The difference between computer monitor and TV set

Hello everyone ~ I believe everyone will have a doubt, in fact, I also have it. Watching the same thing, TV is generally larger than the display screen used on the computer and has more functions than the monitor. So let's talk about the difference between the two today.

First, the function is different:

1, TV: TV is mainly used to receive programs and has the function of watching.

2. Computer monitor: The computer monitor is mainly used to receive the signal of the computer host, display the signal on the display screen, and then convert it into image content.

Second, the structure is different:

1, TV: TV is mainly composed of tuner, audio head, audio channel, common channel, synchronous scanning channel, color control display and power supply.

2. Computer monitor: The computer monitor is mainly composed of LCD module, control panel and inverter.

Third, the scanning frequency is different.

1, 50 Hz TV.

2. The computer monitor is above 60 Hz.

Extended data:

The signal received by the TV set from the antenna passes through the tuner to select the high-frequency TV signal, and after amplification, it sends out a fixed intermediate-frequency TV signal. After the video is amplified, the image signal is sent to the cathode emitting electrons in the picture tube to control the aggravation of the electron beam emitted by the picture tube, and the image can be displayed on the screen.

The video amplifier circuit of computer monitor can be divided into two parts: preview and video output. The preview amplifier receives the graphics card from the signal interface. R, G and B primary color video signals are amplified to drive the video amplifier output stage. The output stage of the video amplifier is the power amplifier: the large stage amplifies the video signal sent by the preview amplifier to enough power to drive the cathode of the picture tube and modulate the intensity of the electron beam emitted by the cathode. After the electron beam bombards the screen, the function of electro-optical conversion is completed, and the image can be displayed by scanning.
