Chosen Solution
Hi, I’ve started changing the iPhone 6 glass using different equipment (we remove and replace the polarizer too). We are using OCA glue and an autoclave for this activity. How can we avoid losing sensitivity on the touch screen? The screen definitely loses sensitivity after the replacement.
Can be that you dont add the anti-static silver conductive paste (the thin silver line at the top) it can cause issues.
If your screen looks like it has static use the paste http://stsparts.us/products/conductive-p… How are you cleaning your polarizer glue? Make sure the lcd is completely clean before new polarizer application. Another common mistake is to damage the flex on top. Make sure to take polarizer off from top to bottom
I’ve started adding a product called “conductive paste”, applied on the top edge of the screen. Issue solved!
I would say this is something to do with the OCA. I’ve bought polarizers before and they’re never quite just right, some are way too light. I’d ask some suppliers if it would be possible to buy 1 sheet of what they use as a sample. @Rany, I don’t think you have to remove the backlight when using OCA because of how controlled it is. I assume OP uses a machine to automatically slice the polarizer off and then a vacuum laminator to reapply it, either way there’s still no need for any liquids to go near the backlight of the LCD.
I faced the same problem that you faced it’s not about static issues but it’s about lcd thickness and glass and OCA the real problem is before we remove glass it’s working fine right! also after applying Polarizer it’s fine ! also but the problem appear with the two following steps after Vacuum Laminating Machine and After Autoclave most of them after Autoclave for iPhone 6 and 6 Plus I did about 40 - 50 LCD’s all same issue so there must be something wrong !!! I found the problem but don’t know how to fix it the problem is again it’s about the lcd and touch contains from layers vertical and horizontal not visible for human eye so after the pressure the edges of the lcd under the glass it curve so the touch will not be responsive for sure ! but you can still get touch sensitivity if you press hard on glass it will respond so please if any one got an idea how to fix share us please we paid large amount of money and of course we don’t want to lose our friends and customers I used anti static pen same problem I used LOCA no problem !!! 100 % working so please we need a solution for OCA iPhone 6 and 6 Plus LCD’s thanks a lot
Have you tried lowering the mpa on the laminating machine ?
After many test and fails right now all is working fine after I am using oem “mitsubishi” oca sticker. Also adding conductive paste on all screens. And I have not had that issue anymore
I’m getting bubbles under the polarizer film after using the built in pump laminator. It was working fine go awhile then all of a sudden I’m getting bubbles in the Same place. Anyone have the same issues?
Hello, this post will help you a lot: How to solve iPhone 6 Touch Screen Problem
the problem is about polarizer and oca they should be original otherwise you will have problems I’m working on LCD repair for 9 months and this is the problem moreover if they are high quality you will face bubbles problem Hope this will help.
OFF THIS TOPIC. Been doing great on screen refurbishing but seems like on the iPhone 6S once i place on “KO” lamination machine - the screen has lots of Big bubbles. I have done thousand of iphone 6 & 6 Plus but i can’t get it right on the 6S. Any suggestions on this? Thank you
I have the same problem. Please check this video: https://www.youtube.com/watch?v=DVMsZH0D… At the top of screen is oca for iphone 6 and bottom of the screen is oca for iPhone 5. Do you have any experience with defective oca glue ? Unfortunately I don’t have another pack of oca for iphone 6 so I can’t test it. Is the oca for iPhone 6 defective ?
Hi, I have a similar issue and I hope someone can enlighten me on this matter. https://youtu.be/GuPwaGTbS3s So basically my problem is that when I need to remove and replace the polarizer film on the iPhone 6 (mainly), the screen starts to get purple when and where you touch it… I use copy polarizer films, but I do add the silver conductive paste at the top (I also use OCA and 5 in 1 vauum laminator machine). The problem appears once every 5 to 10 screens maybe, but it is very annoying and no matter how many times I redo the acreen I can’t seem to find a way to get rid of it. Any suggestions, is it poor quality polarizer film or something else? Thanks
I’ve the same issue, but i can’t solve the problem. I think it’s the copy polarizer, but i don’t know where i can buy good quality polarizers.
