NL4864HL11 LTPS TFT LCD from NEC LCD Technologies

NEC LCD Technologies Ltd announced it has begun sample shipment of a new 3.5-inch-diagonal VGA, low temperature poly-silicon (LTPS) TFT LCD module (part number NL4864HL11-01B). The new LCD module is suited to a wide variety of portable devices such as PDAs and personal navigation devices as it features high ambient light that enables improved visibility in indoor/outdoor environments.

This 3.5-inch system-on-glass module is the first product to be manufactured on the LTPS-TFT mass production line at NEC LCD Technologies' Akita plant. Key features include:

? Higher density through integration of peripheral circuitry
Value Integrated TFT-LCD (VIT) technology used to integrate peripheral circuitry on the glass substrate of the LCD module, enables a significant reduction in the glass substrate periphery wiring and the number of connections with external circuits, resulting in four times higher density than that of conventional 3.5-inch QVGA products.

? High luminance and high reflectance ratios, even with high density
The combination of the company's proprietary super-reflective, natural light TFT-LCD technology (SR-NLT) and LTPS technology, which achieves high transmissivity, allows simultaneous realization of 200cd/m? luminance and 10 percent reflective ratio, even with a high density of 200 pixels per inch. Moreover, it achieves a high contrast ratio of 150:1. These factors jointly combine to realize bright and crystal clear display in any kind of ambient light environment.

? Equipped with touch-panel, timing controller and DC-DC converter
With these features, the new module offers a range of benefits to manufacturers of portable information devices, from a reduction in development costs and lead time, to the miniaturization of portable information devices.

"Recently, the market has seen a rapid increase in the upgrading and diversification of functions for portable devices, creating demand for more information display on screens," said Masaaki Hiroshima, product planning department manager at NEC LCD Technologies. "However, increased information display must be achieved in sync with vivid color expression and improved visibility under direct sunlight to truly fulfill customer needs and expand the market. We are confident that our new system-on-glass LCD module will completely fulfill these needs through a combination of our proprietary SR-NLT and Value Integrated TFT-LCD technologies."
