NEC Electronics America, Inc. and NEC Electronics (Europe) GmbH, has introduced two new amorphous-silicon thin-film-transistor (TFT) liquid crystal display (LCD) modules incorporating white LED backlights for industrial applications. The modules consume less power, are substantially thinner and lighter than comparable LCD modules incorporating cold-cathode fluorescent lamp (CCFL) backlights.

The 10.4-inch (26 cm-diagonal) module, part number NL10276BC20-12, with extended graphics array (XGA) resolution, and the 8.9-inch (23 cm-diagonal) module, part number NL10260BC19-01D, with wide super-video graphics array (WSVGA), offer numerous benefits over conventional CCFL products. These modules with LED backlights have advantages which include durability for industrial use and design optimization that yield a more than 40 percent reduction in module thickness, greater than 50 percent reduction in weight and approximately 50 percent savings in power consumption compared with CCFL based LCD equivalents. To address the diverse demands of industrial display applications, each model features a wide operating temperature range of -20 to +70 degrees Celsius, a replaceable LED backlight unit and long-term product support.

Recently, the demand for industrial applications using LCD modules equipped with white LED backlight systems has risen due to the systems’ lower power consumption, thinner and lighter-weight backlight housings and higher resistance to shock and vibration compared to CCFL based LCDs. Furthermore, white LEDs do not require an inverter circuit, which generates high-frequency noise and harmonic current that can cause peripheral equipment malfunctions and hinder precise testing results.
