What does the big butt monitor mean?

Big butt monitor refers to CRT monitor. The scientific name "cathode ray tube" is a display using cathode ray tube.

CRT displays display images by exciting phosphors on the inner surface of the screen with electron beams. Because the phosphor will go out soon after it is lit, the electron gun must continuously excite these points.

Extended data

CRT display is a kind of display using cathode ray tube, which is usually one of the standard equipment of computer. Early CRT monitors had only a small piece of green, but now 20-inch CRT monitors are very common. With the increase of size, the display effect of CRT display is also improving.

CRT monitors, like other hardware devices, often break down. However, the investigation found that only about 20% of the faults were caused by poor quality or natural damage, and most of the faults were caused by poor environmental conditions and improper operation or management. It can be seen that environmental conditions and human factors are the main causes of display failure.

CRT display is still used in some special occasions, but in most occasions, it has been replaced by thin, light, low power consumption and low cost liquid crystal display.
