Screen refresh frequency is actually a very abstract head, it is a graphic image on the screen by the electron beam hit and light-emitting fluorescence points, because the cathode ray tube in the phosphor by the beam after the light of the time is very short, so the electron beam must constantly hit the phosphor to make it continue to glow. The electron gun starts with the first line in the upper-left corner of the screen, scan from left to right, the first line is scanned and then starts at the far left of the second row to the far right of the second row, until the entire screen is scanned and then starts from the upper-left corner of the screen, which completes a refresh of the screen.
