In addition, since the arrangement of the first flange 32 and the second flange 22 is not affected by the bending radians of the first bending portion 31 and the second bending portion 21, the bending angle of the screen module 1 of the electronic device with the flange structure can be set in the range of 90 ° to 180 ° according to actual needs, and the problem that the electronic device is difficult to assemble with the rear cover when the bending angle of the screen module 1 exceeds 90 ° in the prior art is solved. In addition, the electronic equipment with the bending angle of the screen module 1 smaller than 90 degrees can also adopt the flanging structure, so that the connection area of the connection part of the screen module 1 and the rear cover 2 can be increased, and the connection between the screen module 1 and the rear cover 2 is more stable and reliable.
