    You completely confuse the terms electrodes, transistors, and take things out of context (read the sentence before your quote about IPS displays, it clearly means that E-IPS improved from 2 transistors to 1 transistor per pixel).

     

    Furthermore, the picture you posted completely proves my point. What are those black gaps between each chevron (>) looking element? Oh those are electrodes!

     

    I also love how you have moved from your original position that phosphors are part of the LCD structure and responsible for IR.

     

    As bjiibj suggested, I'm going to ignore you now since you obviously have no clue *** you are talking about.

    I am just a troll, is it so hard? Bjiibj, you are the same as hocheung20, zombies, only zombies respond to trolls! But I am a troll who is amazingly fed up with this Samsung thread, this marketing device. It seems that takes a troll trying to provoke posters (through spreading some errors) to look for info, for people to understand how things actually work. It is good that bjiibj/hocheung20, and of course johns1, have brought so much great info to show IR is standard and this thread is mostly about excessive panic...

     

    Now let the troll go...

    Hocheung20/bjiibj, your last reply has an TRUE error, but I am not into it anymore. Good that you are sure that IR is standard for all LCDs... I think it is great!

    Unfortunately,my replacement LG panel used 1 weeks,now IR occurrd.

     

    Apple,can you done the right thing?

     

    Apple must be held responsible for this!

    I received my (2nd) replacement Macbook Pro with Retina Display on tuesday; initially I had no image retention, but after leaving a checkerboard image up for ~15 min tonight there was image retention on the dark gray background.  I e-mailed the Apple representative I have been working with and will let you know how things go.

    Where are you guys getting the checkboard image?

    To all the owners of an LG panel: could you try this test?


    http://www.mediafire.com/?n09robxfo5j6t17


    This should give a more measurable indication of the retention problem.

    Post your result back please!

    My result code is:

     

    T1401T2536P1G5aB30I0

     

    I have an LG display, rMBP bought July 7 at a local Apple store.  Started noticing image retention after about 3 weeks.

     

    When running your test app (nice app btw!) I let the static checkerboard stay on screen for 4 minutes, then switched to grey and checkerboard was clearly visible.  At about 3:30 on grey the checkerboard was getting very faint but still visible.  At 5:30 the checkerboard was almost nearly gone; it was taking 5 - 10 seconds of looking to find it again after looking away.  It still wasn't 100% completely gone but it was so far gone that I would never have noticed it if I weren't looking for it.

     

    Some small suggestions for your great app:

     

    1. Let the user switch between grey and back to checkerboard with a keypress so that the user can know when to stop (when image retention is visible).  Possibly this is already doable with some combination of keys in the app but I didn't want to disturb my test so I didn't play around too much.

     

    2. Make it easier to copy-paste the result code.  Maybe it was easier than I realized, but I had to manually select the result code and copy it before quitting, if I had forgotten to I don't know how I would have gotten the code back.

     

    EDIT:

     

    Another data point:

     

    Leaving the checkerboard up for 2 minutes also resulted in image retention (not quite as strong as the 4 minute checkerboard image retention, but pretty close) which had faded to nearly completely invisible at 3:30 of grey.  Result code for this: T1200T2232P1G5aB30I0

     

    EDIT:

     

    10 - 15 mnutes after not showing any checkerboard at all, it is still faintly there on a grey background (although it seems to slowly be getting 'overwritten' by image retention of the browser window I am typing this into).

    Here's something really interesting:

     

    EVEN WITH THE BACKLIGHT COMPLETELY OFF, I can still make image retention happen:

     

    1. Ensure that there is no checkerboard image retention currently

    2. Start the image retention test app with checkerboard pattern

    3. Turn off the backlight by using F1 repeatedly until it is off

    4. Wait until the ding (I waited 4 minutes)

    5. Turn the backlight back on

    6. Hey presto, the image retention checkerboard is there in the now grey screen

     

    So obviously the backlight has nothing to do with the image retention, and obviously the pixels are still being held to the values they need to be to display the image, even though the backlight is not on and thus no light is coming through the display, and it is the holding of the pixels at a certain opacity that is resulting in an accumulation of charge that is causing image retention.

    LG is now a major producer of high resolution displays, not budget tier.  They are not anything close to their roots as Goldstar.   They are now producing very cutting edge 4K displays for sale even before Samsung gets their act together.  see  http://www.engadget.com/2012/08/22/lg-4k-84-inch-uhdtv/

     

    IMHO this discussion about LG AH-ISP panels being inferior to Samsung PLS (variant of ISP) offers little proof that the problem is widespread, yes obviously there are some bad panels out there.

     

    As one person observed in Macumors.com: Reading posts on here as well as on Apple forum (over 105 pages) kinda makes your go crazy in thinking that something better is out there, when some say you must exchange until you get samsung and other saying there is no difference.

     

    I ran the 15 min test twice both normal and inverted that RetinaUser supplied, nada IR for my LG based panel (LP154WT1-SJA1).   My laptop is more then couple of weeks old.

     

    They have always been a major producer. That doesn't have anything to do with their quality. Just because they can light the pixels doesn't mean they are the right colors Kia is a major producer of cars - they're still budget tier.

     

    You're quite in denial over this issue and I'm not sure why that would be. Maybe you have an LG and you just don't want to believe that you bought a bad product.

     

    With this many people seeing the issue, and the same people seeing the issue on all 4 LGs they get, it's quite obvious that it's a fundamental product issue. If it was only some, you would have more people saying that their replacement LG is fine. No one has said that. They spot the problem on every new LG until they get a Samsung.

    Good, IR as it was explained/discussed was exclusive to LCD independent of the LED backlight.  Now with you posting this, we can end this turn up brightness all the way aspect of checking for IR.

    Hi bjiibj,

    thank you for your feedback and for the hints.

    I have modified the application and uploaded an updated version, it can be found at the url:

     

        http://www.mediafire.com/?1jwh6o6ql1wmiww

     

    You can now:

    • Temporarily visualize the gray background pressing the key C
    • Copy the result code on the clipboard clicking it
    • Use a new pattern, the RGB chessboard

     

    Let me now explain as the result code is formatted:

     

      T1[Min][Sec]T2[Min][Sec]P[Pattern_Code]G[Gray_Tone]B[Brightness]I[Inversion_Flag]

     

    where the parameters are:

    • T1: the duration of the pattern visualization in minutes and seconds;
    • T2: the time elapsed between the end of the pattern visualization and the test completion (the image retention duration) in minutes and seconds;
    • P: the code of the pattern used for the test. The possible values are the following:
      •   0: No pattern
      •   1: Chessboard
      •   2: Text
      •   3: RGB Chessboard (new version)
    • G: The level of gray in use at the test completion time. It is expressed in hexadecimal notation, between 0 and FF;
    • B: The minimum display brightness level retrieved during the first phase (T1);
    • I: The "inverted mode" flag
      •   0 for normal mode
      •   1 for inverted mode

     

    As an example, your code translates as follows:

         T1401T2536P1G5aB30I0

     

    • T1401: T1 interval (pattern visualization) duration: 4 minutes and 01 seconds;
    • T2536: T2 interval (gray background) duration: 5 minutes and 36 seconds;
    • P1: Pattern used 1 (Chessboard);
    • G5a: Gray tone in use when the test finished 5a (90) ;
    • B30: Minimum Brightness level retrieved during the first phase (pattern visualization), 30;
      •   This indicates that you have not performed the test at full brightness for the entire duration of the pattern visualization (but, as you noticed in your last post, this seems to be irrelevant)
    • I0: Inverted mode 0 (normal mode).

     

    To keep the measures we take comparable between each other I recommend to finish the test only when no trace of image retention is noticeable on the display.

    Well LG and Samsung are both South Korea corporations, and both companines have their positives and negatives.   Just be glad you are not dealing with Samsung customer support for solutions.

     

    I'm in denial, what the heck are you talking about?  I seen IR on laptop displays, even a little on 1 of the 2 MPBr's I owned.  Just because I am discussing not all LG panels has bad IR that I am in denial?   What a argument.

    Here I am again! Brought my rMBP in for repair, got it back with another LG display.

     

    Same day: No IR problem at all

    After 1 day: Nearly imperceptible IR

    After 2 days: Same IR as my previous faulty LG display

     

    Conclusion: It gets worse over time. I'll contact Apple again!
