<p>An LED driving circuit includes: a current generating circuit configured to generate a drive current corresponding to a voltage level of a drive voltage applied to anodes of the first to fourth LEDs so as to alternately drive the first and second LEDs and the third and fourth LEDs; a first drive control circuit connected to cathodes of the first and third LEDs, and configured to drive the first or third LED with the drive current in response to a first control signal for controlling driving of the first or third LED; and a second drive control circuit connected to cathodes of the second and fourth LEDs, and configured to drive the second or fourth LED with the drive current in response to a second control signal for controlling driving of the second or fourth LED.</p> |
