Abstract: A backlight module and a driving method therefor, and a display panel and a display apparatus. The backlight module includes: a backlight panel; and a backlight driving circuit, which is used for responding to a first timing signal, so as to output a first brightness signal to drive the backlight panel to emit light, and is used for responding to a second timing signal to output a second brightness signal to drive the backlight panel to emit light. For a frame picture of a first sequence frame, a first brightness signal is output to drive a backlight panel to emit light, and for a frame picture of a second sequence frame, a second brightness signal is output to drive the backlight panel to emit light.

Abstract: A driver circuit includes a logic control component and a plurality of pins coupled to the logic control component. The plurality of pins include a clock pin, a data pin and at least two output pins. The clock pin is configured to receive a clock signal. The data pin is configured to receive, under control of the logic control component, a data signal in a period of an active level of the clock signal. The logic control component is configured to generate a driving control signal corresponding to each output pin according to the data signal, so as to control an electrical signal flowing through the output pin.
