Abstract

The disclosure discloses a Light-Emitting Diode (LED) display, which includes: an LED display panel (10); and a display driving circuit (30), the display driving circuit (30) includes a driving circuit (33) and a control circuit (35), the driving circuit (33) includes a first constant current channel group (331), a second constant current channel group (333) and a third constant current channel group (335), wherein the first constant current channel group (331) controls the display of red lamp tubes of the LED display panel (10); the second constant current channel group (333) controls the display of green lamp tubes of the LED display panel (10); the third constant current channel group (335) controls the display of blue lamp tubes of the LED display panel (10); the control circuit (35) includes a driving control circuit (353), the driving control circuit (353) is configured to control the switching-on or switching-off of the driving circuit (33). The driving circuit (33) and the control circuit (35) are integrated in the display driving circuit (30), and the driving circuit (33) includes the three constant current channel groups which control the ordered display of the LEDs in three primary colors in an LED particle array respectively, so that the effects of small panel area occupied by the control circuit (35), simple design, high refresh rate and low power consumption of the LED display are achieved.
