How to clean the PSP screen from behind it?

How do i get dust out of my psp's LCD screen?

• i bought a shiny new psp a few months ago... and sort of forgot about it in a drawer (it was in a protective sleeve though) well, i went to use it yesterday, and the screen had gotten a bit dusty, i wiped it down a bit... it seems in perfect condition for the most part, no scratches, cracks, chips, or burnt out pixels, but.... there are some white specks on the screen. some of which are quite large. upon more careful inspection, somehow bits of dust have gotten themselves lodged under the glass and other layers of the screen. is there any way to get these out? they got in there somehow, so it must be possible to get them out, right? hopefully without taking it apart... but if i must, fine. also, im sure im not the only one having the problem. the dust isn't in the screen itself, right? basically... is there a layer of glass covering the actual lcd screen on a psp, that can be easily separated for cleaning?
