The Devil's Advocate
Samsung's new LCD can display independent images on either front or back
Only a reverse of the original image data can be displayed on the opposing side with conventional double-sided LCDs. With Samsung's double-gate, TFT design, the LCD features two gates which operate each pixel instead of just one. This is what allows Samsung to produce two independent images. Amorphous Silicon Gate (ASG) technology also allows Samsung to manage the increase in TFT gates without a subsequent increase in driver ICs.
One backlight is shared between the two LCDs. The front LCD is transmissive and the opposing screen is reflective (which allows it to capture some of the light from the main screen). In its current form, Samsung's double-sided LCD is 2.6mm thick with a QVGA resolution. Brightness levels register at 250 nits for the front panel and 100 nits for the back panel.
