OK So i got my used WUXGA today from fleabay, and stripped it about an hour ago. I'm down to the lcd without backlight, but with many unwanted layers. I am now water soaking the brighness enhancer or whatever (first layer on backlight side. Its acting like TAC but it is silvery and somewhat reflective). So my question is, how long to soak? I keep on hearing about people getting the rear films off in much less time than traditional AG removal (like 2 hours). The panel is Samsung LTN154U1-L01. I tried a razor under the layer, and its clear like AG, but is putting up less of a fight than AG with no soaking. Not less enough to go without soaking tho...
Just to let everyone know, i have fully stripped a 15" XGA last year, so i know somewhat what I am doing. Heck, my first project based on a 17" SXGA with thermal damage (only a stripe of the display would work right... Flipping and rotating a window of an avi kinda worked when strapped to an overhead.). I was looking at the display and why it was dim and i saw that a dark layer could be puled off of the lcd (the polar bear). I promptly started pulling, and realised that the pixels no longer showed 1/2 way through the strip! LOL Long time ago, before i had even heard of lumenlab...

The reflective layer on the back side of the LCD that I handled came up in two layers. One was a semi-clear sheet and the other had to be peeled off in strips and was very sticky.

well after two hours the TAC like stuff wouldnt budge. Then i discovered a thinner, silvery layer that was ontop of the layer i tried to pull originally. The silvery layer came up after two hours, prolly should have given it 4 (but its late... so only 2) It was hella sticky and left crap ALL OVER the TAC. It looks like now that i can soak the TAC directly it will go, and the corner where i started is very clean and non sticky. I think Ill let this one go overnight. Wish me luck!

What i have going on looks exactly like post #9 in the first link. That settles my stomach a bit. I have no problem with leaving bear polars (lol polar bears) on both sides. Speaking of which, if i were to get new polars, do they need to go on both sides? My old 15" only has polar on the viewing side.

No, it has two, otherwise it won't be an LCD. The polarization layers aren't there for improving the picture (like the AG), they are a part of the technology and an LCD cannot function without both.

Well i guess i didn't look hard enough. Also, it was a long time ago. Right now i have my lcd clean to the polar on back, soaking the front to see if i have a fused AG/polar.

On my Sharp, I pulled the back two layers off without any soaking at all, the first layer pulled off and left a sticky mess, the 2nd was a little harder to pull off but it came off and left Zero glue. I did have to pull what seemed like fairly hard, starting in a corner going up the side then down the top/bottom and up the other side doing the center last.

Well i got my front AG off. There is definitely some graining, I am curious if it will project. I probably should have soaked longer or with acetone, ended up being like a 16h soak with water and paper towel. The back still lookes really nice though.
