Anti-Reflective Surface Improves LCD Clarity September 2004 Issue Published Date: September 24, 2004
A new industrial TFT color LCD module has been designed with an anti-reflective surface treatment on the front polarizer to improve high-ambient-light legibility and image clarity. Suited for the company’s 6.5" VGA, 8.4" VGA and 12.1" SVGA TFT LCDs, the anti-reflective surface treatment is effective in varying ambient light conditions, including high brightness and outdoor environments. The anti-reflective coating reduces the surface reflectivity of the LCD panel to about 0.3%. Applications include marine/GPS, outdoor kiosk and point-of-purchase displays, gas pumps, and industrial equipment. The 6.5" LCD has a resolution of 640 x 480 dot pixels, 400 nits luminance, and a 300-to-1 contrast ratio, while the 8.4" model has a luminance of 480 nits and a 500-to-1 contrast ratio. Touting reverse scan capability, the 12.1" SVGA module features 800 x 600 dot pixel resolution, 350 nits luminance, and a contrast ratio of 500-to-1. Pricing ranges from $242 to $441 each in OEM quantities. OPTREX AMERICA INC., Plymouth, MI. (734) 416-8500.
