| description | The invention discloses an LED screen display driving method, and belongs to the field of LED display. Dividing an LED screen frame display period into a plurality of sub-periods; according to the position of the current display sub-cycle in the whole display cycle, determining channels with mutually crossed pwm in one row; determining an implementation mode of pwm crossing according to the sub-period gray scale data and the crossing coefficient of the mutually crossed channels; repeatedly scanning the line to the maximum line scanning number, and repeating the two steps until the end of the current sub-cycle; and entering the next sub-period, and repeating the above three steps until the whole frame display period is finished. According to the method provided by the invention, some channels are optimized in each sub-cycle, so that the coupling borne by the channels is reduced; in each display period, all channels participate in cross optimization, and the influence on the whole LED in the whole display perio |
