Driver circuit and driving method therefor, array substrate, and display device

Provided are a driver circuit and a driving method therefor, an array substrate, and a display device, relating to the technical field of display. The driver circuit comprises a logic control module, a data pin, and at least two output pins. The data pin is used for receiving driving data. The logic control module is configured to generate, according to the driving data, driving control signals in one-to-one correspondence to the output pins, the driving control signals being used for controlling a current flowing through the corresponding output pin. According to the provided driver circuit, the number of driver circuits in the array substrate can be reduced.
