Planning Is it possible to cut a TFT panel?

    Could you not somehow clamp the screen behind the cut frozen bit to stop the crystals from running?

    Even if you freeze it and some how make the perfect cut, I don't think you'll be able to stop the liquid crystal creeping back into the display over time.

    There are companies out there that offer custom TFTs, but the ones I found (http://www.anders.co.uk/) only supply to industry. :(

    The capillary effect should take care of that well enough. The key here is to find a way to cut it without stressing the panel mechanically.



    Anyway, I'll try to do this again sometime during this week if i find time to do it. (Yes, there will be pictures of the carnage :) )

    ...and keep in mind you can make repeated cuts to the one you've already operated on, just cut off another centimeter each time.

    maybe a water jet cutter would work. other than having to seal it up during the cut this might work.

    I know you can cut glass with the diamond powder dremel cutoff wheels. The bandsaw's downward action seems like it would place more vertical pressure on the screen. Also, less people have access to one, but perhaps the op does. I could see a toothless bandsaw blade as being much quicker but still gentle. SLOW AND STEADY with whatever you use.

    I know the cost would be high, but have you checked to see if any companies will make a custom screen for you?

    Actually he just prove it can be done, just not with a knife. From the looks for the damage most of it was from the pressure, if he'd use a fine tooth saw, 200 count maybe, the damage might be more localized.

    here's another suggestion: How about just steadily sanding away all the unneeded material? You really don't need to make a cut, as the part that comes off is useless anyway...

    Keep the win flowing guys!

    A diamond cutoff wheel would work, I was thinking the usual fiberglass ones that are more interested in exploding then cutting... You'd just have to watch out for overheating with the dremel. The bandsaw could cause it too, but I'd expect it to be less likely with a slow speed compared to the dremel.

    I was going to suggest this as well. Though IDK if what kind of stress this would cause on the internal structures. I have been able to waterjet cut plexiglass, glass, tile, steel, etc. And I have never had to brace it when cutting either just lay it directly on the bed, so maybe that meens the stresses will be low. ;)

    I still think even *IF* you manage to cut it you will most likely have problems down the road with the LC creeping around.

    GL though!

    Have you tried "Ask A Ninja?"

    ... maybe he could do it in one slice :thumb:

    wouldnt the pressure needed to sand the glass down be enough to damage the screen?

    What kepps the material from leaking around now? Are the edges fused? Is there a clamping force? I really don't know much about LCDs other than the theoru of operation and a couple of key pieces like the use of conductive glass and that the crystals need to be oriented correctly before the the sandwich is finished.

    um, am I the only one that read that and it immediately occurred to me that you're suggesting to cut an electronic device with water?

    Surely that's a complete recipe for disaster?

    thinking some more about it, i think the best way to do it would be to clamp the screen down in the place where you want the new bezel to be, and then cut straight along that line with a dremel cutting disk. You absolutely want all the layers to stay together, so you need to eliminate all vertical pressure fluctuations. A dremel disk cuts directly perpendicular to the glass, so that's a good bet.

    Cut the strongest layer of the sandwich first, then turn it over to cut the other side. This makes sure the pressure needed to cut the material presses the layers together, instead of apart. I'd really like to see this done, does it show? :D

    For most electronic stuff as long as its not on and you dry it out before turning it back on there is no problem.

    After thinking of my own idea more water would probably get in between the layers and mess up the LC.

    Oh also water is non conductive in its most pure form. Its the stuff that gets in to water (small particles) that make it conductive.

    Cutting the strongest layer (Glass) first is a bad idea. It's the glass that holds it together, after all.


    Problem is that water used in water jet cutters are mixed with sand.

    Indeed, I stated that in a few posts before, was just a random idea from me.
