Abstract

The invention relates to an LED advertising machine control card and an LED advertising machine control system. The control card includes a first data interface group, a first processor (110), and a second processor (120); the first data interface group includes a plurality of data interfaces; the first processor (110) is used for transmitting first play data stored locally by a controller and anasynchronous play instruction to the second processor (120) when receiving the asynchronous play instruction, or transmitting a synchronous play instruction to the second processor (120) when receiving the synchronous play instruction; and the second processor (120) is connected with the first processor (110) and the first data interface group and is used for processing the first play data so as to obtain data to be played when receiving the asynchronous play instruction, and transmitting the data to be played to a receiving card for displaying the data to be played through the plurality of data interfaces of the first data interface group. The control card provided by the invention does not need HDMI interfaces, can be connected with the receiving card directly through the data interfaces; and the cascading of a plurality of stages of control cards can be realized through the data interfaces, so that the costs of the control card can be decreased.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a control card of an LED advertising machine and a control system thereof. Background technique [0002] In recent years, the LED display industry has continued to develop. The price of LED lights decreases at a rate of about 30% every year, which further reduces the price of display screens per unit area; with the development of technology, LED small spacing gradually rises. Currently, the spacing of outdoor LED display screens is generally around P3, while indoor The pitch of the LED display screen can be P2.5 or even smaller. For the display screen per unit area, the resolution and clarity are further improved, which is suitable for close viewing; compared with the LCD display screen, the brightness of the LED display screen, It has high definition and can be viewed clearly at a distance of 50 meters; because the LED light is self-illuminating, it consumes less e...
