I was wondering if all LCDs have A/G b4 i start using the A/G Removal technique on my screen. I have tried shining a torch through the screen but seems not much of the light is going through. Is this because there is A/G?

As i understand it; Anti-glare is common on most screens. However the new generation of screens (True Bright and other names thereof) are shiny and do not have an anti-glare layer. Perhaps the specs of the screen or a picture might help.

Not sure what make the screen is, taken it apart now and dont have the casing. I know it's one of them budget screens, very cheap and unknown make. Im gona try the A/G stripping on it and see if there is A/G. Im sure there is. Thanks

You actually don't have to take apart an LCD panel in order to see if it has antiglare or not. Just look at the front of the panel and if you can see the clear, sharp reflection of a ceiling light or desk lamp than it does not have A/G. If the reflection looks fuzzy, hazy then there is A/G. I aslo suggest you search more on how panels are generally designed or at least look up some of the topics here in LL to give you an idea before diving into a exploritory strip of your own.

It should also be noted that LCD screen generall pass between 4 and 9% of the light that hits it, and only that much.

AG does not affect how much light passes through the LCD (or at least not much.) It affects how much the LCD scatters the light that passes through it, which can have an effect on how easy it is to capture that light in the projection lens.
