What is an LCD TV

Liquid crystal display (LCD), which uses a substance between the solid and liquid, has an organic compound with a regular molecular arrangement, and is heated to a transparent liquid state. After cooling, the turbid solid state of the crystal particles appears. substance.

The liquid crystal molecular structure used for the liquid crystal display is similar to that of a fine match stick, and is called a Nematic liquid crystal. A liquid crystal display manufactured by using such a liquid crystal is also called an LCD (Liquid Crystal Display). In the liquid crystal television, a voltage is applied to the liquid crystal between the two glasses, and the screen is reproduced by molecular arrangement change and zigzag change. The screen is created by the collision of the electron group, and the screen is formed by the perspective reflection of the external light.

The world's first liquid crystal display device was manufactured by Sharp in Japan in the early 1970s and is called the TN-LCD (Twisted Nematic) liquid crystal display.

In the 1980s, STN-LCD (Super Twisted Nematic) liquid crystal displays appeared, and TFT-LCD (Thin Film Transistor) liquid crystal display technology was developed, but liquid crystal technology is still immature and difficult to popularize. From the late 1980s to the early 1990s, Japan mastered the production technology of STN-LCD and TFT-LCD, and the LCD industry began to develop at a high speed.
