Backlight module and manufacturing method therefor, and display apparatus

A backlight module comprising:

• a driving backplate comprising a plurality of pads;
• a plurality of light-emitting diodes electrically connected with the pads;
• a plurality of transparent protection structures located at a side of the plurality of light-emitting diodes facing away from the driving backplate, wherein the transparent protection structures cover the light-emitting diodes, and a first distance is provided between a geometric center of an orthographic projection of a transparent protection structure on the driving backplate and a geometric center of an orthographic projection of a light-emitting diode on the driving backplate, a length of the orthographic projection of the light-emitting diode on the driving backplate is a second distance, a width of the orthographic projection of the light-emitting diode on the driving backplate is a third distance, a ratio of the first distance to the second distance is less than or equal to 1:2, and a ratio of the first distance to the third distance is less than or equal to 1:2;
• wherein surfaces of the transparent protection structure comprises a curved surface and a plurality of side surfaces, the plurality of side surfaces extend in a direction perpendicular to a plane where the driving backplate is located.
