Samsung announces the first LCD panel that can produce independent images on each side of a mobile LCD display.

This new display will replace two display panels with one, thereby reducing overall thickness of mobile products by at least 1mm, says Samsung. This is actually not that much. It will be interesting to see the first mobile phone designs that use this double sided display.

The new Samsung mobile display requires only one backlight, while existing double-screen LCDs require two. One side of the panel operates in a transmissive mode, while the other operates in a reflective mode. The new double-sided LCD is 2.6mm thick and 2.22" wide, with QVGA (240 x 320 pixel) resolution, and has brightness values of 250 nits for the front and 100 nits for the rear display.
Samsung will show the double-sided display at the CES 2007.
