Abstract
The utility model relates to an LED (light emitting diode) display screen, in particular to a novel LED display screen with a CPLD (complex programable logic device) driving circuit. The LED display screen comprises a video outputting device supplying video signals to the LED display screen, a sending card converting the video signals to the video signals that can be indentified by a receiving card, the receiving card receiving the video signals of the sending card, and an LED module which are sequentially connected with each other, wherein a CPLD driving circuit board for improving the refresh frequency of the LED display screen is arranged between the receiving card and the LED module, and consists of the CPLD driving circuit and a singlechip. The LED display screen has the benefits that the CPLD driving circuit board is arranged between the receiving card and the LED module and used for improving the refresh frequency of the LED display screen, thereby adding the functions like hardware point-to-point correction, and further enhancing the display effect of the LED display screen.
