In different applications, the pixels of rate of actual requirements can have bigger difference, in general, the LED display is used for video playback, control index requirements within 1/104 is acceptable, also can achieve; If used for simple character information release, control index requirements within 12/104 is reasonable. From what has been discussed above, we can know what rate of pixels is out of control, can appear the cause of the problem and the solution.
