San Francisco, Calif. Toshiba Matsushita Display Technology Co., Ltd. (TMD), a joint venture between Toshiba Corp. and Matsushita Electric Industrial Corp., Ltd., announced the development of the industry's lowest power displays for mobile PCs at the Intel Developer Forum this week. These include the sub-2.5 W, 14.1-inch XGA (1024 x 768 resolution) and 2.7 W, 14.1-inch SXGA+ (1400 x 1050 resolution) thin film transistor (TFT) displays.
These displays are technology presentations and mass production dates have not been finalized. However, TMD said the technology incorporated to make these low power panels has been established at the company. TMD welcomes integrators' comments on its specifications and performance to optimize the displays for mobile PC designs by the time they are introduced into the market.
TMD said that advances in low temperature poly-silicon (LTPS) TFT technology has enabled the company to produce larger-size displays that are designed to be very thin, compact, lightweight and low power.
"Users today are demanding easy to carry, lighter weight and longer battery life mobile PCs," said Sakae Arai, director and chief customer solution officer for TMD, in a statement. "This new prototype sub-2.5W display is an example of how TMD is working to directly address these needs of today's mobile PC users by reducing power consumption of the LCD to help extend battery life."
The Mobile PC Extended Battery Life Working Group (EBL-WG), a group of companies working together to extend the battery life of mobile PCs, developed recommendations for the power consumption of displays in thin and light mobile PCs, which are 3W for 2004, 2.7W for 2005, and 2.5W for 2006.
The new prototype sub-2.5W 14.1-inch XGA display offers a 1024 x 768-pixel resolution and a viewing area of 11.3 x 8.5 inches (287.7 x 216.3 mm). The module dimensions are 11.8 x 8.9 x 0.2 inches maximum (298.5 x 226.5 x 6.0 mm maximum). Power is rated at 2.38 W based on Intel's EBL-WG2 measurement method.
The prototype 2.7W 14.1-inch SXGA+ display offers a 1400 x 1050 pixel resolution and a viewing area of 11.3 x 8.5 inches (287.6 x 216.2 mm). Module dimensions are 11.8 x 8.9 x 0.2 inches maximum (298.5 x 226.5 x 5.5 mm maximum). Typical power consumption of the 14.1-inch SXGA+ displays is in the range of 3.5 to 4.4W.
Both displays use an RGB color filter array to provide up to 64 gray shades per color for a total of 260K colors, and have a built-in, cold cathode fluorescent lamp (CCFL) backlight unit.
