Product Description
LCD Segment Custom Display TN Screen Blue Backlight HT1621 COB Module

Twisted Nematic (TN) Technology:

  • TN LCDs use liquid crystal molecules that are twisted when no voltage is applied. This twist of the liquid crystals helps control the passage of light through the display.
  • When a voltage is applied to the liquid crystals, they untwist, allowing more or less light to pass through depending on the applied voltage. This twist mechanism is what controls the visibility of the pixels or segments on the screen.
  • TN displays typically use polarizers and a backlight to illuminate the liquid crystals, as the crystals themselves do not emit light.

Display Types:

  • TN displays are often used for monochrome or RGB (color) displays, depending on the application.
  • They are typically seen in segment-based displays (e.g., digital clocks, simple readouts) as well as full-screen displays like computer monitors, TV screens, and smartphone
