NEC LCD Technologies, Ltd. developed a 3.5-inch (8.9cm diagonal), quarter high definition (QHD) system-on-glass (SOG) liquid crystal display (LCD) module for mobile devices.
Successful mass production trials for the new low temperature poly-silicon (LTPS) thin-film-transistor (TFT) color LCD modules, which can be used with all kinds of broadcasting equipment such as professional video cameras, began at NEC Akita, Ltd. on October 1.
The new SOG module boasts a pixel number of QHD (960 x 540) and produces high quality images with resolutions of over 300ppi, making it suitable for reproduction of HD images.
A higher dimensional balance between an ultra-wide color gamut of over 100% for NTSC and high luminance of 350cd/m2 has been achieved by optimizing the back-light system and the color filter based on the high transmissivity of LTPS thin film transistor (TFT) LCD technology, realizing clear color reproduction that has been insufficient in small-sized LCD modules for mobile devices such as mobile phones, PDAs and digital cameras to date.
Downsizing and integration of instrumentation has been achieved by the employment of LTPS that enables a narrower LCD frame than that of amorphous silicon and integration of semiconductor systems on the glass substrate of the TFT LCD enabling a reduction in the number of instrumentation parts built into the new SOG LCD.
"Broadcasting and other industrial fields are demanding small-sized SOG LCDs of superior picture quality. In an effort to meet these needs, we at NEC LCD Technologies continue to strive to enhance our SOG technological competence to enable LCD modules that realize and fulfill all of our customer and market needs. We are certain that our new 3.5-inch SOG LCD will enable expanded application of SOG LCDs in these fields, and we are continuously developing our technology toward the provision of even higher dimensional picture quality." said Masaaki Hiroshima, department manager in charge of product planning and marketing, NEC LCD Technologies, Ltd.
The new models will be displayed at Inter BEE 2006, being held at Makuhari Messe, Japan, from November 15 ? 17.
