I see some horizontal lines when the phone's screen is off and see the screen on a very bright light.
Is it the way LCD panels are supposed to be like or any defect?
I already searched the forum and could not find any answer. Please confirm

what you are seeing is the touch screen digitizer.

Ok. So, it's nothing to worry about. Thank you.
Well... If you don't see it, definitely you have a defect!

I just recently had an idea about the terrible viewing angle of the Gtab's screen. the basics of a LCD screen is a sandwich of glass, liquid crystal, electrodes, and more glass. but the most important part is the back-light, it allows you to see what is displayed on the glass. the back-light on most monitors consists of a row of LED lights and many sheets of paper that evenly spread and carry that light.
my thought being what if we replaced the the films and papers behind the glass to distribute the light better.
sorry for the long post but i realized this after watching a tare down video of an LCD screen. also after thinking when i turn my gtab upside down i can see it at most viewing angles (seeing as the LED strip is directly shining from that angle)
would this be possible?
how about finding a way to flip the screen around?

Hmm that still doesn't solve the problem. You still get that weird angle in portrate and I don't think the cables would reach from the other side.
Good thought though.
the viewing angle has nothing to do with the backlight. A stronger backlight would be better for outdoor viewing though.
There is another long thread on the site with most of this info in it.

I'm not saying its the backlight but the distribution of that light that is the problem

Issue with viewing angle are due to the circular polariser in front of the lcd and also to the material used in the capacitive film, I doubt you will get much by playing with the backlight...
That said the spec of the screen are not the worst I have seen, far from it...

I personally have zero issue with the screen. My Dell Mini 9 is the same way and I just view it head on. When I use my Mini9, I angle the screen to it's perpendicular to my view. I do the same with my Gtab.
Would it be better if it had an IPS with RGB LED backlighting? Yes, but it would also be about $400 more to buy.
That being said, I may ask LG for a sample through work, for one of their new IPS screens, just to see what a difference it makes.

I don't have this issue either.
Yes i have seen it.
You need to hold it in direct sunlight and at a slight angle. Dont have a clue what it is though.

That sounds like the sensor points (or whatever they're called) for the touchscreen digitizer.
That would make sense.. it never bothers me as you only see it in direct sunlight and at a stupid angle.
I have never seen it during normal use even in bright light.

Yes that is exactly what I was talking about. The sensors make sense actually, never thought of that. Doesn't bother me either, was just wondering if it was only my screen.
Thanks guys!

Thats the proximity sensor and the light sensor. Cover the sensor with your finger, Screen brightness will change if you have auto brightness enabled.

Reflection under glass
Sent from my LG-P999 using XDA Premium App
Not the oval thing on the top beside the logo, on the actual capacitive screen itself.
I think the dots are just used for the capacitive screen to work. Also, I've noticed that connecting the dots on each line is a horizontal line on each row. I only saw this when putting it next to my lamp thou.

Yes I saw those lines as well! Had to hold it up to a very bright light lol
At the right angle, the reflection from the sun will shot the dots. It's the digitizer, and it looks cool to me. =D
Hi guys, I recently changed the LCD panel on my phone with an OEM replacement. The screen looked fine but just some days ago I noticed that the bottom of the screen just lights up a lot stronger than the rest of the panel.. This is where usually the navigation buttons are. I use an app called Screen Filter, witch is like Dimmer for the PC. The app doesn't affect that lower portion of the screen and I don't know if it was that what caused the damage... So, first, is it a way to fix my screen? Second, is it possible that the app that dims the screen did the damage? Thanks in advance!

My response in the first thread you posted about this:
_MetalHead_ said:
Is it light bleed? Some LCD panels are plagued with it. I had a replacement N5 that just got sent back to Google that had horrible light bleed on the bottom of the screen. It could just be the panel you used and you never noticed it before. An app can't damage the screen like that, as LCD panels are not susceptible to burn in like OLED is.

Hi
I just replaced my screen at my Asus transformer 300 due to broken one, I have replaced 2 screen and at both of them I see a wired phenomena that the screen looks like it have an internal scratches\crack, it happened at both new screens which cause me to think that the problem is not the screen it self.
If some one had that issue or familiar with that, I will be happy to get any idea/help to provide that solution.
P.S I attached a pictures of the new screens after installation and turn on the device.
Appreciate any help.

What did You actually replaced? Was it touch screen (front glass) or display (panel underneath the front glass)? It looks like Your display is broken.

I replaced the front glass only, per your comment, this is the touch screen, what is the display you mean?

Here is how it looks like: front, rear. There is also option to get both as one piece.
Thanks for your fruitful answer, I replaced only the screen that connect to the front side of the display, I will try to replace it, once again, appreciate your effort.

I also should clarify that display is vulnerable to heat and pressure. So be careful with new one. Good luck.
Anyone else notice the lines hidden in the front glass? It's definitely part of the construction and is impossible to see from the light on the lcd. You can see it if you catch glare from a lightbulb and only on the exact spot of the glare.
Just curious, but to me this looks like a ridging pattern to make the glass strong. Has anyone seen this on other phones or this phone?
I noticed the lines too last night.
Yep but its an LCD panel with Sharps edge technology. Otherwords: it is what it is. The screen looks fake once I turn it on.
sometimes I notice the lines from the touch layer in the right lighting on nearly all my devices... is that what your seeing?

I haven't had a device yet where the sensor could not be seen in the correct light.
Even my Nexus 6P shows lines with light at the correct angle.

I believe so. They are definitely inside the glass. I've just never seen them on another phone. Like I said I cant see them unless it's a direct glare hitting it from a lightbulb or something.

That sounds normal. I don't have the device yet, so I'm just going by my own experience on other devices.
While it is much more distinct on this device. It's normal. I can even see it on my pixel XL if I'm looking for it.
