Lenovo celebrates the 20th anniversary of the ThinkPad

Lenovo is celebrating the 20th anniversary of the ThinkPad brand with two new products that are aimed at business users. The ThinkPad X1 Carbon is Lenovo's most recent vision for the ultrabook platform while the ThinkPad Tablet 2 is an x86 based touch-enabled device for Windows 8.
 
As its name implies, the ThinkPad X1 Carbon makes extensive use of carbon fiber to enhance strength while still providing a lightweight platform for business travelers (it weighs less than three pounds). The machine packs in a 14" display (1600 x 900), third-generation Intel Core processors, RapidCharge technology (allows the battery to recover up to 80 percent of its capacity within 35 minutes), glass touchpad, and built-in 3G connectivity.
 
The ThinkPad X1 Carbon comes with the usual array of ports including two USB ports (only one of which is USB 3.0), a 4-in-1 media reader, and mini DisplayPort.

“Very few brands are fortunate enough to become an industry icon with loyal fans who are passionate about each generation of ThinkPad products,” said Peter Hortensius, president, Think Product Group, Lenovo. “With that in mind, we’re excited to debut the ThinkPad X1 Carbon, the pinnacle of our ongoing quest to push the boundaries on great design and engineering. It meets the demand for an extremely thin and light laptop with the performance users need to accomplish their professional and business goals.”
 
The ThinkPad X1 Carbon starts at $1,299 and will be available later this month from Lenovo.com.
 
The ThinkPad Tablet 2 is built on the tried-and-true formula of a 10.1" screen (1366x768), 10-hour battery life, and a relatively thin profile (0.39" thick). The tablet will be powered by Intel processors (sorry, ARM) and will come in Wi-Fi, 3G, and 4G LTE models. The ThinkPad Tablet 2 will also be available with a keyboard dock that features Lenovo's redesigned keyboard layout (for better or worse).

The ThinkPad Tablet 2 will be available in October to coincide with the launch of Windows 8. Pricing will be revealed at that time.

But how much does it affect the battery life? A 10 inch display is a 10 inch same surface to light. I dont know why you need much more back lighting, then there is the resolution. I would be surprised if 2D workloads really affect battery life that much. How about how much batter it takes to do alot more scrolling?

Higher resolution affects battery life by:

1. Need stronger backlight to achieve equivalent brightness level of a lower resolution backlight.

2. More pixels = more power draw to iluminate those pixels.

3. As noted above, higher resolutoin results in the CPU/GPU working harder, especially playing games at native resolution.

These three factors are the biggest impact to using a high resolution panel screen.

Aside from #3 (which is actually the least important factor), you didn't really explain it well.

Basically, the thin film transistor and capacitor needed for each pixel is not particularly tranparent, and even the ITO lines absorb a decent amount of light. Finally, there's a minimum space needed between pixel electrodes, so more pixels means more wastage.

Add it all up, and high DPI panels probably only let ~5% of the backlight through even with a white image.

In between the transparent subpixels in an LCD pixel, there's a certain amount of opaque space needed for borders and wire traces. The minimum width of these is pretty much the same regardless of your resolution or display size. This means that on a higher res screen, the transparent subpixels must get smaller while these opaque regions remain the same size. So a greater percentage of the display area is taken up by these opaque regions on a high-res screen.

Consequently you need a brighter backlight on a high-res screen for the screen to have the same brightness as a low-res screen. Or if you use the same backlight for both, the high-res screen will appear dimmer.
