yes, do so
and actually, you can do two - one DSI screen and one FTIR screen, but bear in mind, on FTIR, if you want to have good dragging, you need to make a compiliant surface over the acrylic, which will be not comfortable to touch without some more protections film over it. When I did my first FTIR table, I was using Projector and there was a Rosco Grey projections film on the top, over the silicon compliant layer,for LCD - projections surface is useless..
