As shown in fig. 2, the front frame 100 includes a frame structure surrounded by two first bars 110 and two second bars 120, and a first folded edge 111 and a second folded edge 121 respectively folded from the first bars 110 and the second bars 120; the length of the first barrier 110 is greater than that of the second barrier 120, that is, the first barrier 110 is disposed along the length direction of the display device, the second barrier 120 is disposed along the width direction of the display device, and the first barrier 110 can be bent. In this embodiment, a plurality of first folding edges 111 of the first stop 110 are provided, the first folding edges 111 are provided at intervals along the length direction of the first stop 110, a third folding edge 113 is folded at an interval between two adjacent first folding edges 111, and the third folding edge 113 is fixed to the side wall of the middle frame 200 by a screw by forming a screw hole on the third folding edge 113, so that the first stop 110 and the second stop 120 are correspondingly shielded on the upper surface of the middle frame 200, and the display panel 300 is limited. The second flange 121 may be provided with a screw hole, and the second flange 121 may be fixed to the side wall of the center frame 200 in the width direction by a screw.
Because the folded edge of the first stop strip 110 is a plurality of folded edges arranged at intervals, after the first stop strip 110 is fixed to the side wall of the middle frame 200, the first stop strip can be bent along with the bending of the display panel 300, and the requirement of curved surface deformation is met. In addition, the height of the first folding edge 111 and the second folding edge 121 is preferably greater than the thickness of the middle frame 200, so that the middle frame 200 can be well protected. In order to prevent the second flange 121 from damaging a gate COF (Chip On Film), a second flange 122 is formed by outwardly curling the free end of the second flange 121, and the second flange 121 and the second flange 122 form a U-shaped arc. In order to prevent the first flange 112 from damaging the source COF, the first flange 112 is formed by curling outwards from the free end of the first flange 111, and preferably, the first flange 111 and the first flange 112 also form a U-shaped arc surface.
