A backlight unit, a control method thereof, and a liquid crystal display device are provided. The control method includes following steps: obtaining backlight data corresponding to each of the partitions, the backlight data including multiple bits of data; dividing a frame of a lighting process of each light-emitting unit of the partitions into a plurality of sub-fields having different durations, wherein each of the sub-fields corresponds to one of the bits of data; and outputting the sub-fields having different durations corresponding to each of the partitions in a preset order.

Backlight unit, control method thereof, and liquid crystal display device

The present invention provides a display device and detection method for impedance of the display device. The display device includes a display panel, a circuit board, and a chip-on-film. The chip-on-film includes pins, and the pins include conducting pins and test pins. The conducting pins are electrically connected to a first detection part of the circuit board, and the test pins are electrically connected to a second detection part of the circuit board. The conducting pins electrically connected to the first detection part are connected to the test pins by test wires.

Display device and detection method for impedance of display device

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.

Backlight module and display device including the same

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.
