The bottom side of the display device is provided with a front frame 102 and a front frame connector 103. The front frame 102 is fixedly connected with the front frame connector 103. The thickness of the front frame 102 is 0.1-0.3 mm, and the thickness of the front frame connector 103 is 0.4-0.5 mm. The front frame connector 103 is fixedly connected with the folding edge portion 1043. The height difference between the surface of the front frame 102 and the surface of the second polaroid of the liquid crystal panel 101 is 0-0.3 mm. The surface of the front frame 102 is flush with the surface of the second polaroid of the liquid crystal panel 101, or the surface of the front frame 102 protrudes from the surface of the second polaroid of the liquid crystal panel 101 by a height less than or equal to 0.3 mm.

[0034] The front frame 102 is lapped on the surface of the edge portion of the opposite substrate of the liquid crystal panel 101. The height difference between the surface of the front frame 102 and the surface of the second polaroid is 0-0.2 mm, or the front frame 102 is lapped on the surface of the second polaroid of the liquid crystal panel 101.

The major axis of each shock-absorbing pad is 0.5-0.8 mm, and the minor axis is 0.3-0.5 mm. The shock-absorbing pads are made of silicone material. The Shore hardness of the shock-absorbing pads is 50-60 degrees, which is used to buffer the pressure of the front frame 102 on the liquid crystal panel 101. Through the technical scheme, the front frame 102 and the liquid crystal panel 101 can be stably lapped, and the liquid crystal panel 101 can be prevented from being damaged.

[0036] The liquid crystal panel 101 is fixed on the glue frame 1042 by a third adhesive tape 1044.

[0037] The inner side of the front frame 102 (the side opposite to the outer side of the front frame 102) is provided with a plurality of reinforcing ribs extending along the length direction of the front frame 102 and arranged in parallel with each other. The cross section of each reinforcing rib is triangular, and the base of the triangle is fixedly connected to the inner side of the front frame 102. The length direction of the reinforcing rib is consistent with the length direction of the front frame 102, and the two ends of each reinforcing rib extend to a position 5-8 mm away from the end of the front frame 102. The reinforcing rib can be integrally formed with the front frame 102 by die forming, or can be fixedly arranged on the inner side of the front frame 102 by welding. The material of the reinforcing rib is the same as that of the front frame 102. At the middle position between the two ends of the front frame 102, a main reinforcing rib is arranged, and the height of the main reinforcing rib is 1.2-1.5 times the height of the other reinforcing ribs. A plurality of auxiliary reinforcing ribs are symmetrically arranged on the two sides of the main reinforcing rib, and the height of the auxiliary reinforcing ribs gradually decreases from the connection position with the main reinforcing rib to the two ends, and the height difference between adjacent two auxiliary reinforcing ribs is 0.1-0.2 mm. By arranging the reinforcing ribs in this way, the deformation of the front frame 102 under external force can be effectively prevented, especially the sinking of the middle position of the front frame 102.

[0038] The folding edge portions 1043 are uniformly distributed along the bottom side edges of the back plate 1041, for example, one folding edge portion 1043 is arranged every 50-100 mm on the bottom side edges of the back plate 1041.

Positioning blocks are arranged at the two ends of the front frame 102, and the thickness of the positioning blocks can be adjusted in the range of 0.1-0.2 mm, which is used to effectively control the relative position between the front frame 102 and the second polarizing plate of the liquid crystal panel 101. The surface flatness error of the front frame 102 is controlled within 0.05 mm. By designing the positioning structure in this way, it can be ensured that the surface of the front frame 102 is strictly flush with the surface of the second polarizing plate of the liquid crystal panel 101, and the appearance effect of the display device is improved.

[0042] To make the surface of the front frame 102 flush with the surface of the second polarizing sheet of the liquid crystal panel 101, the bottom of the front frame 102 is provided with a plurality of height adjustment assemblies.

The spherical support head is in contact with the back surface of the liquid crystal panel 101, and the height of the front frame 102 relative to the liquid crystal panel 101 can be effectively adjusted by rotating the fine adjustment screw. Through the design of such height adjustment assemblies, it can be ensured that the surface of the front frame 102 is always flush with the surface of the second polarizing sheet of the liquid crystal panel 101.

Specifically, a plurality of convex portions are arranged on the contact surface of the front frame 102, and a groove corresponding to each convex portion is arranged on the contact surface of the front frame connector 103. The cross section of each convex portion is trapezoidal. The cross section of the groove is also trapezoidal, and the size of the groove matches the size of the convex portion, but a gap of 0.05 millimeters to 0.08 millimeters is reserved to facilitate assembly.
