The main components of LCD TV include:

Power board, backlight board, main board, logic board, LCD screen.

Extended data:

LCD (liquid crystal display for short) adopts a substance between solid and liquid, an organic compound with regular molecular arrangement, which is heated to a transparent liquid state and cooled to a turbid solid state of crystal particles.

The molecular structure of liquid crystal used in liquid crystal display is similar to a thin matchstick, so it is called nematic liquid crystal, and the liquid crystal display made of this liquid crystal is also called LCD. In LCD TV, a voltage is applied to the liquid crystal between two pieces of glass, and the picture is reproduced through the changes of molecular arrangement and twists and turns. The screen creates a picture through the collision of electron groups, and forms a picture through the perspective reflection of external light.

The first liquid crystal display device in the world was manufactured by Sharp Corporation of Japan in the early 1970s, and it is called TN-LCD (twisted nematic) liquid crystal display.

In 1980s, STN-LCD (super twisted nematic) liquid crystal display appeared, and TFT-LCD (thin film transistor) liquid crystal display technology was developed, but the 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 rapidly.
