A display driver IC and a driving method. The display driver IC is for receiving a system signal to drive a display panel or transmit data to a device. The display driver IC includes an input/output interface circuit, an index register, a control register and a device interface circuit. The input/output interface circuit receives the system signal and then outputs a first address signal and a first data signal accordingly. The index register stores and outputs the first address signal. The control register stores the first data signal and outputs the first data signal according to the first address signal output from the index register. The device interface circuit generates a second data signal according to the first data signal and outputs the second data signal to the device.
