What are the main components of LCD TV circuit?

the power supply is the power supply movie.
the commercial power is converted to 12V LCD TV working voltage.
.
the high voltage board will boost 12V to 1500 ~ 1800V high voltage AC.
it is used to light up the CCFL backlight of panel.
.
the driver board is used to drive and control the TFT of LCD.
it is used to display signals.
it is mainly controlled by panel control logic.
brightness control logic, DC to DC conversion logic, The TV board is the part of receiving and demodulating TV signals.

LCD (liquid crystal display) is used for short.
it uses a substance between solid and liquid, organic compound with regular molecular arrangement, which is heated to present transparent liquid state, The liquid crystal used in liquid crystal display (LCD) is similar to a thin matchstick in molecular structure.
it is called nematic liquid crystal, and the liquid crystal display made of this kind of liquid crystal is also called liquid crystal display (LCD).
the liquid crystal TV is in the liquid crystal between two glasses.
voltage is applied, The first liquid crystal display device in the world was made by sharp in the early 1970s.
it is called TN-LCD.
the first liquid crystal display device in the world was made by sharp in Japan in the early 1970s.
the first liquid crystal display device in the world was made by sharp in the early 1970s
