LCD laptop brightness - CCFL vs. LED
Posted on 2011-03-17
I have a dv9500t laptop with Ultra BrightView display (has 2 CCFL). It really POPS in the sunlight when I crank up the brightness (and it gives me a massive headache indoors if I forget to crank it back down).
Sadly, that is PAST tense... the machine died under extended warranty and HP is replacing it with a newer model.
However, the newer model they suggested only has a BrightView display (not Ultra BrightView). The case manager is telling me that LEDs are "brighter" and so this should be just fine; he also emphasized the more vibrant colors from the LED display as if that has something to do with brightness(?).
The dv9500t BrightView had a brightness of 200 nits or 200cd/m2; I assume that with 2 CCFLs in the Ultra BrightView, that means the Ultra BrightView would be about 400cd/m2 (is that the way this works?)
The dv7 BrightView display has a brightness of 200cd/m2.
My question: is my ability to see in sunlight (i.e. high ambient light environments) solely / primarily a function of the brightness of the display? Will the dv7 LED BrightView at 200cd/m2 be able to come close to the dv9500t Dual CCFL Ultra BrightView display where just ONE of the CCFL puts out 200cd/m2?
