 Currently widely used LCD is an abbreviation of 'Liquid Crystal Display', which means liquid crystal displays. Here, the liquid crystal is a polymer organic compound that can change into a liquid or a solid depending on external conditions.

Initially, TN LCDs were developed that became the basis of the LCD monitors we currently use.

The TN LCD basically obtains a contrast ratio according to the alignment state of liquid crystals, that is, whether light passes through the liquid crystal.

These TN LCDs are mainly used for the information on the departure time of the airplane at the airport, the guide for the boarding gate, and the large billboard of the roadside.
