    so, are you telling me that after 5 years my LED screen is going to roughly be as bright as it is today?

    Barring other issues related to the thing failing outright, ie, the LED screen actually works as designed for 5 years... it will maintain more or less this brightness and dynamic range?

    Yes. LED's are far superior to cold cathode tubes found in standard laptop/LCD displays. They do not "lose" their brightness unless they are driven too hard in the first place. Not likely as the manufacturers wouldn't of specced the drive current any higher than is necessary when designing the display.

    LED's are an "all or none" component. They do not dim. They will either be working perfectly or be dead as a doornail.

    The LED is your backlight source, I wouldnt worry about that too much, the actual panel is probably going to die or get dead pixels and things first, and if its an OLED panel or something discoloration will happen due to the panel not the backlight source.

    That's right. Man, I love LED-backlit screens...if only the MacBook had it too.

    Well there are more than one LED backlighting the thing isn't there? That means while each individual LED won't get dimmer, if some start to fail early, the overall effect would still be "dimming" wouldn't it?

    Technically speaking, yes, but the thing is that LEDs typically don't fail over time. They usually fail due to spikes in voltage and/or current. Assuming the MBP has a filter to catch those spikes (which it should), the LEDs should theoretically last forever. Theoretically anyway.

    It's most likely that something else on the laptop will mess up before the screen will though.

    so leaving my new MBP up at constant full brightness is ok for extended periods of time?

    i usually sit at about 4 notches from the top, but sometimes its just not that bright, and i want it brighter!

    You just answered your own question, you want it brighter... so turn it up.

    No point in having something and not being happy with it.
