[0039] See also Figure 1 , Figure 1 FIG. 1 is a schematic diagram of a partial structure of a display device 100 in the prior art. Figure 1As shown, the display device 100 in the prior art mainly includes a display panel 10, a circuit board 30 and a core board 50. The display panel 10 is electrically connected to the circuit board 30 via a signal transmission line 20, and the circuit board 30 is electrically connected to the core board 50 via a connecting line 40. A part of the electronic components that control the display panel 10 to display the picture are arranged on the circuit board 30, and another part of the electronic components that control the display panel 10 to display the picture are arranged on the core board 50. At this time, the circuit board 30 needs to maintain electrical connection with the display panel 10 to realize signal transmission and control. The signal transmission line 20 can be a chip on film (COF).

[0040] Typically, in the prior art, the display panel 10 and the circuit board 30 are electrically connected using a signal transmission line 20, thereby achieving electrical connection between the circuit board 30 and the core board 50, thereby achieving signal transmission between the display panel 10 and the core board 50. Obviously, this connection method results in a more complex circuit structure. At the same time, the signal transmission line 20 and the circuit board 30 are usually electrically connected using a bonding process. The use of the signal transmission line 20 between the display panel 10 and the circuit board 30 greatly increases the difficulty of the bonding process, reduces the flexibility of production and manufacturing, and greatly increases the cost of manufacturing the display device 100.

[0041] Based on the above problems, the present application provides a display device, which integrates the electronic components originally set on the circuit board on the movement board (referred to as the driver in the following description) and uses a flexible printed circuit board (Flexible Printed Circuit board, FPC) to directly and flexibly connect the display panel and the driver, thereby simplifying the structure of the display device, reducing manufacturing costs, and improving production flexibility.

[0042] Please also refer to Figure 2 , Figure 2 FIG. 2 is a partial structural diagram of a display device 200 disclosed in an embodiment of the present application. Figure 2As shown, in the embodiment of the present application, the display device 200 may include at least a display panel 210 and a driver 230. The display panel 210 and the driver 230 are electrically connected via a flexible printed circuit board (FPC) 220 to enable control signal transmission between the display panel 210 and the driver 230. The display panel 210 is configured to display an image. Specifically, the driver 230 transmits a control signal to the display panel 210 via the flexible printed circuit board 220, and the display panel 210 displays an image based on the control signal.

[0043] In the embodiment of the present application, the display device 200 may be a liquid crystal display device, for example, a liquid crystal display (LCD), such as a thin film transistor liquid crystal display (TFT-LCD), etc., and the present application does not impose any specific restrictions on this.

[0044] In the specific embodiment of the present application, the display panel 210 includes a display area, a non-display area (not shown) located around the display area, and a drive area 211 disposed in the non-display area. The display area is used for image display, and the non-display area is used to arrange the drive circuit that drives the display area to perform image display.

[0045] Specifically, the display area includes a plurality of pixel units, each of which emits light to varying degrees to display an image. The drive area 211 may include a plurality of driver chips (ICs) 21a, which are used to drive the display panel 210 to display an image. The driver chips 21a may be connected to the plurality of pixel units through a bonding process to enable transmission of drive signals between the driver chips 21a and the pixel units.

[0046] In a specific embodiment of the present application, the driver 230 mainly includes electronic components for realizing functions such as energy supply and control. Specifically, the driver 230 includes a first electronic component group and a second electronic component group, wherein the first electronic component group includes some electronic components for controlling the display panel 210 to display the image (these electronic components are set on the circuit board in the prior art), and the second electronic component group includes another part of the electronic components for controlling the display panel 210 to display the image. It can be understood that the first electronic component group is a collection of multiple electronic components originally set on the circuit board 30, and the second electronic component group is a collection of multiple electronic components preset on the driver 230.

[0047] In the embodiment of the present application, the electronic components that are typically provided on the circuit board 30 in the prior art are integrated on the driver 230. Furthermore, there is no need to provide an additional circuit board 30 to house some of the electronic components, while still achieving signal transmission and image display functions. This effectively simplifies the structure of the display device 200 of the present application. Furthermore, the problem of using a bonding process to achieve electrical connection between the display panel 210 and the driver 230, which can easily cause the signal transmission line 20 to peel off and thus affect signal transmission, is avoided, effectively improving the display effect of the display device 200.

[0048] It is understandable that the driving member 230 may be a movement board or a movement board assembly, and may also include other electronic components and provide circuit connections for these electronic components. This application does not impose specific restrictions on this.

[0049] In a specific embodiment of the present application, the flexible printed circuit board 220 may be electrically connected to the driving chip 21 a of the display panel 210 , and the present application does not impose any specific limitation on this.

[0050] like Figure 2 As shown, in the embodiment of the present application, the display device 200 further includes a connector assembly 240. The flexible printed circuit board 220 is electrically connected to the driving member 230 via the connector assembly 240 to achieve control signal transmission and thus realize the image display function.

Based on the same concept, the present application also discloses an assembly method for the above-mentioned display device 200. Figure 3 As shown, in the embodiment of the present application, the assembly method of the display device 200 may include at least the following steps.

[0052] Step S1 : electrically connecting the driving chip 21 a of the display panel 210 to the pixel units of the display panel.

[0053] Specifically, in the embodiment of the present application, the driving chip 21 a can be connected to the plurality of pixel units through a binding process to achieve driving signal transmission between the driving chip 21 a and the pixel units.

[0054] Step S2 : electrically connecting the flexible printed circuit board 220 and the driving component 230 via the connector assembly 240 .

[0055] Step S3 : electrically connecting the flexible printed circuit board 220 to the display panel 210 to achieve control signal transmission between the display panel 210 and the driving component 230 .

[0056] Specifically, in the embodiment of the present application, the flexible printed circuit board 220 is electrically connected to the driving component 230 through the connector assembly 240, and then the flexible printed circuit board 220 is electrically connected to the display panel 210 to realize the control signal transmission between the display panel 210 and the driving component 230.

[0057] Please also refer to Figure 4 and Figure 5 , Figure 4 for Figure 2 FIG. 2 is a schematic diagram of a structural decomposition of a first specific embodiment of a display device 200 . Figure 5 for Figure 4 FIG. 1 is a schematic structural diagram of the assembled display device 200 .

[0058] like Figure 4 As shown, in this embodiment of the present application, the connector assembly 240 includes a first engaging structure 242 disposed at one end of the flexible printed circuit board 220 and a second engaging structure 243 disposed at one side of the driver 230. The first engaging structure 242 and the second engaging structure 243 are engaged with each other to electrically connect the flexible printed circuit board 220 and the driver 230, thereby enabling control signal transmission between the driver 230 and the flexible printed circuit board 220.

[0059] In the specific embodiment of the present application, the first engaging structure 242 is provided with a first engaging pattern for engaging and connecting, and the second engaging structure 243 is provided with a second engaging pattern on a side opposite to the first engaging structure 242. The first engaging pattern corresponds to and matches the second engaging pattern to ensure that the first engaging structure 242 and the second engaging structure 243 are aligned and engaged. In other words, the engaging pattern of the first engaging structure 242 and the engaging pattern of the second engaging structure 243 interlock with each other to achieve press-fit fastening and removal of the flexible printed circuit board 220 and the second engaging structure 243, that is, to achieve connection and disconnection of the flexible printed circuit board 220 and the driving member 230.

[0060] like Figure 4 and Figure 5 As shown, in some embodiments of the present application, the flexible printed circuit board 220 includes a first surface 221 and a second surface 222 relative to each other. Specifically, the first surface 221 can be the back surface of the flexible printed circuit board 220, and the second surface 222 can be the front surface of the flexible printed circuit board 220.

[0061] The first engaging structure 242 may be disposed at one end of the flexible printed circuit board 220 and close to the first surface 221 , and this application does not impose any specific limitation on this.

[0062] Please also refer to Figures 4 to 6 , Figure 6 for Figure 3 FIG. 1 is a flow chart of a first embodiment of step S2 in the assembly method shown.

[0063] The assembly method is used to assemble Figure 2 、 Figure 4 and Figure 5 The display device 200 shown in FIG. Figures 2 to 5 The embodiment shown has described the display device in detail, so it will not be repeated here. Figure 6 As shown, in the embodiment of the present application, step S2 of the assembly method “electrically connecting the flexible printed circuit board 220 and the driving member 230 through the connector assembly 240 ” includes at least the following steps.

[0064] Step S11 : disposing a first engaging structure 242 on the flexible printed circuit board 220 , and disposing a second engaging structure 243 engaged with the first engaging structure 242 on the driving member 230 .

[0065] In a specific embodiment of the present application, the first locking structure 242 is provided with a first locking line for locking connection, and the second locking structure 243 is provided with a second locking line on the side opposite to the first locking structure 242, and the first locking line corresponds to the second locking line to ensure that the first locking structure 242 and the second locking structure 243 are aligned and locked.

[0066] Step S12 : Electrically connecting the flexible printed circuit board 220 and the driving component 230 by engaging the first engaging structure 242 with the second engaging structure 243 .

[0067] In a specific embodiment of the present application, the engaging lines of the first engaging structure 242 and the second engaging structure 243 engage with each other to achieve the pressing, fastening and pulling out of the flexible printed circuit board 220 and the second engaging structure 243, that is, to achieve the connection and disconnection of the flexible printed circuit board 220 and the driving member 230.

[0068] In the embodiment of the present application, the first engaging structure 242 and the second engaging structure 243 are provided to achieve selective connection and disconnection between the flexible printed circuit board 220 and the driver 230. Therefore, there is no need to use a Chip On Film (COF) and a bonding process to achieve electrical connection between the display panel 210 and the driver 230, effectively reducing production and process costs while greatly improving the flexibility of the connection between the display panel 210 and the driver 230.

[0069] Please also refer to Figure 7 and Figure 8 , Figure 7 for Figure 2 FIG. 1 is a schematic diagram of a structural decomposition of a second specific embodiment of a display device 200 . Figure 8 for Figure 7 FIG. 1 is a schematic structural diagram of the assembled display device 200 .

[0070] like Figure 7 and Figure 8 As shown, in this embodiment of the present application, the connector assembly 240 includes a first connection joint (not shown) provided at one end of the flexible printed circuit board 220, a second connection joint 246 provided on one side of the driving member 230, and a retracting member 245 fixedly connected to the first connection joint. The first connection joint and the second connection joint 246 are aligned, and the retracting member 245 is tightened or loosened to connect or separate the first connection joint and the second connection joint 246, thereby selectively achieving electrical connection between the flexible printed circuit board 220 and the driving member 230.

[0071] It can be understood that the second connection connector 246 is provided with an accommodating space for accommodating the first connection connector. After the first connection connector is accommodated in the second connection connector 246, the shrinking member 245 is contracted to clamp the first connection connector and the second connection connector 246 together to achieve electrical connection and control signal transmission between the flexible printed circuit board 220 and the driving member 230.

[0072] In a specific embodiment of the present application, the retracting member 245 may be a retracting button, and the present application does not impose any specific limitation on this.

[0073] Please also refer to Figures 7 to 9 , Figure 9 for Figure 3 The assembly method is used to assemble the second embodiment of step S2. Figure 2 、 Figures 7 and 8 The display device 200 shown in FIG. Figure 2 、 Figures 7 and 8 The embodiment shown has described the display device in detail, so it will not be repeated here. Figure 9 As shown, in the embodiment of the present application, step S2 of the assembly method of the display device 200 , “electrically connecting the flexible printed circuit board 220 and the driving member 230 via the connector assembly 240 ”, includes at least the following steps.

[0074] Step S21 : a first connection connector is provided on the flexible printed circuit board 220 , and a second connection connector 246 is provided on the driving member 230 to engage with the first connection connector.

[0075] In some embodiments, the second connection joint 246 is provided with a receiving space for accommodating the first connection joint. After the first connection joint is accommodated in the receiving space of the second connection joint 246, the shrinking member 245 is shrunk to clamp the first connection joint and the second connection joint 246.

[0076] Step S22 : Tighten the shrinking member 245 of the connector assembly 240 to connect the first connection joint and the second connection joint 246 , so as to achieve electrical connection between the flexible printed circuit board 220 and the driving member 230 .

[0077] In the embodiment of the present application, the first connection joint and the second connection joint 246 are aligned, and the shrinking member 245 is tightened or loosened to connect or loosen the first connection joint and the second connection joint 246 to selectively achieve electrical connection between the flexible printed circuit board 220 and the driving member 230.

[0078] In the embodiment of the present application, the first connection joint, the second connection joint 246, and the retracting member 245 are provided, the first connection joint and the second connection joint 246 are aligned, and the first connection joint and the second connection joint 246 are connected or released by tightening or releasing the retracting member 245, thereby selectively achieving an electrical connection between the flexible printed circuit board 220 and the driver 230. The above-mentioned plug-in method is used to connect or release the flexible printed circuit board 220 and the driver 230, thereby eliminating the need to use a chip-on-film and a bonding process to achieve an electrical connection between the display panel 210 and the driver 230, effectively reducing production and process costs while greatly improving the flexibility of the connection with the driver 230.

[0079] Please also refer to Figures 10 to 12 , Figure 10 for Figure 2 FIG. 1 is a schematic structural diagram of a driving member 230 of a third specific embodiment of a display device 200 . Figure 11 for Figure 2FIG. 1 is a partial structural diagram of a third specific embodiment of a display device 200 . Figure 12 for Figure 2 FIG. 1 is a schematic structural diagram of the third embodiment of the display device 200 after assembly.

[0080] like Figure 11 and Figure 12 As shown, in the embodiment of the present application, the connector assembly 240 is a connector 248, and the flexible printed circuit board 220 and the driving member 230 are electrically connected via the connector 248. The connector 248 is partially or fully embedded in the driving member 230, and a connection port for connecting to the flexible printed circuit board 220 is exposed.

[0081] In a specific embodiment of the present application, the connector 248 includes two connection ports arranged opposite to each other, which are respectively used to connect to the flexible printed circuit board 220 and the driving member 230.

[0082] like Figure 10 and Figure 11 As shown, a notch 231 is defined on one side of the driver 230, into which the connector 248 is inserted. In some embodiments, the surface of the connector 248 adjacent to the driver 230 is flush with the bottom wall of the notch 231. This reduces the height of the connector 248 connected to the driver 230, thereby reducing the space occupied by the connector 248 on the driver 230. This improves the space utilization of the driver 230 and enhances the simplicity of the connection structure.

Figure 2 、 Figures 10 to 12 The display device has been described in detail in the embodiment shown, and will not be described again here.

[0084] like Figure 13 As shown, in the embodiment of the present application, step S2 of the assembly method of the display device 200 , “electrically connecting the flexible printed circuit board 220 and the driving member 230 through the connector assembly 240 ,” includes at least the following steps.

[0085] In step S31 , a notch 231 is formed on one side of the driving member 230 , and the connector 248 of the connector assembly 240 is inserted into the notch 231 .

[0086] In some embodiments, a surface of the connector 248 on one side near the driver 230 is flush with the bottom wall of the notch. This reduces the height of the connector 248 connected to the driver 230, thereby reducing the space occupied by the connector 248 on the driver 230, thereby improving the space utilization of the driver 230 and enhancing the simplicity of the connection structure.

[0087] Step S32 : electrically connecting the flexible printed circuit board 220 and the driving component 230 via the connector 248 .

[0088] In a specific embodiment of the present application, the connector 248 includes two connection ports that are arranged opposite to each other, and the two connection ports are used to electrically connect to the flexible printed circuit board 220 and the driving member 230 respectively.
