Packaging box for display panel

Abstract

The invention discloses a packaging box for a display panel. The packaging box comprises a box body with an open top face and limiting assemblies. The box body comprises a containing groove in the middle and first inserting groove in the first side wall of the box body. The limiting assemblies comprise adjusting pieces, the adjusting pieces comprise vertical matched portions and pressing portions bent relative to the matched portions, the limiting assemblies are inserted into the first inserting grooves, multiple depths of the adjusting pieces on the box body are selectively fixed, the pressing portions stretch into the containing groove towards the middle of the box body, and the pressing portions are used for pressing a PCB of the display panel in the containing groove. Through the limiting assemblies in the packaging box, the display panel is fixed reliably and is convenient to take out, and panel damage caused by random bouncing of one side of the PCB can be avoided. Meanwhile, the same clamping effect can be achieved when the inner diameter is changed after the packaging box is used for a long time, and COF breaking caused by Open cell swing can be avoided.

Description

technical field [0001] The invention relates to the field of display device packaging, in particular to a packaging box for a display panel. Background technique [0002] LCD panel manufacturers have different approaches to the shipment of TV LCD modules. Observing the current TV LCD panel market, semi-finished products, that is, Open Cells without backlights are gradually gaining favor. This kind of Open Cell is a semi-finished product assembled from components such as liquid crystal panels, color filters, and polarizers. It only has basic driver ICs and PCB boards, and lacks backlight boards and power components. After LCD panel manufacturers ship to TV manufacturers, TV manufacturers can purchase backlight panels separately, and the procurement cost can be greatly reduced compared with finished panels. [0003] Such as Figure 1A Generally, the Open Cell 1 is connected to a PCB (Printed Circuit Board, printed circuit board) board 3 through a COF 2 (Chip On Flex, or, Chi...

AI Technical Summary

Problems solved by technology

In this way, it is impossible to avoid the Open Cell 1 jumping up and down in the vertical direction and the large shaking in the horizontal direction during the transportation or stacking of the panels, which will cause the electronic components on the PCB board to be damaged by impact and COF 2. hurt

The reliability of packing box 4 is reduced, the product of Open Cell 1 is damaged, and unnecessary losses are caused
