Backlight module and display apparatus

A backlight module, comprising:

• a frame body, defining a cavity therein and having an opening communicated with the cavity;
• a light strip, disposed at the opening of the frame body and detachably connected to the frame body, wherein the light strip comprises a lamp bead that is disposed toward the cavity through the opening;
• a fixation backboard disposed at the opening of the frame body and connected to the frame body, wherein the light strip is detachably connected to the fixation backboard, and the fixation backboard is provided with a first surface and a second surface that are opposite to each other;
• a thermally conductive backboard detachably connected to the first surface of the fixation backboard, wherein the light strip is disposed between the thermally conductive backboard and the fixation backboard;
• and
• a thermal insulation board, disposed at a side of the fixation backboard away from the thermally conductive backboard, and disposed on and connected to the second surface of the fixation backboard;
• wherein the light strip has a plurality of said lamp beads, the frame body has a plurality of said openings, each of the openings corresponds to at least one of the lamp beads, and each of the lamp beads enters the cavity through a corresponding one of the openings.
