apple on back of macbook screen

[tim100]

my question is about the apple that lights up on the back of the macbook. i was looking at the back of the 17 and 13 and the 13 apple was way brighter. it does not matter to me which is brighter but i wondered why. out of curiosity only anyone know why?

Did you check the brightness setting on the displays?

the brighter you set your screen the brighter the apple logo is, So one of those mbp's might have had a lower brightness set.

same brightness. the one also looks whiter and brighter. its a mystery.

is there anyway to test a screens brightness other than just eyeballing it?

There is a slight difference in brightness: the 13" is actually brighter - if not better - than the 17".
Also, there may be more bleed from the screen to the apple on the 13".

you find the 13 in screen better than the 17, anyone else?

The 13" would be brighter because it has more light concentrated on the same area as compared to the 17" which has a larger surface area.

LEDs don't work that way. (They shine in one direction, the Apple is likely a dedicated set of LEDs, albeit on the same circuit as the backlight)

The 13" would be brighter because it has more light concentrated on the same area as compared to the 17" which has a larger surface area.

LEDs do not work that way either. Larger screens = more LEDs. This is why the cost penalty of LED backlighting gets bigger and bigger as the display gets bigger. (likely, this is the holdup on the 30' ACD)
