The advantages of liquid crystal are small size, low power consumption and no radiation. Disadvantages are also obvious: high price and long reaction time. The fatal wound of liquid crystal is the reaction time. If you want to achieve the display effect of ordinary CRT display, you must have at least 4MS gray scale.

The ordinary 8MS liquid crystal claimed in the market simply can't reach this level. This is related to the parameter measurement standard of liquid crystal performance: the measurement standard of response time declared by the manufacturer is the sum of the time when black turns white and white turns black at the highest voltage (some black-hearted sellers only tell you the uplink or downlink time, so be careful to ask).

The problem is that it is impossible for you to reach this maximum voltage or achieve complete black-and-white conversion under normal use. The most commonly used method is gray scale conversion, which is the meaning of "gray scale".

However, the price of gray LCD is absolutely sky-high. So if LZ is not too rich, it is better to choose CRT. There are many slim CRT models on the market now (especially 17 CRT).
