Chosen Solution

I replace new glass with digitizer and apply loca glue on the lcd. Probably I put it to much. I cured it in 36W uv lamp 3 times by 4 minutes. After that I assembly it and display looked cloudy. Where I did wrong? Here are the pictures:

You put too much of it and the glue that remains uncured underneath the edges (because uv light doesn’t reach it), found its way to the backlit of the LCD. Th glue stays between the lcd and the backlight panel and produces the cloudy image. Solutions

  1. carefully remove the backlight and clean it with alcohol (ridiculously time-consuming)
  2. buy a backlight panel or find a broken screen of your model phone, remove the backlight, remove your backlight panel too, clean the back of your lcd after removing original backlight very gently with a very soft cloth and alcohol and then install the other backlight on your lcd. NOTE that any debris that stay between the panel and the lcd will produce a dark spot, so make sure everything is crystal clean before installing the new backlight.

I did a replacement last night with the same outcome, if anyone knows the cause of this it would be greatly appreciated. I feel like it’s because the glue hasn’t completely cured out due to not having a proper uv light during the curing process. As far as I know if the LCD was over heated it would turn the screen yellow which isn’t the case in my situation and from what I can tell it’s not the case in the original posters situation either.

Hi. That’s can be pressure marks or when you clean lcd, you was clean up (removing) conductive paint in two corners. This two dots are responsible and works for screen as anti static. Check it properly and if it’s not glue leakage, probably another two problems. Static problem you can sort out with silver paint. The pressure marks are bit difficult to remove, sometimes they disappear itself.
