LCD Panels (stand alone) VS. LCD panels on laptops

[Chadder007]

One laptop panel's I notice that most of them are lighter/brighter at the bottom of the screen ....it is especially noticable when you are viewing a Widescreen DVD with the black bars at the top and bottom. The top of it is very dark of course but at the bottom the black bar is bleeding through of the backlight. Does this happen on many stand alone LCD panels for the desktop? I don't get to see that many stand alone ones.

well, lemme explain that, for a sec, or at least try to say what I think it is.

laptops, because they have to be so thin and flat, have their backlight installed at the bottom of the screen and then use an intricate mirror system to spread the light out all over the screen.

PC LCD monitors have enough space behind the monitor (you'll notice they're also much thicker than laptop displays) so they mount their light(s) (often around 2 or 3) behind the monitor and spread it out, this makes for a more even spread of the light.

And this leads to an overall brighter image on desktop LCD panels.
