Samsung develops first truly double-sided LCD

Samsung Electronics Co, the world's largest provider of thin-film
transistor, liquid crystal display (TFT-LCD) panels announced that it has
created the first LCD panel that can produce independent images on each side of
a mobile LCD display. Samsung's new double-sided LCD can show two entirely
different pictures or sets of visual data simultaneously on the front and back
of the same screen.

This new development will replace two display panels with one, thereby
reducing overall thickness of mobile products by at least 1mm.

Yun Jin-hyuk, Executive VP- in charge of the Mobile Display Division of the
Samsung Electronics LCD Business, said, “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.”

The breakthrough LCD product makes use of Samsung's new double-gate,
thin-film transistor (TFT) architecture. TFT gates are electronic components
that convert the necessary voltage at the pixel level, which controls the liquid
crystal alignment needed to reproduce on-screen images.

Samsung's new double-sided LCD has two gates that operate each pixel instead
of one, so the screen on the front can display different images than the one on
the back. The double-sided display makes use of Samsung's proprietary
Amorphous Silicon Gate (ASG) technology, which accommodates the increased number
of TFT gates without increasing the size of the driver integrated circuits.

The new Samsung mobile display requires only one backlight, while competitive
double-screen LCDs require two.
