1. Field of the Invention
The present invention relates to a waterproofing backing adhesive structure, especially a waterproofing backing adhesion for being adhered between the front cover and the display panel that prevents detachment of the waterproofing backing adhesive structure from the front cover or the display panel due to a bubble.
2. Description of the Related Art
There are two major methods of waterproof design for current electronic products. One is by using the installation of an O-type gasket. Though the O-type gasket has the advantage of reuse, it needs a larger space for installation, so it is not suitable for application in small lightweight electronic products. The other is by using a waterproof backing adhesive. A waterproof backing adhesive can be applied in small lightweight electronic products and can provide a good waterproofing effect as well; however, the following problems will occur while it is in use.

However, it can be noticed from the above description that once an bubble 95 develops on the same corresponding location (the odds of having another bubble at the same spot are very low) of the another rib 16 and expands as well and causes the failure of the rib 16, the problem of losing the waterproofing function of the waterproofing backing adhesive structure 1 can arise, as mentioned in the prior art. Therefore, the quantity of the ribs 16 installed in the backing adhesive main body 10 of the present invention, within a certain range of the width, is not limited to two, as shown in

It is to be noted that the above embodiments are only for illustration of the preferred embodiments of the present invention. In order to avoid redundancies, not all possible combinations are recorded in detail. However, those skilled in the art should understand that any implementations of the above-mentioned principles can be modified as needed; any designs that can form air chambers 30 in the backing adhesive main body 10 can fall within the scope of the present invention. It is to be understood that the formations of air chambers 30 with ribs 16 and with sockets 18 are actually the same in concept. In other words, from the viewpoint of the upper surface of the ribs 16, the spaces between each of the ribs 16 can be considered as the sockets 18; on the other hand, from the viewpoint of the upper surface of the inner sockets 18, the structures surrounding the upper surface of the inner sockets 18 can be considered as each of the ribs 16. Thus, the two formations of the air chambers 30 in the embodiments share the same relative concept. Additionally, it is preferable to have each of the air chambers 30 independent and without connections, but it does not exclude the possibility of having local or nearby air chambers 30 connected.
It is noted that the above-mentioned embodiments are only for illustration. It is intended that the present invention cover modifications and variations of the present invention provided they fall within the scope of the following claims and their equivalents. Therefore, it will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention.
