Abstract: An LED display device and an LED control system. The display device comprises: an LED display panel (10); a display driver circuit (30) that comprises: a switch circuit (31), a driver circuit (33), and a control circuit (35), where a first terminal of one between the switch circuit (31) and the driver circuit (33) is connected to a power supply terminal of a power supply device, while a first terminal of the other is connected to a ground terminal of the power supply device, and a second terminal of the one between the switch circuit (31) and the driver circuit (33) is connected to an anode of the LED display panel (10), while a second terminal 353 of the other is connected to a cathode of the LED display panel (10); and, a control circuit (35) that comprises: a power supply control circuit (351) and a driver control circuit (353), where the power supply control circuit (351) is connected to a third terminal of the switch circuit (31) via a power supply control port, and the driver control circuit (353) controls the turning on or turning off of the driver circuit (33). The display device integrates the switch circuit (31), the driver circuit (33), and the control circuit (35) into the display driver circuit (30).
