Abstract

The invention discloses a display control device which is used for controlling an LED screen. The LED screen comprises a plurality of display lines and a plurality of display rows. The display control device comprises an integrated LED drive device, a central processor and a storage direct access controller, wherein the integrated LED drive device is used for outputting a control signal to the display lines simultaneously, the central processor is connected with the integrated LED drive device and used for configuring the LED drive device according to the LED screen, and the storage direct access controller is connected with the integrated LED drive device and used for directly transmitting display data to the integrated LED drive device.

Description

technical field [0001] The present invention relates to the technical field of display control, and in particular to a display control device. Background technique [0002] Light-emitting diode (LED) dot matrix screens are widely used in indoor and outdoor information display. Due to the large number of pixels and each pixel is controlled individually, it is impossible for the LED controller to directly control a single pixel. The LED controllers currently on the market generally use serial ports to parallel ports to output the information to be displayed to the LED control circuit board through several general-purpose input and output ports. sent to each LED pixel. This process not only needs to output the data to be displayed, but also controls the switching of ranks and columns, which requires the central processing unit (CPU) to participate in the control all the time, and the speed of refreshing the whole screen will be limited, resulting in the inability to realize so...
