Err, might I ask *why* you need it? What anti-glare filters do is to polarize light that passes through the filter. Since CRTs are emissive, you do not lose as much "light" that is generated by the CRT (unpolarized->polarized), but cuts down on glare considerably (outside source->polarized->bounce off CRT glass->filtered by anti-glare). Since LCDs are non-emissive, it work by polarizing and twisting a source of light (backlight->first polarizing film->color film->crystal->second polarizing film). The crystal determines how much "light" will pass through by "twisting" the light so it either passes through or gets filtered by the second polarizing film. If you are having trouble reading the screen outdoor, that is because the ambient light is overpowering what the LCD provides, similar to how a flashlight is less effective at daylight than it is at night. Reading an LCD is like having a piece of paper that has print on the "back side" of the page and you need to shine a light through in order to read it. "Your" light has to be stronger than the ambient light. Anti-glare will NOT fix that. Either turn up the brightness, or read below for a "cheat". If you have glare "indoors" (true glare - ie, what you would experience with CRT), then the only thing I can recommend is reorient the laptop, or change the angle of the screen. But I have a feeling this isn't what you were referring to. Now, for the cheat. Forget filters. You can improve the readability of your screen with ~$2 or less of parts, and it doesn't have to look half-bad. Get yourself some black heavy-duty construction paper. You need to create an overhang, similar to this: http://www.necmitsubishi.com/products/home/ProductDetail.cfm?product_id=254 This will cut down the side light, and give you more angle where the screen is "viewable" outdoors.
