IPS glow vs backlight bleed

[Dogsparky]

Not an interesting story, but i saw a guy on youtube saying TN panels cant have backlight bleed and that is the only pro they have against ips monitors, but then i thought wait cant all lcd monitors have backlight bleed but just the ips monitors get the IPS glow?

@Dogsparky Not too sure, but AFAIK, my 3-year-old 18.5" Acer S191HQL TN panel has no backlight bleed, dead pixels or whatsoever. Very satisfied 768p user. ???

Technically there is always backlight bleed unless you use plasma or OLED.

TN panels can have backlight bleed. My own laptop uses a TN panel and it bleeds a very small amount in the top-left corner. I don't think I've ever seen as rampant of bleed in desktop TN panels as I have in both desktop and laptop IPS panels, though. And I know the difference between IPS glow and backlight bleed.

So i am thinking right then, because when i told the guy that tn panels can have backlight bleed too, he said i should go back to whatever school i am attending and take his word as a IT professional, i have seen enough videos of Linus and other monitor problems to know the difference with that.

 

But was thinking that maybe i got it wrong

Both of my TN monitors (now decommissioned) suffer from backlight bleed.

 

My Dell U2515H doesn't (as far as I can tell) but does suffer from inherent IPS glow.

All you have to do is set your monitor to a black background and turn off the lights... You will still be able to see a glowing rectangle in the room where your monitor is, unlike something like an OLED screen... If you do the same thing on an OLED phone it will be completely black and you will not be able to see the phone in a dark room.

 

That is backlight bleed right there. The reason you can see the glow of the monitor in a dark room on a black image is because the light from the backlight is bleeding through the panel. Of course what most people are concerned about is not actually backlight bleed itself, which is present on all LCD monitors without exception, but uneven or excessive backlight bleed, particularly around the edges. However this too can happen on any LCD monitor regardless of panel type, since it has to do with the sealing around the edges of the panel, not the light passing through the panel itself, so the structure of the panel doesn't have any effect on backlight bleeding around the edges.

So that answers my question then, TN panels can have backlight bleed

Thanks for the detailed description u will use that as a reference actually
