The invention discloses a Light-Emitting Diode (LED) display, which includes: an LED display panel (10); and a display driving circuit (3), includes a switching circuit (31) and a control circuit (35), wherein the switching circuit (31) comprises a first switching sub-circuit (311) and a second switching sub-circuit (313); the first switching sub-circuit (311) includes one or more field effect transistors; the second switching sub-circuit (313) includes one or more field effect transistors; the control circuit (35) includes: a power supply control circuit (351), and the power supply control circuit (351) is connected with a third end of the switching circuit (31) through a power supply control port. The switching circuit (31) and the control circuit (35) are integrated in the display driving circuit (30), and the two switching sub-circuits control the power supply of R/G/B LEDs in an LED particle array with M lines and N columns in the LED display panel (10) respectively, so that the effects of small PCB area occupied by the control circuit (35), simple design, high refresh rate and low power consumption of the LED display are achieved. |
