[0028] The technical solution of the present utility model is applied to the assembly of the display screen 1000, the magnetic shielding member 110 is installed in the box 500 of the display screen 1000, the surface of the magnetic shielding member 110 away from the box 500 is provided with a receiving groove 110a, the magnetic member 130 is arranged in the receiving groove 110a, the magnetic member 130 includes an N-pole magnet 131 and an S-pole magnet 133 arranged back to back, the surfaces of the N-pole magnet 131 and the S-pole magnet 133 away from the bottom of the receiving groove 110a form a magnetic attraction surface 140, the magnetic attraction surface 140 magnetically attracts the display module 300 of the display screen 1000, so that the display module 300 is installed in the box 500, thus realizing the assembly of the display screen 1000. According to the magnetic flux characteristics of magnets, the external magnetic flux lines formed by the N-pole magnet 131 and the S-pole magnet 133 come out of the N-pole magnet 131 and enter the S-pole magnet 133. The N-pole magnet 131 and the S-pole magnet 133 are arranged along the radial direction of the receiving groove 110a, so that the external magnetic flux lines formed are distributed along the radial direction of the receiving groove 110a. The display module 300 is magnetically attracted to the surface of the N-pole magnet 131 and the S-pole magnet 133 away from the bottom of the receiving groove 110a. In this way, the direction of the external magnetic flux lines is parallel to the surface of the display screen 1000 assembled by the display module 300, thereby reducing the number of magnetic flux lines passing through the surface of the display screen 1000, weakening the magnetic field on the surface of the display screen 1000, and avoiding the metal dust caused by the magnetic field from being adsorbed on the surface of the display screen 1000.
