Touchscreen grid visible on display with strong light - Xiaomi Mi A1 Questions & Answers

Am I the only one with the touchscreen grid visible with a strong light pointing on the display turned a little bit on the side? I can see the small rectangles of the touchscreen grid if the display is off and I use a strong light on it

No, but it's normal.

Yes i noticed it too, bunch of square blocks. I guess it's the digitizer. I have mi4 and redmi 1s and they have this kind of grid aswell although with different shapes. Fortunately my samsung a3 2017 does not have that.

Yep. Have it also. But I really liked it. Looks kinda nice. Lol

Display light leakage on top corners of my X1 Screen? anyone?

Hi,
When I dispay a black background color on my X1 for example the pannel screen while it is switching to a different pannel or standard pannel I see a bit of light leakage on the top 2 corners of the screen from each side. A bit white, if you understand what i mean.
Does anyone notice that?
Thanks for the info
Yep I notice it too. Probably a case of bad backlight LED placement.
This screen doesn't seem to have as good a contrast ratio (black levels) as the one on the Touch Pro.
it's rather massive. Its even visible on camera mode when you have wide-mode off.
I hate living with imperfection.
How bad is it on your device?
I have to say its not visible when other colors than black are displayed
I'm probably seeing the same thing as you are - two bright areas on the top/left edge of the display.
The light is "leaking" because the display contrast isn't high enough and the screen assembly is a bit thin.
It's something I can live with, but I do wish SE had sourced for a better display. HTC has raised the bar since Diamond and Raphael, and this one is pretty good for a Windows Mobile device, but there are tons of even better screens out there - think Japanese super-keitais.
humm.. I was trying to look for the light leakage but I can't really seem to see it.... perhaps you could post some photos of what it actually looks like?
yup, it's there
don't see any leakage on mine...
I tried one in the shop and the screen was tilting left a little bit. Also the flip was a bit loose even in closed. Any comfirmation?
I'm pretty sure all devices have the same leakage problem. Just put on a pure black screen and look for the white cones decending from the top corners.
It's because of the led's behind the screen I guess
honestly, there's very little (leakage, short of better term) if not none. If you have seen TouchPro, it leaks like crazy...
Leakage is pretty terrible, no doubt about it. Wonder if this fault is only on some handsets?

My TP don't have this at all. Virtually no leakage. Pretty much solid black even in pitch black environment. Contrast and viewing angles are excellent. One of the best if not the best screen I've seen to date. Seems like they're using 8 bit panel instead of 6 bit TN panel. The latter have terrible contrast and viewing angle as standard.
lucky if u only seen it on top corners, mine are on all corners!
i don't see any leakage... went into a pitch black room and pressed the panel button and i see no white light coming out of the corners...

then you must have a rare TP, all the TP owners in Singapore reported to have the same leakage. that's if we are talking about the same thing with regards to light leakage...
Hi,
2 days ago a friend of me and me bougt this moblie,
yesterday i gave it back to the store, cause i've seen the white
leakage on my display too, on the devise of my friend its ok.
today I'll get a new one. Hope its ok there....
Thought it was damage or so....

Maybe I'm missing the point here. Do you mind posting a screen shot of the issue so we can be on the same boat? Now you've got me curious.
I'll try and post a photo when I get home later, mine is mainly in the bottom left half of the screen and it's really noticeable and distracting when viewing something dark.
Hmmm, I've definitely noticed leakage on my xperia, in the bottom left hand corner when in landscape.
I had a Touch Pro for a few weeks before I got the xperia, and the screen on that was flawless. I might give vodafone a ring and see if I can get it replaced...
Don't forget to switch the display brightness to full to be able to observe the leakage. When I watch the Bond trailer I can definitely see the leakage on the top corners when there is a black background in the beginning. It's rather distrubing but I do believe that all devices have that in some sort of extent. I think you just have to get used to it and live with it.

oled screen issue?

can you guys try this out and tell me if you see this on your screens. first turn down the brightness and go to a web page with lots off black text. on my screen everything black leaves a faint line across the screen wherever there is a black pixel from right to left. do you guys see this? out is much less noticeable when the brightness is turned up.
I've seen a tiny hint of this in my screen, but it hasn't bothered me. If it's severe in your phone, you may want to contact HTC.

yes I notice this as well but I have to say that is only noticeable with backlight set to minimum, and i think it's a normal behaviour of an amoled screen. Now I have one question about the screen too:
When I'm watching pics or movies the screen has a very good resolution. For all the rest the screen seems a bit dotted and grainy, especially with text. For example in the app launcher where the app's names are written in white and the background is black the text is not extremely clear and if I take a closer look theres seems to be pink pixelss on the letter's edges. I can notice this thing almost evrywhere but I think it's a lot more clear to see with text and the backlight set to max. do you manage to see this too or do you think that's because i have a defective phone?

the grainyness on thin objects like text is 100% normal, its just how these OLED displays work.
This guy did some awesome research into the graininess issue using a macro lens on his camera. Really interesting stuff...

Eheh it's me that started that thread and i think that guy really did a great job trying to explain what's the problem... now i'm curious to know how many people notices this because till now it seemed that only me and that guy could see this "issue" so sometimes i'm still worried i have a faulty phone...it won't be a good thing since I'm from italy and getting a replacement phone wouldn't be very easy
My screen also appears reddish when i turn off the blacklighting in the clock app :\ maybe its defective?

No, mine experiences the same thing. Seems like reds are more biased when less power is given to the LEDs (not exactly a "backlight"). This is slightly noticeable on the lowest brightness setting too.
And mine experiences the "black line" issue too. I guess it's just how OLED screens work.

ok thanks, it's just reassuring to know that its not only my n1 experiencing this
Seen it slightly a few times. But never bothered me since I'm never in very low brightness that much.

Does it look like this?

[Q] Is it normal to have subtle lines on the screen when viewing at angles?

It doesn't really bother me because I think it's just the way the screen is but if someone else could confirm that would be great.
When you hold your Nexus 7 in portrait mode and angle it so you're looking down or up on it even the slightest bit, you can see subtle horizontal lines. These lines are only invisible if you're looking at it dead/straight on.
Normal? Looks almost like scanlines. If other people have this I'm just going to assume this is the way the screen is manufactured.
That is probably the digitizer for touch sensing

I don't know about that. It actually looks like the edges of specific pixels. I think I've seen the digitizer lines you're referring to, I've seen lines cut into the glass criss-crossing but you only see them when you shine a light on the screen and the line are in the glass. This is not the case here, these lines are on the pixels of the screen and they're visible without shining a light on the screen.
Can you take a picture? As far as I know digitizer looks like very small dot not line.

I don't have a camera that can capture this I think. It's visible with an eye but a camera will just muddle the details of the pixels.
It's really unmistakeable with the eyes. Look at an app icon with the screen dead in front of you in portrait, then tilt the device either a little down or a little up and the app icon will have something that looks like lines running through it. The whole screen should have lines running through it horizontally. Nobody else has that?
EDIT: I think this is why.

Look at the pixel arrangement, those black gaps are what I think I'm seeing. Of course they look huge and black on a microscopic level but with my eye on a macroscopic level they look like subtle lines that are only visible in certain angles. So if this is true, everyone should be seeing these lines when they tilt the screens up and down? Either that or my screen is jacked up.

LG G6 light bleed?

I do! Only on AOD though. Any other black screen I have no bleed at all, but for some reason AOD likes to give off some.

What is AOD btw ?

Got the same bleeding on mine as well
Very common on LCD panel screen. My first two V20 got it, just different corner.

Don't have it there but I have it along the top side of the screen but it doesn't look that bad.
I believe that is just the nature of design. I've read elsewhere that light bleed is almost impossible to avoid 100% with IPS displays.
Sent from my LG-H872 using Tapatalk
Mine doesn't have that but it does have a screen that isn't uniform. The bottom of the screen right above the navigation bar has a warm tint to it making it look sort of yellow compared to the rest of the screen. I'm returning it. I can't look at a screen that isn't uniform. The AOD looks fine though. If the replacement I get has the light bleed on the AOD I'll be returning it.
It's not a light bleed.
It's a special LED only lightning up, when AOD display is enabled.
When seen at 0 LUX your eyes will see it lightning up from bottom. This way the phone won't use the full backlight of the display to only light up at night. It's a side effect from not having AMOLED display.
It is as duckstardeluxe says

I am not sure if this is from the lighting zones on HDR displays, or if LG implemented extra leds at the bottom of the display just for the AOD. Pretty nifty trick to get low light and power consumption on an IPS panel.
The light streak effect that looks like light bleed is due to light falloff as it moves from the bottom LED through the diffuser behind the LCD. So nothing wrong with your displays.
If you want to test light bleed; open a full screen black image in a very dark room. My screen lighting was perfectly even.
mine is exact the same. glad that im not the only one i was ready to send it back lol
Same thing here

Oh, here is why I notice that only with AoD :victory:
What excatly am i looking at ? Do we have what on AoD ? That brighter screen like that ? Yeah when the phone is under some sort of light ( sun, lamps during night ) when in total dark it dims... )

Low Brightness gradient issue

I'm using lux to offer me some of that lo-brightness goodness but I notice that on very dim settings the lighter shades of grey are darker on left side of the screen. Should I be afraid of damaging my screen or is it all good? I'm fine with how it looks but don't want to kill a phone

Mine does the same thing. But the right side is darker than the left. It's a hardware defect. Not bad enough to send it in but it is there. Once you notice you can't stop seeing it. Similar issue with the one plus 2 i had where there were darker lines across the screen. Those were horizontal, this issue with my OnePlus 5 is a vertical band on the right side of the screen.
