Do RF work with LCD?

This may be a misleading post, sorry if it is, by RF I mean Infrared signals like used on wireless keyboards and light guns, do they work with LCD screens like a PSone screen, so I could play Time Crisis with a light gun on a LCD screen?

Its IR not RF, just for future reference. IR is infared, and RF is radio frequency (sp?). IR require line of site, and RF dosnt. And lastly, IR uses light to send a signal, while RF uses radio waves.

actually, they are both electromagnetic waves. There is kind of a spectrum that changes based on the frequency, starting at radio waves, then infared, then visible light, UV, then microwaves, then x rays, and finally gamma rays. Microwaves may be somewhere else, I forgot exactly where.
