The APD-256G064-1 DC Plasma display offers viewing qualities designers seek such as high contrast, viewing angle of 150 minimum, and long distance readability. It is bright (50 foot lamberts minimum) with characters and graphics figures presented in a pleasing neon orange color against a black background. Plasma is much more readable and eye-pleasing than liquid crystal or vacuum fluorescent displays and is filterable to red, amber, or neutral density.
