Thinkpads Forum

If my German is correct, our friends on the German Thinkpad Forum are discussing changing
the CCFLs into LED Backlights on the x61, T60 and T61 models:

By any chance, did anyone on this forum do this on a T61?
What are the advantages of using an LED Backlight instead of a CCFL?

Regards,

I haven't done any of them, but LED is brighter, has a longer life, and uses less power than CCFL.

The typical advantages one assumes to receive with LED backlights vs. CCFL are:

- increased brightness / contrast
- lower power consumption
- increased reliability / life

Note however, that if the swap out isn't done right or is poorly designed, you could get light "leakage" and/or uneven brightness around the edges of the screen. There is one company that has kits to do this: http://lcdparts.net/XB_Laptop.aspx

I had gotten two LED kits from iccfl.com, I plan on recording a video once I do it. Hopefully by monday I'll have time.
When it comes to the backlight casing, removing the CCFL and inserting the LED is somewhat of a hassle and it may slightly bend the housing a bit. Which shows an uneven lit screen.

You can bend it back, so it won't be ruined.
Takes a few tries to get it right.

One of the biggest advantages in my book is the increased range between minimum and maximum brightness. My primary desktop monitor suffers from that (CCFL): minimum brightness is still way too bright. Successors with LED backlight can be dimmed much further.

In my case:
Dell: 3007WFP-HC; maximum: 391, minimum 110 (cd/m^2) (max = 3.55 * min)
Newer: Dell U3014: maximum 320, minimum 45 (max = 7.11 * min)
