Packing gasket for protecting liquid crystal display panel semi-finished product

Abstract

The invention relates to a packing gasket for protecting a liquid crystal display panel semi-finished product. The packing gasket for protecting the liquid crystal display panel semi-finished product comprises first separation portions and second separation portions extending from the side faces of the first separation portions in the radial direction, wherein the thickness of the first separation portions is larger than that of the second separation portions. Cavities which can contain circuit board assemblies are formed between the second separation portions of the packing gasket and the adjacent packing gasket, and the height of the cavities is larger than the distance between the first separation portions of every two adjacent packing gaskets. Accordingly, the negative effect generated due to the fact that the maximum thickness of the printed circuit board assemblies is larger than the thickness of a liquid crystal display panel can be weakened.

Description

technical field [0001] The invention relates to the field of packaging engineering, in particular to a packaging gasket used to protect semi-finished products of liquid crystal panels. Background technique [0002] As complete machine manufacturers successively built their own backlight, module, and complete machine assembly factories, and LCD panel manufacturers produced liquid crystal panel semi-finished products (Open Cell) with higher profits than liquid crystal panel finished products, making liquid crystal panel semi-finished products become liquid crystal panels. The main shipment form of the factory. Such as figure 1 As shown, the liquid crystal panel semi-finished product 100 includes a liquid crystal screen 30, a printed circuit board assembly 10, and a flexible circuit board 20 whose two ends are respectively connected to the liquid crystal screen 30 and the printed circuit board assembly 10. The printed circuit board assembly 10 includes a printed circuit board ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome that in the prior art, because the maximum thickness of the printed circuit board assembly is greater than the thickness of the liquid crystal screen, the half-finished liquid crystal panel and the packaging gasket are alternately stacked on one side of the printed circuit board assembly behind the packing box. Problems that gradually slope and protrude upwards
