Subsequently, the circuit soft boards 42 will pass through the front end 25 in the accommodating space 24, and a part of each circuit soft board 42 passes through the accommodating space 24 and protrudes out of the rear end 26 of the outer frame 2 for a certain distance. In the process of moving the panel assembly 4 down, the circuit soft board 42 is approached toward the lower frame 221 at the same time, so that the back of the panel 41 can be aligned with the front end wall 232 and the front end wall 236. When the back of the panel 41 abuts on the side cladding surfaces 234 of the front end walls 232 and the upper cladding surfaces 238 of the front end wall 236, the panel 41 is placed flat in the accommodating space 24 of the outer frame 2 as shown in FIG. .

Referring to FIG. 15, on the other hand, the backlight module 1 is first rotated into a flat shape so that the optical film unit 14 faces upward. Then, a long jig 62 is pressed on the top of the back frame 11 and the front end of the optical film unit 14 so that the jig 62 blocks the front end of the optical film unit 14. After that, the backlight module 1 is rotated and stood up to perform the inspection operation. The front end of the optical film unit 14 is blocked by the jig 62 to prevent the optical film unit 14 from tilting forward and detaching from the back frame 11. After the inspection operation is completed, the backlight module 1 is rotated to restore it to a flat shape, and the jig 62 can be moved away from the backlight module 1.

Referring to Fig. 16, the step S3 of assembling the outer frame and the panel assembly includes the following sub-steps: pre-positioning step S31, turning the panel step S32, and combining the outer frame step S33.
