Description

Technical Field

[0001] The present invention relates to the field of display technology, and more specifically, to a display module and a display device. Background Art

[0002] With the rapid development of flat panel displays and the improvement of people's living standards, display devices are increasingly used in people's daily lives. Connectors are an indispensable part of display devices. Their main function is to bridge the gap between blocked or isolated circuits in the display device, so that current can flow and the circuit can achieve its intended function. The form and structure of connectors are ever-changing. There are various forms of connectors depending on the application object, frequency, power and application environment.

[0003] The connectors used to provide signal connection between the circuit board for driving signals and the display panel in existing display devices are mainly plug-in connectors. The use of plug-in connectors can easily and quickly complete the electrical connection between the display panel and the power supply circuit board, which is conducive to industrial mass production. However, the current connectors are mainly conventional designs, with exposed metal conductive pins and no anti-foolproofing function. It is easy to cause misaligned plugging and unplugging during live plugging. Once improper misaligned plugging and unplugging occurs, it is easy to cause static electricity to damage the panel, affecting the panel quality and product yield; and the operator's brute force misaligned and oblique plugging can easily cause problems such as connector damage.

[0004] Therefore, it is a technical problem that needs to be solved urgently by those skilled in the art to provide a display module and a display device that can avoid electrostatic damage to the panel during the process of plugging and unplugging the connector under power, which is beneficial to protecting the equipment and improving the product yield. Summary of the invention

[0005] In view of this, the present invention provides a display module and a display device to improve the problem of misaligned plugging and unplugging of connectors during live plugging and unplugging of the module, which affects the product yield.

[0006] The present invention discloses a display module, including a display panel, a flexible circuit board and a printed circuit board, the display panel including a binding area, the flexible circuit board and the printed circuit board are bound and electrically connected to the display panel in the binding area; the flexible circuit board and the printed circuit board are connected by a connector; the connector includes a first connecting plate and a second connecting plate; the first connecting plate includes a groove on the side facing the second connecting plate, and the groove includes a plurality of first pins; the second connecting plate includes a plurality of second pins on the side facing the first connecting plate, the first pins correspond to the second pins one by one, the second pins are inserted into the grooves, and the second pins are in contact and electrically connected with the first pins; a partial area of ​​at least one first pin is coated with a first insulating layer.

[0007] Based on the same inventive concept, the present invention also discloses a display device, which includes the above-mentioned display module.

[0008] Compared with the prior art, the display module and display device provided by the present invention achieve at least the following beneficial effects:

[0009] The display module of the present invention includes a display panel and a flexible circuit board and a printed circuit board bound and electrically connected to the display panel. The flexible circuit board and the printed circuit board are bound and electrically connected to the display panel in the binding area of ​​the display panel. The flexible circuit board and the printed circuit board are connected through a connector, and then the printed circuit board provides the display panel with an electrical signal to drive it to realize functions such as display through the circuit on the flexible circuit board. The connector includes a first connecting plate and a second connecting plate. The first connecting plate includes a groove on the side facing the second connecting plate, and the groove includes a plurality of first pins. The second connecting plate includes a plurality of second pins on the side facing the first connecting plate. The first pins correspond to the second pins one by one. By plugging and unplugging the first connecting plate and the second connecting plate of the connector, the electrical connection between the display panel and the printed circuit board can be completed conveniently and quickly, which is conducive to the industrial mass production of the module. The present invention sets a partial area of ​​at least one first pin in the first connecting plate to be coated with a first insulating layer. When the flexible circuit board and the printed circuit board are electrically connected through the connector, the second pin on the second connecting plate is inserted into the groove opened in the first connecting plate and is electrically connected with the corresponding first pin. Since the first insulating layer is coated on a partial area of ​​the first pin, static electricity breakdown caused by the instantaneous contact between the first pin and the second pin at the moment of wrong insertion can be avoided, thereby preventing static electricity damage to the display panel during the operation of plugging and unplugging the connector with power. And since the first insulating layer of the present invention is not coated on the surface of the entire first pin, it will not affect the conductivity of the first pin itself, and it can be ensured that after the first connecting plate and the second connecting plate are plugged in, the second pin and the area of ​​the first pin not coated with the first insulating layer can still contact to achieve the conductive transmission effect between the first connecting plate and the second connecting plate.

[0010] Of course, any product implementing the present invention does not necessarily need to achieve all of the above-mentioned technical effects at the same time.

[0045] Please refer to Figure 1-Figure 5 , Figure 1 is a schematic diagram of a planar structure of a display module provided by an embodiment of the present invention, Figure 2 yes Figure 1 Schematic diagram of the connection structure between the flexible circuit board and the printed circuit board, Figure 3 yes Figure 2 Schematic diagram of the exploded structure of the cross-section structure of the connector. Figure 4 yes Figure 3 Schematic diagram of the three-dimensional structure of the first connecting plate, Figure 5 yes Figure 4 A partial enlarged structural diagram of the middle Q region, the display module 000 provided in this embodiment includes a display panel 10, a flexible circuit board 20 and a printed circuit board 30, the display panel 10 includes a binding area BA, and the flexible circuit board 20 and the printed circuit board 30 are bound and electrically connected to the display panel 10 in the binding area BA;

[0046] The flexible circuit board 20 and the printed circuit board 30 are connected via a connector 40;

[0047] The connector 40 includes a first connection plate 401 and a second connection plate 402;

[0048] The first connecting plate 401 includes a groove 4010 on one side facing the second connecting plate 402, and the groove 4010 includes a plurality of first pins 4011;

[0049] The second connecting plate 402 includes a plurality of second pins 4021 on one side facing the first connecting plate 401. The first pins 4011 correspond to the second pins 4021 one by one. The second pins 4021 are inserted into the grooves 4010. The second pins 4021 are in contact and electrically connected with the first pins 4011.

[0050] A partial region of at least one first pin 4011 is coated with a first insulating layer 50 .

[0051] Specifically, the display module 000 of this embodiment includes a display panel 10 and a flexible circuit board 20 and a printed circuit board 30 bound and electrically connected to the display panel 10. The flexible circuit board 20 and the printed circuit board 30 are bound and electrically connected to the display panel 10 in the binding area BA of the display panel 10. Optionally, the flexible circuit board 20 can be bound to the display panel 10 in the binding area BA of the display panel 10. The flexible circuit board 20 and the printed circuit board 30 are connected through a connector 40, and then the printed circuit board 30 provides the display panel 10 with an electrical signal to drive it to realize functions such as display through the lines on the flexible circuit board 20.

[0052] The printed circuit board 30 (PCB, Printed Circuit Board, also known as printed circuit board) of this embodiment is a provider of electrical connections for electronic components. Optionally, the printed circuit board 30 may include a substrate and electronic components, drive circuits, etc. integrated on the substrate. The flexible circuit board 20 (FPC, Flexible Printed Circuit, also known as flexible printed circuit board) is a highly reliable and extremely flexible printed circuit board made of polyimide or polyester film as a substrate. The display module 000 of this embodiment includes a display panel 10 and a printed circuit board 30. The electrical connection between the display panel 10 and the printed circuit board 30 generally adopts the connection method of the flexible circuit board 20. The flexible circuit board 20 can be bound to the display panel 10 to realize the transmission of electrical signals between the display panel 10, and the flexible circuit board 20 and the printed circuit board 30 can be connected by the connector 40 to realize the transmission of electrical signals. The flexible circuit board 20 generally includes a pressing end 20A and a gold finger end 20B. The pressing end 20A of the flexible circuit board 20 can be pressed within the binding area BA of the display panel 10 to achieve electrical connection with the display panel 10. At the same time, a connector 40 connected to the printed circuit board 30 is provided at the gold finger end 20B of the flexible circuit board 20. The connector 40 of this embodiment includes a first connecting plate 401 and a second connecting plate 402. The optional first connecting plate 401 can be provided at one of the positions of the gold finger end 20B of the flexible circuit board 20 or the corresponding positions on the printed circuit board 30, and the second connecting plate 402 can be provided at the position of the gold finger end 20B of the flexible circuit board 20 or the corresponding positions on the printed circuit board 30. The first connecting plate 401 includes a groove 4010 on one side facing the second connecting plate 402 . The groove 4010 includes a plurality of first pins 4011 . The second connecting plate 402 includes a plurality of second pins 4021 on one side facing the first connecting plate 401 . The first pins 4011 correspond to the second pins 4021 one by one.

[0053] Optionally, the depth of the groove 4010 may not penetrate the thickness of the first connecting plate 401, and a plurality of first pins 4011 may be arranged on the inner side wall of the groove 4010, so that when the first connecting plate 401 is subsequently plugged into the second connecting plate 402, the second pins 4021 on the second connecting plate 402 can be plugged into the groove 4010 and electrically connected to the corresponding first pins 4011, and the first connecting plate 401 and the second connecting plate 402 are electrically connected through the contact between the first pins 4011 on the first connecting plate 401 and the second pins 4021 on the second connecting plate 402, so that the transmission of electrical signals can be completed between the driving circuit board 30 and the flexible circuit board 20. In this embodiment, the electrical connection between the flexible circuit board 20 and the printed circuit board 30 can be completed by plugging and unplugging the first connecting plate 401 and the second connecting plate 402 of the connector 40, and the display panel 10 and the printed circuit board 30 are electrically connected through the flexible circuit board 20. The structure in which the flexible circuit board 20 and the printed circuit board 30 are electrically connected by plugging and unplugging the connector 40 in this embodiment can conveniently and quickly complete the electrical connection between the display panel 10 and the printed circuit board 30, which is conducive to the industrial mass production of modules.

[0054] However, the pins on the connectors in the prior art are generally of conventional conductive design, with the metal of the pins exposed and without anti-foolproofing function. When the operator is plugging and unplugging the first connecting plate and the second connecting plate, it is easy for the operator to plug and unplug the plate while it is powered on and plug and unplug the plate in a misaligned manner. The operation of plugging and unplugging while it is powered on is easy to cause static electricity to damage the display panel when it is misaligned. In addition, the operation of brute force, misaligned and oblique insertion is easy to cause damage to the connector, thereby reducing the yield of the module.

[0055] In order to solve the above problem, in this embodiment, a partial area of ​​at least one first pin 4011 in the first connecting plate 401 is coated with a first insulating layer 50. Optionally, a partial area of ​​the first pin 4011 in the first connecting plate 401 can be coated with the first insulating layer 50, that is, only a partial area of ​​the first pin 4011 is coated with the first insulating layer 50 with an insulating effect. When the flexible circuit board 20 and the printed circuit board 30 are electrically connected through the connector 40, the second pin 4021 on the second connecting plate 402 is inserted into the groove 4010 opened in the first connecting plate 401, and the second pin 4021 is in contact and electrically connected with the corresponding first pin 4011. Since the first insulating layer 50 is coated on a partial area of ​​the first pin 4011, electrostatic breakdown caused by the instantaneous contact and conductive conduction between the first pin 4011 and the second pin 4021 at the moment of wrong insertion can be avoided, thereby preventing electrostatic damage to the display panel 10 during the operation of plugging and unplugging the connector 40 with power on. Furthermore, since the first insulating layer 50 of this embodiment is not coated on the entire surface of the first pin 4011, it will not affect the conductivity of the first pin 4011 itself, and it can be ensured that after the first connecting plate 401 and the second connecting plate 402 are plugged in, the second pin 4021 and the area of ​​the first pin 4011 not coated with the first insulating layer 50 can still contact to achieve the conductive transmission effect between the first connecting plate 401 and the second connecting plate 402. In this embodiment, the first insulating layer 50 has been coated on a part of the first pin 4011 during the manufacturing process of the connector 40, and even after the first connecting plate 401 and the second connecting plate 402 are subsequently plugged in, there is no need to remove the first insulating layer 50, which is conducive to reducing the overall manufacturing process of the module.

[0056] It should be noted that the present embodiment does not specifically limit the type and structure of the display panel 10. In specific implementation, the solution of the present embodiment can be applied to any type of display panel 10. It is only necessary to meet the requirement that the drive signal on the display panel 10 needs to be electrically transmitted through the flexible circuit board 20 and the drive circuit board 30, and the connector 40 used can be the design structure of the present embodiment. The present embodiment does not elaborate on the structure of the display panel 10.

[0057] It can be understood that the drawings of this embodiment are only illustrative of the shape and number of the first pin 4011 and the second pin 4021 in the connector 40. In specific implementation, the shape and number of the first pin 4011 and the second pin 4021 in the connector 40 are not limited thereto, and other arrangements are also possible. It is only necessary that only a portion of the surface of the first pin 4011 in the first connecting plate 401 is coated with the first insulating layer 50 to avoid electrostatic damage when the connector 40 is operated under power during the plugging and unplugging process. This embodiment is not limited thereto.

[0058] In some optional embodiments, please refer to Figure 1-Figure 5 , Figure 6 and Figure 7 , Figure 6 yes Figure 4 Schematic diagram of the top view of the first connecting plate, Figure 7 yes Figure 6 A schematic cross-sectional structure diagram along the A-A' direction, in this embodiment, the shape of the orthographic projection of the groove 4010 of the first connecting plate 401 on the plane where the first connecting plate 401 is located includes a long strip;

[0059] The groove 4010 includes a first side wall 4010A and a second side wall 4010B. A first pin 4011 includes a first sub-portion 4011A and a second sub-portion 4011B. The first sub-portion 4011A is disposed on the first side wall 4010A, and the second sub-portion 4011B is disposed on the second side wall 4010B.

[0060] In a direction Z perpendicular to the plane where the first connecting plate 401 is located, the first sub-portion 4011A and / or the second sub-portion 4011B includes a first area 4011X and a second area 4011Y, and the first area 4011X is located on a side of the second area 4011Y close to the bottom of the groove 4010;

[0061] Along a direction X parallel to the first sub-portion 4011A and pointing toward the second sub-portion 4011B, a thickness D1 of the first sub-portion 4011A of the first region 4011X is smaller than a thickness D2 of the first sub-portion 4011A of the second region 4011Y; and / or,

[0062] Along a direction parallel to the first subportion 4011A and directed toward the second subportion 4011B, a thickness D3 of the second subportion 4011B of the first region 4011X is smaller than a thickness D4 of the second subportion 4011B of the second region 4011Y.

[0063] This embodiment explains that the side of the first connecting plate 401 facing the second connecting plate 402 includes a groove 4010. The groove 4010 can be a groove structure formed by the surface of the side of the first connecting plate 401 facing the second connecting plate 402 being recessed in a direction away from the second connecting plate 402. The shape of the orthographic projection of the groove 4010 in the plane where the first connecting plate 401 is located in this embodiment can be a long strip, or the shape of the orthographic projection of the groove 4010 in the plane where the first connecting plate 401 is located can also be a closed ring or square. This embodiment is not limited to this. The figure of this embodiment takes the shape of the orthographic projection of the groove 4010 in the plane where the first connecting plate 401 is located as a rectangle as an example for explanation. The groove 4010 of the first connecting plate 401 includes a first side wall 4010A and a second side wall 4010B. Optionally, as shown in FIG. Figure 3As shown, the groove 4010 can be understood as including a groove bottom 4010C, and a first side wall 4010A and a second side wall 4010B located on opposite sides of the groove bottom 4010C. The plane where the first side wall 4010A is located can be understood as intersecting with or being perpendicular to the plane where the first connecting plate 401 is located, and the plane where the second side wall 4010B is located can be understood as intersecting with or being perpendicular to the plane where the first connecting plate 401 is located. In this embodiment, the first pin 4011 of the first connecting plate 401 can be arranged on the two side walls of the groove 4010. Specifically, a first pin 4011 of the first connecting plate 401 includes a first sub-portion 4011A and a second sub-portion 4011B. The first sub-portion 4011A and the second sub-portion 4011B Part 4011B can be understood as an independent structure arranged on the two side walls of the groove 4010, the first sub-part 4011A is arranged on the first side wall 4010A, and the second sub-part 4011B is arranged on the second side wall 4010B, and a first pin 4011 of a first connecting board 401 is formed by a first sub-part 4011A and a second sub-part 4011B. When the second connecting board 402 is plugged into the first connecting board 401, the second pin 4021 of the second connecting board 402 contacts the first sub-part 4011A and the second sub-part 4011B of a first pin 4011 in the groove 4010 respectively to realize the electrical connection between the corresponding pins of the first connecting board 401 and the second connecting board 402.

[0064] In this embodiment, in a direction Z perpendicular to the plane where the first connecting plate 401 is located, the first sub-portion 4011A and / or the second sub-portion 4011B includes a first area 4011X and a second area 4011Y with different thicknesses, that is, in a direction Z perpendicular to the plane where the first connecting plate 401 is located, the first sub-portion 4011A includes a first area 4011X and a second area 4011Y with different thicknesses; or, the second sub-portion 4011B includes a first area 4011X and a second area 4011Y with different thicknesses, or the first sub-portion 4011A and the second sub-portion 4011B both include a first area 4011X and a second area 4011Y with different thicknesses, the first area 4011X is closer to the groove bottom 4010C than the second area 4011Y, and along a direction X parallel to the first sub-portion 4011A and pointing to the second sub-portion 4011B, the thickness D1 of the first sub-portion 4011A of the first area 4011X is less than that of the second area 4011Y. The thickness D2 of the first sub-section 4011A; the thickness D3 of the second sub-section 4011B of the first zone 4011X is smaller than the thickness D4 of the second sub-section 4011B of the second zone 4011Y, so that the first pin 401 formed by the two independent first sub-sections 4011A and the second sub-sections 4011B has a larger insertion space for the second pin 4021 formed at a position close to the bottom 4010 of the groove, while the insertion space for the second pin 4021 formed at a position close to the second connecting plate 402 is smaller, and the shape of the second pin 4021 arranged on the second connecting plate 402 matches the shape of the first pin 4011, so that after the second pin 4021 is plugged into the position of the first pin 4011 of the shape, the second pin 4021 on the second connecting plate 402 can be firmly embedded in the first pin 4011 of the shape, which is beneficial to improve the stability of the first connecting plate 401 and the second connecting plate 402 after plugging.

[0065] In addition, the first pin 401 formed by two independent first sub-parts 4011A and second sub-parts 4011B in this embodiment has a smaller insertable space for the second pin 4021 formed near the second connecting plate 402, so that when the second pin 4021 is plugged into the corresponding first pin 4011, the first contact is the second area 4011Y with a thicker thickness of the first sub-part 4011A and the second sub-part 4011B. If the misalignment is found, the plugging action can be stopped in time to avoid the second pin 4021 of the second connecting plate 402 from contacting too much and getting deeply embedded in the groove 4010 with the first pin 4011, which may be difficult to pull out during rework, thereby reducing the probability of damage to the pins of the connector 40 during the plugging and unplugging process.

[0066] In some optional embodiments, please continue to refer to Figure 1-Figure 5 , Figure 6 and Figure 7In this embodiment, the first insulating layer 50 is located on the surface of the first sub-portion 4011A of the second region 4011Y; and / or

[0067] The first insulating layer 50 is located on the surface of the second sub-portion 4011B of the second region 4011Y.

[0068] This embodiment explains that the first insulating layer 50 coated on the first pin 4011 can be located only on the surface of the first sub-portion 4011A of the second zone 4011Y, or the first insulating layer 50 can be located only on the surface of the second sub-portion 4011B of the second zone 4011Y, or the first insulating layer 50 can be located only on the surface of the first sub-portion 4011A and the second sub-portion 4011B of the second zone 4011Y. When the second connecting plate 402 is plugged downward onto the first connecting plate 401, the lower end of the charged second pin 4021 first contacts the surface of the first sub-portion 4011A and / or the second sub-portion 4011B of the first pin 4011 within the second zone 4011Y. Therefore, this embodiment is provided with the first insulating layer 50 only in the second zone 4011.

[0072] The first insulating layer 50 is coated on the first sub-portion 4011A of the first sub-region 4011Y1, and the first insulating layer 50 is coated on the second sub-portion 4011B of the first sub-region 4011Y1.

[0073] This embodiment explains that the first insulating layer 50 coated on the first pin 4011 can be located only on the surface of the first sub-portion 4011A of the second area 4011Y in a partial area, or the first insulating layer 50 can be located only on the surface of the second sub-portion 4011B of the second area 4011Y in a partial area, or the first insulating layer 50 can be located only on the surface of the first sub-portion 4011A and the second sub-portion 4011B of the second area 4011Y in a partial area.

In addition, since the first insulating layer 50 of this embodiment is only disposed on the first pin 4011 in the area of ​​the first sub-region 4011Y1, the coating material of the first insulating layer 50 can be saved, which is conducive to cost saving.

[0077] In some optional embodiments, please continue to refer to Figure 1-Figure 8 In this embodiment, the material of the first insulating layer 50 includes metal chelate.

[0078] This embodiment explains that the material of the first insulating layer 50 coated on the partial area of ​​the first pin 4011 may include a metal chelate. Optionally, in terms of cost, ease of acquisition, etc., an aluminum chelate may be selected. The metal chelate can be easily obtained by using a chelating agent to react with a metal alkoxide. The first insulating layer 50 of this embodiment uses a metal chelate, which can improve the adhesion with the first pin 4011 of the metal conductive material within a smaller area, avoid the problem of the first insulating layer 50 falling off when the coating area on the first pin 4011 is small, and ensure the coating firmness between the first insulating layer 50 and the first pin 4011.

[0079] Optionally, in the present embodiment, the thickness range of the first insulating layer 50 is 0.04-0.1 mm. The first insulating layer 50 is made of metal chelate material, which can ensure that the coating thickness of the first insulating layer 50 is relatively thin, only between 0.04-0.1 mm, thereby improving the coating firmness between the first insulating layer 50 and the first pin 4011, and avoiding the first insulating layer 50 occupying the plug-in space between the first pin 4011 and the second pin 4021.

[0080] In some optional embodiments, please refer to Figure 1 , Figure 2 and Fig. 9 , Fig.10 , Fig. 9 yes Figure 2 A schematic diagram of the exploded structure of the cross-sectional structure of the first sub-pin and the second sub-pin of the connector, Fig.10 yes Figure 2 Schematic diagram of the exploded structure of the cross-sectional structure of the third sub-pin and the fourth sub-pin of the connector. In this embodiment, the plurality of first pins 4011 at least include a first sub-pin 40111 and a third sub-pin 40112, and the signal connected to the first sub-pin 40111 and the signal connected to the third sub-pin 40112 are of different types;

[0081] The plurality of second pins 4021 at least include a second sub-pin 40211 and a fourth sub-pin 40212, and the signal connected to the second sub-pin 40211 and the signal connected to the fourth sub-pin 40212 are of different types;

[0082] The second sub-pin 40211 is plugged and corresponds to the first sub-pin 40111, and the fourth sub-pin 40212 is plugged and corresponds to the third sub-pin 40112;

[0083] like Fig. 9 and Fig.10 As shown, the shape of the first sub-pin 40111 is different from the shape of the third sub-pin 40112.

[0084] This embodiment explains that in the first connecting board 401 of the connector 40, the plurality of first pins 4011 can be designed with differentiated shapes, specifically, the plurality of first pins 4011 at least include a first sub-pin 40111 and a third sub-pin 40112, and the signal connected to the first sub-pin 40111 and the signal connected to the third sub-pin 40112 are of different types, that is, the plurality of first pins 4011 include at least two different types of signal pins, wherein the plurality of second pins 4021 in the second connecting board 402 at least include a second sub-pin 40211 corresponding to the first sub-pin 40111 plug-in, and a fourth sub-pin 40212 corresponding to the third sub-pin 40112 plug-in, and the plurality of first pins 4011 can be designed with differentiated shapes, and the plurality of second pins 4021 can also be designed with differentiated shapes accordingly, so that the first connecting board 402 can be designed with differentiated shapes. When the connecting plate 401 and the second connecting plate 402 are plugged in, if there is a problem of misaligned plugging, the second sub-pin 40211 will not correspond to the position of the first sub-pin 40111, and the fourth sub-pin 40212 will correspond to the position of the first sub-pin 40111; the fourth sub-pin 40212 will not correspond to the position of the third sub-pin 40112, and the second sub-pin 40211 will correspond to the position of the third sub-pin 40112. The first sub-pin 40111 on the first connecting plate 401 and the fourth sub-pin 40212 on the second connecting plate 402, which do not match in shape, cannot form a plug-in structure, that is, the fourth sub-pin 40212 cannot be plugged into the position of the first sub-pin 40111 embedded in the groove 4010, thereby avoiding the problem of misaligned plugging when the first connecting plate 401 and the second connecting plate 402 are plugged in, thereby achieving a better anti-foolproofing effect.

[0085] It can be understood that the present embodiment does not specifically limit the shape of the first sub-pin 40111 and the shape of the third sub-pin 40112 on the first connecting board 401. It is only necessary that the shape of the first sub-pin 40111 and the shape of the third sub-pin 40112 on the first connecting board 401 are different, and the second connecting board 402 cannot correspond to the first connecting board 401 when plugged downward.

The light-emitting element is connected to a first power signal, which is used to provide a power signal for driving the light-emitting element to emit light, such as a first power signal that may be a high-voltage power signal. The flexible circuit board 20 and the printed circuit board 30 are connected to a second power signal, which is used to provide a power signal for driving the flexible circuit board 20 and the printed circuit board 30.

In the present embodiment, the connection signals of the first sub-pin 40111 on the first connecting board 401 with a differentiated shape design and / or the second sub-pin 40211 on the second connecting board 402 include any one of the first power signal, the second power signal, and the touch drive signal. Since the first power signal, the second power signal, and the touch drive signal are all high-voltage drive signals, the signal connected to the sub-pins in the shape-differentiated design connector 40 is designed as a high-voltage drive signal in the present embodiment, which can better prevent the sub-pins connected to the high-voltage signal from being damaged by high voltage when the connecting boards are misaligned, thereby further reducing the probability of damage to the connector 40.

[0093] The shape of the first type first sub-pin 401111 is different from the shape of the second type first sub-pin 401112. The shape of the first protrusion 40111A corresponding to the optional first type first sub-pin 401111 is different from the shape of the first protrusion 40111A corresponding to the second type first sub-pin 401112.

Fig.18 As shown, due to the existence of the first groove 40211A and the second groove 40112B and the support of the first protrusion 40111A and the second protrusion 40212B), the second sub-pin 40211 on the misplaced second connecting plate 402 which is connected to the high-voltage signal and is easily damaged will not contact with the third sub-pin 40112 on the first connecting plate 401, and thus will not be electrically conductive, thereby avoiding the problem of electrostatic damage caused by the conduction of the easily damaged sub-pin which is connected to the high-potential signal at the moment of wrong insertion, which is beneficial to better protect the connector 40 from electrostatic damage, and thus is beneficial to improving the electrostatic protection effect of the display module 000.

[0099] In some optional embodiments, please refer to Figure 1 , Figure 2 , Fig.19 and Fig. 20 , Fig.19 yes Figure 2 A schematic diagram of an exploded structure of another cross-sectional structure of the first sub-pin and the second sub-pin of the connector, Fig. 20 yes Figure 2 Schematic diagram of the exploded structure of another cross-sectional structure of the third sub-pin and the fourth sub-pin of the connector. In this embodiment, among the plurality of second pins 4021, the volumes of the second sub-pin 40211 and the fourth sub-pin 40212 are different.

[0100] This embodiment explains that among the multiple second pins 4021 of the second connecting board 402, the volumes of the second sub-pin 40211 and the fourth sub-pin 40212 can be set to be different to distinguish the second pins 4021 connected to different types, such as the second sub-pin 40211 connected to a high potential signal that is easily damaged by static electricity and the fourth sub-pin 40212 connected to a low potential that is relatively less likely to be damaged by static electricity have different volumes. Optionally, the volume of the second sub-pin 40211 can be set to be larger than the volume of the fourth sub-pin 40212. It can be understood that the pluggable space of the first sub-pin 40111 on the first connecting board 401 that matches the second sub-pin 40211 is also larger, and the pluggable space of the third sub-pin 40112 on the first connecting board 401 that matches the fourth sub-pin 40212 is also larger. The space is small, so a fool-proof design is provided for connecting the second pin 4021 of different types. When the larger second sub-pin 40211 is misplaced and inserted into the position of the third sub-pin 40112 with a smaller insertable space, the second sub-pin 40211 that is connected to a high-potential signal and is easily damaged by static electricity cannot be inserted into the position of the third sub-pin 40112 with a smaller space. Therefore, a conductive path cannot be formed between the second sub-pin 40211 that is connected to a high-potential signal and is easily damaged by static electricity and the first connecting plate 401, thereby protecting the second sub-pin 40211 that is easily damaged by static electricity, avoiding the problem of static electricity damage caused by the conduction of the easily damaged sub-pin that is connected to a high-potential signal at the moment of wrong insertion, further protecting the connector 40 from static electricity damage, and improving the static electricity protection effect of the display module 000.

[0101] It can be understood that Fig.19 and Fig. 20 The second sub-pin 40211 and the fourth sub-pin 40212 have different volumes, which is reflected in Fig. 20 The fourth sub-pin 40212 is Fig.19 The overall size of the second sub-pin 40211 is smaller. In some other optional embodiments, such as Fig.19 and Fig.21 As shown, Fig.21 yes Figure 2 A schematic diagram of the exploded structure of another cross-sectional structure of the third sub-pin and the fourth sub-pin of the connector, in the direction X parallel to the plane where the first connecting plate 401 is located, the thickness D5 of the second sub-pin 40211 is greater than the thickness D6 of the fourth sub-pin 40212. At this time, in the direction X parallel to the plane where the first connecting plate 401 is located, the pluggable width of the first sub-pin 40111 on the first connecting plate 401 that matches the second sub-pin 40211 is also larger, and the pluggable width of the third sub-pin 40112 on the first connecting plate 401 that matches the fourth sub-pin 40212 is smaller, so that the first sub-pin 40111 on the first connecting plate 401 can be matched and plugged with the second sub-pin 40211 on the second connecting plate 402, and the third sub-pin 40112 on the first connecting plate 401 can be matched and plugged with the fourth sub-pin 40212 on the second connecting plate 402.

[0102] In some other optional embodiments, please refer to Figure 1 , Figure 2 , Fig.19 and Fig. 22 , Fig. 22 yes Figure 2A schematic diagram of the exploded structure of another cross-sectional structure of the third sub-pin and the fourth sub-pin of the connector, in the direction Z perpendicular to the plane where the first connecting plate 401 is located, the height H3 of the second sub-pin 40211 is less than the height H4 of the fourth sub-pin 40212. At this time, in the direction Z perpendicular to the plane where the first connecting plate 401 is located, the depth of the groove 4010 at the corresponding position of the first sub-pin 40111 on the first connecting plate 401 that matches the second sub-pin 40211 is less than the depth of the groove 4010 at the corresponding position of the third sub-pin 40112 on the first connecting plate 401 that matches the fourth sub-pin 40212. This embodiment explains that the second sub-pin 40211 and the fourth sub-pin 40212 have different volumes, which can also be reflected in that in the direction Z perpendicular to the plane where the first connecting plate 401 is located, the height H3 of the second sub-pin 40211 is smaller than the height H4 of the fourth sub-pin 40212, that is, the height of the second sub-pin 40211 that is easily damaged by static electricity and connected to a high-potential signal can be shorter, and the depth of the groove 4010 at the position of the first sub-pin 40111 on the first connecting plate 401 that matches it is also shallower. When misaligned plugging is performed, if the second sub-pin 40211 with a shorter height is inserted into the position of the third sub-pin 40112 on the first connecting plate 401 with a deeper depth, due to the second sub-pin The height H3 of the pin 40211 is smaller than the height H4 of the fourth sub-pin 40212, the depth of the groove 4010 at the corresponding position of the third sub-pin 40112 is deeper, and the second sub-pin 40211 will not contact the conductive part of the third sub-pin 40112 for conduction. Therefore, no conductive path can be formed between the second sub-pin 40211 that is easily damaged by static electricity and connected to a high-potential signal and the first connecting plate 401, thereby protecting the second sub-pin 40211 that is easily damaged by static electricity, avoiding the problem of static electricity damage caused by the conduction of the easily damaged sub-pin that is connected to a high-potential signal at the moment of wrong insertion, and further protecting the connector 40 from static electricity damage, thereby improving the static electricity protection effect of the display module 000.

[0103] In some optional embodiments, please refer to Fig.23 and Fig.24 , Fig.23 is another schematic diagram of a planar structure of a display module provided by an embodiment of the present invention, Fig.24 yes Fig.23 Schematic diagram of the connection structure of the flexible circuit board and the printed circuit board, in this embodiment, the bottom of the first connecting plate 401 away from the second connecting plate 402 includes a plurality of first conductive pads 601, and the first connecting plate 401 is bound and electrically connected to the printed circuit board 30 through the plurality of first conductive pads 601;

[0104] The bottom of the second connecting plate 402 facing away from the first connecting plate 401 includes a plurality of second conductive pads 602 , and the second connecting plate 402 is bound and electrically connected to the flexible circuit board 20 via the plurality of second conductive pads 602 .

[0105] This embodiment explains that when the flexible circuit board 20 and the printed circuit board 30 are electrically connected by directly plugging through the connector 40, the bottom of the first connecting plate 401 away from the second connecting plate 402 includes a plurality of first conductive pads 601, and the bottom of the second connecting plate 402 away from the first connecting plate 401 includes a plurality of second conductive pads 602. The first connecting plate 401 can be bound and electrically connected to the corresponding position of the printed circuit board 30 through the plurality of first conductive pads 601, and the second connecting plate 402 can be bound and electrically connected to the corresponding position of the flexible circuit board 20 through the plurality of second conductive pads 602. Then, the electrical contact between the pins of the first connecting plate 401 and the second connecting plate 402 of the connector 40 is realized to realize electrical conduction between the flexible circuit board 20 and the printed circuit board 30, so that the driving signal provided by the printed circuit board 30 is transmitted to the flexible circuit board 20 through the pins of the connector 40, and the flexible circuit board 20 is bound and electrically connected to the display panel 10 in the binding area BA of the display panel 10, and then the driving signal received by the printed circuit board 30 can be provided to the display panel 10, so as to provide the display panel 10 with a driving signal for realizing functions such as display.

[0106] It can be understood that, in this embodiment, each first conductive pad 601 on the first connecting board 401 and each first pin 4011 can be electrically connected to each other inside the first connecting board 401, and each second conductive pad 602 on the second connecting board 402 and each second pin 4021 can be electrically connected to each other inside the second connecting board 402 (the connecting circuit layer inside the connecting board is not shown in the figure). The connecting board itself can be understood as a structure including a circuit layer. This embodiment does not limit the circuit structure inside the connector 40, and it is only necessary to satisfy that the flexible circuit board 20 and the printed circuit board 30 can realize signal transmission through the connector 40.

[0107] In some optional embodiments, please refer to Fig.23 and Fig.25 , Fig.25 yes Fig.23 Schematic diagram of another connection structure of the flexible circuit board and the printed circuit board, in this embodiment, a selection switch 70 is set at the bottom of the first connecting plate 401 away from the second connecting plate 402, and the selection switch 70 controls whether the multiple first pins 4011 of the first connecting plate 401 are conductive or non-conductive.

[0108] This embodiment explains that the connector 40 for plugging and electrically connecting the flexible circuit board 20 and the printed circuit board 30 can be provided with a selection switch 70. Optionally, the selection switch 70 can be provided at the bottom of the first connecting plate 401 away from the second connecting plate 402. The selection switch 70 can be two or more, which are respectively provided at the bottom of both ends of the first connecting plate 401. The selection switch 70 is used to control the conductivity or non-conductivity of the multiple first pins 4011 of the first connecting plate 401. When the selection switch 70 is pressed, the multiple first pins 4011 on the first connecting plate 401 are electrically conductive. The first pin 4011 is conductively connected to the internal circuit layer of the first connecting board 401, and the first pin 4011 is energized. If the selection switch 70 is not pressed, the multiple first pins 4011 on the first connecting board 401 are not conductively connected to the internal circuit layer of the first connecting board 401, and the first pin 4011 is not energized. At this time, even if the operator makes an error in operation and misaligns the plug-in, electrostatic shock caused by the misaligned plug-in contact can be avoided, thereby protecting the connector 40 from electrostatic shock, thereby improving the electrostatic protection effect of the display module 000.

[0109] Optional, such as Fig.23 and Fig.26 As shown, Fig.26 yes Fig.23 Schematic diagram of the three-dimensional exploded structure of the connector, the selection switch 70 can also be set at the bottom of the groove 4010 opened on the first connecting plate 401, when the second pin 4021 of the second connecting plate 402 is correctly inserted into the groove 4010 of the first connecting plate 401, the protrusion 80 of the second connecting plate 401 will press the selection switch 70 at the corresponding position in the groove 4010, and the multiple first pins 4011 on the first connecting plate 401 will be conductive with the internal circuit layer of the first connecting plate 401, and the first pins 4011 will be charged; if the second pin 4021 of the second connecting plate 402 is misplaced and inserted into the first connecting plate In the groove 4010 of the connecting board 401, the protrusion 80 of the second connecting board 401 will not press the selection switch 70 at the corresponding position in the groove 4010, so the selection switch 70 is not pressed, and the multiple first pins 4011 on the first connecting board 401 are not conductive with the internal circuit layer of the first connecting board 401 itself, and the first pins 4011 are not charged, that is, when the first connecting board 401 and the second connecting board 402 are misaligned and plugged in, the selection switch 70 can avoid electrostatic damage caused by misaligned plugging contact, thereby protecting the connector 40 from electrostatic damage, thereby improving the electrostatic protection effect of the display module 000.

[0110] It is understandable that the present embodiment does not specifically limit the design structure and the location of the gate switch 70. Fig.25 and Fig.26It is only for illustration. In specific implementation, the setting position of the selection switch 70 is not limited to this. The selection switch 70 can be set according to actual design requirements, and this embodiment will not be described in detail here.

[0111] In some alternative embodiments, please refer to Fig. 27 , Fig. 27 1 is a schematic diagram of a planar structure of a display device provided in an embodiment of the present invention. The display device 111 provided in this embodiment includes the display module 000 provided in the above embodiment of the present invention. Fig. 27 The embodiment only takes a mobile phone as an example to illustrate the display device 111. It can be understood that the display device 111 provided in the embodiment of the present invention can be a computer, a television, a car display device or other display device 111 with a display function, and the present invention does not specifically limit this. The display device 111 provided in the embodiment of the present invention has the beneficial effects of the display module 000 provided in the embodiment of the present invention. For details, please refer to the specific description of the display module 000 in the above embodiments, and this embodiment will not be repeated here.

[0112] It can be seen from the above embodiments that the display module and display device provided by the present invention achieve at least the following beneficial effects:

[0113] The display module of the present invention includes a display panel and a flexible circuit board and a printed circuit board bound and electrically connected to the display panel. The flexible circuit board and the printed circuit board are bound and electrically connected to the display panel in the binding area of ​​the display panel. The flexible circuit board and the printed circuit board are connected through a connector, and then the printed circuit board provides the display panel with an electrical signal to drive it to realize functions such as display through the circuit on the flexible circuit board. The connector includes a first connecting plate and a second connecting plate. The first connecting plate includes a groove on the side facing the second connecting plate, and the groove includes a plurality of first pins. The second connecting plate includes a plurality of second pins on the side facing the first connecting plate. The first pins correspond to the second pins one by one. By plugging and unplugging the first connecting plate and the second connecting plate of the connector, the electrical connection between the display panel and the printed circuit board can be completed conveniently and quickly, which is conducive to the industrial mass production of the module. The present invention sets a partial area of ​​at least one first pin in the first connecting plate to be coated with a first insulating layer. When the flexible circuit board and the printed circuit board are electrically connected through the connector, the second pin on the second connecting plate is inserted into the groove opened in the first connecting plate and is electrically connected with the corresponding first pin. Since the first insulating layer is coated on a partial area of ​​the first pin, static electricity breakdown caused by the instantaneous contact between the first pin and the second pin at the moment of wrong insertion can be avoided, thereby preventing static electricity damage to the display panel during the operation of plugging and unplugging the connector with power. And since the first insulating layer of the present invention is not coated on the surface of the entire first pin, it will not affect the conductivity of the first pin itself, and it can be ensured that after the first connecting plate and the second connecting plate are plugged in, the second pin and the area of ​​the first pin not coated with the first insulating layer can still contact to achieve the conductive transmission effect between the first connecting plate and the second connecting plate.
