A quick question

Thanks for clearing up my doubts, I used to believe that the touch mechanism comes with the LCD display kit when it comes to Nintendo DS touchscreen.

My question is whether it is possible to expose the LCD display kit with touchscreen mechanism underwater without any plastic casing housing the touch mechanism.

Regarding pressurizing the interior of the section, I intend to expose the " touch mechanism " with the LCD display panels outside of my submersible , is it possible in this context?

Thanks in advance
