18PIN FPC Connect Custom LCD Display Screen TN Segmented Black Characters

A Segment LCD (Liquid Crystal Display) is a type of display that consists of predefined segments or shapes, such as numbers, letters, icons, or symbols, which can be individually controlled to create specific visuals. These displays are widely used in simple electronic devices where only limited information needs to be shown.

How Segment LCDs Work?

1. Predefined Segments:

   • Each segment is an independent electrode pattern shaped like a numeral, letter, or symbol.
   • Segments are controlled by applying a voltage to their corresponding electrodes.

2. Liquid Crystal Technology:

   • The display uses liquid crystals that twist and align to modulate light.
   • When voltage is applied, the liquid crystals change alignment, altering the passage of light and making the segment visible or invisible.

3. Backlight or Reflective Surface:

   • A backlight (for visibility in low light) or a reflective surface (for natural lighting) enhances segment visibility.
