Abstract: The present invention provides a backlight unit and a control method thereof, and a liquid crystal display device. The control method includes steps as follows: obtaining backlight data corresponding to each partition, wherein the backlight data comprises a plurality of bits of data; dividing the light-emitting unit of each partition into a plurality of subfields with different durations in a light-emitting process during a frame, wherein each subfield corresponds to one bit of data, and any two subfields comprise different numbers of secondary subfields; and outputting the plurality of subfields in a preset order.

Abstract: A backlight module and a display device are provided. The backlight module includes a backlight and a driving circuit for driving the backlight. In the driving circuit corresponding to at least one backlight unit in the backlight, a data signal input module is configured for inputting a first data signal to a first point during a detection stage, and inputting a compensated second data signal to the first point according to a threshold voltage detected by a detection module during a display stage. The present invention improves uniformity of light emission of the backlight module.

Abstract: The present disclosure provides a data encoding method, a decoding method, a related device, and a storage medium. The data encoding method first passes a first bit stream of an original encoded data through a logical operation to obtain a second bit stream. Then, through signal determination, negating processing, and insertion of corresponding flag bit, encoded data having a certain jump amplitude is obtained. A problem that signal is prone to error in transmission process is solved, reliability of coding is improved, and signal transmission is facilitated.
