The working principle of a LCD panel is based on a combination of electrostatic forces, liquid crystals, and polarized light and filter layers. The display is composed of two sheets of polarized glass plates, which are placed between a voltage source and a current source. The electric current passes through the liquid crystals and is changed into an optical signal when it encounters an electric field. Depending on the voltage applied to the crystals, the liquid crystals then twist, allowing for different levels of light transmission to occur, thus creating different images.

The liquid crystals are then illuminated from the back-light source, which is typically an LED or CCFL lamp. This provides visibility to the characters displayed, creating a bright, backlit display. The display has a wide viewing angle which makes it suitable for viewing from almost any angle, without any loss of clarity or contrast.
