HOW IT'S WORK
Liquid crystal material Although it is in liquid form, it is a crystal material in a solid form. These material particles, whose ends are similar to oval cylindrical tubes, are normally aligned in a spiral parallel to each other on top of each other. Molecules that are stationary under normal conditions can be controlled by electrical voltage. Today, TN(Twisted Nematic) mode is the most widely used type in this display technology.
LCD Displays consist essentially of liquid crystal material placed between two transparent glass sheets. The inner surface of the glasses has channels coated with conductive polymer to apply voltage. According to the electrical energy applied to the liquid crystal in these channels, they are aligned in a polarized linear order, or they are aligned from one spiral surface to the other surface. This spiral structure bends the light so that light can be transported between the polarizing filters positioned perpendicular to each other. When electrical energy is applied to them, they curtain the light and create the image (dark black segment) on the LCD by lining them linearly behind each other.
