NEC LCD Technologies, represented by Soanar - Electronic Component & Supply Chain Solutions , have introduced two new TFT LCD modules incorporating white LED backlights for industrial applications. The TFT LCD modules consume less power, are thinner and lighter than comparable LCD modules incorporating cold-cathode fluorescent lamp (CCFL) backlights.
The 10.4-inch module, part number NL10276BC20-12, with extended graphics array (XGA) resolution, and the 8.9 inch 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 durability for industrial use and design optimisation that yield a more than 40% reduction in module thickness. The TFT LCD modules have greater than 50% reduction in weight and approximately 50% 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°C to +70°C, 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. In response to the demand for white LED-based products, NEC LCD Technologies have enhanced their product line-up of TFT LCD modules with eleven industrial-use models that maintain compatibility with conventional CCFL backlight products.
These two new models also meet new customer requirements for sophisticated industrial equipment that include display devices featuring larger screens and higher resolution, in addition to compact size, lighter weight and reduced power consumption (especially on portable terminals and compact measurement instruments).
