Do you know what material the "liquid crystal" inside the LCD screen is

The "liquid crystal" inside the LCD screen is one of the three main materials of the LCD screen, and its function is significant. Here is a detailed explanation:

1. Basic concepts of LCD display screens

Liquid crystal as a new physical form. It was discovered by Austrian scientist Friedrich Reinitzer in 1888. When the substance is heated until the crystal melts, it changes into a milky white turbid liquid. Continuing heating, the milky white liquid will become a completely transparent liquid, and this phenomenon also occurs during the cooling process. Observing with a polarizing microscope, it was found that this milky white liquid is different from ordinary liquids and exhibits optical anisotropy, that is, the molecules inside the object have a certain degree of ordered arrangement, which is different from the traditional concepts of solid and liquid, and is defined as liquid crystal.
