3.5-Inch VIT System-On-Glass LCD Module with VGA Resolution - NEC

NEC Electronics America introduced a new VGA resolution 3.5-inch low-temperature polysilicon (LTPS) TFT system-on-glass LCD module. This new LCD module combines NEC’s SRNLT and LTPS technologies to achieve high luminance, high contrast, high transmissivity and high pixel density. This display technology enables users to view clear displays in ambient light.

Dr. Shigehiko Satoh,

NEC Electronics America, said:

We have seen a rapid increase in market demand for diverse functionality for portable devices that can display vivid color, even under direct sunlight…

Combining our VIT and SR-NLT technologies, we have created a slim module that meets the visibility requirements of these users…

The new LCD module include value-integrated TFT (VIT) technology, which integrates peripheral circuitry on the glass substrate of the LCD module using LTPS technology. The VIT system-on-glass  LCD module offers high luminance of 200 candelas per square meter (cd/m2) and has a high density of 200 pixels per inch with a reflective ratio of 10 percent. The module is also equipped with a touch panel, a timing controller and a DC/DC converter.

With VIT system-on-glass, NEC achieves a significant reduction in the peripheral wiring of the glass substrate and in the number of connections with external circuits. This results in pixel density that is four times higher than that of conventional 3.5-inch quarter VGA (QVGA) modules, making the new module ideal for a wide variety of portable devices, including personal digital assistants (PDAs) and navigation devices. The VIT technology on the SOG module also significantly improves pixel aperture ratio and backlight efficiency while yielding an overall higher level of balance among attributes.

The new 3.5-inch VIT system-on-glass LCD module will be on display at Society for Information Display (SID) Symposium 2007 in Long Beach, California, May 22-24.
