FSTN LCD (Film Super Twisted Nematic Liquid Crystal Display) is a specific type of monochrome LCD technology designed for enhanced visibility and readability. Here's an overview:

Features of FSTN LCD:

1. Improved Contrast:

   • FSTN uses a polarizing film layer to counteract the issues of light dispersion common in STN (Super Twisted Nematic) displays.
   • This results in better contrast and reduced ghosting compared to standard STN displays.

1. Wide Viewing Angle:

   • Offers a wider viewing angle, making the display legible from more directions without significant distortion.

1. Monochrome Display:

   • Primarily used for displaying black and white or grayscale content.

1. Low Power Consumption:

   • Ideal for battery-powered devices, as FSTN displays are energy-efficient.

1. Applications:

   • Commonly used in devices like calculators, watches, medical equipment, industrial meters, and other applications requiring clear, low-power displays.

1. Challenges:

   • Slower response time compared to modern TFT or OLED displays.
   • Limited to monochrome or simple grayscale, making it unsuitable for colorful and dynamic graphics.
