Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] As described in the background art, currently, the touch keys of the display module are not integrated with the touch of the LCD, the manufacturing process is complex, resulting in a relatively high cost of the product. Moreover, since the key FPC is separately led out on the main board of the whole machine, there are many parts of the whole machine, and the stacking is complicated and the cost is relatively high.

[0028] To solve this technical problem, the present utility model provides a display module integrated with mechanical keys, which integrates mechanical keys on the display screen FPC, optimizes product stacking and cost, and enhances product competitiveness.

[0029] Specifically, please refer to Figures 1-4 , the display module integrated with mechanical keys specifically includes:

The display screen FPC1 and the auxiliary FPC2 adopt a PET transparent substrate and are connected to each other through traces. The first mechanical key 4 and the second mechanical key 5 are led to the interface through traces. The traces can adopt conductive silver paste traces. Of course, the traces can also adopt copper traces or other metal traces. The manufacturing process of the lead area of the present utility model is not limited. It can adopt a common copper-clad PET substrate and etch the copper-clad into traces. Of course, other materials and processes can also be adopted.

During use, the first mechanical key 4 and the second mechanical key 5 are attached to the key holes on the cover plate to realize the control function of the keys. Thus, the touch keys are integrated on the LCD, realizing the integration of the keys and the FPC. Compared with the traditional scheme, it is more concise and has a lower cost. Moreover, due to the overall thin thickness of the display screen FPC1 and the auxiliary FPC2, the display screen FPC1 and the auxiliary FPC2 can be directly pasted on the lower border of the whole machine, occupying less space and being more easily assembled with the structure. At the same time, the first mechanical key 4 and the second mechanical key 5 are installed on the auxiliary FPC2. Because there is a bending area 3 at the connection between the display screen FPC1 and the auxiliary FPC2, it can be bent arbitrarily, enabling the positions of the first mechanical key 4 and the second mechanical key 5 to be arranged arbitrarily according to customer requirements. At the same time, it optimizes product stacking and cost, does not increase the process, saves the process of separately manufacturing and binding the external FPC of the touch keys, improves production efficiency, and greatly enhances the competitiveness of the product.

It is more concise and has a lower cost compared with the traditional scheme. Moreover, due to the overall thin thickness of the display screen FPC1 and the secondary FPC2, the display screen FPC1 and the secondary FPC2 can be directly pasted on the lower border of the whole machine, occupying less space and being more easily assembled with the structure. At the same time, the first mechanical button 4 and the second mechanical button 5 are installed on the secondary FPC2. Since the bending area 3 is provided at the connection between the display screen FPC1 and the secondary FPC2, it can be bent arbitrarily, so that the positions of the first mechanical button 4 and the second mechanical button 5 can be arranged arbitrarily according to customer requirements.
