  • Coupling compensation module and light emitting diode driver thereof
    Patent number: 11291095
    Abstract: A coupling compensation module is provided, for compensating a channel voltage of a channel outputted by a constant current circuit of a light emitting diode (LED) driver. The coupling compensation module includes a detecting circuit, for detecting a voltage variation of the channel voltage, to generate a detection result; and a compensation circuit, for compensating the voltage variation of the channel voltage according to the detection result.
