To strengthen its presence in the automotive-display market, Sharp Microelectronics of the Americas Inc. has introduced LCD technology for next-generation vehicles and an 8.8in. LCD for telematic systems.
The LCD technology, called Advanced Super View (ASV), promises wider viewing angles, higher contrast, and faster response time for next-generation navigation, telematic, and dashboard instrumentation systems, said Joel Pollack, vice president of the displays business unit at Sharp Microelectronics in Camas, Wash.
Automotive applications account for roughly 10% of Sharp Microelectronics' LCD revenue and 3% of global display sales for its parent, Japan's Sharp Corp., he said. While unable to cite exact figures, Pollack expects global automotive-display revenue and unit sales to grow 15% annually.
Sharp's development of automotive-grade ASV technology was made possible by advances in processes, materials, and manufacturing, and overcomes the drawbacks of twisted-nematic LCD automotive displays, according to the company.
An ASV-grade display provides a viewing angle of up to 170 degrees both vertically and horizontally--far wider than twisted-nematic displays, while exhibiting a response time of 25ms or less, compared with 80ms for twisted-nematic, Sharp said. The display has full-motion video capability, and its high aperture ratio eliminates bright-pixel defects.
Pollack said Sharp is bidding on design-in programs with automotive-systems integrators and plans to mass-produce the ASV displays in 2005.
The company's 8.8in. LCD, the LQ088H9DR01, is based on its thin-film-transistor technology and aims at current telematic systems.
The LCD has a pixel resolution of 640 x 480, consumes less than 9.7W, and provides a viewing angle of 85 degrees vertical x 100 degrees horizontal. It can be read in sunlight and has a self-heating backlight.
The display, now available, will be built at a Sharp plant in Japan.
