Announcing Expanded Lineup of IPS LCD Modules for Portable Tablet Devices

Hitachi Displays Ltd. (President: Yoshiyuki Imoto, hereafter referred to as Hitachi Displays) has expanded its lineup of liquid crystal display (LCD) modules, utilizing IPS technology for portable tablet devices. With this expansion, our lineup of IPS LCD modules will include 7-inch WSVGA, 7-inch XGA, 8-inch WXGA, and 9-inch WXGA models by September 2011. Hitachi Displays will continue to further strengthen its operations in IPS LCD module for portable tablet devices in the future.

As demand in the tablet devices market continues to expand rapidly, it is expected that units shipped will reach some 93 million units in 2012 (*1) . For use in a wide variety of situations, the displays used in tablet devices are required to have a wide viewing angle, high contrast and minimal color variation, and the IPS LCD is gaining increased attention for satisfying all of these elements. Hitachi Displays utilized our IPS LCD production technology, cultivated over numerous years, to start mass production of IPS LCD modules for portable tablet devices in December 2010. In response to market needs and increased demand for tablet devices, we have now expanded our lineup of IPS LCD modules for portable tablet devices.

What is IPS LCD?

IPS LCD is a TFT liquid crystal technology of the In-Plane-Switching method with behaviors that differ from those of typical TFT liquid crystals of the TN or other methods. The technology was released in 1995 and commercialized in 1996 by Hitachi, Ltd., evolving through Super-IPS to Advanced-Super IPS, IPS-Pro and then to IPS-Pro-Prolleza*. The IPS technology, whereby liquid crystal molecules spin around on a plane parallel to a TFT substrate in the In-Plane-Switching mode where the movement of these molecules is very simple, features a wide viewing angle, excellent color reproducibility, and high response speed in halftone processing.
Hitachi Displays has devised IPS LCD as the optimum technology for the expectations created by the increasing high resolution of images. Its use has expanded to digital single-lens reflex cameras and mobile phones, and has received lavish praise in the industry.
The IPS technology has significantly resolved the viewing angle issues of liquid crystals that had affected the contrast and color tone depending on the viewing angle, and delivers images that are "beautiful, even when viewed from an angle."
"IPS" is a registered trademark of Hitachi Displays, Ltd.

* IPS-Pro-Prollezza is an abbreviation of In-Plane Switching-Provectus-Prollezza. Provectus means "revolution" in Latin, while Prollezza is a word combining Progress and Bellezza (which means "beauty" in Italian).
