Abstract
A mini light-emitting diode (mini-LED) backlight module, a manufacturing method thereof, and a display panel are provided. A plurality of backlight partitions are defined on a flexible substrate to improve brightness uniformity. A plurality of mini-LEDs arranged in an array in each of the backlight partitions are formed into parallel modules, so that a driving voltage and current of the backlight module can be within an appropriate range. The flexible substrate is further arranged with a first metal pattern, and signals can be independently input to each of the mini-LEDs through each of first sub-metal patterns, reducing metal trace resistance of the backlight module, and further improving brightness uniformity of the backlight module.
