Abstract
A backlight module comprises a driving backplate, which comprises multiple pads; multiple light-emitting diodes, which are electrically connected to the pads; and multiple transparent protection structures, which are located on the sides of the multiple light-emitting diodes that are away from the driving backplate, wherein the transparent protection structures cover the light-emitting diodes, there is a first distance between the center of the orthographic projection of each transparent protection structure on the driving backplate and the center of the orthographic projection of each light-emitting diode on the driving backplate; and the length of the orthographic projection of each light-emitting diode on the driving backplate is a second distance, the width of the orthographic projection of each light-emitting diode on the driving backplate is a third distance, the ratio of the first distance to the second distance is less than or equal to 1:2-1:10.
