Abstract
A light-emitting diode driver and a display apparatus using the same are provided. The light-emitting diode driver includes a driving module and a plurality of current control modules. The driving module includes a plurality of bias circuits and a plurality of resistive devices, in which any two of the bias circuits are electrically coupled to each other through at least one of the resistive devices. The current control modules are respectively coupled to the bias circuits, and each of the current control modules includes a current control circuit and a slew-rate enhancement circuit. The current control circuit is configured to output a driving current. The slew-rate enhancement circuit is electrically coupled to the current control circuit, so as to output a complementary current.
