  8. Twisted nematic field effect - Wikipedia

    en.wikipedia.org/wiki/Twisted_nematic_field_effect

    Clock with an early LCD prototype based on the twisted nematic field-effect. The twisted nematic effect (TN-effect) was a major technological breakthrough that made the manufacture of large, thin liquid crystal displays practical and cost competitive. Unlike earlier flat-panel displays, TN-cells did not require a current to flow for operation ...

  9. IPS panel - Wikipedia

    en.wikipedia.org/wiki/IPS_panel

    IPS (in-plane switching) is a screen technology for liquid-crystal displays (LCDs). In IPS, a layer of liquid crystals is sandwiched between two glass surfaces.The liquid crystal molecules are aligned parallel to those surfaces in predetermined directions (in-plane).
