Thin IPS LCS Module (1.29mm thick) Developed for Mobile Phones
Hitachi Displays, Ltd. (Executive President: Kazuhiro Mori) has developed the world's thinnest, 1.29mm thick, IPS LCD module for mobile phones.
The module thickness of the newly-developed product is half that of existing products. This is achieved by combining an IPS LCD featuring high picture quality and a wide viewing angle with glass (0.2t) and thin-film optical waveguide.
Hitachi Displays has developed various technologies, including high definition (VGA) and low power consumption technologies for its IPS LCDs, with a high picture quality to meet the increasing mobile TV applications and, pursued still more in this development, a thinner module.
Sample shipment of the product is scheduled for November, 2006. The product will be displayed at FPD International 2006, which is being held at Pacifico Yokohama from October 18 to 20.

What is IPS technology? |
IPS technology is a horizontally charging LCD technology that functions differently to conventional TFT LCDs. Hitachi, Ltd. unveiled IPS technology in 1995, and it has been used in commercial applications since 1996, evolving into Super-IPS, Advanced-Super IPS and IPS-Pro. Liquid crystal molecules rotate parallel to the TFT substrate when a charge is applied horizontally. This simple movement of molecules produces superior performance in terms of viewing angle, color reproductivity and response speed to halftones.
IPS technology has been used for large 32-inch LCD television sets manufactured by Hitachi, Ltd. and Matsushita Electrical Industry. The picture quality of these sets is rated very highly.
