Description

Buffer accessories, display panel packaging box including buffer accessories, and packaging method

technical field

The present application relates to the technical field of packaging, and in particular, to a buffer accessory, a display panel packaging box including the buffer accessory, and a packaging method.

Background technique

Currently, components for electronic products are mass-manufactured at different manufacturers, then packaged and shipped to assembly plants for assembly. As one of the important components of electronic products with display function, the display panel needs to be transported to the terminal manufacturer after production is completed to be assembled with other components to form electronic products with display function. Because the display panel has poor anti-collision performance and is easily broken when subjected to impact or vibration, the display panel is usually transported in a packaging box, and a buffer is provided in the packaging box to further reduce the risk of damage to the display panel.

With the rapid development of display technology, the display panel is developing towards a narrow frame or even no frame, which puts forward higher requirements for the packaging and transportation of the display panel. As shown in FIG. 1 , the borderless liquid crystal display panel 100 has a first side portion 101 , a second side portion 102 , a third side portion 103 and a fourth side portion 104 , wherein the fourth side portion 104 is provided with a circuit board 105 , the circuit board 105 is provided with a flexible connecting material 106, that is, the fourth side portion 104 is a flexible connecting side. As shown in FIG. 2, the polarizer disposed on the color filter substrate 107 is defined as the upper polarizer 108. In order to prevent light leakage, each side portion (ie: the first side portion, the second side portion and the The edge of the upper polarizer at the third side) respectively exceeds the corresponding edge of the color filter substrate by a distance d1 of about 0.1 mm, and the excess part is coated with photocuring glue 109 to seal.

technical problem

As shown in FIG. 3 and FIG. 4 , in the packaging box 110 of the existing display panel, the borderless liquid crystal display panel 100 is limited by the retaining walls 111 arranged at the four corners, and the silicone sheet 112 is attached to the retaining walls 111 . to cushion the external impact. However, after the borderless liquid crystal display panel is packaged in the packaging box of the existing display panel, there will be a certain gap between the borderless liquid crystal display panel and each silicone sheet. Therefore, the borderless liquid crystal display panel is subjected to external force during transportation. The shock will shake, causing the side-coated photocuring glue to collide with the silicone sheet. Since the elastic modulus of the photo-curable adhesive is an order of magnitude smaller than that of silica gel, the photo-curable adhesive will be deformed under the action of impact. The position of the polarizer is shifted; or, the photo-curing glue is squeezed to a flat state, causing the upper polarizer to directly collide with the silicone sheet. If the impact is light, bubbles will appear on the edge of the upper polarizer, and if the impact is heavy, the upper polarizer will appear on the edge. The polarizer is detached from the problem of the liquid crystal display panel, thereby causing a significant negative impact on the quality of the display panel.
