NEC LCD Develops 3.5-Inch New System-on-Glass LCD Module
NEC LCD Technologies, Ltd. today announced the development of a 3.5-inch (8.9cm diagonal), quarter high definition (QHD) system-on-glass (SOG) liquid crystal display module for mobile devices. Successful mass production trials for the new low temperature poly-silicon (LTPS) thin-film-transistor color LCD modules 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 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.
The complete specs are here. The new models will be displayed at Inter BEE 2006, being held at Makuhari Messe, Japan, from November 15 – 17.
