Small-pitch LED display has the characteristics of high refresh, high grayscale, high brightness utilization, no image retention, low power consumption, and low EMI. Even at low brightness, the grayscale performance of the display screen is almost perfect, and the level and vividness of the display screen is higher than that of the traditional display screen, and it can show more image details without loss of information. The number of times that the electron beam repeatedly scans the image on the screen. The higher the number of scans and the higher the refresh rate, the better the stability of the displayed image (picture). The lower the refresh rate, the more flickering and shaking the image, and the faster the eyestrain. Under high refresh rate, the small-pitch LED screen can capture images stably, without ripples and black screens, with clear image edges, and accurately restore the true image information.
