Tokyo, November 13, 2006 --- NEC LCD Technologies, Ltd. today announced the successful development of a 3.5-inch (8.9cm diagonal), quarter high definition (QHD) system-on-glass (SOG) liquid crystal display (LCD) module for mobile devices boasting industry-leading picture quality. Successful mass production trials for the new low temperature poly-silicon (LTPS) thin-film-transistor (TFT) color LCD modules, which are ideal for all kinds of broadcasting equipment such as professional video cameras, began at NEC Akita, Ltd. on October 1.
The new SOG module has been realized by the following:
- Number of pixels is suitable to HD image reproduction
This LCD module boasts a pixel number of QHD (960 x 540) and produces high quality images with resolutions of over 300ppi. - Simultaneous pursuit of a wide color gamut and high luminance
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 astonishingly clear and vivid 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 through integration of peripheral circuitry
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.
Recently, there has been an increase in the adoption of small-sized LCD modules for industrial applications owing to current trends favoring compact devices and portable and handheld instruments, such as professional camcorders. However, it has been difficult for manufacturers to employ conventional LCD modules for mobile devices in industrial and other applications. NEC LCD Technologies’ new SOG LCD has not only succeeded in a downsized model, making it suitable for a range of industrial applications, but also in realizing a superior level of picture quality enabling it to meet the demands of industrial and professional fields.
"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.
