly screen replacement.
Ah well, guess I have to live with it, not a major problem but it's looks a bit ugly sometimes.
Just read a bit more about amoled screen burn and it seems that the blue leds are the most that probably get weaker in time and causing this screen burn, and yes this is an explanation why on a blue screen this is almost not visible no mather of the screen brightness
Maybe burn all the screen with a white image, but I believe the result can be worst that this
Thanks

2nd Screen Light Bleed - Want other user opinions.

Hey guys so I just picked up my LG V10 2 days ago, I knew there were some issues with light bleed on the upper left corner of the 2nd screen but I crossed my fingers and hoped for the best.
The first night I had the 2nd screen off, however last night I decided to give it a try since it seemed like an elegant idea to have on this phone.
In the darkness of my bedroom the light bleed from the upper left was utterly atrocious, it actually fans out and extends into the other screen to about where the notification bar is (this is with the main screen off). The light bleed is also quite bright at night, it is very visible from across the room and really destroys the user experience.
I'll update with photos this evening as I want to know if other users have a significant problem or it's something that happens on every few phones and I can exchange for a unit that hopefully has less bleeding.
I'd love your feedback on how the 2nd screen bleeding WITH MAIN SCREEN OFF is for you especially in a dark room.
Yeah mineb does exactly that..doesnt really bother me too much
If you're in a very dark or completely dark room, you're going to notice light bleed. It's unavoidable with LCD technology. Mine also bleeds a bit into the regular display. Look at the screen directly (not at an angle) and it should look a little better. Angles produce worse backlight bleed - you're going to notice when you're laying in bed and look over at the phone and see the backlight bleed being a lot worse.
The big concern is if the backlight is actually bleeding in normal day-to-day conditions. On my first phone, I noticed in the STORE that the upper left corner of the notification bar was brighter than the rest of the screen. It had backlight bleed bad up there to the point if it being visible in daylight on colored portions of the screen. Exchanged it for another phone on the spot and it looks completely fine now. In most conditions the second screen appears to be floating because your eyes are adjusted to the brighter ambient light and can't see the poorer contrast ratio of an LCD compared to an AMOLED. At night though, you will definitely see that the second screen would have been executed better if LG would implement OLED in their flagship phones.
I see a little bleed on the left edge of the second screen, when the main screen is off, but it doesn't bother me. I kind of like that the notification icon is brighter than the rest of the second screen because it helps me notice that I have a notification, especially since the phone has no notification LED (shame). The second screen is not important to me, plus I don't see the bleed when the main screen is on which is when I'm actually spending significant time on the phone.
There reason you see bleed is because the second screen has a dedicated white LED on the left edge that's separate from the main panel backlight and positioned to "inject" light from the side without being properly integrated with the panel's backlight diffuser. This is why you'll see this, to varying degrees, on every unit. When you're in a well-lit room with the main screen on, the second screen looks perfect, because that secondary LED is off when the main screen is on. Also, the second screen auto-dims based on the amount of ambient light, so you might see the bleed on the "high" mode when you first turn off the main screen, but not when it dims down to the "low" mode after a while. Maybe they'll introduce a new hardware revision that repositions the second screen edge LED or does something else to limit its bleed. We'll know in 1-2 months when the next batch of V10s hits the stores.
I replaced my V10 twice because it had yellow bleed at the BOTTOM of the screen by the navigation buttons and that annoyed me as hell, since it affects the colors of everything I do, especially watching movies. All three had second screen bleed. What was particularly interesting is that each had a different color temperature screen. My first one was reddish, the second one was blueish (like the G4), and my current one is greenish, it actually looks exactly like the Nexus 6P screen (I put them side by side to compare).
I'll agree with Nitemare3219's and siraltus' observations and comments. When the main screen is on nothing is really noticeable. When the main screen is off I have the second screen off. It's so dim I don't see the point to having it on. The second screen is a bit of a gimmick. If I had additional issues I might think of exchanging it (still have 10 days), but I don't notice any other screen issues, and my fingerprint reader works...with a case. Every LCD screen I've had has had some sort of bleed. The problem starts if it is noticeable during normal use/viewing.
Mine slightly lights up the whole right corner 1/5th down the screen, only visible in a dark room. I dont get bleed from the right like ive seen in pictures and youtube.
It's only noticeable when it's pitch black and my main screen is off, so it doesn't bother me at all. It's not noticeable any other time.
First the second screen has already become a staple of my use habits, it's no gimack. Yes bleed is there when main screen is off, no I don't like it, but don't feel it's as big an issue as some make it out to be. That's just me though, I can see it bothering some.

Same, the light bleed is noticeable in the dark, but not bothersome. It is not nearly brought enough to light up my room at all, and is very slight in the upper left corner of the second screen. For the usefulness of the second screen with my usage, it's an ok trade off for me.
If your not happy with it and your within the 20 days id return it. I did return my initial one and my second one is better with less bleed.
my bleeding is always noticeable but especially on dark rooms,
I posted the pictures here:
