Abstract
The present application relates to light-emitting diode (LED) driver circuits, display devices, and display systems. An example LED driver circuit includes: a driver including a plurality of data channels; a controller electrically connected to the driver. The controller is configured to, in response to detecting that data in all the data channels isin a predetermined time period, control all the data channels to be in a closed state. The predetermined time period is determined based on a duration of an external input signal input to the LED driver circuit.
