How LCD Displays work

Liquid crystal display (LCD) is the most widespread display technology. The application of electric voltage to LCDs changes the alignment of the liquid crystals inside the two glass layers. Thus affecting the amount of polarized light that can be transmitted, which is generated either with a backlight system or using polarising filter films.

Different LCD display types in our portfolio

Different LCD display types are currently in use, the major distinction being between passive and active matrix displays:

  • TN (Twisted Nematic)
  • STN (Super Twisted Nematic)
  • DSTN (Double Super Twisted Nematic)
  • FSTN (Film Super Twisted Nematic)
  • PVA / MVA (Patterned / Multi-Domain Vertical Alignment)
  • IPS (In Plane Switching)

A few other types such as HTN or ASTNare also available. The LCD display types differ mostly with regard to the direction of the glass plates in relation to each other and the arrangement of the electrodes. The optical result are LCDs with different contrast values, wider viewing angles, and a certain viewing direction independence.
