I disagree with that, Ed. CCFL backlighting is prone to hotspots and screen bleed, much more so than any LED screen should be, and especially with age.

Contrary to popular belief, LED backlighting is not superior to cold cathode tube lighting. LED's have their benefits, but superior lighting is not one of them. LED's offer more light for less energy, but they are single spot light sources, so lighting is often uneven. It requires a larger diffuser and more LED's, which negates the space saving and energy saving benefits. Also, the part that is hard on the eyes, is the process in which most LED's are dimmed. PWM. Pulse Width Modulation. Basically, the LED's are flickered on and off to reduce the appearance of their brightness. But some people can actually see this effect. The best way to check for it, is to wave your hand in front of the screen. So, for LED bases displays, they look the best with the screen brightness cranked all the way up. My Fujitsu P1610 has LED lighting, and the dimming circuit is not done with poorly executed PWM, but the inverter makes an annoying high pitched whine when I dim the screen. But I'd rather have the high pitched whine I can only hear when it's in a very quiet room, vs. eye strain inducing PWM. Anyways, glad to hear you like your new 17" Macbook. Are you bringing it to CES? -Ed |
