Abstract
A light-emitting diode (LED) driver configured to generate an LED driving current based on an input signal may include a terminal exposed to outside, a controller configured to identify a first identifier and data from the input signal, identify a second identifier based on a signal applied to the terminal, and when the first identifier and the second identifier are identical to each other, generate a control signal based on the data. The LED driver further may further include a current source configured to generate the LED driving current based on the control signal.
