The packing box 119 includes a plurality of cases 110 stacked and a fixing structure provided at the bottom of the cases 110, the cartridge body 110 includes a first receiving groove 210, a second receiving groove 220, a third receiving groove 230 and first and second buffer grooves 240 and 250, the display panel includes a display panel and a circuit board connected to the display panel, the first receiving groove 210 receives the display panel, the second receiving groove 220 receives the circuit board, the third receiving groove 230 is used for placing a drying agent, the corners of the display panel are placed in the first buffer groove 240, the edge of the buffer display panel is cut into the packing box 100, the second buffer groove saves the cost of the packing box 100, the buffer protection display panel, the box body 110 and the box cover 120 of the packing box 100 are generally made of foam materials, since the packing box 100 made of the foamed material has a large shrinkage, it is difficult to completely achieve the specification limit in every size. In order to prevent the package 100 from interfering with the case cover 120 and the case body 110, which may result in the package 100 not being opened directly, the package further includes a sealing structure 140; the sealing structure 140 is arranged around the opening, and the sealing structure 140 is made of an elastic material; in a direction perpendicular to a plane where the opening of the case body 110 is located, the cover 120 is formed with a first surface 111, the corresponding case body 110 is formed with an opposite surface 121, the first surface 111 of the cover 120 faces the opposite surface 121 of the case body 110, the first surface 111 of the cover 120 and the opposite surface 121 of the case body 110 are disposed opposite to each other, a gap 130 is formed between the first surface 111 of the cover 120 and the opposite surface 121 of the case body 110, and the sealing structure 140 seals the gap 130.

The first surface 111 of the cover 120 is opposite to the opposite surface 121 of the case 110, two surfaces are perpendicular to the plane of the opening of the case 110, and a gap 130 is formed between the two opposite surfaces, so that the case 110 and the cover 120 are not completely contacted in the direction parallel to the plane of the opening of the case 110, and the case 110 and the cover 120 are still in sealing fit in the direction of the plane of the opening of the case 110, and meanwhile, the sealing structure 140 is made of an elastic material, so that the contractibility of the cover 120 and the case 110 is buffered, and the case 110 and the cover 120 are not interfered by the contractibility when opened. This is to some production lines of snatching automatically, avoids leading to box body 110 and lid 120 can not normally separate, causes the production line to report to the police and shuts down, has seriously influenced production efficiency and productivity, so clearance 130 avoids box body 110 and lid 120 to interfere each other, as a technical means of preventing interfering, and effectual packing carton 100 that prevents is interfered, improves the productivity. Specifically, in the direction of the plane where the opening of the box body 110 is located, the second surface 112 is formed on the box cover 120 and is arranged opposite to the plane where the opening of the box body 110 is located, and the second surface 112 of the box cover 120 and the plane where the opening of the box body 110 is located are tightly attached without a gap 130, so that the box cover 120 and the box body 110 are tightly attached, and the air tightness is improved to prevent water vapor from entering and affecting the performance of the display panel.

As shown in fig. 2, the sealing structure 140 includes a first sidewall 143, a second sidewall 144, and a connecting member 145, the first sidewall 143 and the second sidewall 144 are oppositely disposed, the connecting member 145 connects the first sidewall 143 and the second sidewall 144, and the first sidewall 143 and the second sidewall 144 are disposed around the packing box 100; the sealing structure is arranged in the packaging box 100, and the sealing effect is strong.
