I am right now comparing the T400 LED 16:9 with the current MacBook (13") display. The quality and angle-stability is nearly the same, the brightness too. But when you go outside, you dont see anything on your Mac, but the T400 is just great. Glossy Displays are "fail".

Yea, I was debating between a macbook or the t400, but I couldn't get over the glossy screen. My now dead laptop had a glossy screen and not a very bright monitor to begin with, so outside it looked like I had the monitor off :(

@SparkyFlary Not really, LED backlights tent to make the colors look washed out, a decent CCFL display will look better then most low end LED backlit displays.

@protoman1214: Yes. But color desaturation on matte displays only occurs in bright environments, glossy displays are barely readable at all under the same circumstances. In dark environments the desaturation effect of the matte surface is negligible.

Color reproduction pipelines barely use image appearance models, like iCAM06, CIECAM02 etc. It's about white point correction/adaptation and choosing a rendering intent 99.9% of the time. Actual color perception plays only a minor role.

@albedoshader Technically your right, but thats what I meant to say in my post, the actual display panel might be the same, but what you see is greatly affected by whats on top of that display (glossy or matte) so I really was refering the colors your eyes perceive... which is what matters right?

[albedoshader]

@protoman1214: Glossiness is not about color reproduction quality. A glossy screen enhances perceived contrast, that's all. Matte displays always catch a bit of stray light from every direction which can lead to perceived color desaturation. The same effect is visible if you compare glossy to matte paints. Although the color itself might be the same, glossy colors look more saturated. The downside is that glossy screens only look good in rather dark environments.

[protoman1214]

that's true, its all about trade-offs:

glossy=better color reproduction, so better for  movies and photo editing, games etc. but you get glare.

matte=easier on the eyes in normal lit areas, and you can actually see the screen in well lit areas.

I personally prefer the thinkpad screen for my laptop as I wouldn't plan on using a laptop for watching movies and/or photo editing.

Yes. LEDs use less voltage, which ends up in longer battery life. :P

I got the LED backlight in my ThinkPad and the first time I turned the brightness all the way up, it blinded me :D

It's really bright and has a much whiter white, and no yellow/orange tint like my old CCFL laptop.

[SparkyFlary]

the CCFL laptop has a orange like color. is it worth it to get a LED instead?

i have a problem. i have a laptop and since 2 weeks the screen is really dark. i know the problem is the LEDor the CCFL. but how do i know which one to buy. whats the difference. in the video i dont see anything wrong with the computer on the left.
