NEC LCD Technologies Adds New LCD Modules
Tokyo; Santa Clara, CA; and Duesseldorf, Germany: May 11, 2009. NEC LCD Technologies, together with its sales and marketing channels in the Americas and Europe, NEC Electronics America Inc. and NEC Electronics (Europe) GmbH, has introduced four new amorphous-silicon thin-film-transistor (TFT) liquid-crystal display (LCD) 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 C) and 60,000 hours at high temperature (70 degrees C). The new products expand NEC LCD TechnologiesÂ’ line-up of TFT LCD modules with white LED backlight systems and include a 15.0-inch XGA LCD unit, 10.4-inch XGA LCD module, and 9.0-inch and 7.0-inch WVGA LCD modules.
According to NEC, 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. In addition, white LEDs do not require inverter circuits, which generate high-frequency noise and harmonic currents that may cause 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.
