The Difference Between Refresh Rate and Frame Rate in Full-Color LED Displays
While the refresh rate and frame rate of full-color LED displays may seem similar, there are notable differences between the two. Frame rate refers to the speed at which the image changes, whereas refresh rate indicates how frequently the graphics card refreshes its output data. A frame rate of 60Hz means the graphics card generates 60 frames per second, while a refresh rate of 60Hz means the graphics card sends 60 signals per second. Generally, the frame rate should be lower than the refresh rate, with the difference accounting for unused frames. Frame rate affects the smoothness of the image, while refresh rate impacts screen flicker. The human eye perceives anything above 16 frames per second as continuous, a phenomenon known as "persistence of vision." However, once frame rates exceed 75Hz, any improvement in smoothness becomes almost imperceptible. In summary, understanding the distinction between refresh rate and frame rate is crucial for optimizing the visual perfo...
