NEC LCD Technologies has introduced four new amorphous-silicon thin-film-transistor liquid crystal display modules incorporating a newly designed LED light source unit into the backlight system. These units offer long operating life: 70,000 hours at room temperature (25 degrees Celsius) and 60,000 hours at high temperature (70 degrees Celsius).

The new products expand NEC LCD Technologies’ already extensive line-up of TFT LCD modules with white LED backlight systems.

Increasing demand for LCD modules featuring low power consumption, smaller dimensions, lighter-weight designs and higher resistance to shock and vibration has prompted the development of LCD modules equipped with white LED backlight systems. White LED backlight systems offer superior performance in power consumption, compact designs as well as greater resistance to shock and vibration as compared to CCFL LCD modules. In addition, white LEDs do not require inverter circuits, which generate high-frequency noise and harmonic currents that generate malfunctions in peripheral devices and hinder precise testing results. White LEDs are completely mercury-free and pose fewer hazards to the environment than CCFLs, which contain trace amounts of mercury.

In response to the growing demand for white LED LCD modules, NEC LCD Technologies has aggressively developed a product lineup featuring white LED backlights beginning with the launch of a 6.5-inch LED LCD module (part number NL10276BC13-01C) in May 2007. In September 2008, the company introduced five new white LED LCD modules designed specifically for industrial applications and featuring NEC’s newly designed long-life (up to 70,000 hours) white LED light source unit. The four new white LED products introduced today further expand NEC’s long-life white LED LCD product offerings.

NEC LCD Technologies will continue to enhance its lineup of LCD modules featuring white LED backlight systems to address the needs of various industrial applications. The company also seeks to broaden the range of environments in which LCD modules can be used and to develop new fields of application.

Two of the new LED LCD modules (part numbers NL10276BC30-34D and NL10276BC20-18) will be showcased at the NEC Group booth at the 12th Embedded System Expo (ESEC) at Tokyo Big Sight in Tokyo, Japan, May 13-15, and in the NEC Electronics America booth (#459) at the Society of Information Display (SID) Display Week 2009 at the Henry B. Gonzalez Convention Center in San Antonio, Texas, June 2-4.
