Bonded Touchscreen Removal

[laptopsandspares]

Good Afternoon,

 

I hope this is the right forum for this. I wanted to ask if anyone has experience of removing (un-bonding) the digitiser from a touchscreen laptop/netbook/phone and if so, would you mind sharing how you did it?

 

i've got a HP touchsreen in for repair, its the LCD glass thats broken and I'm pretty sure I can get the rest of the LCD out, but I'm pretty sure the glass covering is bonded to the screen cover/digitzer. I'm guessing I need to heat it but I have two concerns. First that I think the digitzer is plastic which with heat taht gives obvious concerns. The second is that even if I get it out, I'm not sure how to get it bonded back in place? Any solvent experts out there? HP want £300+ for a replacement assembly which is going to be too steep.

 

Thanks in advance

I've never seen fully bonded touchscreens - only around the edges, in which case a very thin blade (I tend to prefer scalpel or very small stanley knife) will often do the job nicely.

If it's fully bonded from edge to center though, I really would suggest giving up and saving up

:D:D I imagine it's only bonded at the edges but the cover is beveled and bends around the edge of the screen makig it difficult to get a blade under there, although I suppose I could pull the brken stuff out and work backwards. In your experience, will the original glue be enough to hold the replacement?

I replaced a digitiser on an ipaq a few years ago. I had to warm up the edges with a hairdryer to soften the glue then split the seal with a scalpel blade. The new one was warmed up which help reactivate the glue.

As above, a little gentle heating won't hurt - hairdryer is therefore ideal

thanks guys, we are just evaluating the risk involved. if we get it wrong, it's an £800+ mistake ofset against a £40 repair gain and I'm not a betting man with odds like that....

 

thanks for your advice

If it is fully bonded on then I wouldn't chance removing it as you'll never get it on again with it remaining completely clear. One of the screens on our cashless catering got broken a while back - it was just the front layer of glass with the touch screen membrane bonded to it that was smashed. We though we could repair it by un-picking the broken glass and then replacing it, but we could not get the bonded touch screen layer to re-bond clearly so in the end we had to get a new screen (£450)
