Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to a display module capable of preventing a double-sided copper exposed structure from being torn. Background Art

[0002] In the mobile phone industry, the anti-interference and electrostatic protection performance of the display module is required to be very high. Therefore, a large area of ​​exposed copper is added to the module FPC of the display module. These exposed coppers are usually set at the same position on the front and back sides of the module FPC. This structural design leads to problems such as the exposed copper peeling off from the FPC, the exposed copper area of ​​the module FPC and the edge of the covering film cracking, which leads to module damage and other problems.

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

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a display module which can prevent the double-sided copper exposed structure from being torn.

[0005] The technical solution of the utility model is as follows: The utility model provides a display module for preventing the double-sided copper exposed structure from tearing, comprising: a module FPC, on which a front-side copper exposed layer and a back-side copper exposed layer are formed in the same position, the edges of the front-side copper exposed layer and the back-side copper exposed layer are covered with a covering film, and the positions of the windows of the front-side copper exposed layer and the windows of the back-side copper exposed layer are staggered.

[0006] Furthermore, the width of the edges of the front copper-exposed surface and the back copper-exposed surface covered by the covering film is greater than or equal to 0.5 mm.

[0007] Furthermore, the copper-exposing windows on the front side and the copper-exposing windows on the back side are both rectangular.

[0008] Furthermore, the edges of the copper-exposed windows on the front side and the copper-exposed windows on the back side are both straight lines, and the distance between the edge of the copper-exposed window on the front side and the corresponding edge of the copper-exposed window on the back side is greater than or equal to 0.5 mm.

[0009] By adopting the above scheme, the beneficial effect of the utility model is that: by providing protective film covering the edges of the exposed copper on the front side and the exposed copper on the back side in the module FPC, and staggering the window positions of the exposed copper on the front side and the exposed copper on the back side, the structural strength of the module FPC is improved, the problem of peeling and tearing of the exposed copper is avoided, and the yield of the product can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2It is a schematic diagram of the reverse side of a module FPC according to an embodiment of the present invention.

[0012] Figure 3 It is a cross-sectional schematic diagram of the copper exposed portion of the front side of the module FPC according to an embodiment of the present invention. DETAILED DESCRIPTION

[0013] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Please refer to Figures 1 to 3 In this embodiment, the utility model provides a display module for preventing the double-sided copper exposed structure from tearing, comprising: a module FPC 1, on which a front-side exposed copper 2 and a back-side exposed copper 3 with the same projection position are formed, the edges of the front-side exposed copper 2 and the back-side exposed copper 3 are covered with a covering film 4, and the projection positions of the windows of the front-side exposed copper 2 and the windows of the back-side exposed copper 3 are staggered.

[0015] Furthermore, the width of the edges of the front exposed copper 2 and the back exposed copper 3 covered by the covering film 4 is greater than or equal to 0.5 mm.

[0016] Furthermore, the window for exposing the copper 2 on the front side and the window for exposing the copper 3 on the back side are both rectangular.

[0017] Further, the edges of the windows of the copper-exposed front surface 2 and the windows of the copper-exposed back surface 3 are both straight lines, and the distance between the edge of the window of the copper-exposed front surface 2 and the corresponding edge of the window of the copper-exposed back surface 3 is greater than or equal to 0.5 mm. Preferably, the area of ​​the windows of the copper-exposed front surface 2 and the windows of the copper-exposed back surface 3 are the same, and the windows of the copper-exposed front surface 2 and the windows of the copper-exposed back surface 3 are staggered by 0.5 mm in the transverse direction and the longitudinal direction, respectively.

[0018] Please continue to refer to Figures 1 to 3 In this solution, by providing a covering film 4 on the edges of the front copper exposure 2 and the back copper exposure 3, the covering film 4 can achieve corresponding protection and fixing effects, thereby preventing the front copper exposure 2 and the back copper exposure 3 from falling off or peeling off, and the setting positions of the windows of the front copper exposure 2 and the back copper exposure 3 are staggered, so that the corresponding edges of the windows of the front copper exposure 2 and the back copper exposure 3 do not overlap, which helps to improve the strength of the module FPC 1 at the copper exposure position and avoid the problem of tearing.

[0019] In summary, the beneficial effect of this solution is that by providing a protective film covering the edges of the exposed copper on the front side and the exposed copper on the back side of the module FPC, and staggering the window positions of the exposed copper on the front side and the exposed copper on the back side, the structural strength of the module FPC is improved, the problem of peeling and tearing of the exposed copper is avoided, and the yield of the product can be improved.

[0020] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
