FSTN White background, White edge-lit backlight, bottom (or 6:00) viewing angle, Transflective (positive), RoHS Compliant. Available in both 3V or 5V power supply options. This 40×4 has a wide temperature range: -20°Celcius to +70°Celcius which equates to (-4° Fahrenheit to +158° Fahrenheit).

FSTN (Film-compensated Super-twisted Nematic) provides a sharper contrast than STN by adding a film. The cost is approximately 5% higher than STN. FSTN works great for indoor and outdoor applications and is mainly used in graphic displays and higher end products.  The Transflective polarizer is a mixture of Reflective and Transmissive. It provides the ability to read the LCD with or without the backlight on. It will work for all lighting conditions from dark with backlight to direct sunlight which makes it the most common choice. There is no cost difference between Transflective, Transmissive and Reflective.
