Samsung Electronics Co announced today that it has
created the first LCD panel that can produce independent images on each side of
a mobile LCD display.
Samsung’s double-sided LCD can show two entirely different pictures or sets
of visual data simultaneously on the front and back of the same screen. Other
conventional double-sided LCDs can only show a reverse image of the same video
data. This new development will replace two display panels with one, thereby
reducing overall thickness of mobile products by at least 1mm.
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. Driver-ICs typically increase in size when more TFT
gates are used. It will be exhibited at the Consumer Electronics
Show, which opens in Las Vegas on January 8.
