In the CRT era, screen flicker is a common fault, usually caused by insufficient refresh frequency of the display card. Many users do not know what the refresh rate is, plus the system default is 60 Hertz, many users often use a lot of years low refresh rate to understand the CRT screen can not flicker.
To the liquid crystal display era, environmental protection without radiation, and no flicker and othe
It is well known that the LCD (liquid Crystal display) LCD screen used by laptops has many advantages, such as "low power, no radiation, no dizziness" compared with the CRT (cathode ray tube) Cathode ray tube display used by most desktops, And to a large extent to protect the user's eyesight.
But in the display family, LCD
