NEC LCD Technology has launched a backlight module with a white LED and a VGA (640 × 480 pixels) LCD panel module. The screen size is 6.5 inches and uses amorphous silicon TFT technology. Compared with the company's original products using cold cathode fluorescent tubes, the brightness is increased by more than 20%, and the power consumption is reduced by more than 40%. The module's depth is about 13% thinner and about 17% lighter than CCFL products. Unlike CCFLs, inverters are not used, so high-frequency noise and higher harmonic currents are also significantly reduced compared to products equipped with CCFLs. Mainly for industrial products such as commercial information terminals and measuring instruments. In May 2007, the company released a 6.5-inch LCD panel module that supports XGA (1024 x 768 pixels) with white LED backlights. Through this VGA product, the company has expanded its product line with white LED backlights.
This VGA product is equipped with "NL6448BC20-21C" which is mainly intended for outdoor use and has a brightness of 800 cd/m2, and "NL6448BC20-21D" which is intended to be used indoors and has a brightness of 550 cd/m2 "NL6448BC20-21D". The contrast ratio is standard 600:1, and the power consumption is 2.5W. In terms of sample price, NL6448BC20-21C is 45,000 yen, and NL6448BC20-21D is 40,000 yen. It will be available from October 1, 2007. Reading era
