Claim 11:
12. A method of manufacturing the mini light-emitting diode (mini-LED) backlight module, comprising following steps:
providing a flexible substrate, defining the flexible substrate into a plurality of backlight partitions, wherein each of the backlight partitions comprises at least one backlight sub-region;
forming a first metal pattern on the flexible substrate, wherein the first metal pattern is defined into a plurality of first sub-metal patterns, and each of the first sub-metal patterns is arranged corresponding to one of the backlight partitions; and,
mounting a plurality of mini-LEDs correspondingly on the flexible substrate, wherein the mini-LEDs positioned on each of the at least one backlight sub-region are arranged in an array;
wherein in each of the backlight sub-region, all of the mini-LEDs positioned in a same row are connected in series to form a series branch, multiple series branches are connected in parallel to form a parallel module, and a plurality of the parallel modules are electrically connected through the first sub-metal patterns to enable an external input signal to be input to each of the mini-LEDs in the backlight sub-regions through each of the first sub-metal patterns.
