| description | The invention relates to the technical field of display, and discloses a brightness correction method of a miniature LED backlight plate and a driving device.The method is applied to a main control chip and comprises the steps that whether the brightness difference value between the display brightness value of a display partition and a pre-stored reference brightness value is larger than a preset value or not is determined, and if the brightness difference value is larger than the preset value, the miniature LED backlight plate is started; if yes, target driving chips are determined based on target positions, corresponding to the brightness difference values, of the display partitions on the miniature LED backlight plate, the target positions correspond to the target driving chips one to one, and correction current values corresponding to the brightness difference values are determined based on the corresponding relation between the pre-stored brightness difference values and the correction current values; an |
