I never use pure isopropyl alcohol on my screens it can be a bit abusive on some LCD's.. better to cut it down with distilled water before you apply it. I always mix my own in a spray bottle with 50% rubbing alcohol / 50% bottled water ... just to cut the bite of the alcohol down.
Most of the fancy "LCD" cleaner trowels on the market are nothing more than 50/50 water/alcohol solution soaked into lint free napkins.
Just be sure you don't spray directly onto the LCD screen with it since sometimes clumps of water can splotch the screen. Better to spray into a lint free microfiber towel and wipe the screen.
