reaction speed
The time unit for measuring the response speed of industrial displays is milliseconds (ms), which refers to the time required for a pixel to turn from bright to dark and from dark to bright. The smaller the value, the better, and the smaller the value, the faster the response speed of the industrial display. The response speed of mainstream LCDs is above 25ms, and it doesn't matter much in general commercial applications (such as word processing or text processing), because such applications don't need to care too much about the response time of LCDs. And if it is used to play games, watch VCD/DVD and other full-screen high-speed dynamic images, the response time is especially important. If the response time is longer, the screen will have tailings and afterimages. To give a simple example, most LCD monitors on the market will have different degrees of tailing when playing QUAKE3, especially when the screen is updated at a high speed. The CRT does not have this problem at all, because the response time of the CRT is only 1ms, and there is absolutely no tailing phenomenon.
color
When it comes to color, LCD is also inferior to CRT. In theory, the colors displayed by CRT industrial displays are as infinite as televisions. However, LCD can only display about 260,000 colors. Many industrial display manufacturers claim that their products can display 16.77 million colors (16777216 colors, 32 bits), but they are actually implemented by dithering, which is different from real ones. Compared with 32-bit color, there is still a big gap, so it is still inferior to traditional CRT in terms of color expression and transition. For the same reason, LCD is not as good as CRT in terms of expressing gray scale.
