Samsung's new LCD can display independent images on either front or back

When Samsung isn't making rapid advances in the area of memory technology, it's looking for ways to improve display technology. Samsung announced it developed the world's slimmest mobile LCD screen in November. The 0.82 mm thick screen featured a QVGA resolution and a 500:1 contrast ratio. Today, Samsung is showing off the world’s first truly double-sided LCD which can produce independent images on either side of the display.

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.

"Our new double-sided mobile display underscores Samsung's commitment to equip our customers with advanced display technology that accelerates the trend toward slimmer mobile products. We anticipate high demand when we commence mass production in the first half of 2007," said Samsung Executive Vice President Yun Jin-hyuk.

QVGA

I had to look that one up. I thought the Q would stand for Quad (and indeed it does with QXGA and higher) but with QVGA it means Quarter VGA, or 320x240 (240x320 if portrait).

Why don't they simplify things and just state the resolution rather than using all those stupid names like WSXGA?

Generally because its shorter to type QVGA than 640x480.
Oh, and QUXGA is the first Q on the high side IIRC. (2560x1600)
