-[* icon_note] Ever wonder what a polarizing film does? Join us for ***Science with iFixit*** as we shine some light on the inner workings of an LCD and why they need a polarizing film.
- [* black] To start, the backlight shoots light through a thin layer of liquid crystals. As the light passes through it's reflected at different angles by the crystals' orientation.
- [* black] These angles are what determine the color of the light we see. In order to change the angle (and by extension the color) we apply a voltage across the liquid crystals that causes them to change their orientation.
