Extremely Bright Display
The screen on this Toughbook is so bright that it hurts my eyes indoors. I had to turn the brightness setting down to about the halfway mark because it was giving me a headache. The reason for the extreme brightness is so that you can use this machine outdoors, even in direct sunlight. Try looking at the screen on your standard laptop while in direct sunlight and you'll see the difference it makes.
The term 'nit' is a measurement of luminescence. This screen has a 2-1200 nit brightness rating. Most regular laptops have a nit measurement of about 300, and some of the higher grade ones may go up to 500 or 600. Panasonic made this super bright screen go up to 1200, so it literally outshines the competition.
On the model I tested had the touchscreen feature. Part of this requires that a thin protective sheet be layered over the screen to make cleaning easier and to protect the glass. While the touchscreen feature is great, especially with the included stylus, the protective sheet does mess with the display just a little. It's a slightly textured thin layer that causes a sort of sparkly effect when indoors. This is not necessarily a bad thing, but it does play tricks on your eyes a bit.
Widescreen options are not available with the 31 series Toughbooks, so the 4:3 ratio screen may seem a little retro by today's standards. These models all have a 13.1" touchscreen with a native resolution of 1024x768 . Intel and ATI graphic chipsets are available depending on whether or not you need the extra horsepower for 3D applications like CAD.
