The main characteristics of the new modules are as follows.
1. White LED backlight system
Incorporating highly luminescent, highly efficient white LEDs in the backlight system eliminates the need for an inverter circuit, reducing power consumption to 1.8 watts with brightness of 400 cd/m2 in the standard model (NL6448BC18-01) and 3.3 watts with brightness of 800 cd/m2 in the high-luminance model (NL6448BC18-01F), while attaining high density of 140 pixels per inch. Compared to conventional cold-cathode fluorescent lamp (CCFL) backlight systems, this latest technology reduces energy consumption by approximately 50 percent.
Since the white LED is face-mounted, the risk of damage to an LCD module due to shock and vibration is small compared to a CCFL with a glass tube structure. In addition, LCD modules with LED backlight systems are thinner, lighter and more reliable than CCFL LCD modules.
2. High levels of visibility
The new modules have wide viewing angles of 160 degrees both horizontally and vertically, a high contrast ratio of 1000:1 and a fast response time of 18 milliseconds. These features enable information to be reproduced on screen quickly, precisely and without visual stress to the user.
3. Wide operating-temperature range
A wide operating temperature range, from –20 to +70 degrees Celsius, guarantees operation even in the most extreme conditions.
Recently, the demand for LCD modules equipped with white LED backlight systems has risen rapidly in various industrial fields. Since most transportable terminals are battery-powered, they require low power consumption and compact, lightweight displays that are durable enough for use in severe environments, such as outdoors or in vehicles. The need for LCD modules with white LED-based backlight systems that can be used in measurement equipment is also increasing, because white LEDs do not require an inverter circuit, which generates high-frequency noise and harmonic current that can hinder precise testing results. NEC LCD Technologies’ new 5.7-inch LCD modules have been developed to meet all of these requirements and more.
NEC LCD Technologies will continue to enhance its lineup of LCD modules featuring white LED-based backlight systems to address the needs of a variety of industrial applications. In addition, the company aims to improve the range of environments where LCD modules can be used through continued performance enhancement of its broad range of LCD modules.
The new LCD module will be showcased in NEC LCD Technologies’ booth #4801 at “FPD International 2008,” which is being held from October 29 to 31 in Pacifico Yokohama, Japan.
