It should be noted that, in the step S10, it is determined whether another panel module is adjacent to the top of the receiving cavity, and whether a distance between another display panel and the top of the receiving cavity is equal to a thickness of the cover plate, in this embodiment, the thickness of the cover plate is at least 5 mm.

It is also worth mentioning that, by the above-mentioned method, it is not dependent on the conventional positioning edge method, and further, the display panel product (flexible printed circuit board) without the positioning edge or positioning angle can be packaged, and by the application of the anti-slip pad and the buffer material, the packaging safety and reliability of the display panel (flexible printed circuit board) can be improved.

That is, compared with the packaging method of packaging the panel module with a plurality of flexible circuit boards by positioning edges, the packaging method provided by the invention can further achieve the purpose of protecting the safety and reliability of the plurality of flexible circuit boards.

In addition, in another preferred embodiment of the present invention, the step S01 further includes the following steps:

step S011: a base plate is provided.

Step S012: the bottom plate is placed at the bottom of the containing groove.

In this other preferred embodiment, by performing step S011 and step S012, the packaging structure is provided with a plurality of buffer materials, a plurality of anti-slip pads and a plurality of panel modules by the bottom plate, and the possibility of damage caused by placing the first display module when the thickness of the first buffer material is not enough is reduced.

Further, in another preferred embodiment, the step S11 further includes the following steps:

step S111: a package cover is provided, which includes a cover slot.

Step S112: the tray is covered by the packaging cover, and meanwhile, the tray is accommodated in the covering groove.

In this embodiment, the packaging structure can be stacked on another packaging structure by performing steps S111 and S112.

In addition, the packaging structure of the present invention is subjected to a drop test and a random vibration test, respectively. The Vibration test mainly simulates the external stress of a product in various transportation processes, and the test modes include Random Vibration (Random Vibration) and Sine Vibration (Sine Vibration). The random vibration simulation product has better structural quality and transportation resistance.

The package structure random vibration test requirements are as follows:

the unit under test package should withstand the following mechanical testing without degradation of the internal components. This includes all optical requirements. And the following package random vibration test, conducted according to the Apple company (Apple) test specification, should meet all the requirements specified herein. Where only zero functional and appearance failures are allowed:

1. and (3) testing and reducing pressure: none.

2. And (4) using a transport package.

3. Pressure grade: trucks and air.

4. The power spectral density test is started using truck-borne vector samples, and if no fault is found, the power spectral density test is started using the vector samples in the transport.

5. Test axis and sequence: x-axis, Y-axis, Z-axis.

6. Duration per axis: for 30 minutes.

7. Weight: 0.

8. reading points: behind each axis.

9. The operation state is as follows: and (4) non-operation.

Referring to fig. 9 and 10, it can be seen that the result is that the total root mean square acceleration (Grms) in truck delivery (as shown in fig. 9) is 1.49g, the test result values are all smaller than the predetermined value in comparison with the ISO-vibration tolerance table, and the positions of the cushioning material and the display panel are in the stable state.

And the total root mean square acceleration (Grms) during the transportation (as shown in fig. 10) is 0.73g, the test results are all less than the predetermined value in comparison with the ISO-vibration tolerance table, and the positions of the cushioning material and the display panel are all in a stable state.

In addition, the drop test requires the following:

1. the orientation of the package is defined by the orientation of the cells within the package, as shown in FIG. 11.

2. The drop height of the test was 91 cm, and the order of drop was tested, as shown in FIG. 12.

Through the above two tests, the positioning-free edge packaging structure of the display panel has passed the experiment, and the overall appearance of the display panel is inspected, and the inspection result is no abnormality, and the electrical function inspection of the display panel, the plurality of first flexible circuit boards and the plurality of second flexible circuit boards is also no abnormality.

In summary, the packaging structure and the packaging method thereof of the present invention have the following advantages:

1. the invention can pack the display panel product without depending on the traditional positioning edge way, and the external force or collision is generated in the process of carrying or transporting the display panel product after the display panel product is packed, thereby achieving the purpose of preventing the product from colliding and damaging or preventing the circuit board assembly from being damaged. The package safety of the display panel (including flexible circuit board) without positioning edge is improved, and the anti-slip pad can prevent the positions of the panel module and the buffer material from slipping, thereby improving the reliability.

2. The design of the tray accommodating groove can be suitable for more sizes to be utilized and achieve recycling, and the tray can not be used once or for a specific size.

3. The packaging process and the unpacking process of the display panel can be better packaged and unpacked directly, and more chances of damaging the display panel body or the flexible circuit board in the packaging process or the unpacking process are avoided.

While the invention has been described with reference to specific embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
