Row laminating.
A kind of waterproof display module, wherein, made using method for waterproofing as above.
Beneficial effect：Component of the present invention after to touch screen and LCD laminatings carries out nano coating process, makes component table
Last layer coating is plated in face, makes component have water-proof function；And fitted the component after coating is plated with backlight module, then
The FPC of the FPC of backlight module and LCD is welded, and encapsulation process is carried out to welding position using liquid glue, so that whole
Individual display module is provided with water-proof function.
Description of the drawings
Fig. 1 is a kind of explosive view of waterproof display module preferred embodiment of the invention.
Specific embodiment
The present invention provides a kind of waterproof display module and its method for waterproofing, to make the purpose of the present invention, technical scheme
And effect is clearer, clear and definite, below the present invention is described in more detail.It should be appreciated that described herein be embodied as
Example is not intended to limit the present invention only to explain the present invention.
Present invention is generally directed to current display module and the improvement that carries out, as shown in figure 1, display module generally comprise it is tactile
Touch screen 100（Touch Panel）, LCDs 300（LCD）With backlight module 500, touch screen 100 and LCDs 300
It is respectively provided with flexible PCB（FPC）, the flexible PCB 110 of touch screen as depicted 100, the flexibility of LCDs 300
Circuit board 310, while backlight module 500 also has the FPC510 of extraction, traditional technique cannot accomplish to have above-mentioned display module
There is water-proof function, for this problem, the method for waterproofing of waterproof display module provided by the present invention, it includes step：
Touch screen 100 and LCD300 are fitted, then the component after laminating nano coating process is carried out into, component is made
Plated surface last layer coating；
The component after coating will be plated to be fitted with backlight module 500, and by the FPC510 of backlight module 500 with
The FPC310 of LCD300 is welded, then carries out encapsulation process to welding position using liquid glue.
Due to all flexible circuit board on touch screen 100 and LCDs 300（FPC）, there is each electron-like unit device on FPC
Part, these electronic devices and components all can not work in water, once contact water, it is possible to cause short circuit.In order to solve this problem,
Component after laminating, using nano coating process, is plated last layer by the present invention after touch screen 100 and LCD300 are fitted
Coating, the coating can isolate impact of the conducting liquids such as water to circuit so that touch screen 100 and LCDs 300 have can
With the function of working in water conservancy project.
Specifically, the step of nano coating is processed includes：Component after laminating is positioned over for nano coating process
Equipment cavity in, then by cavity evacuation, last layer coating is then plated on assembly surface.Wherein, the He of touch screen 100
The first adopted glue 200 of LCD300 laminatings, can be fitted using OCA glue, and OCA glue refers to transparent optical cement, due to touching
The inside of screen 100 and LCD300 is touched without gas, and joint place is also solid gum, so evacuation is processed not having to whole process
Affect, and the component after coating treatment is provided with the ability worked in water, that is, be provided with water-proof function.
Further, the thickness of the coating be Nano grade, it is preferable that the thickness of the coating be 1nm ~ 10nm, the thickness
Degree can not only isolate impact of the water to circuit, and the other functions such as the electric conductivity of component are not interfered with again, wherein, preferably can be with
It is 5nm.
For backlight module 500, because it is formed by various diaphragms stacking, but due to each film in backlight module 500
It is, with the presence of gap, therefore there is air between piece, if being also carried out nano coating process, is then also required to advance evacuation, if
Evacuation, then internal air can expand, cause the inside bonding structure of backlight module 500 to be destroyed, so, in present invention enforcement
In example, only the independent component to touch screen and LCD carries out nano coating process, and backlight module is not processed, for the back of the body
The waterproof of light module, using endless rubber belt laminating reflector plate and backlight glue frame, and can preferably adopt the more preferable glue of viscosity
Band, such as black and white glue, more specifically can be the X653-2 black and white glue of better performances, and to avoid, laminating is not firm to have caused gap to lead
Cause the entrance of water.
Then, backlight module is fitted with the component after nano coating process, its second glue 400 for adopting
Endless rubber belt may also be employed or OCA glue is fitted, to avoid the entrance of water.
Because backlight module 500 has the FPC of extraction, the FPC of backlight module 500 to need to be welded with the FPC of LCD300,
In order that whole display module possesses water-proof function, encapsulation process need to be carried out to welding position, it is preferred to use liquid glue is to welding
Position carries out sealing process.
Additionally, the present invention also provides a kind of waterproof display module, made using described method for waterproofing.
In sum, component of the present invention after to touch screen and LCD laminatings carries out nano coating process, makes component table
Last layer coating is plated in face, makes component have water-proof function；And fitted the component after coating is plated with backlight module, then
The FPC of the FPC of backlight module and LCD is welded, and encapsulation process is carried out to welding position using liquid glue, so that whole
Individual display module is provided with water-proof function.
It should be appreciated that the application of the present invention is not limited to above-mentioned citing, and for those of ordinary skills, can
To be improved according to the above description or be converted, all these modifications and variations should all belong to the guarantor of claims of the present invention
Shield scope.
