Samsung Sampling LCD Displays Targeting UMPC and Mobile Internet Device Applications

Posted on: Wednesday, 18 April 2007, 00:00 CDT

Samsung Electronics Co., Ltd., the world's largest provider of thin-film transistor, liquid crystal display (TFT LCD) panels, is sampling 4.8-inch and 7.0-inch WSVGA mobile displays this quarter that specifically target the Ultra Mobile PC (UMPC) and mobile internet device (MID) categories. The products are being exhibited in the Mobile Internet Community exhibition area at the Intel Developers Forum on April 17 and 18.

The 4.8-inch display is well suited for wireless broadband internet and portable navigation systems marketed to consumers. On the other hand, the 7.0-inch panel has been developed for use in vertical UMPC markets targeting children's education, as well as for mobile professionals using a variety of PC applications including e-mail.

Samsung Electronics executive vice president Jin-Hyuk Yun, chief of the mobile display business team (LCD Business Division), said, "This technology breakthrough will enable our customers to develop multiple UMPC and MID devices that can take full advantage of the latest software operating system advancements with displays offering higher resolution, less power consumption and a wider aspect ratio. Using a single-chip packaging solution, we have integrated most of the display electronics, providing greater cost competitiveness and space savings for our customers."

The 4.8-inch display uses Samsung's single-chip display driver that combines source driver, timing controller, level shifter and LVDS receiver. Using Samsung's latest advanced integration techniques, the overall circuit footprint and component count have been reduced more than any other comparably-sized product, while providing a convenient high-resolution path for manufacturers to upgrade from the WSVGA format to WXGA.

Samsung is working closely with Intel Corporation to accelerate market acceptance of UMPC and MID market opportunities as an ultra mobile ecosystem participant, specifically in the field of electronic display reference designs.

"Samsung's mobile display division provides a unique ingredient for UMPC and MID platforms by addressing the need for higher resolution displays with lower power consumption," said Anand Chandrasekher, Intel Corporation Senior Vice President and General Manager of the Ultra Mobility Group. "These displays, combined with Intel's low power processor and chipsets, will enable innovative form factors with great battery life for this emerging category."

Samsung's 4.8-inch model consumes a mere 0.9 watts thanks to the company's low-temperature polysilicon implementation.
