x230 IPS screen has white "glow patches" on bottom bezel

I discovered about 4 or 5 "glow patches" which were white and at the bottom of the screen. Each one was about an inch wide and about half an inch high.

I called Lenovo- one year on site warranty- they replaced the screen the next day (ok- great). Problem is, I have just checked with a dark background and there is now one two-inch x quarter of an inch "glow patch" on the bottom right.

Is this something which happens all the time on the IPS screen for the x220 and x230? I feel a bit of a perfectionist and going back to them to report "it hasnt been fixed properly".....?!!?!

EDIT: I dont have anything against the technician- its easiest to see this when up against a dark background and at night time (when I use my machine the most) - but this is supposed to be a "premium" IPS screen.....

 

Are you noticing backlight bleed? Or pressure spots? Both do seem to be relatively common issues on the X230 and X220 IPS displays. I haven't actually seen the spotting issue in person on my brother's X230, although there is definitely some backlight bleed.

Only resolution seems to be a panel swap, and since you have on-site warranty anyway, you could always tell them the problem still hasn't been fixed and see what they can do about it.

 

Hey,

I couldn't see any example pics of the pressure spot- but it looks exactly like your backlight bleed picture! Before the replacement panel I had 5 evenly spaced out. Now I have 2, one is much longer and "flatter", but its still an issue.

Must admit I am really disappointed with Lenovo. I feel like if the technician replaces it again i'm going to have blacklight bleed elsewhere on the new one.....

 

I had the X230 for a bit and at Windows startup, when the screen was black, you could see big white glows near the bezel, especially at the bottom of the screen. Besides this, I saw nothing wrong with the screen.

 

I used the laptop a fair bit for DVDs and I noticed it very easily then

Thing is, we paid for a "premium" screen- so surely we should get one without issues. There's no point Lenovo constantly making the x-series thinner if they cant get the screen to work properly.

EDIT:

I must be honest my backlight bleed is probably minor- but I wanted a really good screen

 

Ok have worked out what is causing it- its the fact the panel is so flimsy. If I literally move one corner of the panel forward the "backlight bleed" completely changes across the panel.....

 

I wouldn't call X230 "IPS" screen "premium." IPS does not always mean great quality. Besides, it's a $50 upgrade... more like a teaser...

 

Maybe you wouldn't but I'm pretty sure Lenovo still does...

 

And "precision" keyboard? I bet the keyboards most of us love are imprecise!

 

Indeed.

Even when I was playing bass, I didn't like the Precision...:hi2:

Guess I'm just imprecise by nature...

 

Actually in the UK its more like $100 upgrade..... and thats exactly what it is- an upgrade. You still have to add the original cost to the screen..... the non-IPS upgrade cost.

This never happened with the TN panels so why IPS ones?

 

"IPS" does not mean absolutely superior to TN in all aspects, including color reproduction and mechanical construction. "IPS" only refers generally to the technology behind the color dots, and has nothing to do with the overall quality of any particular screen. The only thing one can observe for sure with an IPS-based screen is the wide (vertical) viewing angles -- the other aspects vary, depending on the screen panel design and manufacturing.

On the other hand, an excellent TN screen, such as the AUO B156HW01 V.4 used in the T/W530, can perform beautifully.

 

Unfortunately this is pretty common with IPS screens, even on devices like iPads. My X220 screen replacement has even worse light bleed at the top than my original screen.

Theory I had, not sure how valid it is-is this bleeding created by improper fitting either from the installer or from the surrounding casing?

 

You're on! Pressure points caused by improper fitting.

 

Well that sucks. I didn't think about it until a few months after I got the replacement panel and when I tried playing with the screen's fit inside the housing it didn't seem to make a difference.

Perhaps the period of time it was stuck like that+being carried around and flexed through my usage caused its natural state to have bleeding.

 

This is really not true.

Many TN panels *do* suffer from backlight bleed, regardless of type of backlighting used...

However, the above statement was not meant as an excuse for what appears to be a serious problem with IPS LCDs used on X220/230...
