How to disassemble touch screen and LCD of Toshiba Excite 13(AT330)?

Now you can see the photos of screen defeat on Toshiba Tablet AT330, Whether I have booted it or not, the defeat is still there. Someone told me that viscosity failure between both of touch screen and LCD, So it caused the screen defeat. He said they must be separated the both to re-adhesive. I can't think of any way to disassemble it.
