Actually, if the screen lives up to that claim, then it would indeed be of above average brightness - here are some independent lab results that were posted previously by vykr in another thread:Quote:

can you give a sample picture of t60 with some dark background?
Note however, that those above from trippytiger referenced TFT lab results were only for notebooks with 14" TFT panels.
The panels of Thinkpads models with a 14" 4:3 SXGA+ TFT panel are -sadly said- always not this well. For example, below are luminance measurements of 9 dispay regions for a T41p, were the maximal value of 131 cd/cm² is only reached in the center of the display:
The measurements for the 8 brightness settings points of the T41p display resulted to the following values:Code:96,3 cd/cm² 112,0 cd/cm² 104,4 cd/cm²
108,3 cd/cm² 131,0 cd/cm² 108,4 cd/cm²
100,6 cd/cm² 122,0 cd/cm² 109,7 cd/cm²
1: 12,0 cd/cm² 2: 18,8 cd/cm² 3: 25,7 cd/cm² 4: 36,3 cd/cm² 5: 49,0 cd/cm² 6: 67,7 cd/cm² 7: 95,0 cd/cm² 8: 130,8 cd/cm².
In contrast here an R50p with a 15" 1600 x 1200 Pixel (UXGA IPS) FlexView TFT gives for a 9 regions measurement:
...so a max. value of 165,4 cd/m² for the lower right panel region. The overall brightness distribution is 82,5 %.Code:136,5 cd/cm² 144,6 cd/cm² 139,9 cd/cm²
139,9 cd/cm² 153,5 cd/cm² 155,5 cd/cm²
153,9 cd/cm² 149,9 cd/cm² 165,4 cd/cm²
Here are some other Thinkpad models luminance datas from 9 dispay regions measurements (showing the max. on battery and ac power):
Thinkpad T43p (2668-F8G #UC3F8UK), 15" Flexview 1600 x 1200 Pixel (UXGA):

- Average max. luminance on ac power: 111,50 cd/m²
- Average max. luminance on battery power: 112,60 cd/m²
- Brigthness difference between some screen sectors is slightly over 30%.
Thinkpad Z60t (25113BU), 14" 1280 x 768 Pixel (WXGA):
- Average max. luminance on ac power: 114,10 cd/m²
- Average max. luminance on battery power: 55,50 cd/m²
- Brigthness difference between some screen sectors on battery until 53%.
- Brigthness difference between some screen sectors on ac power until 42%.
Thinkpad X41 (2525-6NG US26NUK), 12,1" 1024 x 768 Pixel (XGA):
- Average max. luminance on ac power: 124,20 cd/m²
- Average max. luminance on battery power: 81,30 cd/m²
- Brigthness difference between some screen sectors on battery until 19,5%.
- Brigthness difference between some screen sectors on ac power until 25,8%
And here is instead some comparision data for mostly subnotebooks with 12" TFT panels, but among the list are also notebooks with a 7,2" TFT panel (Libretto U100), 10,6" TFT (Averatec 1000), one with a 13,3" TFT (Sony S4M) and one 14" Wide-TFT notebook (Asus W3400V):

As can be seen the plain business line subs, as the Thinkpad X41, HP nc4200 and Toshiba R200 don't have this luminant panels at all.
VKYR,
Thanks for the info.
Do you have any thoughts on what sort of screen this new X60 "Ultralight" screen will be?
Also do you have any stats for Fujitsu's cristal views screens?
is the panel on your T60 made by LG? if you're not sure, just do a parts lookup here:

@jl123
The X60 "Ultralight" TFT-panel could be either from TMD (Toshiba-Matu****a), Boe Hidys or Samsung, all of them do also offer brighter 12,1" XGA TFT-panels. - So far I haven't seen any specific supplier naming for the Ultralight panel.
Related to the Fujitsu panel, I would need a named Fujitsu-Siemens notebook modelltype where these cristal view panels are ought to be supplied for sure.
@murphyja
Yes, these T60 SXGA+ IPS FlexView panels are LG-Philips panels.
VKYR,
A good example of the cristal view is probably the 6240 13.3, I have been told it is rated at 300 nits. And I must say it really looks a *lot brighter than anything else I've seen at 13 or 12 in.
It's so hard to go back and forth in deciding between something like the fujitsu-which is so flimsy, and the new IBM-which is very well built but which looks like its screen improvement will be barely noticable in brightness! Thats why I still wait for portable ones SX 13.3 which I hear will be the closest comprimise between the two. JL
And by Boe-Hydis themselves. The screen is 6-bit, so it cannot be called Super-IPS.Quote:
