The working principle of LCD TV universal remote control is as follows:

1. Transmitter: The transmitter part of the remote control sends out infrared light signals through the infrared transmitter. These infrared light signals are wireless signals with specific codes to convey remote control instructions.

2. Remote control command code: When the button on the remote control is pressed, the remote control will generate a specific remote control command code. These codes correspond to the functions on each button and are unique.

3. Transmission: Infrared signals are transmitted in rapid pulses or continuous waveforms. These signals travel through the air and travel some distance before reaching the TV’s infrared receiver.

4. Receiver: The TV has a built-in infrared receiver, which can receive the infrared signal emitted from the remote control.

5. Decoder: The decoder inside the TV will interpret the received infrared signal and convert it into recognizable instructions.

6. Execution: Once the decoder parses the commands from the remote control, the TV will execute the corresponding functions, such as adjusting the volume, changing channels, turning on/off the power, etc. Generally speaking, the working principle of the LCD TV universal remote control is realized through the transmission, reception and decoding of infrared signals. When the user presses the button on the remote control, the transmitter will emit an infrared signal. After the infrared receiver of the TV receives the signal, the decoder decodes it into an executable command, and finally the TV performs the corresponding function according to the command.
