Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display modules, in particular to an anti-static liquid crystal display module. Background Art

[0002] To put it simply, the LCD module is a screen + backlight assembly. The display component of an LCD TV is the LCD module, which is equivalent to the cathode ray tube in a CRT. Other parts include power circuits, signal processing circuits, and of course, the outer shell. The module is mainly divided into a screen and a backlight assembly. The two parts are assembled together, but they are independent of each other when working (that is, the circuits are not related).

[0003] At present, the display module of mobile phones is mainly composed of panel, FPC, driver IC and backlight. The mobile phone provides the necessary power and control model to the driver IC of the display module through FPC, so that it drives the panel and displays the required picture. There is usually a certain area on the FPC for SMT of some electronic components such as resistors, capacitors and diodes required by the driver IC to filter, stabilize the voltage and protect the corresponding circuit from electrostatics to ensure the normal operation of the driver IC. However, most of these electronic components are exposed to the outside and are easily damaged by electrostatics caused by the external environment or the operator's body contact during the production process, causing the corresponding circuit to fail to work properly and the display screen to fail to display normally. For this reason, an anti-static liquid crystal display module is proposed. Utility Model Content

[0004] Based on this, it is necessary to provide an anti-static liquid crystal display module to address the above technical problems. A layer of insulating film is first attached to the surface of the electronic component area, and a copper foil of a certain thickness is attached to the insulating film. The copper foil is in contact with the leaked copper around the component area on the FPC, so that the generated static electricity is conducted through the copper foil and introduced into the electrostatic release network of the display module through the leaked copper of the FPC, thereby blocking and releasing static electricity.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An anti-static liquid crystal display module, comprising:

[0007] A display module, wherein a driver IC is provided on the display module, and the display module is connected to an FPC via the driver IC;

[0008] An electronic component area, which is provided on the FPC and is used for resistors, capacitors and diodes required for chip driver ICs;

[0009] A first copper leakage area, which surrounds the periphery of the electronic component area and is arranged on the FPC;

[0010] An anti-static element, which is arranged on the electronic component area and cooperates with the copper leakage area to form anti-static protection for the electronic components in the electronic component area;

[0011] The antistatic component includes an insulating film and a copper foil 1, wherein the insulating film covers and is attached to the surface of the antistatic component, and the copper foil 1 is attached to the insulating film, and the edges around the copper foil 1 are in contact with the copper leakage area 1;

[0012] When static electricity is released to the electronic component area, it is conducted by the copper foil and introduced into the static electricity release network of the display module through the copper leakage area.

[0013] Furthermore, a copper leakage area 2 is disposed around the periphery of the copper leakage area 1, and both the copper leakage area 2 and the copper leakage area 1 are connected to the electrostatic discharge network of the display module.

[0014] Furthermore, the anti-static component also includes a copper foil 2 attached to the outer edge of the copper foil 1.

[0015] Furthermore, the edges around the second copper foil are in contact with the second copper leakage area.

[0016] Furthermore, a heat dissipation element is provided on the top of the anti-static element for heat dissipation protection of the electronic component area under electrostatic protection.

[0017] Furthermore, the heat dissipation element includes heat-conductive foam, which contacts the heat dissipation components of the whole machine to transfer and dissipate heat after the display module is assembled.

[0018] Furthermore, the thermally conductive foam comprises an inner thermally conductive foam and an outer thermally conductive foam;

[0019] The inner heat-conducting foam is attached to the top of the first copper foil, and the outer heat-conducting foam is attached to the top of the second copper foil.

[0020] Furthermore, a groove is formed on the surfaces of the inner heat-conducting foam and the outer heat-conducting foam, and a central heat-conducting foam is embedded in the groove.

[0021] Furthermore, both ends of the central heat-conducting foam are cut with locking ends, and the inner side of the outer heat-conducting foam is cut with locking grooves matching the locking ends;

[0022] The outer heat-conducting foam is buckled and locked with the locking end on the central heat-conducting foam through the locking groove.

[0023] Furthermore, the central heat-conductive foam protrudes above the inner heat-conductive foam and the outer heat-conductive foam;

[0024] After the display module is assembled, the central thermal conductive foam is squeezed so that the inner thermal conductive foam and the outer thermal conductive foam are in contact with the heat dissipation components of the entire machine.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] The utility model provides an anti-static liquid crystal display module. An insulating film is firstly attached to the surface of the electronic component area. A copper foil of a certain thickness is attached to the insulating film. The periphery of the copper foil is in contact with the leaking copper around the electronic component area on the FPC. The generated static electricity is conducted through the copper foil and introduced into the static electricity release network of the display module through the leaking copper of the FPC, which plays a role in blocking and releasing static electricity, thereby effectively protecting the electronic component area. When the copper foil cannot effectively release all the static electricity, the excess static electricity is shielded by the insulating film, which plays a secondary protection role.

[0027] Copper foil 2 is added at the edge of copper foil 1 and used in conjunction with copper leakage area 2. When static electricity is released from the outside to the electronic component area, the static electricity first contacts copper foil 2, and copper foil 2 can be connected to copper foil 1 to conduct static electricity through copper leakage area 1 and copper leakage area 2, thereby improving the anti-static performance. At the same time, since copper foil 1 and copper foil 2 are both provided with thermal conductive foam, the heat generated by the electronic components can be diffused and transferred through copper foil 2 and copper foil 1, so that the heat can be diffused more quickly and evenly on the heat dissipation components of the entire machine, thereby achieving more effective heat dissipation.

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0044] As described in the background art, most electronic components are exposed to the outside and are easily damaged by static electricity caused by the external environment or operator's physical contact during the manufacturing process, causing the corresponding circuit to malfunction and the display screen to malfunction.

[0045] In order to solve this technical problem, the utility model provides an anti-static liquid crystal display module, which is applied to a liquid crystal display module.

[0046] Specifically, please refer to Figure 1-Figure 7 , the anti-static liquid crystal display module specifically includes:

[0047] Display module 1, on which a driver IC 11 is disposed, and the display module 1 is connected to an FPC 12 via the driver IC 11;

[0048] The electronic component area 13 is provided on the FPC 12 and is used for the resistors, capacitors and diodes required for the chip driver IC 11;

[0049] The copper leakage area 12 is arranged on the FPC 12 around the periphery of the electronic component area 13;

[0050] The anti-static element 3 is arranged on the electronic component area 13 and cooperates with the copper leakage area 2 to form anti-static protection for the electronic components in the electronic component area 13;

[0051] The anti-static component 3 includes an insulating film 31 and a copper foil 32. The insulating film 31 covers and is attached to the surface of the anti-static component 3, and the copper foil 32 is attached to the insulating film 31, and the edges of the copper foil 32 are in contact with the copper leakage area 2.

[0052] When static electricity is released to the electronic component area 13 , it is conducted by the copper foil and introduced into the static electricity release network of the display module 1 through the copper leakage area 1 2 .

[0053] The anti-static liquid crystal display module provided by the utility model has an insulating film 31 firstly attached to the surface of the electronic component area 13, and a copper foil 32 of a certain thickness is attached to the insulating film 31. The copper foil 32 is in contact with the copper leakage area 2 around the electronic component 13 on the FPC 12, so that the generated static electricity is conducted through the copper foil 32 and introduced into the static electricity release network of the display module 1 through the copper leakage area 2 on the FPC 12, which plays a role in blocking and releasing static electricity, thereby effectively protecting the electronic component area 13. When the copper foil 32 cannot effectively release all the static electricity, the excess static electricity is shielded by the insulating film 31, which plays a secondary protection role.

[0054] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0055] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0056] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0057] Example 1

[0058] Please refer to Figure 1 and Figure 2 As shown, an anti-static liquid crystal display module, a display module 1, a driving IC 11 is provided on the display module 1, and the display module 1 is connected to an FPC 12 through the driving IC 11;

[0059] The electronic component area 13 is provided on the FPC 12 and is used for the resistors, capacitors and diodes required for the chip driver IC 11;

[0060] The copper leakage area 12 is arranged on the FPC 12 around the periphery of the electronic component area 13;

[0061] The antistatic component 3 is arranged on the electronic component area 13 and cooperates with the copper leakage area 2 to form antistatic protection for the electronic components in the electronic component area 13, wherein the antistatic component 3 includes an insulating film 31 and a copper foil 32, wherein the insulating film 31 covers and is attached to the surface of the antistatic component 3, and the copper foil 32 is attached to the insulating film 31, and the edges around the copper foil 32 are in contact with the copper leakage area 2, when static electricity is released to the electronic component area 13, it is conducted by the copper foil and introduced into the electrostatic release network of the display module 1 through the copper leakage area 2.

[0062] like Figure 2 As shown, when there is external static electricity released near the electronic component area 13, the generated static electricity is conducted through the copper foil 32 and introduced into the static electricity release network of the display module 1 through the copper leakage area 2 on the FPC 12, which plays a role in blocking and releasing static electricity, thereby effectively protecting the electronic component area 13. When the copper foil 32 cannot effectively release all static electricity, the excess static electricity is shielded by the insulating film, which plays a secondary protection role, so as to ensure the isolation and protection of static electricity during the actual application and assembly process of the operator, thereby reducing the situation of static electricity damage.

[0063] Example 2

[0064] The anti-static liquid crystal display module provided in Example 1 is further optimized, specifically, as follows: Figure 3 As shown, a second copper leakage area 4 is arranged around the outer periphery of the first copper leakage area 2, and the second copper leakage area 4 and the first copper leakage area 2 are both connected to the electrostatic discharge network of the display module 1, and the anti-static element 3 also includes a second copper foil 33 attached to the outer edge of the first copper foil 32, and the edges around the second copper foil 33 are in contact with the second copper leakage area 4;

[0065] like Figure 3 As shown, by adding the copper leakage area 2 4 and the copper foil 2 33, when static electricity is released from the outside to the electronic component area 13, the static electricity first contacts the copper foil 2 33, and the copper foil 2 33 can be connected with the copper foil 1 32, and the static electricity is jointly conducted through the copper leakage area 1 2 and the copper leakage area 2 4, thereby improving the anti-static performance.

[0066] Example 3

[0067] The anti-static liquid crystal display module provided in Example 2 is further optimized, such as Figure 3 , Figure 4 As shown, a heat dissipation element 5 is provided on the top of the anti-static element 3 for heat dissipation protection of the electronic component area 13 under electrostatic protection;

[0068] The heat dissipation element 5 includes a heat-conducting foam 51. After the display module 1 is assembled, the heat-conducting foam 51 contacts the heat dissipation components of the whole device to form heat transfer and heat dissipation. The heat-conducting foam 51 includes an inner heat-conducting foam 510 and an outer heat-conducting foam 511.

[0069] The inner thermal conductive foam 510 is attached to the top of the copper foil 1 32 , and the outer thermal conductive foam 511 is attached to the top of the copper foil 2 33 ;

[0070] In actual application, the heat generated by the electronic component area 13 can be transferred to the copper foil 1 32 through the insulating film 31. Since the copper foil 1 32 and the copper foil 2 33 are in an on state, the copper foil 1 32 and the copper foil 2 33 can be used together to transfer the heat generated by the electronic component area 13 to the inner thermal conductive foam 510 and the outer thermal conductive foam 511 attached thereto. Since the inner thermal conductive foam 510 and the outer thermal conductive foam 511 are in contact with the heat dissipation components of the entire machine, the heat transferred from the inner thermal conductive foam 510 and the outer thermal conductive foam 511 will eventually be dissipated together through the heat dissipation components of the entire machine, thereby achieving more effective heat dissipation protection.

[0071] Example 4

[0072] The anti-static liquid crystal display module provided in Example 3 is further optimized, such as Figure 5 , Figure 6 and Figure 7 As shown, a groove 52 is formed on the surfaces of the inner heat-conducting foam 510 and the outer heat-conducting foam 511, and a central heat-conducting foam 53 is embedded in the groove 52;

[0073] Both ends of the central heat-conducting foam 53 are cut with locking ends 531 , and the inner side of the outer heat-conducting foam 511 is cut with locking grooves 532 that match the locking ends 531 ;

[0074] The outer heat-conducting foam 511 is buckled and locked with the locking end 531 on the central heat-conducting foam 53 through the locking groove 532;

[0075] The central heat-conducting foam 53 protrudes above the inner heat-conducting foam 510 and the outer heat-conducting foam 511. After the display module 1 is assembled, the central heat-conducting foam 53 is squeezed so that the inner heat-conducting foam 510 and the outer heat-conducting foam 511 are in contact with the heat dissipation components of the whole machine;

[0076] Through the cooperation between the locking groove 532 and the locking end 531, the central heat-conducting foam 53 pasted in the outer groove 52 can support the outer heat-conducting foam 511 on the outside, thereby ensuring the connection strength between the outer heat-conducting foam 511 and the overall heat dissipation element 5, and preventing the outer heat-conducting foam 511 from being separated from the heat dissipation element 5 during its actual application;

[0077] At the same time, since the central thermally conductive foam 53 protrudes above the inner thermally conductive foam 510 and the outer thermally conductive foam 511, when the display module 1 is buckled on the back shell for installation, the central thermally conductive foam 53 will interfere with the heat dissipation component on the back shell, resulting in the central thermally conductive foam 53 being compressed by the interference force after the display module 1 and the external back shell are assembled as a whole. The compressed central thermally conductive foam 53 will cause the outer thermally conductive foam 511 to contact the heat dissipation component on the back shell, thereby ensuring the stability of the contact between the heat dissipation element 5 and the heat dissipation component on the back shell, and avoiding the formation of gaps on the contact surface, which makes it impossible for the heat dissipation component to effectively dissipate the heat transferred to the heat dissipation element 5.

[0078] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0079] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive.
