Abstract: A backlight module and a driving method thereof are provided. The driving method includes following steps: first obtaining backlight data with N bits of data corresponding to each backlight unit in a current frame; then dividing time required by each backlight unit in the current frame to obtain N subfields with different durations; and finally outputting the N subfields of each backlight unit in a preset order, and controlling a scan line corresponding to the backlight unit to perform at least two scans in a first subfield, and a time interval between adjacent scans is less than a second threshold.

Abstract: The present application provides a backlight module and a display device. The present application converts a display image into control information through a driver board, and can precisely control a mini-LED backlight. The driver board is provided with multiple interfaces for transmitting control signals based on different transmission protocols, so the compatibility of the entire display device is improved. In addition, the driver board can be continuously updated by using programmable devices to meet the needs of users.

Abstract: A timing controller is provided. A data enable signal in a timing control module is regenerated by a signal regenerating module. A number of vertical valid display rows is regenerated as a vertical valid display period. A total charge time of all rows of pixels in each frame can be increased effectively. A horizontal blanking period is changed sequentially in a row-by-row manner, thereby compensating charge effects of rows of pixels accurately.

Abstract: A control method of a time sequential control signal and a driving circuit are provided. A main TCON chip and an assist TCON chip compute corresponding frame rates according to pixel clock signal frequencies, then call a corresponding table, and transmit the table to a first driving unit and a second driving unit respectively. The first driving unit and the second driving unit respectively perform scanning on rows and columns of pixels to allow complicated dynamic images to be displayed with smooth motions.
