Web12 dec. 2024 · The twisted crystals rotate light waves by 90° as they travel through. Light waves that entered the liquid crystals vibrating horizontally emerge from them vibrating vertically. The vertical polarizing filter in front of the liquid crystals blocks out all light waves except those vibrating vertically. WebA normally white mode Twisted Nematic LCD When the voltage is applied, as it increases, molecules start aligning along the electric field (the dielectric anisotropy of the LC is positive), at a sufficient high field, the 90 degrees twist is removed, and LC layer no longer rotates the light polarization, so at the second polarizer, the light is blocked, and this is …
