In TFT LCD displayer,black matrix is used to cover TFT and circuit elements which interfere light penetration.I know that conventional black matrix is on color filter but "integrated black matrix".
Could anyone help me understanding "integrated black matrix"?thanks.
 

I'm not sure it's a true technical device, it's more likely to be sales hype. On aTFT there are discrete light sources with a small gap around them. I think "black matrix" refers to a dark layer painted/printed over the gap between active elements to reduce reflected light and hence improve the potential contrast ratio.
