Description

Technical Field

[0001] The utility model relates to the technical field of display modules, and in particular to a display module for improving the problem of FPC connector damage. Background Art

[0002] The FPC on the display screen is generally connected to the motherboard of the electronic device through a BTB connector. In order to ensure the quality of the display screen is good and stable before leaving the factory, the display screen undergoes about 3 functional tests. During the test, the test machine and the operator may be at risk of deforming the steel sheet and crushing the connector, resulting in damage to the connector function. The more tests are conducted, the greater the probability of damage to the connector. In addition, after the display screen is subsequently turned over, since the shell of the electronic device must be made of hard material, the presence of the connector steel sheet may cause extrusion damage and vibration may cause the connector to loosen.

[0003] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a display module that improves the problem of FPC connector damage.

[0005] The technical solution of the utility model is as follows: The utility model provides a display module for improving the problem of FPC connector damage, including: a module FPC, a connector is provided on the module FPC, a steel sheet is provided on the back of the connector, a buffer foam is attached to the steel sheet, the size of the buffer foam is 0.1mm-0.15mm larger than the size of the steel sheet on one side, the compression amount of the buffer foam is 35%-65%, and the thickness of the buffer foam is 0.25mm-0.5mm.

[0006] Furthermore, the size of the buffer foam is 0.1 mm larger than the size of the steel sheet on one side.

[0007] Furthermore, the compression amount of the buffer foam is 35%.

[0008] Furthermore, the thickness of the buffer foam is 0.35 mm.

[0009] Furthermore, the display module also includes a liquid crystal module, and the module FPC is bound and connected to the liquid crystal module.

[0010] Furthermore, the display module also includes a backlight module, and the backlight module is stacked on the lower layer of the liquid crystal module.

[0011] By adopting the above scheme, the beneficial effect of the utility model is that by arranging the buffer foam on the steel sheet on the back of the connector of the module FPC, a buffering effect can be played, and the problems of crushing the steel sheet and the connector can be avoided during the test operation. After the display screen is installed, the elastic squeezing ability of the buffer foam can also be used to ensure the stability of the connection and avoid the steel sheet and the electronic equipment shell from being squeezed to damage the connector.

[0015] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] The utility model provides a display module for improving the problem of FPC connector damage, comprising: a module FPC 1, a connector 13 is arranged on the module FPC 1, a steel sheet 11 is arranged on the back of the connector 13, a buffer foam 12 is attached to the steel sheet 11, the size of the buffer foam 12 is 0.1mm larger than the size of the steel sheet 11 on one side, that is, the buffer foam 12 is larger than the steel sheet 11, and the distance between the edge of the buffer foam 12 and the corresponding edge of the steel sheet 11 is 0.1mm, which can ensure that the foam 12 can completely protect the steel sheet 11 under the condition of attachment tolerance, the compression amount of the buffer foam 12 is 35%, and the thickness is 0.35mm, which can ensure that a good protection effect is achieved while avoiding adverse effects on the thickness of the module FPC 1.

[0017] Furthermore, the display module further comprises a liquid crystal module and a backlight module, the module FPC 1 is bound and connected to the liquid crystal module, and the backlight module is stacked and arranged under the liquid crystal module.

[0018] In summary, the beneficial effect of this solution is that by arranging a buffer foam on the steel sheet on the back of the connector of the module FPC, a buffering effect can be achieved, thereby avoiding problems such as crushing the steel sheet and the connector during test operations. After the display screen is installed, the elastic squeezing ability of the buffer foam can also be used to ensure the stability of the connection and avoid damage to the connector due to squeezing of the steel sheet and the electronic equipment housing.
