Samsung' newly developed semi-permeable mSWV+ display offers a 160-degree-wide view without compromising clarity and works well outdoors under sunlight even without backlight. You probably know that the backlight of your PDA is responsible for up to 90% of overall battery usage. Telecoms Korea writes:

Samsung Electronics developed a small-medium sized semi-permeable liquid crystal display, using mSWV+ (mobile Super Wide View+) based on PVA (Patterned-ITO Vertical Alignment) [...] While currently available small-medium sized permeable LCD’s realize 250 :1 contrast ratio and view angles of 80 degree for up-and-down and 100 degree for right-and-left, the semi-permeable mSWV+ technology offers 400:1 or higher contrast ratio and 160 degree ultra-wide view angle, preventing gray inversion even when the screen rotates in any direction.

Mass production of new LCD will start in the first half of the next year and is expected to be used first in cell phones and other mobile devices.
