[0024] A display module that prevents the wiring from breaking after the FPC is bent, referring to Figure 1 , including a display screen 10, which includes an upper polarizer 11, an upper glass 12, a lower glass 13 and a lower polarizer 14 arranged in sequence, wherein the size of the lower glass 13 is larger than that of the upper glass 12, and an FPC 20 is bound to the side of the lower glass 13 facing the upper glass 12, and the FPC 20 is bound to the lower glass 13 beyond the range of the upper glass 12.

[0025] Reference Figure 1 and Figure 2 One end of the FPC 20 is bound to the lower glass 13, and the other end of the FPC 20 is bent to the back of the display screen 10, that is, the side of the lower polarizer 14 away from the lower glass 13. The FPC 20 is bent along the thickness direction of the lower glass 13, and the lower end of the lower glass 13 is the bending point of the FPC 20.

[0026] Reference Figure 2 and Figure 3 The lower end of the lower glass 13 is edged relative to the bend of the FPC 20 to prevent the lower end of the lower glass 13 from scratching the wiring of the FPC 20. Two right-angle structures 131 are arranged at the lower end of the lower glass 13. The two right-angle structures 131 are symmetrically arranged, and each right-angle structure 131 consists of two right-angle sides.

[0027] Reference Figure 2 and Figure 3 Each right-angle structure 131 is provided with two grinding corners, which are respectively a first grinding corner 1311 and a second grinding corner 1312. The first grinding corner 1311 and the second grinding corner 1312 are respectively located on two right-angle sides of the right-angle structure 131. The first grinding corner 1311 and the second grinding corner 1312 are two right-angle sides that are respectively indented inward by a certain distance.

[0028] Reference Figure 2 and Figure 3The first grinding angle 1311 is located at the side of the lower glass 13 near the lower end, and the second grinding angle 1312 is located at the lower end of the lower glass 13 near the side. The first grinding angle 1311 and the second grinding angle 1312 of the two right-angle structures 131 are symmetrically arranged.

[0029] Reference Figure 2 and Figure 3 The size of the first grinding angle 1311 is 0.2±0.1 mm, that is, the side of the lower glass 13 is indented inward by 0.2±0.1 mm near the lower end.

[0030] Reference Figure 2 and Figure 3 The size of the second grinding angle 1312 is 0.1-0.2 mm, that is, the lower end of the lower glass 13 is indented inwardly by 0.1-0.2 mm near the side.

[0031] Reference Figure 2 and Figure 3 By respectively setting a first grinding angle 1311 and a second grinding angle 1312 on the two right-angle structures 131 of the lower glass 13, when the FPC 20 is bent to the back of the display screen 10, the two right-angle structures 131 avoid the FPC 20 to avoid the two right angles at the lower end of the lower glass 13 from wearing the FPC 20 and breaking the wiring, thereby ensuring the normal connection of the FPC 20.
