Why am I getting diagonal lines in my LCD that can only be seen when holding the LCD at an angel?
The lines that you see on the LCD after refurbishing the screens comes after the last step of putting it in the autoclave. So basically what is causing it is the wire that you are using to separate the glass from the LCD is causing micro scratches in the LCD and when you put it in the autoclave it forces air into those micro grooves causing the polarizer to separate from the glass. The good news is if you just set that screen to the side for 24 to 48 hours and then retest it on your testers then 9 times out of 10 they will all be gone. So don't worry about the diagonal lines and just retest your screen the next day and you should be all good to go.
REFURBISHING THE NEW IPHONE X
With news of the latest iPhone X (Apples 10th Anniversary iPhone) coming out we all know by now it's going to use Samsung's OLED technology instead of the older backlight technology that was used in all the older iPhones. What does that mean for those of us who refurbish cracked OEM screens in-house? Well, it's not going to be as bad as you might think. Yes, the replacement screens are going to cost an arm and a leg, firstborn child, you get the point. To refurbish the new iPhone x screen it's going to be just like the Samsung phones. The only new machine you will need is a freeze machine <<< (the machine we have) other than that you can use all the same LCD refurbishing equipment you already use to refurbish the older iPhone screens. You have to see the freeze machines costly price tag as an investment in your business and future proofing your repair business at least until the manufacturers come out with a bendable LCD that can't be broken when dropped or cracked on impact.
