Samsung Makes Double Sided LCD
Techtree News Staff, Jan 04, 2007 1550 hrs ISTSamsung Electronics has announced that it has created the first LCD panel that can produce independent images on each side of a mobile LCD display.
Samsung Electronics has announced that it has created the first LCD panel that can produce independent images on each side of a mobile LCD display.
The company said that its new double-sided LCD, unlike other conventional double-sided LCDs that can only show a reverse image of the same video data, can show two entirely different pictures or sets of visual data simultaneously on the front and back of the same screen.
Samsung also said that this new development would replace two display panels with one, thereby reducing overall thickness of mobile products by at least 1mm.
Talking about this new LCD, Yun Jin-Hyuk, Executive Vice President of the Mobile Display Division, 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. Besides, the 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 is also learnt that the new Samsung mobile display requires only one backlight, while competing double-screen LCDs require two. One side of the panel operates in a transmissive mode, while the other operates in a reflective mode. By using a unique reflective design that utilizes the light trapped in the opposing screen's transmissive mode, the reflective mode does not solely rely on external light sources such as the sun.
Moreover, the double-sided, dual image LCD's efficient use of light to display images in both transmissive and reflective modes promotes slimmer, more cost-effective products.
The new double-sided LCD is 2.6mm thick and 2.22-inch 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.
Meanwhile, Samsung will exhibit the new double-sided LCD at the Consumer Electronics Show, which opens in Las Vegas on January 8 this year.
